CRYSTALLINE SILICA INFORMATION

INTRODUCTION

Following the introduction of the engineered stone ban around the country from 1st July this year, new rules when working with silica products have come into effect from 1 September 2024.

The new laws will impact the carrying out of general day-to-day tasks with working with crystalline silica substances (CSS) such as

• cutting floor and wall tiles,

• cutting or grinding concrete,

• cutting, trimming and drilling into bricks or roof tiles,

• cutting or drilling autoclaved aerated concrete (Hebel), etc.

This will include a requirement to control the processing of a CSS by specified means, for example, isolation, wet dust suppression, on-tool extraction or local exhaust ventilation.

Orbit are encouraging all our contractors who’s work involve the above listed tasks to become familiar with these new requirements in ensuring workers on site are across the new provisions.

What products do the new laws apply to?

A CSS is any material that contains at least 1% crystalline silica, determined by weight. It includes materials such as:

• natural stone products such as marble, granite, sandstone,

• sintered stone,

• porcelain products,

• asphalt,

• cement, mortar, render and grout,

• concrete, concrete blocks and fibre cement products,

• autoclaved aerated concrete (Hebel)

• bricks,

• pavers and tiles including roof tiles.

What should you do next?

When working with any of the products or materials listed above or any other material that contains at least 1% crystalline silica you must:

1. Control the processing of the product or material.

2. Assess if the processing of the product or material is classified as High Risk Crystaline Silica Work (HRCSW)

I have attached a document which is to be used when identifying whether the work or task is classified as HRCSW “High Risk Crystaline Silica Work Identification Management”

Also attached is a “Preparing Crystaline Silica Hazard Control Statement” which is to be used when you have identified the work or task is HRCSW.

As contractors for Orbit you must control the risks associated with exposure to crystalline silica by applying the hierarchy of control in Part 4.1 (Hazardous substances) of the OHS Regulations.

An employer must, so far as is reasonably practicable, eliminate the risks associated with exposure to crystalline silica dust in their workplace.

If it is not reasonably practicable to eliminate a risk associated with crystalline silica, the employer must reduce the risk so far as is reasonably practicable by:

• substitution, for example, instead of using engineered stone which can be up to 95% silica, use natural stone, which can have a much lower silica content

• isolation, for example using automated wet machines

• engineering controls, for example using on-tool water suppression, or

• a combination of any of these risk control measures

If the risks from exposure still remain after the listed risk control measures have been implemented, administrative controls must be used to reduce the risk so far as is reasonably practicable. Administrative controls include, for example, rotation during shifts between high and low-exposure tasks.

Worksafe have put together eight videos that have been developed (5 currently published), focusing on crystalline silica management in the workplace. The video series provides duty holders with practical information and guidance on hazard identification, risk control measures, atmospheric monitoring, and health monitoring. While the video series is primarily targeted to duty holders in the construction industry, the information and guidance can be applied across most industries who work with crystalline silica.

You can find the series of videos here: https://www.youtube.com/playlist?list=PL8jTfq7I4pElZbh3yCT1_Z0TZBp-Q3YU5

Worksafe have also published a very in depth guidance document which has all the information you need as well as the above videos in the document, so please click in the this link: Preventing exposure to crystalline silica dust | WorkSafe Victoria

Please ensure you read and understand the listed information as this affects you and your workers health.

High risk crystalline silica work assessment duties

Find further information about hazard control statements under the heading, Hazard control statement duties.

The employer or self-employed person must keep a copy of the written record. The copy must be kept for the entire time the crystalline silica process is happening at the workplace. Copies can be kept in electronic format.

High risk crystalline silica work assessment duties

If doing a risk assessment, the employer or selfemployed person must take into account the following factors:

• The specific tasks or processes being done with material that contains crystalline silica.

• The form of crystalline silica to be used, for example, brick, concrete, crushed rock.

• The specific tasks or processes being done with material that contains crystalline silica.

• The proportion of crystalline silica in the material.

• Previous atmospheric monitoring results.

• The form of crystalline silica to be used, for example, brick, concrete, crushed rock.

