EFFECTS OF MOVEMENT CONTROL ORDER (MCO) ON A BUILDING’S INDOOR CONDITIONS

During the Movement Control Order (MCO), most non-essential office buildings were completely shut down for a long period of time.

Most of these buildings were not designed to be close down for anything longer than 48 hours. As the building are closed, the MVAC system of the building may have been turned off to curb the economic crisis due to the COVID-19 pandemic.

Prime Minister of Malaysia, YAB Tan Sri Muhyiddin Hj Mohd Yassin has announced the re-opening of the economic sector starting 4th May 2020. Re-opening buildings after MCO without knowing the risks that could affect the health of the employees, thus prevention must be considered now. Commissioning, maintenance, proper operation of buildings, and in particular, systems intended to control airborne infectious disease, are necessary for buildings and systems to be effective post MCO.

PREPARATION FOR BUILDING OPENING POST-MCO: THE NEED FOR INDOOR AIR QUALITY ASSESSMENT Upon returning to normalcy, a building with poor Indoor Air Quality is an environmental hazard and like all other hazards, it poses a risk to your employee’s health when the Movement Control Order (MCO) is lifted. If you don’t eliminate and control the hazard, it will affect the health of the employees. Thus, an Indoor Air Quality Assessment and/or Monitoring should be conducted during and after the reopening of offices to ensure the health of the employees upon returning to normalcy.

Factors that may affect post-MCO office indoor air quality:

1. Uneven levels of carbon dioxide and oxygen concentrations: Assuming the MVAC system is switched off or not properly maintained, there will be insufficient fresh air intake inside the workplace.

www.envirogroup.asia | version 1.0

BUSINESS CONTINUITY BUILDING ASSESSMENT, SANITISATION, PROTECTION & CERTIFICATION GUIDANCE FOR BUILDING OPERATIONS | COVID-19 PANDEMIC

2. Temperature differences and uneven distribution within the building: Thermal discomfort issues such as high air temperature, low air movement and stuffiness sensation may cause suffocation and distraction upon occupancy.

3. Low or high relative humidity High humidity will contribute to bacterial and mold growth while low relative humidity may cause static electricity, dry skin, throat and itchiness.

4. Build-up of Total Volatile Organic Compounds (TVOCs) For buildings that had undergone chemical disinfection, excessive and build-up of chemical vapour and gases may cause discomfort and have various health effects to the employees. Air fresheners, disinfectants and cleaning detergents are amongst the sources of TVOCs.

5. Bacteria and mold contamination With the optimum environment for microbial growth, indoor furniture or carpets may emit unpleasant odour and stain the interior surfaces such as ceiling panels and walls.

www.envirogroup.asia | version 1.0

BUSINESS CONTINUITY BUILDING ASSESSMENT, SANITISATION, PROTECTION & CERTIFICATION GUIDANCE FOR BUILDING OPERATIONS | COVID-19 PANDEMIC

THE ABOVE FACTORS CAN LEAD TO SICK BUILDING SYNDROME (SBS) WITH FOLLOWING SYMPTOMS:

Here are why a Post MCO IAQ Assessment is important: 1. To determine the Indoor Air Quality (IAQ) within the building Evaluation, quantifying and conclusion of the exposure level and its significance to health risk attributed to poor IAQ is critical upon re-opening. Neglecting to consider the impacts could delay the building’s re-opening because of the need for corrective action plans and remediation activities.

2. To evaluate the adequacy of MVAC existing performances A clean and well-maintained MVAC system is a must for better air cleaning efficiency as it plays a small role in infectious disease transmission, including COVID-19. The viruses can stay www.envirogroup.asia | version 1.0

BUSINESS CONTINUITY BUILDING ASSESSMENT, SANITISATION, PROTECTION & CERTIFICATION GUIDANCE FOR BUILDING OPERATIONS | COVID-19 PANDEMIC

airborne long enough to go all the way through the system and then pop out in somebody else’s office. Thus, prior to reoccupancy, it may be necessary to clean and disinfect interior occupied spaces, furnishings and the MVAC systems to reduce the health risk.

