Composition comments
All concentrations are in percent by weight unless ingredient is a gas. Gas concentrations are in
percent by volume.
4. First-aid measures
Inhalation
Move to fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration.
Call a physician or poison control center immediately.
Skin contact
Remove contaminated clothing immediately and wash skin with soap and water. Get medical
attention if irritation develops and persists. If frostbite occurs, immerse involved area in warm water
(between 100 F/38 C and 110 F/43 C, not exceeding 112 F/44 C). Keep immersed for 20 to 40
minutes. Seek medical assistance.
Eye contact
Immediately flush eyes with plenty of water for at least 15 minutes. Remove contact lenses, if
present and easy to do. Continue rinsing. Get medical attention immediately.
Ingestion
Ingestion is not a typical route of exposure for gases or liquefied gases.
Most important
symptoms/effects, acute and
delayed
Exposure to rapidly expanding gas or vaporizing liquid may cause frostbite ("cold burn"). Very high
exposure can cause suffocation from lack of oxygen. May cause drowsiness or dizziness.
Indication of immediate
medical attention and special
treatment needed
Exposure may aggravate pre-existing respiratory disorders. Treat symptomatically.
General information
Ensure that medical personnel are aware of the material(s) involved, and take precautions to
protect themselves.
5. Fire-fighting measures
Suitable extinguishing media
Dry chemical, CO2, water spray, fog, or foam.
Unsuitable extinguishing
media
None known.
Specific hazards arising from
the chemical
Selection of respiratory protection for firefighting: follow the general fire precautions indicated in
the workplace.
Special protective equipment
and precautions for firefighters
Self-contained breathing apparatus and full protective clothing must be worn in case of fire.
Fire-fighting
equipment/instructions
Move container from fire area if it can be done without risk.
Do not extinguish fires unless gas flow can be stopped safely; explosive re-ignition may occur.
Promptly isolate the scene by removing all persons from the vicinity of the incident. No action shall
be taken involving any personal risk or without suitable training. For fires involving this material,
do not enter any enclosed or confined fire space without proper protective equipment, including
self-contained breathing apparatus. Stop flow of material. Use water to keep fire exposed
containers cool and to protect personnel effecting shutoff. If a leak or spill has not ignited, use
water spray to disperse the vapors and to protect personnel attempting to stop leak. Prevent
runoff from fire control or dilution from entering streams, sewers or drinking water supply.
General fire hazards
Extremely flammable gas.
6. Accidental release measures
Personal precautions,
protective equipment and
emergency procedures
Evacuate the area promptly. No action shall be taken involving any personal risk or without
suitable training. Keep unnecessary personnel away.
Ensure adequate ventilation. In case of inadequate ventilation, use respiratory protection. Wear
appropriate personal protective equipment (See Section 8).
Methods and materials for
containment and cleaning up
Ventilate well, stop flow of gas or liquid if possible. Immediately contact emergency personnel.
Environmental precautions
Should not be released into the environment. Prevent further leakage or spillage if safe to do so.
Prevent from entering into soil, ditches, sanitary sewers, waterways and/or groundwater.
7. Handling and storage
Precautions for safe handling
Eliminate all sources of ignition. Wear appropriate personal protective equipment (See Section 8).
Eating, drinking, and smoking should be prohibited in areas where this material is handled, stored,
and processed. Do not breathe gas. Do not get in eyes, on skin, on clothing. Use only with
adequate ventilation.
