POTENTIAL CAUSES OF FIRE AND EXPLOSION:
A.
CHEMICAL REACTIONS
B.
IGNITION OF EXPLOSIVE OR FLAMMABLE CHEMICALS
C.
IGNITION OF MATERIALS DUE TO OXYGEN ENRICHMENT ( > 23.5% )
D.
AGITATION OF SHOCK OR FRICTION SENSITIVE COMPOUNDS
E.
SUDDEN RELEASE OF MATERIALS UNDER PRESSURE
Explosions and fires may arise spontaneously. However, more commonly, they
result from site activities such as:
A.
MOVING DRUMS
B.
ACCIDENTALLY MIXING INCOMPATIBLE CHEMICALS

SELF-CONTAINED BREATHING APPARATUS
A Self-Contained Breathing Apparatus (SCBA) usually consists of a face piece
connected by a hose and a regulator to an air source carried by the wearer.

SUPPLIED-AIR RESPIRATORS
Supplied-Air Respirators (SAR) (also known as airline respirators) supply breathing
air, never oxygen, to a face piece via a supply line from a source located some
distance away and connected to the user by an air line hose.

CHEMICAL PROTECTIVE CLOTHING
IV. LEVELS OF PROTECTION:
The individual components of clothing and equipment must be assembled into a full
protective ensemble that both protects the worker from the site specific hazards and
minimizes the hazards and drawbacks of the PPE ensemble itself.
LEVEL
RESPIRATOR
C.P.C.
PROTECTION
A
Pressure-demand
full-face piece SCBA
Pressure-demand
supplied-air respirator
with escape SCBA.
Fully-encapsulating,
chemical-resistant
suit. Will give vapor
protection.
The highest available
level of respiratory, skin,
and eye protection.
B
Pressure-demand
full-face piece SCBA
Pressure-demand
supplied-air respirator
with escape SCBA.
Chemical-resistant
clothing (overalls &
long-sleeved jackets;
disposable chemical
resistant one piece suit).
The same level of
respiratory protection
but less skin protection
than level A.
C
Full-facepiece,
air-purifying,
canister-equipped
respirator.
Chemical-resistant
clothing (overalls &
long-sleeved jackets;
disposable chemical
resistant one piece suit).
The same level of skin
protection as level B,
but a lower level of
respiratory protection.
D
No respiratory
protection is
provided.
Coveralls, safety boots/
shoes, safety glasses
or chemical splash
goggles, hard hat.
No respiratory protection.
Minimal skin protection.