• The likely frequency and duration of exposure to crystalline silica dust.

• The proportion of crystalline silica in the material.

• Previous atmospheric monitoring results.

• The likely frequency and duration of exposure to crystalline silica dust.

• Any information about incidents, illnesses or diseases associated with exposure to crystalline silica dust at the workplace.

Determining whether the exposure of an employee exceeds half the exposure standard must be done without taking into account any controls in place that would reduce exposure.

Note: In conducting this risk assessment, it is not sufficient to rely on the effect of risk control measures that are implemented in accordance with the hierarchy of controls described in this guidance. This means that, for example, even if you are using on-tool dust extraction to control exposure to crystalline silica dust, you still need to undertake a risk assessment as described in this guidance or choose to identify that work as high risk crystalline silica work.

An employer must also make the written record readily accessible during the same period to:

• any employee who may be exposed to crystalline silica dust, and

An employer must also make the written record readily accessible during the same period to:

• relevant health and safety representatives (HSRs).

• any employee who may be exposed to crystalline silica dust, and

• relevant health and safety representatives (HSRs).

If an employer or a self-employed person cannot identify whether a crystalline silica process is HRCSW, the process must be treated as HRCSW. The process must be treated as HRCSW until the employer or selfemployed person can establish that it is not HRCSW.

Hazard control statement duties

An employer or a self-employed person must not perform HRCSW unless:

Additional duties in relation to high risk crystalline silica work

An employer must ensure that an applicant who applies for work involving HRCSW is given information about:

Additional duties in relation to high risk crystalline silica work

• the health risks associated with exposure to crystalline silica dust

An employer must ensure that an applicant who applies for work involving HRCSW is given information about:

• the need for measures to control those risks, and

Hierarchy of controls

The hierarchy of controls is a step-by-step approach to eliminating or reducing risks. It ranks risk controls from the highest level of protection and reliability through to the lowest and least reliable.

Eliminate the risk

• details of the control measures.

• the health risks associated with exposure to crystalline silica dust

• the need for measures to control those risks, and

Information, instruction and training

• details of the control measures.

Eliminate the risk

Where there is any risk associated with silica dust at the workplace, employers must first seek to eliminate that risk so far as is reasonably practicable. For example, by using materials that do not contain crystalline silica.

Reduce the risk

Information, instruction and training

An employer must ensure that employees who are likely to be exposed to risks associated with HRCSW are given information, instruction and training in:

• the health risks associated with exposure to crystalline silica dust, and

An employer must ensure that employees who are likely to be exposed to risks associated with HRCSW are given information, instruction and training in:

• the need for, and proper use of, any risk control measures and how they are to be implemented.

• the health risks associated with exposure to crystalline silica dust, and

Reduce the risk

If a risk cannot be eliminated, it must be reduced so far as is reasonably practicable. The risk can be reduced by doing one or a combination of the following:

• Substituting materials containing crystalline silica with a substance that is less hazardous, or a less hazardous form of crystalline silica. For example, materials with a lower crystalline silica content.

Is a pre-prepared hazard control statement acceptable?

• the need for, and proper use of, any risk control measures and how they are to be implemented.

Is a pre-prepared hazard control statement acceptable?

A pre-prepared hazard control statement is only acceptable if it has been adapted to the individual workplace and the specific HRCSW taking place at that workplace. Employers and self-employed persons will need to review the hazard control statement on-site. They will need to ensure it meets all the requirements set out in this guidance.

Selecting risk control measures for high risk crystalline silica work

• Isolating people from the source of exposure to silica dust. For example, by restricting the work to an enclosed cabin.

• Using engineering controls. For example, hand-held tools with on-tool water suppression or on-tool dust extraction.

Administrative controls

• Using engineering controls. For example, hand-held tools with on-tool water suppression or on-tool dust extraction.

Administrative controls are work methods or procedures designed to minimise exposure to a hazard.

Administrative controls are work methods or procedures designed to minimise exposure to a hazard.

