63
NFPA Hazard Identification

• National
• Fire
• Protection
• Agency

64
Numbers mean??

• 0least severe hazard
• 4most severe hazard

65
Flammability (RED)

• Susceptibility of Material to Burning.

66
Flammability

• 0Material will not burn (water)
• 1--Material must be pre-heated before ignition
  can occur. (corn oil)
• 2--Material must be moderately heated or exposed
  to relatively high ambient temperature before
  ignition can occur. (diesel fuel)
• 3--Liquids and solids that can be ignited under
  almost all ambient temperature conditions.
  (gasoline)4
• 4--Materials that will rapidly or completely
  vaporize at atmospheric pressure and normal
  ambient temperature, or that are readily
  dispersed in air and that will burn
  readily.(propane gas)

67
Reactivity or instability (yellow)

• Susceptibility of Material to Reacting.

68
Reactivity

• 0--Material that in itself is normally stable,
  even under fire exposure conditions, and is not
  reactive with water.Example liquid nitrogen
• 1--Material that in itself is normally stable,
  but which can become unstable at elevated
  temperatures and pressures.Example phosphorus
  (red or white)
• 2--Material that readily undergoes violent
  chemical change at elevated temperatures and
  pressures or which reacts violently with water or
  which may form explosive mixtures with
  water.Example calcium metal
• 3--Material that in itself is capable of
  detonation or explosive decomposition or reaction
  but requires a strong initiating source or which
  must be heated under confinement before
  initiation or which reacts explosively with
  water.Example fluorine gas
• 4--Material that in itself is readily capable of
  detonation or of explosive decomposition or
  reaction at normal temperatures and
  pressures.Example trinitrotoluene (TNT)

69
Health Hazard (Blue)

• Type of Possible Injury.

70
Health Hazard

• 0--Material that on exposure under fire
  conditions would offer no hazard beyond that of
  ordinary combustible material.Example peanut oil
• 1--Material that on exposure would cause
  irritation but only minor residual
  injury.Example turpentine
• 2--Material that on intense or continued but not
  chronic exposure could cause temporary
  incapacitation or possible residual
  injury.Example ammonia gas
• 3--Material that on short exposure could cause
  serious temporary or residual injury.Example
  chlorine gas
• 4--Material that on very short exposure could
  cause death or major residual injury.Example
  hydrogen cyanide

71
Special Precautions(white)

• W (with line)Material shows unusual reactivity
  with water (i.e. don't put water on it).Example
  magnesium metal
• OX--Material possesses oxidizing
  properties.Example ammonium nitrate (fertilizer
  used in Oklahoma City bomb

72
Special Precations

• ACID--Material is an acid.
• ALK--Material is a base (alkaline).
• COR--Material is corrosive.

Electricity water dont mix.

• Hands must be completely dry
• before touching an electrical switch,
• plug, or outlet.

84
Dont use dirty, chipped or cracked glassware

• .

85
Report damage

• Report damaged electrical equipment
• immediately. Look for things such as frayed
  cords, exposed wires, and loose
• connections. Do not use damaged electrical
  equipment.

86
ASK!!

• If you do not understand how to use a piece of
  equipment, ask the instructor for help.

87
NO Hot in cold

• Do not immerse hot glassware in cold
• water it may shatter.

88
Heating Substances
89
Hair, clothing, and hands away from flame.
90

• Do not put any substance into the flame unless
• specificallyinstructed to do so.

91
Never reach over anexposed flame.
92
Light burners only as instructed by the
teacher.
93
Never leave a lit burner unattended.
94
Never leave anything that is being heated or is
visibly reacting unattended
95
Always turn the burner or hot plate off when not
in use
96
Dont look into a container being heated
97

• Point the open end of
• a test tube being heated away from
• yourself or anyone else.

98
Use tongs if necessary

• Heated metals and glass remain very
• hot for a long time. They should be set
• aside to cool and picked up with caution.

99
Dont burn the lab bench

• Do not place hot apparatus directly on
• the laboratory desk. Always use an insulating
• pad. Allow plenty of time for hot
• apparatus to cool before touching it.

100
Hot and cold glass look alike

• When bending glass, allow time for the
• glass to cool before further handling. Hot
• and cold glass have the same visual
• appearance. Determine if an object is hot
• by bringing the back of your hand close
• to it prior to grasping it.