3. To recommend the next course of action for continual IAQ improvement A qualified Indoor Air Quality (IAQ) Assessor registered with the Department of Occupational Safety and Health (DOSH) is important to provide assistance in the assessment process and consultations regarding poor IAQ issues to prepare the facilities for the occupants to return to normalcy.

4. To prevent Building Related Illnesses (BRI) and Sick Building Syndrome (SBS) The last thing a building owner wants is another disease outbreak during the COVID-19 pandemic. A shortage of maintenance staff during MCO to operate the cooling towers and MVAC maintenance may allow the conditions to degrade and bacteria to grow. SBS is a condition attributed to poor IAQ. Failed attempts to prevent SBS will lead to decreased productivity among the staff, increased absenteeism, adverse health effects and further financial stress to the company.

IMPORTANCE OF SANITISATION & DISINFECTION: A COMPREHENSIVE METHOD AND VERIFICATION IS A MUST

SANITISATION Effective cleaning and sanitising in your premise and office buildings can help protect you and your employees against the spread of bacteria, viruses and other organisms. As the MCO extended for almost 2 months, microorganism build-up is a potential risk to employee’s health.

The most germ-laden spots in the offices were telephone, desktop, water dispenser handle, microwave, door handle, keyboard, mouse, pantry desk, reception counter, chair armrest, stationeries, etc.

With comparison to toilet seats, they were the least contaminated surfaces. The average desktop had 400 times more bacteria than the average toilet seat. However, general cleaners normally attend to common areas such as toilets and kitchens, but they are often instructed not to touch desks. There are no general cleaners who attend to the high touch points in office areas, but a qualified disinfection team that is trained to identify these high touch points and the usage of the disinfectants.

All diseases that are spread through direct contact with objects, including the COVID-19 are known to have a life span of several hours to days depending on the type of surface it was deposited on.

On the other hand, bacteria levels that were not sanitised increased with an average of 19-31% throughout a typical workday. In contrast, bacteria levels can be decreased by more than 99% with cleaning and sanitising at least once per day, depending on the disinfection type.

Thus, by sanitising all high touch points, it will greatly reduce the

www.envirogroup.asia | version 1.0

BUSINESS CONTINUITY BUILDING ASSESSMENT, SANITISATION, PROTECTION & CERTIFICATION GUIDANCE FOR BUILDING OPERATIONS | COVID-19 PANDEMIC

infection rate and ensure the safety and health of all workers and other persons using the common areas.

Sanitisation generally consists of two-steps process: 1. Cleaning Cleaning is the process of using detergent and water to remove visible dust, dirt, stains and odors from all surfaces, fixtures or equipment. According to the Australian Government of Health, dust, dirt and residue on a surface can inactivate many disinfectants. Thus, wiping away surface contamination first with a detergent is required prior to sanitising with a hospital grade or EPA registered disinfectant with proven effectiveness against viruses.

2. Sanitising Sanitising is the process of killing all contact surface bacteria, viruses and other microorganisms and is achieved by using an EPA registered disinfectant. After this process, the surface should have a 99.99% kill rate of microbial reduction to ensure that the surface is sanitised for safety and health assurance.

www.envirogroup.asia | version 1.0

DISINFECTION & PROTECTION

With the outbreak of Covid-19 globally, it is necessary to take measures for containment and disinfection of harmful bacteria and viruses present in the indoor environment, more importantly on high touch points.

Disinfection Pyramid

High Level Disinfection Sterilisation activities in which all microbial life, including spores and viruses are destroyed.

Medium Level Disinfection It refers to elimination of most bacteria, viruses, fungi, but not effective against spores.

Low Level Disinfection It refers to destruction of bacteria in their natural state. It is not effective against fungal spores, most viruses and not all bacteria.

ENVIRO Protect Rapid Decontamination & Surface Protection Program

Disinfectants are non-bound solutions that off-gas poisons to be effective against microbes, thus leaving nothing on the surface on total evaporation, making it ineffective for long term surface protection. Unlike BIOPROTECT, which has proven long lasting antimicrobial properties on the treated surface, even after 90 days of application.

