IDENTIFICATION:
CAS:
74-98-6
DOT ID:
UN1978;
UN1075 (Liquefied petroleum gas)
Hazard Class or Division:
2.1 (FLAMMABLE GAS)
ERG Guide:
115
Formula:
C3H8
RTECS No:
TX2275000
Properties:
Extremely
flammable colorless liquefied gas; may be a liquid under pressure or
refrigeration. Faint petroleum-like odor; may contain additives whose odor will
warn of leaking gas; has been described as a "skunk" odor. Slightly
soluble; liquid floats and "boils" on water. Flammable visible vapor
cloud is produced. Gas is heavier than air; will collect in low areas.
Uses:
Fuel
for welding and cutting operations; component of (LPG) liquid petroleum gas;
refrigerant.
HEALTH & SAFETY INFORMATION
• IDLH:
2100
ppm [10% LEL]
• Odor threshold:
9,150–36,600 mg/m3
•
OSHA Table Z-1 Air Contaminant
•
High levels of gas can cause asphyxiation if atmosphere does not contain enough
oxygen; dizziness, drowsiness, loss of consciousness, and possible death. Skin
contact with liquid may cause frostbite.
Exposure Limits:
•
ACGIH TLV: 2500 ppm TWA
•
OSHA PEL/NIOSH REL: 1000 ppm/1800 mg/m3 TWA

respirator) SCBAF (any self-contained breathing apparatus with a full

Emergency
or Planned Entry into Unknown Concentrations or IDLH Conditions
SCBAF:PD,PP (any self-contained breathing
apparatus that has a full facepiece and is operated in a pressure-demand or
other positivepressure mode) SAF:PD,PP:ASCBA (any suppliedair respirator that
has a full facepiece and is operated in a pressure-demand or other
positive-pressure mode in combination with an auxiliary self-contained
breathing apparatus operated in a pressure-demand or other positive-pressure
mode).
Escape:
SCBAE
(any appropriate escape-type, self-contained breathing apparatus).
Reactivity:
Forms
explosive gas mixture with air. Or on contact with chlorine dioxide. Contact
with strong oxidizers may cause fire and explosions. The liquid attacks some
plastics, rubber, and coatings. May accumulate static electrical charges and
may cause ignition of its vapors.
FIRE INFORMATION:
Gas may travel long distances to ignition sources and flash
back. Gas in confined areas or containers may explode in fire.

FIRST AID:
Move
victim to fresh air. Call emergency medical care. Apply artificial respiration
if victim is not breathing. Administer oxygen if breathing is difficult. Remove
and isolate contaminated clothing and shoes. Clothing frozen to the skin should
be thawed before being removed. In case of contact with liquefied gas, thaw frosted
parts with lukewarm water. Keep victim warm and quiet. Ensure that medical
personnel are aware of the material(s) involved, and take precautions to
protect themselves.
