Question

george is working on an asbestos removal job and is wondering if he needs a respirator. in which of the following situations would he need one?
a) all class ii and iii jobs performed using wet methods.
b) all class iv jobs.
c) any class of job which is to be performed in a low-ventilation area.
d) a class iii job where thermal system insulation will be disturbed.

Explanation:

Low-ventilation areas trap asbestos fibers, increasing inhalation risk regardless of job class. Wet methods for Class II/III reduce fiber release, Class IV jobs involve minimal asbestos disturbance, and not all Class III insulation work inherently requires a respirator without additional risk factors like poor ventilation. Only low-ventilation conditions universally necessitate a respirator to avoid fiber exposure.

Answer:

C. Any class of job which is to be performed in a low-ventilation area.