Selecting risk control measures for high risk crystalline silica work

When selecting measures to control the risks associated with HRCSW, an employer must apply the hierarchy of controls set out in the OHS Regulations.

Specific duties and risk control measures must be complied with when working with engineered stone. Find more information see under the heading, Required controls when carrying out an engineered stone process.

If, after using the listed controls, a risk to health associated with silica dust remains, employers must reduce the risk with administrative controls. Again, they must reduce the risk so far as is reasonably practicable. Examples of administrative controls include:

• reducing the duration and frequency of exposure through job rotation

• good housekeeping practices, including regular cleaning of work areas with H or M-class vacuums or water.

Preparing a crystalline silica hazard control statement for high risk crystalline silica work

Personal protective equipment

If, after using administrative controls, a risk to health associated with silica dust remains, employers must reduce that risk. They must again reduce the risk so far as is reasonably practicable. This time they must reduce the risk by providing appropriate personal protective equipment (PPE) to employees at risk. For example, respiratory protective equipment such as a half-face negative respirator or powered air purifying respirator (PAPR).

Integrated water delivery system

An integrated water delivery system, also known as on-tool water suppression, is one of the most effective ways to reduce exposure to crystalline silica dust.

Effective control of risks to health will most likely require a combination of control measures.

Note: Employers must, so far as is reasonably practicable, consult with affected employees and any HSRs when identifying hazards or making decisions about measures to control risk.

Required controls when carrying out an engineered stone process

When power tools are used

There are specific controls required when doing permitted work with engineered stone.

The uncontrolled dry cutting, grinding and abrasive polishing of engineered stone is not permitted in Victoria. There are specific controls required when doing permitted work with engineered stone.

When a power tool or other form of mechanical plant is used to undertake an engineered stone process, an employer or self-employed person must ensure plant is used with:

• an integrated water delivery system that meets the requirements set out in this guidance, or

• an on-tool dust extraction system that meets the requirements set out in this guidance, or

• an integrated water delivery system that meets the requirements set out in this guidance, or

• if these controls are not reasonably practicable, another form of local exhaust ventilation (LEV).

• an on-tool dust extraction system that meets the requirements set out in this guidance, or

• if these controls are not reasonably practicable, another form of local exhaust ventilation (LEV).

An integrated water delivery system, also known as on-tool water suppression, is one of the most effective ways to reduce exposure to crystalline silica dust.

Water is used at the point of dust generation to dampen down or suppress dust before it is released into the air.

An integrated water delivery system must:

Water is used at the point of dust generation to dampen down or suppress dust before it is released into the air.

An integrated water delivery system must:

• deliver a continuous supply of water to the point of contact with the stone while the power tool or mechanical plant is in use, and

• if the system uses recycled or recirculated water, adequately treat that water.

• deliver a continuous supply of water to the point of contact with the stone while the power tool or mechanical plant is in use, and

On-tool dust extraction

• if the system uses recycled or recirculated water, adequately treat that water.

On-tool dust extraction

On-tool dust extraction removes the dust from the source as it is being produced. It is fitted directly onto the tool, with extraction attached to a high efficiency particulate air (HEPA) filtered Dust Class H vacuum cleaner.

An on-tool dust extraction system must:

• be commercially available, and

An on-tool dust extraction system must:

• be commercially available, and

• be connected to a Dust Class H vacuum or another system that captures any dust generated by the power tool.

Dust Class H vacuum means a vacuum that complies with the Class H requirements in AZ/NZS 60335.2.69:2017 Household and similar electrical appliances—Safety— Part 2.69: Particular requirements for wet and dry vacuum cleaners, including power brush, for commercial use or its equivalent.

Local exhaust ventilation

Local exhaust ventilation (LEV) is an engineering control that captures the emission of an airborne contaminant at its source and transports it to a safe emission point, filter or scrubber. On-tool dust extraction is one form of LEV.

Another form of LEV should be used with power tools when integrated water delivery system, or on-tool dust extraction are not reasonably practicable.

