Worker Protection & PPE Flashcards

How often must respirator cartridges used during lead renovation work be replaced?

Answer: According to the manufacturer's schedule or when breathing resistance increases

Respirator cartridges must be changed per the manufacturer's change-out schedule or when the worker notices increased breathing resistance.

Why is a dust mask (surgical mask or N-95) alone considered insufficient for lead renovation work?

Answer: It does not filter fine lead dust particles to the required level and lacks a proper face seal

Standard dust masks and surgical masks lack the tight face seal and high filtration efficiency needed to adequately protect against fine lead dust particles.

What is the purpose of a decontamination area (anteroom) at a lead renovation site?

Answer: To provide a transition zone where workers remove contaminated PPE before entering clean areas

The decontamination area or anteroom is a buffer zone where workers remove and bag contaminated PPE before exiting the lead work area.
