With our COVID-19 trainings for businesses, we've trained and certified our companies for compliance with OSHA, CDC and EPA guidelines. For more information on our COVID-19 trainings for businesses.
Contractors should always adhere to OSHA regulations to ensure worker protection and safety. According to OSHA's hierarchy of Controls, Elimination/Substitution of hazards followed by Engineering Controls, Administrative Controls and then PPE. When we clean and apply disinfectants, we are essentially eliminating the hazard (coronavirus). However, all hazard controls are important and will need to be evaluated at each property.
In some situations, certain engineering controls may need to be established for prevention of cross contamination. Containment with decontamination chambers, critical barriers and negative pressure, HEPA filtration are common examples of engineering controls. The purpose of engineering controls is to isolate areas of the building to protect unaffected people and/or previously cleaned or sensitive areas. This may include setting up a staging or decontamination area for workers to doff Personal Protective Equipment (PPE). The contractor understands the concept of negative pressure and contaminant pathways during this project. Containments will be established similar to other environmental projects (i.e. mold, asbestos, lead, etc.) using polyethylene sheeting and negative pressure equipment with HEPA filtration. Negative pressure be will attempted to maintain at a minimum of -0.02" WC or -5 Pascals with a minimum of 4 Air Changes per Hour (ACH). Some situations, negative pressure containments may not be needed or necessary and therefore HEPA scrubbers are recommended.
Administrative controls need to be implemented not only for workers providing these services but likely for internal staff and employees of the subject site. This may include the change or modification to routine cleaning and janitorial services and overall improvements in cleanliness and hygiene policies & procedures.
All personnel performing this work will be properly trained and will be in compliance with local, state and federal regulations, including but not limited to OSHA, CDC & EPA. All containment barriers, PPE (suits, gloves, booties, etc.), waste bags, and spent cleaning items will be placed in heavy duty trash bags. Bags will be gooseneck sealed and the outside of the bags wiped down with a disinfectant and disposed of in accordance with regulations. All restoration equipment (HEPA equipment) will be decontaminated.
