Question

The measures required to control asbestos fibers in the air during high-risk activities include all these procedures except?

1) Drench all ACM with water
2) Apply a constant, light spray of water near workers
3) Clean exposed surfaces with damp wipes and cover with sealant
4) Keep work area air pressure higher than surrounding pressures

Answer 1

The measure not used to control asbestos fibers in the air during high-risk activities is keeping work area air pressure higher than surrounding pressures; this could spread asbestos fibers rather than contain them.

Step-by-step explanation:

The measures required to control asbestos fibers in the air during high-risk activities include all the following procedures except keeping work area air pressure higher than surrounding pressures. The known methods for controlling asbestos exposure during activities that could release fibers into the air include:

1. Drenching all asbestos-containing material (ACM) with water
2. Applying a constant, light spray of water near workers
3. Cleaning exposed surfaces with damp wipes and covering them with sealant

However, keeping the work area air pressure higher than surrounding pressures is not a recommended practice, as it could potentially spread asbestos fibers to surrounding areas instead of containing them. The control measures aim to minimize the release and inhalation of asbestos fibers to prevent