Preparing a crystalline silica hazard control statement for high risk crystalline silica work

Local exhaust ventilation systems such as hoods, booths or extraction walls extract airborne dust from processing areas. While these controls may reduce background levels of silica dust, they are not as effective as water suppression or on-tool dust extraction in reducing the exposure of employees

Where an integrated water delivery system, on-tool dust extraction system or another LEV system is required, employers and self-employed persons must ensure those systems are designed, installed, used and maintained, so far as is reasonably practicable, to eliminate or reduce the risk of exposure to crystalline silica dust.

Respiratory protective equipment

Employers must provide an employee who undertakes an engineered stone process with respiratory protective equipment (RPE) that:

Prohibition on cleaning with compressed air and gases

An employer or a self-employed person must not use compressed air or other compressed gases to clean the following, unless the use of that air or gas does not result in a concentration of respirable crystalline silica that exceeds the exposure standard for crystalline silica:

• a work area where an engineered stone process has been undertaken, or

The employer must also ensure the employee uses the RPE.

Employers need to provide employees with information, instruction and training in the use, fit and maintenance of RPE, including the system for storage.

Examples of how to control risks

Example 1: Cutting concrete footpath

Example 2: Cutting a hole in an engineered stone kitchen splash back

Examples of how to control risks

Example 1: Cutting concrete footpath

An employee needs to use a concrete cutting saw to cut a section of footpath. A search of the internet for concrete lists washed sand as an ingredient. Sand contains over 95% crystalline silica (quartz). It is known that concrete may contain 25% to 40% of washed sand.

The job will take one day to complete and it is known that dry cutting of concrete can produce high levels of dust. Cutting concrete is a crystalline silica process. It is unknown what the employee’s actual exposure to silica dust will be from the cutting, so the crystalline silica process is identified by the employer as HRCSW. The employer needs to ensure a hazard control statement is prepared, in consultation with employees, and implemented to minimise exposure to crystalline silica dust for employees and pedestrians.

Risk control measures identified in the hazard control statement and implemented by the employer include on-tool water suppression, preventing access to the work area, good housekeeping during the work and at the completion of the task, ensuring wet residue is not permitted to remain in the area to dry.

Example 2: Cutting a hole in an engineered stone kitchen splash back

An employee needs to create a hole in a previously installed engineered stone splash back to install a new power point, as part of a kitchen renovation. The employee will need to use a power drill and grinder to create the hole. Cutting into engineered stone is an engineered stone process. The employer does not need to do a risk assessment as working on an engineered stone panel, slab or benchtop is automatically classed as HRCSW. This means that before starting work, the employer must ensure that a hazard control statement is prepared.

The employer must identify and capture the following risk control measures in the hazard control statement. Employers must ensure that:

• Power tools are fitted with:

Example 3: Demolition of large-scale structure

A contractor wins a job to demolish a large structure consisting of bricks and cement-based products. The work will involve using a hammer attachment on an excavator to demolish the structure. There is an overhead electrical power line within 4 m of a perimeter wall to be demolished. Due to this, an electrical spotter is required to spot for the excavator operator while the excavator is within 3 m to 6.4 m of the powerline.

The contractor identifies the demolition task as a crystalline silica process because of the use of mechanical plant to crush the materials, which contain crystalline silica.

The contractor conducts a risk assessment by doing the following things:

• Searches the internet to identify the likely silica content of the bricks and cement being demolished and finds a WorkSafe webpage that states that bricks and cement may contain 25% to 40% crystalline silica.

The contractor conducts a risk assessment by doing the following things:

• Consults with their employees and conducts a risk assessment. The risk assessment identifies that half of the respirable crystalline silica exposure standard may be exceeded, not taking into account any controls proposed to be used.

The contractor makes a written record describing the matters that were taken into account and identifies the work as HRCSW.

The contractor develops a hazard control statement that lists and uses the following risk control measures:

• A water-spraying system will be attached to the hammer to produce a fine mist to suppress dust at the working area.

The contractor develops a hazard control statement that lists and uses the following risk control measures:

• A water-mist fan will be used to provide further fine water spray to the working area.

