Hierarchy of Controls Definitions

Elimination

Substitution

This control measure involves eliminating or removing the risk in its entirety

This form of control involves substituting a safer process or material for the hazardous process/material found.

Isolation

Engineering

This control involves separating the hazard or hazardous work practice from employee’s other work areas. This may involve sectioning off the area by erecting barriers or by moving either the hazardous work practice or the „other‟ employees and their work practices.

This method of control involves designing and/or adding physical safety features to plant or equipment.

Admin

PPE

This type of control is most effective when used in conjunction with measures mentioned above or as an interim control whilst more effective control measures are developed and implemented.

PPE is not a particularly effective control method and should only be used:

• When all other control measures are impractical; or

• In conjunction with other more effective, control measures.

Preventing fire or explosion when storing and transporting cylinders

• Fire

• Explosion

• Damage to persons and property L2 C2 MR LR

• Close the cylinder valves when the equipment is not in use.

• Always provide adequate ventilation during welding and cutting operations.

• Store gas cylinders outside whenever possible, or in a well-ventilated place.

• Avoid taking gas cylinders into poorly ventilated rooms or confined spaces.

Workers

Training

• Oxy/fuel equipment is relatively easy to use but users may still need some instruction or training

Check for leaks

• Small leaks may not be detected immediately.

L3 C3 LR LR

• The safe use of the equipment, including the correct methods to purge, light and shut down.

• General safe working practices and the precautions to take.

• When and how to use the fire extinguishers

• Information about escape routes, how to raise the fire alarm and emergency procedures.

• Use a proprietary leak detecting spray or solution suitable for use with oxy/fuel systems. Do not use soapy water or solutions containing grease or oils on oxygen systems.

• Never look for gas leaks with a naked flame.

• Immediately repair or replace leaking components.

Workers

L3 C3 LR LR

Workers

• Leaking hoses should not be repaired.

• If a cylinder leaks when the valve is closed move the cylinder outside if safe to do so and away from sources of ignition (naked flames, sparks, electric motors, etc.) Prevent unauthorised access and notify the cylinder supplier immediately.

Fumes created during flame cutting

• Inhalation of toxic substances

• Try to work in a position where the wind blows the fume cloud away from you and other people.

• If you flame cut indoors or in conditions were there is little air movement, the need for extraction and/or RPE depends on how much cutting you are going to do.

L2 C2 HR LR

Workers

• Automated flame cutting machines, particularly multi-head machines, will normally need fume extraction fitted to them.

• Work on materials coated with lead or chromate paints, galvanised or cadmium plated, or metal contaminated with oil, grease etc. are likely to require fume control such as extraction and/or RPE.

Preventing fire from heat, sparks, molten metal or direct contact with flame

• Fire

• Damage to persons and property

L2 C2 HR LR

• Move the workpiece to a safe location for carrying out hot work.

• Remove nearby combustible materials (such as flammable liquids, wood, packaging, or plastics)

• Protect nearby combustible materials that cannot be moved.

• Prevent flame, heat, sparks or hot spatter from landing on the hoses.

• Keep fire extinguishers nearby.

Preventing Fire/explosion caused by gas leaks

• Highly flammable gases

• Explosions from mixtures of air and oxygen

• Poorly ventilated workplaces

• Fire

• Explosions

• Property damage

L2 C2 HR LR

• Turn the gas supply off at the cylinder when the job is finished or before the cylinders are moved or transported.

• Isolate and purge or remove hoses and equipment from enclosed or poorly ventilated spaces when there is a break in work.

• Keep hoses away from sharp edges and abrasive surfaces or where vehicles can run over them.

• Do not allow hot metal or spatter to fall on hoses.

• Maintain all equipment and regularly check its condition

Backfires

• Explosion

• If a backfire does occur:

• Shut off the torch valves, oxygen first (usually coloured blue) and then the fuel gas (usually coloured red)

L2 C2 HR LR

Workers

• Shut off the oxygen and fuel gas cylinder valves.

• Cool the blowpipe with water if necessary.

• Check the equipment for damage or faults, particularly the nozzle.

Flashbacks

•

Explosion

L2 C2 HR LR

• Use the correct lighting-up procedure. Purge the hoses before lighting the torch to remove any potentially explosive gas mixtures. Use a spark igniter and light the gas quickly after turning it on.

• Make sure the blowpipe is fitted with spring-loaded non-return valves.

• Use the correct gas pressures and nozzle size for the job.

• Maintain the equipment in good condition.

• Fit flashback arresters to both the oxygen and fuel gas hoses near to the regulators

• For long lengths of hose, fit arresters on both the torch and the regulator.

If a flashback does occur:

• If it is safe to do so, close the cylinder valves on both fuel gas and oxygen.

• If the fire cannot be put out at once, evacuate the area and call the emergency fire services.
