4. First-aid measures
Remove from further exposure. For those providing assistance, avoid exposure to yourself or
others. Use adequate respiratory protection. If respiratory tract irritation, dizziness, nausea, or
unconsciousness occurs, seek immediate medical assistance. If breathing has stopped, assist
ventilation with a mechanical device or use mouth-to-mouth resuscitation.
Inhalation
Not likely, due to the form of the product. If frostbite occurs, immerse affected area in warm water
(not exceeding 105°F/41°C). Keep immersed for 20 to 40 minutes. Get medical attention
immediately.
Skin contact
Not likely, due to the form of the product. If frostbite occurs, immediately flush eyes with plenty of
warm water (not exceeding 105°F/41°C) for at least 15 minutes. If easy to do, remove contact
lenses. Get medical attention promptly if symptoms persist or occur after washing.
Eye contact
This material is a gas under normal atmospheric conditions and ingestion is unlikely.
Ingestion
Exposure to rapidly expanding gas or vaporizing liquid may cause frostbite ("cold burn"). Very high
exposure can cause suffocation from lack of oxygen. Symptoms may include loss of
mobility/consciousness. Victim may not be aware of asphyxiation. Asphyxiation may bring about
unconsciousness without warning and so rapidly that victim may be unable to protect themself.
Most important
symptoms/effects, acute and
delayed
Exposure may aggravate pre-existing respiratory disorders. Provide general supportive measures
and treat symptomatically.
Indication of immediate
medical attention and special
treatment needed
If you feel unwell, seek medical advice (show the label where possible). Ensure that medical
personnel are aware of the material(s) involved, and take precautions to protect themselves.
General information
5. Fire-fighting measures
Dry chemical powder. Carbon dioxide (CO2). Water fog. Foam.
Suitable extinguishing media
Do not use water jet as an extinguisher, as this will spread the fire.
Unsuitable extinguishing
media
Extremely flammable gas. Vapors may form explosive mixtures with air. Vapors may travel
considerable distance to a source of ignition and flash back. During fire, gases hazardous to health
may be formed.
Specific hazards arising from
the chemical
Self-contained breathing apparatus and full protective clothing must be worn in case of fire.
Special protective equipment
and precautions for firefighters
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.
Fire fighting
equipment/instructions
Use standard firefighting procedures and consider the hazards of other involved materials. Cool
containers exposed to flames with water until well after the fire is out.
Specific methods
Extremely flammable gas. Contents under pressure. Pressurized container may explode when
exposed to heat or flame.
General fire hazards
6. Accidental release measures
Evacuate the area promptly. No action shall be taken involving any personal risk or without
suitable training. In the event of a leak evacuate all personnel until ventilation can restore oxygen
concentrations to safe levels. Keep unnecessary personnel away. Eliminate all ignition sources (no
smoking, flares, sparks, or flames in immediate area). Do not touch damaged containers or spilled
material unless wearing appropriate protective clothing. Ventilate closed spaces before entering
them. Wear appropriate personal protective equipment (See Section 8).
Personal precautions,
protective equipment and
emergency procedures
Eliminate all ignition sources (no smoking, flares, sparks, or flames in immediate area). Keep
combustibles (wood, paper, oil, etc.) away from spilled material. Stop leak if you can do so without
risk. If possible, turn leaking containers so that gas escapes rather than liquid. Isolate area until
gas has dispersed. For waste disposal, see section 13 of the SDS.
Methods and materials for
containment and cleaning up
Should not be released into the environment. Prevent further leakage or spillage if safe to do so.