• A water-mist fan will be used to provide further fine water spray to the working area.

Preparing a crystalline silica hazard control statement for high risk crystalline silica work

•The excavator cabin:

– is retrofitted with HEPA filters to reduce the risk of respirable crystalline silica being drawn into the cabin

– will be enclosed and the doors and windows kept shut, air flow will be put on recirculation and the cabin will be cleaned every day using water or a H or M-class industrial vacuum.

•Atmospheric monitoring of the excavator cabin is done to ensure the controls are managing the risk of exposure.

•An exclusion zone will be set up around the working area to prevent other people being exposed to the airborne dust.

•The electrical spotter will wear a P2 reusable respirator, be clean shaven, trained in how to use, store and maintain the respirator and will perform a fit check after putting the respirator on.

Example 4: Landscaping and high risk construction work

An employee is required to cut sandstone tiles with a brick saw as part of the landscaping works of a residential property under construction.

The supplier of the sandstone pavers has provided the employer with information that the sandstone pavers contain 80% crystalline silica. The task of cutting of the sandstone is a crystalline silica process.

The employer identifies the crystalline silica process as HRCSW.

An employee is required to cut sandstone tiles with a brick saw as part of the landscaping works of a residential property under construction. The supplier of the sandstone pavers has provided the employer with information that the sandstone pavers contain 80% crystalline silica. The task of cutting of the sandstone is a crystalline silica process.

The employer identifies the crystalline silica process as HRCSW.

The landscaping activities also involve movement of a small excavator backfilling trenches and moving soil on site at the same time. These activities are high risk construction work.

The employer has documented a SWMS, in consultation with employees and the HSR, for the landscaping activities and has included the required elements of a hazard control statement into their SWMS.

The information provided by the supplier of the sandstone states that a brick saw should be used with on-tool extraction attached to either a class H or M vacuum to reduce the risk of exposure to respirable crystalline silica. The employer puts this control requirement into the SWMS and purchases the required on-tool extraction and industrial vacuum before starting the job.

The employee using the equipment is given information about the health risks associated with exposure to crystalline silica dust and trained on how to use the on-tool extraction and industrial vacuum before starting the job, as well as how to empty the industrial vacuum.

Risk controls specified by the Occupational Health and Safety Regulations 2017

Selecting risk controls

Any risk to health or safety must be eliminated. If it is not reasonably practicable to eliminate the risk, it must be reduced so far as is reasonably practicable.

Eliminate the risk –most effective Use materials that do not contain crystalline silica. Do this so far as is reasonably practicable.

• Substituting the substance with a less hazardous substance, or a less hazardous form of the substance. For example, use materials that contain a lower crystalline silica content.

Eliminate the risk –most effective

Use materials that do not contain crystalline silica. Do this so far as is reasonably practicable.

Reduce the risk –less effective

Reduce the risk –less effective If it is not reasonably practicable to eliminate the risk, reduce the risk by:

If it is not reasonably practicable to eliminate the risk, reduce the risk by:

• Substituting the substance with a less hazardous substance, or a less hazardous form of the substance. For example, use materials that contain a lower crystalline silica content.

• Isolating people from the hazard. For example, using automated wet machines.

• Use engineering controls. For example, use power tools fitted with on-tool water suppression or on-tool dust extraction.

• A combination of any of the previously listed risk control measures.

• If a risk to health and safety remains, use administrative controls to reduce the risk. For example, good housekeeping and waste management practices, task rotation and warning signs.

• If a risk remains after using substitution, isolation, engineering and administrative controls, the risk must be reduced with personal protective equipment (PPE). For example, respiratory protective equipment such as half-face negative respirators or powered air-purifying respirators, eye protection and protective clothing.

More effective

Less effective

Using administrative controls and PPE to reduce risks does not control the hazard at the source. Administrative controls and PPE rely on human behaviour and supervision. Used on their own, they tend to be least effective in minimising risks.

What are the processes involved?

List the work processes in logical order.

What are the hazards and risks? What aspects of the work could harm workers or the public?

