Section 4. First aid measures
No action shall be taken involving any personal risk or without suitable training.If it is suspected that fumes are still present,
the rescuer should wear an appropriate mask or self-contained breathing apparatus.It may be dangerous to the person
providing aid to give mouth-to-mouth resuscitation.
Eye contact : Check for and remove any contact lenses. Immediately flush eyes with plenty of water
for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical
attention immediately.
Skin contact : In case of contact, immediately flush skin with plenty of water for at least 15 minutes
while removing contaminated clothing and shoes. Wash clothing before reuse. Clean
shoes thoroughly before reuse. Get medical attention immediately.
Frostbite : Try to warm up the frozen tissues and seek medical attention.
Inhalation : Move exposed person to fresh air. If not breathing, if breathing is irregular or if
respiratory arrest occurs, provide artificial respiration or oxygen by trained personnel.
Loosen tight clothing such as a collar, tie, belt or waistband. Get medical attention
immediately.
Ingestion : As this product is a gas, refer to the inhalation section.

Fire-fighting media and : Use an extinguishing agent suitable for the surrounding fire.
instructions
Apply water from a safe distance to cool container and protect surrounding area. If
involved in fire, shut off flow immediately if it can be done without risk.
Contains gas under pressure. In a fire or if heated, a pressure increase will occur and
the container may burst or explode.
Special protective : Fire-fighters should wear appropriate protective equipment and self-contained breathing
apparatus (SCBA) with a full face-piece operated in positive pressure mode.

Section 6. Accidental release measures
Personal precautions : Immediately contact emergency personnel. Keep unnecessary personnel away. Use
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.
Methods for cleaning up : Immediately contact emergency personnel. Stop leak if without risk. Note: see section 1
for emergency contact information and section 13 for waste disposal.
Section 7. Handling and storage
Handling : Use only with adequate ventilation. Wash thoroughly after handling. High pressure gas.
Do not puncture or incinerate container. Use equipment rated for cylinder pressure.
Close valve after each use and when empty. Do not get in eyes, on skin or on clothing.
Keep container closed. Do not get on skin or clothing. Protect cylinders from physical
damage; do not drag, roll, slide, or drop. Use a suitable hand truck for cylinder
movement.
Storage : Cylinders 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).
Section 8. Exposure controls/personal protection
Engineering controls : Use only with adequate ventilation. Use process enclosures, local exhaust ventilation or
other engineering controls to keep worker exposure to airborne contaminants below any
recommended or statutory limits.
Personal protection
Eyes : Safety eyewear complying with an approved standard should be used when a risk
assessment indicates this is necessary to avoid exposure to liquid splashes, mists or
dusts.
Skin : Personal protective equipment for the body should be selected based on the task being
performed and the risks involved and should be approved by a specialist before handling
this product.
Respiratory : Use a properly fitted, air-purifying or air-fed respirator complying with an approved
standard if a risk assessment indicates this is necessary. Respirator selection must be
based on known or anticipated exposure levels, the hazards of the product and the safe
working limits of the selected respirator.
The applicable standards are (US) 29 CFR 1910.134 and (Canada) Z94.4-93
Hands : Chemical-resistant, impervious gloves complying with an approved standard should be
worn at all times when handling chemical products if a risk assessment indicates this is
necessary.
Personal protection in case : Self-contained breathing apparatus (SCBA) should be used to avoid inhalation of the
product. Full chemical-resistant suit and self-contained breathing apparatus should be
of a large spill
worn only by trained and authorized persons.