BUSINESS CONTINUITY BUILDING ASSESSMENT, SANITISATION, PROTECTION & CERTIFICATION GUIDANCE FOR BUILDING OPERATIONS | COVID-19 PANDEMIC

EnviroClean is a surface disinfectant that is highly effective against bacteria, viruses and fungi present on the indoor surfaces, and is natural, non-toxic, biodegradable and safe to use on all surfaces.

EnviroProtect is a revolutionary anti-microbial, developed in the USA, which destroys bacteria and viruses, including Staphylococcus (MRSA), C-diff and Influenza A Virus (including H1N1 & SARS) by forming a BioProtect Anti-Microbial Shield on the treated surfaces.

BIO-PROTECT 500 is a micro-biostatic non- leaching, non-toxic antimicrobial surface protectant. This unique product is EPA registered as non-toxic, non- hazardous and USDA accepted for protective surface.

www.envirogroup.asia | version 1.0

BUSINESS CONTINUITY BUILDING ASSESSMENT, SANITISATION, PROTECTION & CERTIFICATION GUIDANCE FOR BUILDING OPERATIONS | COVID-19 PANDEMIC

In a building environment, it is important to understand the fundamental differences between surface protection and disinfection. In addition, the use of BioProtect 500 is not meant to replace current protocols. Instead, the use of BioProtect 500 will greatly enhance traditional cleaning & disinfection methods.

With most disinfectants, a ten-minute dwell time on a surface will render most microbes inactive. Unfortunately, disinfectants fall into the category of non-bound technologies. In other words, they off-gas poisons to be effective against microbes and viruses. By doing this, it in effects “give themselves up” and on total evaporation leave little if any residual benefits…dry surface = zero kill.

Here is where BioProtect 500 surface protectant stands out. Through the process of splicing Silane and Organo molecules, this combination, yields a very efficacious surface treatment. The splicing allows the best properties of a disinfectant to continue working on the surface for up to ninety (90) days. In effect, any surface treated with BioProtect 500 will have a long-term protection. Since the Mode of Action is micro-biostatic nature, it is equally effective on all surfaces. It includes both porous and non-porous surfaces. This is another benefit since most disinfectants are only approved for hard, non-porous surfaces.

With a methodical approach of cleaning and disinfecting the indoor surfaces by wiping down the surfaces which are constantly in human contact, followed by a fogging process to disinfect the complete indoor environment; The facility is disinfected and protected in a matter of hours.

THE PROCESS Before the disinfection process begins, the client has to ensure that the ventilation systems are turned off and the place is completely evacuated.

Step 1: Pre-Surface Swab & Microbial Air Sampling This process will begin with swab sampling and microbial air sampling prior to the decontamination. The samples will be sent to the accredited laboratory to determine the Total Bacterial Counts and Total Fungal Counts.

Step 2: Comprehensive Wipe Down Disinfection Our team of professionals with fully equipped PPE (Personal Protective Equipment) will begin wiping down all the areas and surfaces which are in constant human contact. Areas such as table tops, chair armrests, cabinet handles, door handles, switch boards, telephones, keyboards, mouse, printers and other accessories, shall be thoroughly wiped using micro-fiber cloth and EPA approved disinfectant.

Step 3: BioProtect Fumigation and Surface Treatment Once the surfaces have been wiped, fogging of BioProtect will be done using a fogging machine. This ensures that the disinfectant reaches all the surfaces including the walls and the floor, uniformly.

Step 4: Post-Surface Swab, Microbial Air Sampling, Rapid Swab Analysis This process will be done after the decontamination process with swab sampling and microbial air sampling. The samples will be sent to the accredited laboratory to determine the Total Bacterial Counts www.envirogroup.asia | version 1.0

BUSINESS CONTINUITY BUILDING ASSESSMENT, SANITISATION, PROTECTION & CERTIFICATION GUIDANCE FOR BUILDING OPERATIONS | COVID-19 PANDEMIC

and Total Fungal Counts. This step is critical as it provides evidence of reduced and/or eliminated microbial contaminants and verification of the program efficiency. This rapid test fills the gap between the slow classical cultivation methods and the very rapid but non-specific and inaccurate methods based on ATP technology.