For example: Inhalation of respirable crystalline silica dust from:

• cutting a concrete footpath

• cutting a hole in an engineered stone kitchen splash back

• demolition of large scale structure

What are the risk control measures and how will they be implemented?

Describe what will be done to make the process as safe as possible?

• cutting sandstone tiles with a brick saw as part of the landscaping works, which may result in adverse health effects, such as silicosis.

Work in the open air and within external openings (such as doors and windows in buildings) is recommended. Local mechanical ventilation/extraction may be required to control airborne dust levels. Unpowered hand tools generate less dust when cutting or sanding. If generated dust cannot be avoided follow personal protection recommendations. Use a vacuum fitted with a HEPA M class filter instead of sweeping when cleaning dust generated from concrete panels.

Section 4: First Aid Measures

Swallowed: Wash out mouth with cold clean water. DO NOT induce vomiting. Then drink water at significant levels and seek medical advice.

Eye: Thorough washing with much clean flowing water, preferably sterile, for at least 15 minutes. Seek medical attention immediately for thorough examination of eye surface. If wet concrete is plashed into eye, flush with flowing water and get urgent medical attention.

Skin: Remove heavily contaminated clothing, wash skin thoroughly with tepid water and non-abrasive soap if necessary and remove source of contamination. If irritation develops and persists, seek medical attention.

Inhaled: Remove source of contamination and move victim away from dusty area to fresh air. If irritation continues, seek medical advice.

First Aid Facilities: Eye wash and normal washroom facilities

Advice to Doctor: Advise of abrasive and alkaline nature and treat symptomatically or consult Poisons Information Centre. Wet concrete burns to skin/eyes may result in corrosive caustic burns. Ingestion of concrete is unlikely. Do not induce emesis or perform gastric lavage. Neutralization with acidic agents is not advised due to increased risk of exothermic burns. Water-mineral oil soaks may aid in removing hardened concrete from skin. Ophthalmological opinion should be sought for ocular burns.

° Hazards from combustion products : Nil

° Suitable extinguisher media : Not applicable

° Special protective precautions and equipment for fire fighters : Nil

° Hazchem code : None allocated

° Concrete is stable and will not burn or explode.

Section 6: Accidental Release Measures

Spills and Disposal:

° When spills do occur, most material is best removed by mechanical means (sweepers/vacuums) wherever possible (shovel into containers).

° Avoid dust generation – wetting down may assist control measures.

° Removal should occur as soon as possible due to the setting involved. The spillage can and will bond to other surfaces unless removed quickly. Damage may involve deterioration of the surface due to the high pH.

° Final cleaning up of cement paste from surfaces may require sluicing with water

° Exposure control and personal protection recommendations should be followed during spill cleanup

° Prevent spillage or wash down water from entering drains, sewers, stormwater and water courses, pipes, etc.

Safety Data Sheet Conc rete

° If contamination of drains or watercourses has occurred, advise the relevant state environment protection agency and the company.

° Concrete (plastic) – concrete/washout waste must be disposed of in accordance with local authority regulations

° Concrete (dry) waste may be disposed of as inert landfill in accordance with local authority regulations.

Section 7: Handling and storage

Storage Precautions: No special storage requirements. Premixed concrete normally only has a usable life of several hours from the time of initial mixing to final placing where required in the product or the structure. Premixed concrete is adversely affected by contact with excess water and organic materials such as sugar which will delay setting and early strength development.

T Transport: Not classified as a Dangerous Goods

H Handling: Prevent all contact with the skin and maintain high standard of personal hygiene – always wash hands before eating, drinking, smoking or using the toilet. Wet concrete is heavy and appropriate manual handling risk control is required for barrowing, shoveling or carrying quantities of wet concrete When cutting using powered tools on dry concrete, dust containing respirable crystalline silica can be generated. Controls to prevent inhalation of dust are detailed in Section 8.

