Level 1
What level of PPE involves wearing a surgical mask, goggles or face shield, gown, and gloves
Level 2
What level of PPE involves wearing an N95 mask, goggles or face shield, gloves, surgical cap, scrub suits, gowns or coveralls, and shoe covers

Level 4
T or F: Appropriate PPE should be based on the risk of exposure and transmission dynamics of the pathogen
True
These refer to the suspension of tiny particles in the air such as dusts, mists, or fumes
Aerosols
T or F: Gloves must work from dirty to clean
False (clean to dirty)
T or F: Gloves are worn during blood collection and specimen-handling
True
T or F: Gloves limit the opportunities for “respiratory contamination”
False (touch contamination)
What type of glove is this?
→ no latex and powder-free
→ most puncture-resistant
→ high level of touch sensitivity
→ molds to the user’s hands for a good fit
→ good for wearing for an extended amount of time and has a long shelf life
→ works well for high-risk situations
→ resists many chemicals
Nitrile
What type of glove is this?
→ fits like a second skin
→ high level of touch sensitivity
→ good for wearing for an extended amount of time
→ works well for high-risk situations
→ are cost effective
→ lightly powdered for easy donning
→ very elastic and strong
Latex
What type of glove is this?
→ contains no latex
→ has a looser fit
→ good for short-term, low-risk tasks
→ most economic option
→ has anti-static properties
→ best used for non-hazardous materials
→ lightly powdered for easy donning
Vinyl
This type of glove is not environment-friendly and garners a higher cost
Nitrile
This type of glove is allergy-inducing, has a short shelf-life, and difficult to don and doff
Latex
This type of glove is often wrinkled and saggy, has low dexterity, and low sensitivity
Vinyl
What is this type of mask?
→ level of protection is uncertain
→ depends on the cloth and the fit
→ NOT used in healthcare settings
Fabric mask
What type of mask is this?
→ aka face masks
→ should be fluid-resistant to splash or spray of bodily fluids
→ wearer can still breathe unfiltered air at the sides of the mask
Surgical mask
T or F: The outer layer of the mask is not fluid-repellant
False (should be fluid-repelling)
T or F: The middle layer of the mask should be high filtering
True
T or F: The inner layer of the mask should be fluid absorbing
Fale (moisture-absorbing)
FFPR stands for?
Filtering face piece respirator
What respirator is this?
→ has a tight seal around the mask so that all air passes through a filter
→ can be used in high-risk settings and procedures
Filtering face piece respirator (FFPR)
An N label refers to what type of oil resistance?
Not resistant
An R label refers to what type of oil resistance?
Resistant for up to 8 hours
A P label refers to what type of oil resistance?
Oil-proof
What type of mask is this?
→ removes 95% of .3+ micron-particles
→ contains a valve (optional) which reduces breathing resistance during exhalation
→ material is a tough yet flexible non-woven polypropylene fiber
N95 mask
T or F: N95 masks are aka FFP3
False (FFP2)
An FFP2 mask can filter what percentage of particles bigger than 0.3 micrometers?
94-95%
An FFP3 mask can filter what percentage of particles bigger than 0.3 micrometers?
99%
PAPR stands for?
Powered air purifying respirator
This is an alternative to N95 respirators; it filters out contaminants in the air by using a battery-powered fan to force air through a filter cartridge or canister to a tight-fitting face piece or loose hood
Powered air purifying respirator (PAPR)
What type of protective clothing is easier to don and doff?
Long-sleeved water-resistant gowns
T or F: If gown is too small, use 3 gowns
False (2 only; gown 1 ties to the front while gown 2 ties to the back)
This type of protective clothing:
→ covers the whole body including the back and lower legs
→ difficult to doff
→ generates more heat stress
→ leads to discomfort, fatigue, and dehydration
Coveralls
T or F: The gown must cover the ends of the gloves over the wrist
