REQUIRED PERSONAL
PROTECTION
• GOGGLES
• APRONS
• PUT ON BEFORE GETTING ANY
CHEMICALS OR EQUIPMENT

STRONG SUBSTANCE SPILLED
ON A PERSON

7
FIRE BLANKET
• USED FOR CLOTHING OR HAIR
ON FIRE
• WRAP AROUND PERSON AND
OVER THEIR HEAD
8
BURNING HAIR

FIRE EXTINGUISHER
•
•
•
•
•
PASS
PULL THE PIN
AIM AT THE BASE OF FIRE
SQUEEZE THE TRIGGER
SWEEP AROUND THE BASE OF
THE FIRE
10
WASTE DISPOSAL
• FOLLOW DIRECTIONS
CAREFULLY
• BROKEN GLASS GOES INTO
THE PROPER CONTAINER
11
HANDLING CHEMICALS
• DON’T TOUCH UNLESS YOU
ASK!
12
OBSERVING CHEMICALS
• KEEP A REASONABLE DISTANCE
BETWEEN FACE AND
SUBSTANCE
• WAFT FOR ODOR
13
HANDLING GLASSWARE
• CHECK FOR CHIPS OR CRACKS
(DO NOT use chipped or cracked glass!)
• USE INSULATED GLOVES IF HOT
• SIT HOT GLASS ON INSULATING PAD
• CLEAN UP BROKEN GLASS WITH
DUSTPAN AND BRUSH, NOT
FINGERS
14
FIRST AID
• CHEMICAL ON SKIN – WASH
• CHEMICAL IN MOUTH – SPIT
AND FLUSH
15
HAZARDS
• HEALTH
• FLAMMABILITY
• REACTIVITY
16
TOXIN
• SUBSTANCE THAT CAN HURT
YOU IN SMALL AMOUNTS
17
TOXICITY
• DETERMINED BY HOW MUCH
(DOSE)
• ALSO AFFECTED BY TIME OF
EXPOSURE
18
PERSONAL EXPOSURE
•
•
•
•
BREATHING
EATING / DRINKING
THROUGH SKIN
THROUGH CUT
19
RATING SCALES
• QUICK ID OF HAZARD LEVEL
• 0 IS NO HAZARD
• 4 IS THE WORST HAZARD
20
HEALTH 4
• VERY SHORT EXPOSURE
COULD CAUSE DEATH OR
MAJOR INJURY EVEN WITH
QUICK MEDICAL TREATMENT
• EXAMPLES –HYDROGEN
CYANIDE, CHLORINE, NICOTINE
21
HEALTH 3
• SHORT EXPOSURE COULD
CAUSE SERIOUS INJURY EVEN
WITH QUICK MEDICAL
TREATMENT
• EXAMPLES –PHENOL,
POTASSIUM, CARBON
MONOXIDE
22
HEALTH 2
• LONG EXPOSURE COULD
CAUSE SERIOUS INJURY,
SHORT EXPOSURE CAN BE
MEDICALLY TREATED
• EXAMPLES –CAFFEINE,
NAPHTHALENE
23
HEALTH 1
• EXPOSURE MAY CAUSE
IRRITATION OR MINOR INJURY
• EXAMPES – ACETONE,
GRAPHITE
24
HEALTH 0
• NO SIGNIFICANT HAZARD
• EXAMPLES – PARAFFIN,
DISTILLED WATER, CHARCOAL
25
FLAMMABLE VS.
COMBUSTIBLE
• COMBUSTIBLE – CAN BURN
• FLAMMABLE – EASILY IGNITED
AND BURNS READILY
26
FLAMMABILITY 4
• HIGHLY FLAMMABLE
• EXAMPLES – BUTANE, NATURAL
GAS, PROPANE, METHANE
27
FLAMMABILITY 3
• CAN BURN UNDER MOST
CONDITIONS
• EXAMPLES – ACETONE, ETHYL
ALCOHOL
28
FLAMMABILITY 2
• MUST BE HEATED MODERATELY
TO BURN
• EXAMPLES – DIESEL FUEL,
MINERAL SPIRITS
29
FLAMMABILITY 1
• MUST BE HEATED A LOT TO
BURN
• EXAMPLES – MINERAL OIL,
LUBRICATING OIL
30
FLAMMABILITY 0
• CANNOT BURN (CAN BE USED
TO EXTINGUISH FIRES)
• EXAMPLES – WATER, CARBON
DIOXIDE, HALON
31
REACTIVITY
• HOW EASILY A SUBSTANCE
REACTS AND EXPLODES
• MAY OR MAY NOT INVOLVE
OTHER SUBSTANCES
32
REACTIVITY 4
• EASILY EXPLODES
• EXAMPLES – NITROGLYCERINE
33
REACTIVITY 3
•
•
•
•
CAN EXPLODE IF SHOCKED
EXAMPLES: TNT, DYNAMITE
REACT VIOLENTLY WITH WATER
EXAMPLES: POTASSIUM,
SODIUM
34
REACTIVITY 2
• BECOME REACTIVE BUT DO
NOT EXPLODE
• REACT SIGNIFICANTLY WITH
WATER
• EXAMPLES – LITHIUM, CALCIUM
CARBIDE
35
REACTIVITY 1
• BECOME REACTIVE AT HIGH
TEMPERATURES BUT DO NOT
EXPLODE
• REACT MILDLY WITH WATER
• EXAMPLES – SODIUM
HYPOCHLORITE, CALCIUM
OXIDE
36
REACTIVITY 0
• DO NOT REACT
• EXAMPLES – TABLE SALT, SAND
(SiO2)
