3 - Hazards Identification
SPECIAL INDICATION OF HAZARDS TO HUMANS AND THE ENVIRONMENT
Flammable. Toxic by inhalation. Causes burns. Very toxic to
aquatic organisms.
4 - First Aid Measures
AFTER INHALATION
If inhaled, remove to fresh air. If not breathing give
artificial respiration. If breathing is difficult, give oxygen.
AFTER SKIN CONTACT
In case of contact, immediately wash skin with soap and copious
amounts of water.
AFTER EYE CONTACT
Contamination of the eyes should be treated by immediate and
prolonged irrigation with copious amounts of water. Assure
adequate flushing of the eyes by separating the eyelids with
fingers.
AFTER INGESTION
If swallowed, wash out mouth with water provided person is
conscious. Call a physician.
5 - Fire Fighting Measures
EXTINGUISHING MEDIA
Suitable: Use water spray or fog nozzle to keep cylinder cool.
Move cylinder away from fire if there is no risk.
SPECIAL RISKS
Specific Hazard(s): Vapor may travel considerable distance to
source of ignition and flash back. Emits toxic fumes under fire
conditions. Flammable gas.
Explosion Hazards: May form explosive mixtures with air
Container explosion may occur under fire conditions.
SPECIAL PROTECTIVE EQUIPMENT FOR FIREFIGHTERS
Wear self-contained breathing apparatus and protective clothing
to prevent contact with skin and eyes.
SPECIFIC METHOD(S) OF FIRE FIGHTING
Do not extinguish burning gas if flow cannot be shut off
immediately. Use water spray or fog nozzle to keep cylinder
cool. Move cylinder away from fire if there is no risk.
6 - Accidental Release Measures
PERSONAL PRECAUTION PROCEDURES TO BE FOLLOWED IN CASE OF LEAK OR SPILL
Evacuate area and keep personnel upwind. Shut off leak if there
is no risk. Shut off all sources of ignition.
PROCEDURE(S) OF PERSONAL PRECAUTION(S)
Wear self-contained breathing apparatus, rubber boots, and heavy
rubber gloves.
METHODS FOR CLEANING UP
Ventilate area and wash spill site after material pickup is
complete.
7 - Handling and Storage
HANDLING
Directions for Safe Handling: Do not breathe gas. Do not get in
eyes, on skin, on clothing. Avoid prolonged or repeated exposure.
STORAGE
Conditions of Storage: Keep tightly closed. Use with equipment
rated for cylinder pressure, and of compatible materials of
construction. Close valve when not in use and when empty. Make
sure cylinder is properly secured when in use or stored Cylinder
temperature should not exceed 125藲F (52藲C).
SPECIAL REQUIREMENTS: Contents under pressure.
8 - Exposure Controls / Personal Protection
ENGINEERING CONTROLS
Safety shower and eye bath. Warning: suck-back into cylinder may
cause rupture. Use back-flow-preventive device in piping. Use only
in a chemical fume hood.
GENERAL HYGIENE MEASURES
