True or False: Employees should always perform a positive/negative seal check when donning a respirator.

Performing a positive/negative seal check when donning a respirator is essential for ensuring that the respirator is fitting correctly and providing the intended level of protection. A positive/negative seal check helps confirm that there are no air leaks between the mask and the face, which would allow hazardous substances to enter the breathing space. This practice is crucial in all situations where respirators are used, as a proper seal is necessary regardless of the type of respirator or the materials being handled. By conducting this check, employees are taking proactive measures to enhance their safety and minimize their risk of exposure to harmful airborne contaminants. This adherence to safety protocols is key in maintaining compliance with occupational health and safety regulations, especially in lead abatement scenarios where exposure risks are significant.
