Which work practice is allowed when handling lead hazards?

The selection of closed-system mechanical removal as the appropriate work practice when handling lead hazards is grounded in safety protocols designed to minimize exposure to lead dust and particles. This method employs specialized equipment that contains the lead material and prevents contamination of the surrounding environment. The mechanical approach ensures that any lead debris is contained within a controlled setting, thus reducing the risk of inhaling lead particles or having them settle onto surfaces around the work area.

By contrast, other methods listed are significantly more hazardous. For instance, using heat guns above 1100 degrees can create fumes and release lead particles into the air, posing serious health risks. Abrasive sanding without HEPA collection generates a large amount of lead dust, which can quickly become airborne and widely dispersed. Open air blasting not only creates visible lead contamination but also carries the risk of inhalation of lead-laden particles by workers and bystanders alike. These practices can increase lead exposure and are not permissible under guidelines for safely managing lead hazards.

Using closed-system mechanical removal is thus the safest and most responsible work practice in this context, ensuring that lead hazards are managed effectively while protecting the health of both workers and the general public.
