What is the HVAC procedure at the start of an asbestos abatement project?

• A. The air vents within the area are sealed with plastic
• B. The system is left running during the procedure
• C. The control box is left unlocked for maintenance access
• D. The area is fully ventilated to reduce dust

Answer: (A)

At the start of an asbestos abatement project, sealing the air vents within the area with plastic is a critical procedure. This step helps to prevent the spread of asbestos fibers to other parts of the building and minimizes contamination during removal. The sealing process creates a containment area that isolates the work zone from the rest of the environment, ensuring safety for both the workers and building occupants. Other options, such as leaving the HVAC system running or keeping the control box unlocked, would increase the risk of asbestos being circulated throughout the building, counteracting the purpose of containment. Additionally, fully ventilating the area could disperse airborne asbestos fibers, which is not a safe or effective strategy during an abatement process. Therefore, sealing the vents is an essential precaution to maintain a controlled and safe environment for asbestos removal.
