Section 4. First aid measures
No action shall be taken involving any personal risk or without suitable training.If fumes are still suspected to be present,
the rescuer should wear an appropriate mask or a self-contained breathing apparatus.It may be dangerous to the person
providing aid to give mouth-to-mouth resuscitation.
: In case of contact, immediately flush eyes with plenty of water for at least 15 minutes.
Eye contact
Get medical attention if irritation occurs.
: Wash with soap and water. Get medical attention if irritation develops.
Skin contact
: Try to warm up the frozen tissues and seek medical attention.
Frostbite
: If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is
Inhalation
difficult, give oxygen. Get medical attention if symptoms appear.
: Do NOT induce vomiting unless directed to do so by medical personnel. Never give

Products of combustion :
Extremely flammable in presence of oxidizing materials.
Fire hazards in presence of :
various substances
: In case of fire, use water spray (fog), foam, dry chemicals, or CO 2.
Fire fighting media and
instructions
If involved in fire, shut off flow immediately if it can be done without risk. Apply water
from a safe distance to cool container and protect surrounding area.
Extremely flammable. Gas may accumulate in confined areas, travel considerable
distance to source of ignition and flash back causing fire or explosion.

Section 6. Accidental release measures
: Immediately contact emergency personnel. Keep unnecessary personnel away. Use
Personal precautions
suitable protective equipment (Section 8). Shut off gas supply if this can be done safely.
Isolate area until gas has dispersed.
Environmental precautions : Avoid dispersal of spilled material and runoff and contact with soil, waterways, drains
and sewers.
Section 7. Handling and storage
: Keep container closed. Use only with adequate ventilation. Keep away from heat,
Handling
sparks and flame. To avoid fire, minimize ignition sources. Use explosion-proof
electrical (ventilating, lighting and material handling) equipment. Do not puncture or
incinerate container. High pressure gas. Use equipment rated for cylinder pressure.
Close valve after each use and when empty. Protect cylinders from physical damage; do
not drag, roll, slide, or drop. Use a suitable hand truck for cylinder movement.
: Keep container tightly closed. Keep container in a cool, well-ventilated area. Cylinders
Storage
should be stored upright, with valve protection cap in place, and firmly secured to
prevent falling or being knocked over. Cylinder temperatures should not exceed 52 癈
(125 癋).
Section 8. Exposure Controls, Personal Protection
: Use only with adequate ventilation. Use process enclosures, local exhaust ventilation, or
Engineering controls
other engineering controls to keep airborne levels below recommended exposure limits.
The engineering controls also need to keep gas, vapor or dust concentrations below any
explosive limits. Use explosion-proof ventilation equipment.