P Proper Shipping Name None allocated

Section 8: Exposure Controls/Personal Protection

The following applies to Dust from this product:

Exposure Limits:

Workplace Exposure Standards (WES) for airborne contaminants – Safe Work Australia

Keep exposure to dust as low as practicable and below the following WES:

- Crystalline Silica: 0 05mg/m3 TWA (time weighted average) as respirable dust.

Total dust NOS (not otherwise specified (of any type or particle size): 10mg/m3 TWA as inhalable dust

- Chromium VI (hexavalent) 0.05mg/m3 – sensitiser – as respirable dust

Engineering Controls

° Avoid generating dust and inhaling dusts and minimize exposure to dust.

° Provide adequate mechanical ventilation and/or local dust extraction or water spray to control airborne dust levels.

° Clean work areas regularly by wet sweeping and vacuuming in restricted areas and where there are strong winds

° Work in well ventilated area and wear PPE.

° Note – all occupational exposures to atmospheric contaminants should be kept as low as possible and be below the Workplace Exposure Standard (WES)

E Eye Protection:

° Splash resistant S Safety Glasses with side shields, safety goggles/face shields where splashing may occur or dust is likely. AS/NZS 1336 & 1337

° Plastic concrete/plastic washout waste will cause severe irritation with eyes and alkaline properties may produce severe alkali burns or serous eye damage

° Dry concrete dust may cause mechanical irritation, redness

Skin Protection:

° Wear f full clothing covering sections of body likely to come in contact with concrete and/or wet concrete washout waste during handling and placing including use of sleeves, long trousers, impervious boots, suitable protective/impervious gloves etc. Wash work clothes regularly and use barrier cream on hands

° Prevent all contact with skins; never kneel in wet concrete or allow extended contact of skin with wet concrete

° To avoid contamination of face and lips and ingestion, wash hands before eating, drinking, or smoking.

° Contact with plastic concrete / washout waste will cause severe irritation and possible chemical burns, cement dermatitis and dry skin. Portland cement is alkaline in nature so plastic concrete and plastic concrete washout waste are strongly alkaline which are harmful or caustic to the skin and may produce alkali burns.

Respirator Type

° Where engineering controls are not enough to minimize exposure to total dust and to respirable crystalline silica, p personal respiratory protection may be required. Depending on the work circumstances, a suitable P2 particulate

Safety Data Sheet Conc rete

respirator chosen and used in accordance with AS/NZS 1715 and AS/NZS 1716 may be sufficient, however where higher levels of dust are encountered cartridge or powered types of respirators may be necessary.

° Where dust levels are approaching or exceeding the WES above greater respiratory protection may be required.

Section 9: Physical and Chemical Properties

Appearance:

Concrete is typically grey in colour unless pigmented. When first mixed, it is described as being in a plastic or mouldable state and its condition is influenced by the raw materials in use and the amount of water used. It can range from an earth dry to a flowing condition. It has the typical appearance of stone or gravel mixed in a mortar containing cement paste. Concrete can set and harden.

Boiling Point: Not available

V Vapour Pressure: Not available

Freezing/Melting Point Melting point > 12000C

S Specific Gravity (H2O=1) 2.5

Flamm Limits: Not applicable

Vapour Density Not applicable

Auto-ignition temperature: Not applicable

Solubility (other) Not applicable

Solubility in Water Forms Slurry- alkaline (caustic) solution (pH>11)

F Flash Point: Not applicable

Odour

Particle Size

Some additives used may create a smell of ammonia

a proportion of the dust may be respirable (below 10 microns) –if airborne, becomes an exposure if inhaled

p pH Value: The pH of freshly mixed concrete is generally > 10; in its dry state >7.

Bulk Density: 1900 to 2600 kg/m3 (typical range)

V VOC Content: not available

Section 10: Stability and Reactivity

Stability:

Stable. The final setting time is influenced by many factors including the temperature and this can be up to 10-12 hours later. Strength development commences from that stage and continues almost indefinitely. Both setting and strength gain occur more slowly in cold weather than in hot weather. The setting process starts within minutes of the cement and water being mixed.