Our rapid swab analysis is an EPA verified test provides rapid and reliable test results with microbiology assays used for quantifying fungi or bacteria in a wide range of sample matrices including surfaces, air, water, porous materials, particles and slurries.

The methodology has been developed in collaboration with mold remediation consultants and contractors and the Danish Building Research Institute. The technology is verified by US-EPA (Environmental Protection Agency) and was shown to have a high reproducibility.

Post the procedure, the treated area has to remain unoccupied for a minimum of 3 hours before turning the ventilation system back on.

MVAC SYSTEM: INSPECTION, CLEANING & RESTORATION According to the American Society of Heating, Refrigerating and AirConditioning Engineers (ASHRAE), “the HVAC systems in most nonmedical buildings play only a small role in infectious disease transmission, including COVID-19�. However, some infectious diseases are transmitted through inhalation of airborne infectious particles, which can be disseminated through buildings by pathways that include ventilation systems.

According to the WHO (World Health Organization), SARS-CoV-2 has been detected as an aerosol in hospitals and there is evidence that at least some strains of it remain suspended and infectious for 3 hours or more suggesting the possibility of aerosol transmission. It should be expected that coronavirus can be spread through the mechanical ventilation system, given that Legionella bacteria is first discovered to have originated and growth from poor maintenance of the MVAC system.

Owners, operators, and engineers are encouraged to collaborate with infection prevention specialists knowledgeable about transmission of infection in the community and the workplace and about strategies for prevention and risk mitigation as follows: 1. Supplying clean air to susceptible occupants 2. Containing contaminated air and/or exhausting it to the outdoors 3. Diluting the air in a space with cleaner air from outdoors and/or by filtering the air - increase the air change rate 4. Cleaning the air within the room - consider portable room air cleaners with HEPA filters 5. Controlling the indoor humidity and temperature

www.envirogroup.asia | version 1.0

BUSINESS CONTINUITY BUILDING ASSESSMENT, SANITISATION, PROTECTION & CERTIFICATION GUIDANCE FOR BUILDING OPERATIONS | COVID-19 PANDEMIC

Thus, prior to re-occupancy, it may be necessary to clean and disinfect interior occupied spaces, furnishings and the MVAC systems to reduce the risk of infection. Prevention is the key.

Here are the reasons why MVAC system should be cleaned after the MCO: 1. Most commercial building does not use HEPA filters High Efficiency Particulate Arrestance (HEPA) filters may filter air passing through them at a very fine scale to 99.97% of all particles 0.3 microns or larger. Most commercial buildings use fiberglass filters, polyester and pleated filters, which do not filter out viruses.

2. Safety considerations during maintenance In a case where viruses and all the other contaminants are filtered, the contaminants collected on the surface and insides of the MVAC system pose a biological hazard for maintenance staff. Do not risk your health and when replacing the filters or performing any of the maintenance tasks, necessary protection equipment and disinfection are recommended by health authorities.

3. Better MVAC working efficiency Clean filters and maintained systems are a must for better air cleaning efficiency. Standard filtering material is not perfect for stopping all the COVID-19 viruses, but still, some of them together with other particles will be cached and disabled.

4. Contamination of Legionnaire bacteria If the coronavirus is not detected in the MVAC system, other bacteria will thrive in those conditions. As recommended by ASHRAE, the MVAC system should be cleaned to prevent the www.envirogroup.asia | version 1.0

BUSINESS CONTINUITY BUILDING ASSESSMENT, SANITISATION, PROTECTION & CERTIFICATION GUIDANCE FOR BUILDING OPERATIONS | COVID-19 PANDEMIC

contamination and growth of Legionnaire bacteria.

Legionnaires' disease, also known as legionellosis, is a form of atypical pneumonia caused by any type of Legionella bacteria.

5. The type of MVAC system within the building Some MVAC systems such as Fan Coil Unit (FCU) systems recirculate the same existing air within the building, which may or may not contain the same airborne droplets of COVID-19 viruses. It is difficult to determine the evidence of the viruses or bacteria in the air unless cleaning and disinfection was done prior to occupancy for safety assurance.

