OSHA Can Cite Employers for
Failure to:
Provide affected employees who provide and use
their own respirators with the notice
Provide training to ensure that each employee
wearing a respirator receives training prior to first
use and if they change the type of respirator
Ensure employees are conducting user seal checks
Supervise reuse of respirators
Require employees to discontinue use of respirators
when employees report or experience signs and
symptoms that are related to their ability to use a
respirator
12/02/2021
14
Facemasks
Loose-fitting
- don't provide complete protection
Create
physical barrier
between mouth and nose of
wearer and potential contaminants
Help reduce exposure of wearer’s saliva and
respiratory secretions to others
Help
block large-particle
droplets, splashes, sprays
or splatter that may contain viruses and bacteria
Do not filter very small particles
transmitted by
coughs, sneezes or certain medical procedures

Air-Purifying Respirator (APR)
Tight-fitting respirator with a filter, cartridge, or
canister that removes specific air contaminants
by passing ambient air through the air-purifying
element.
