IDENTIFICATION:
CAS:
115-07-1
DOT ID:
UN1077;
UN1075 (Liquefied petroleum gas)
Hazard Class or Division:
2.1 (FLAMMABLE GAS)
ERG Guide:
115
Formula:
C3H6
RTECS No:
UD0890000
Properties:
Extremely
flammable colorless gas. Faint petroleum odor. Shipped and stored as a
liquefied compressed gas. Floats and "boils" on water surface;
insoluble in water. Gas is heavier than air; will collect in low areas.
Uses:
As
fuel; as aerosol propellant, and component; making other chemicals.
HEALTH & SAFETY INFORMATION
• IARC:
Group
3, not classifiable as to carcinogenicity to humans; no human data; no animal
data
•
ACGIH simple asphyxiant. On loss of containment, this gas can cause suffocation
by lowering the oxygen content of the air in confined areas. Moderate levels of
gas may affect the central nervous system causing drowsiness and loss of
consciousness. Rapid evaporation of the liquid may cause frostbite.
Respirator:
At
any concentrations above the NIOSH REL, or where there is no REL, at any
detectable concentration:
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:
GMFOV
[any airpurifying, full-facepiece respirator (gas mask) with a chin-style,
front- or back-mounted organic vapor canister] SCBAE (any appropriate
escape-type, selfcontained breathing apparatus).
Reactivity:
Forms
explosive mixture with air. Able to form dangerous peroxides; may polymerize.
Contact with strong oxidizers or strong acids may cause fire and explosions.
May accumulate electrical charges and may cause ignition of its vapors.
FIRE INFORMATION:
Gas is heavier than air; may ravel to source of ignition and
flash back. Gas in confined areas or containers may explode in fire. If
material or contaminated runoff enters waterways, notify downstream users of
potentially contaminated water.

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. Keep victim
under observation. Ensure that medical personnel are aware of the material(s)
involved, and take precautions to protect themselves.
