Topic 2 PPE-clothing and equipment used to minimise injury from a variety of hazards
Body protection
Lab coats
Protects skin from
hazardous spills, prevent contamination
of clothes
Flame-resistant
lab coats: protect user, in places with flammable chemicals
Used in
low-hazard
settings
Surgical gown
Protect user from
infectious material,
prevent contamination beyond workplace
Coveralls
Offer
higher level of protection,
replace clothing and protects user from biological, chemical, thermal hazards etc.
Full body suit(Positive pressure suit)
Used in BSL-4 labs
Create a full body barrier, prevent contamination to wearer
When punctured,
positive air pressure forces air out instead of letting air in
Extensive training required
Filtered air supplied to interior of suit
Eye and face protection
Face shield
Highest level of protection, protects eyes, face and neck from chemical splashes, sprays,flying particles and fragments
Transparent shield that stretches across width of face
Safety glasses
Offer UV protection and anti-fog capabilities
No seal around eyes, can only
be used in low-hazard settings
Safety goggles
Forms a seal
around the eyes and surrounding areas, which protects it from hazardous chemical splashes, sprays
Offers a higher level of protection than safety glasses
Head protection
Helmets
Minimise injury from impact of falling objects onto head, skull, brain.
Foot protection
Waterproof safety boots
Prevent risk of
slip and fall
in wet conditions
Chemical resistant boots
Protect foot from
chemical splashes
of corrosive acids
Disposable covers
barrier against infectious materials
Prevent spread of contaminants that come in contact with shoe
Heat resistant boots
Protect foot from
high temperatures
Steel-toed/Safety shoes/boots
prevent injuries from
impacts, cuts, compressions
Ear protection
Ear plugs
Ear muffs
Function: To protect user from overexposure to excessively noisy environment and reduce risk of hearing loss
Respiratory protection
Filtering respirators
Protect users from inhaling infectious microorganisms, dusts,fumes and mists
No protection against harmful
gases and vapours
Half-face and full-face respirators
Provide respiratory protection against infectious agents, particles, fumes
, vapours and gases
Have replaceable
filters that purifies
breathing air of user
Covers entire face
Powered air purifying respirators
Forces air through filter cartridges and filters air that enters breathing zone
Decreases likelihood of infection transmission than filtering, half-face and full-face respirators
Protects user from infectious agents, particles, vapours, gases and fumes
Factors to consider when using repirators
Hazard assessment done to
determine correct type of respirator
used
Tight-fitting respirators need to be
individually fit-tested
before use
Annual fit test
Training
required to use respirator
Hand protection
Thermal gloves
Insulated gloves
that protect user's hands from
extreme hot and cold temp
Puncture-resistant gloves
protect user from
cuts, punctures from contaminated sharps and needles or animal bites
Disposable gloves
prevent spread of infection
, protect against direct contact with biological hazard
Chemical resistant gloves
Protect hands from chemical splashes from corrosive, toxic chemicals