H Hazardous Polymerisation None

E Explosive Properties Not applicable

P Per Cent Volatiles: Not Available

A Autoignition Temp: Not Applicable

I Incompatible Materials None

H Hazardous Decomposition None

H Hazardous Reactors None

C Conditions to avoid Keep away from water; dust generation

Crystalline silica is stable, compatible with other materials and does not polymerise, and will not decompose into hazardous by-products

Section 11: Toxicological Information

Swallowed:

Unlikely in normal industrial situation. Acute if swallowed. Abrasive and mildly corrosive action. Highly irritant (burning) to mouth and throat. Symptoms may include nausea, stomach cramps and vomiting.

E Eye:

S Skin:

Acute to severe irritation. Abrasive and corrosive action. Symptoms include redness, stinging and lachrymation. Alkaline properties may produce severe alkali burns or serious eye damage. Dry concrete dust may cause mechanical irritation resulting in redness and lachrymation.

Acute. Skin irritation and possible chemical burns, cement dermatitis and dry/burning skin. Abrasive and corrosive action in the short term. (Portland cement is alkaline in nature making plastic concrete strongly alkaline – alkalines are harmful or caustic to the skin and may produce alkali burns; Portland cement is hygroscopic – it absorbs water - concrete needs water to harden so will draw water away from any other materials, including skin, and this will irritate and dry the skin).

Inhaled:

Safety Data Sheet Conc rete

Acute. Droplets or concrete dust may irritate the nose, throat and respiratory tract causing coughing, sneezing and breathing difficulties. Pre-existing upper respiratory or lung diseases including asthma and bronchitis may be aggravated Repeated inhalation of dust containing crystalline silica can cause bronchitis, silicosis (scarring of the lung) and may increase the risk of other serious disorders including scleroderma (disease of connecting skin tissue, joints, blood vessels and internal organs). Concrete is not listed as a carcinogen by ASCC; risk of cancer has not been identified by using concrete, however the International Agency for Research on Cancer (IARC) has classified Chromium VI (hexavalent) and Crystalline Silica inhaled in the form of quartz or cristobalite from occupational sources, as carcinogenic to humans Group 1.

L Long Term (Chronic) Exposure

Eyes – dust may cause inflammation of the cornea

S Skin – repeated contact causes irritation and drying of the skin and can result in persistent skin reddening and rash (dermatitis). Persons allergic to chromium could develop allergic dermatitis

I Inhaled - Inhalation of airborne particles from other sources in the work environment, including those from cigarette smoke, may cause the risk of respiratory diseases. It is recommended that all storage and work areas should be smoke-free zones and that other airborne contaminants should be kept to a minimum.

C Concrete Dust – long term exposure of crystalline silica dust above the WES carries potential risk of chronic health effects.

Section 12: Ecological Information

Ecotoxicity: Product forms an alkaline slurry when mixed with water

M Mobility: A low mobility would be expected in a landfill situation

Persistence & Degradability: Product is persistent and would have a low degradability

D Dust: Crystalline silica is non toxic to aquatic and terrestrial organisms; is not biodegradable; is insoluble and is expected to have low mobility in landfill

Section 13: Disposal considerations

Spills and leaks

Concrete in plastic form/washout waste – recover spilled materials into containers, but avoiding dust generation. Prevent substance /wash down water from entering waterways, drains or sewers. If contamination of drains or waterways occurs advise relevant state environment authority and the company

Disposal

° Take measures to prevent dust generation

° Concrete (plastic) - washout waste must be disposed of in accordance with local authority regulations.

° Concrete (dry) waste may be disposed of as inert landfill in accordance with local authority regulations.

Section 14: Transport

Transport is generally by mechanical equipment readily available in the industry. Transport equipment should be strong enough to contain a fluid with an effective specific gravity of 2.5

Section 15: Regulatory information

Exposure by inhalation to high levels of dust may be regulated under the Hazardous Substances Regulations as they apply to Respirable Crystalline Silica, requiring exposure assessment and control of inhalation exposure below the WES

Persons who have potential for exposure above the WES may be required by Regulations to have periodic health surveillance including chest x-ray (refer applicable State Govt Regulations).
