Elimination
“equipment worn to minimize exposure to hazards that
cause serious workplace injuries and illnesses”
PPE
“specialized clothing or equipment worn by an employee
for protection against infectious materials” (OSHA)
PPE
Appropriate PPE should be based on the?
▶ 1. risk of exposure (e.g. type of activity)
▶ 2. transmission dynamics of the pathogen
▶(e.g. contact, droplet or aerosol)
Modes of COVID-19 transmission
▶ 1. mainly through respiratory droplets and contact
▶ 2. airborne transmission is possible during aerosol-generating procedures (AGPs)
suspension of tiny particles or droplets in the air, such as
dusts, mists, or fumes
Aerosols
Limit opportunities for “touch contamination”
Gloves
▶ should be fluid-resistant to splash or spray of bodily fluids
▶ provides protection against droplet transmission
▶ wearer can still breathe unfiltered air around the edge of the
mask
Surgical masks (Face masks)
▶ should be fluid-resistant to splash or spray of bodily fluids
▶ provides protection against droplet transmission
▶ wearer can still breathe unfiltered air around the edge of the
mask
