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 immediately.
: In case of contact, immediately flush skin with plenty of water. Remove contaminated

Section 5. Fire fighting measures
Flammability of the product : Non-flammable.
: Use an extinguishing agent suitable for surrounding fires.
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.

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
: Avoid contact with eyes, skin and clothing. Keep container closed. Use only with
Handling
adequate ventilation. Do not puncture or incinerate container. Wash thoroughly after
handling. 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.
Never allow any unprotected part of the body to touch uninsulated pipes or vessels that
contain cryogenic liquids. Prevent entrapment of liquid in closed systems or piping
without pressure relief devices. Some materials may become brittle at low temperatures
and will easily fracture.
: 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 掳C
(125 掳F).
