SDS

Skin contact
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.
Eye contact
Rinse with water. Get medical attention if irritation develops and persists.
Ingestion
Rinse mouth. If ingestion of a large amount does occur, call a poison control center immediately.
Most important
symptoms/effects, acute and
delayed
Direct contact with eyes may cause temporary irritation. Contact with liquefied gas might cause
frostbites, in some cases with tissue damage.
Indication of immediate
medical attention and special
treatment needed
Provide general supportive measures and 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
Use fire-extinguishing media appropriate for surrounding materials.
Unsuitable extinguishing
media
Do not use water jet as an extinguisher, as this will spread the fire.
Specific hazards arising from
the chemical
Contents under pressure. Pressurized container may explode when exposed to heat or flame.
Greatly increases the burning rate of combustible materials. Fire may produce irritating, corrosive
and/or toxic gases. During fire, gases hazardous to health may be formed.
Special protective equipment
and precautions for firefighters
Firefighters must use standard protective equipment including flame retardant coat, helmet with
face shield, gloves, rubber boots, and in enclosed spaces, SCBA. In the event of fire, wear
self-contained breathing apparatus.
Fire-fighting
equipment/instructions
In case of fire: Stop leak if safe to do so. Allow gas to burn if flow cannot be shut off immediately.
Apply water from safe distance to cool container and protect surrounding area. Cylinders can burst
violently when heated, due to excess pressure build-up. Remove pressurized gas cylinders from
the immediate vicinity. Move containers from fire area if you can do so without risk. Do not direct
water at source of leak or safety devices as icing may occur. Use water spray to cool unopened
containers. Evacuate area and fight fire from a safe distance.
General fire hazards
Greatly increases the burning rate of combustible materials.
6. Accidental release measures
Personal precautions,
protective equipment and
emergency procedures
Keep unnecessary personnel away. Keep people away from and upwind of spill/leak. Keep out of
low areas. Eliminate all ignition sources (no smoking, flares, sparks or flames in immediate area).
Wear appropriate personal protective equipment. Do not touch damaged containers or spilled
material unless wearing appropriate protective clothing. Ventilate closed spaces before entering
them. Local authorities should be advised if significant spillages cannot be contained. For personal
protection, see section 8 of the SDS.
Methods and materials for
containment and cleaning up
Extinguish all flames in the vicinity. 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. Water may be used to flush spills
away from sources of ignition. Do not get water inside container. Prevent entry into waterways,
sewer, basements or confined areas. Following product recovery, flush area with water. For waste
disposal, see section 13 of the SDS.
Environmental precautions
Runoff from fire control or dilution water may cause pollution.
7. Handling and storage
Precautions for safe handling
Do not handle, store or open near an open flame, sources of heat or sources of ignition. Protect
material from direct sunlight. Keep away from combustible material. Keep reduction valves free
from grease and oil. Provide adequate ventilation. Wear appropriate personal protective
equipment. Observe good industrial hygiene practices. Use care in handling/storage.
Conditions for safe storage,
including any incompatibilities
Keep away from heat and sources of ignition. Store in original tightly closed container. Store in a
cool, dry place out of direct sunlight. Store in a well-ventilated place. Secure cylinders in an upright
position at all times, close all valves when not in use. Store away from incompatible materials (see
Section 10 of the SDS). Do not store near combustible materials.
8. Exposure controls/personal protection
Occupational exposure limits
No exposure limits noted for ingredient(s).
Biological limit values
No biological exposure limits noted for the ingredient(s).