The need of MVAC Cleaning and Restoration · Contaminated with accumulation of particulate matters · Deterioration of fiberglass, duct liner, duct board or other porous components · Performance is compromised due to contamination build-up and increased in energy cost · Discharge visible dirt or debris into an air-conditioned space. · Contaminated with construction debris or dust. · A source of unacceptable odors · As part MVAC maintenance program as specified in ASHRAE/ACCA Standard 180/

Benefits of MVAC Cleaning and Restoration · Improve Indoor Air Quality Wet portions of the MVAC systems are notorious breeding grounds for biological contaminants. Having an MVAC system re-conditioned will remove allergens like dust, dander, microbial growth and bacteria from the system and will in turn provide a healthier indoor environment to live or work. www.envirogroup.asia | version 1.0

BUSINESS CONTINUITY BUILDING ASSESSMENT, SANITISATION, PROTECTION & CERTIFICATION GUIDANCE FOR BUILDING OPERATIONS | COVID-19 PANDEMIC

· Optimize Energy Efficiency A typical duct system will lose 25% to 40% of the cooling energy put out by the system. Un-insulated, disconnected, torn, damaged or dead-end ducts are mainly responsible for that loss of energy. The cleanliness of the cooling coil system in the main MVAC system is another crucial factor to a building's energy efficiency.

· Increase System Longevity MVAC system is the most expensive mechanical system in your office and replacement can cost thousands and tremendous aggravation. Annual inspections and regular maintenance can prolong the life cycle of the MVAC system by years.

THE PROCESS Inspection Inspections shall be performed to determine the need for cleaning or any damage or error of the system. HVAC inspections shall also be performed to determine the scope of work, engineering controls, safety measures and tools and equipment necessary to perform a cleaning and restoration works.

MVAC System Cleaning & Restoration MVAC System will be cleaned by using a suitable agitation device to dislodge contaminants from the MVAC component surface then captures the contaminants with a vacuum collection device.

www.envirogroup.asia | version 1.0

BUSINESS CONTINUITY BUILDING ASSESSMENT, SANITISATION, PROTECTION & CERTIFICATION GUIDANCE FOR BUILDING OPERATIONS | COVID-19 PANDEMIC

Air Flushing Air flushing shall be performed in order to remove all contamination (dirt) from the system. This practice helps to prevent exposure of dust and ultra-fine particulates that are able to penetrate into the lungs upon reopening of the building. This activity can be done prior to sanitization or after MVAC system cleaning and decontamination.

Filter Protection In common, commercial buildings use fiberglass filters, polyester and pleated filters, which do not filter out viruses. Thus, the filter needs to be cleaned regularly and disinfected using EPA approved coating to protect the filter surface from airborne pathogens.

CARPET BIO-DECONTAMINATION

During MCO, most of the air-conditioned was switched off, all dust and particulates in the air will be settled down on the carpets over the period of time. This might affect the cleanliness of the carpet and compromise the quality of indoor air. Upon reopening buildings after MCO, carpet will be the threats to the building occupants especially for asthmatic people. Thus, carpet bio-decontamination shall be conducted to prevent the risk of sick building syndrome.

THE PROCESS

Pre-Treatment & Sanitisation Dislodge all contaminants and disinfect the carpet surface to hinder growth of all biological pollutants including bacteria, fungal, pollen and viruses.

Yes. In most cases, competent and qualified companies with registration and certification programs adhere to the proper guidelines, legislation and regulation to ensure proper work flow processes and ensure safety to the employees and the building occupants as well.

Should a building operator or facility management engage with a competent IAQ Assessor registered with the Department of Occupational Safety and Health (DOSH) to determine the risk of poor indoor air quality (IAQ) within the building?

Yes. A competent IAQ Assessor registered with DOSH is a qualified person to assess, determine, evaluate and recommend the proper next course of action so far as practicable to ensure that the risk of poor IAQ can be mitigated.

Are air purifiers recommended to improve indoor air quality?

Yes. Air purifiers are designed to filter out all contaminants in the air so as to ensure that the indoor air contaminants such as TVOCs, dusts, Environmental Tobacco Smoke (ETS), pollen and residues of any chemical disinfectants are removed and eliminated from the air.

This will improve overall indoor air quality, comfortability and wellness of the building. www.envirogroup.asia | version 1.0
