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 for at least 15 minutes
Skin contact
while removing contaminated clothing and shoes. Wash clothing before reuse.
Thoroughly clean shoes before reuse. Get medical attention immediately.
: 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 immediately.
: Do NOT induce vomiting unless directed to do so by medical personnel. Never give

anything by mouth to an unconscious person. Get medical attention if symptoms
appear.
Section 5. Fire fighting measures
Flammable.
Flammability of the product :
Lower: 12% Upper: 29%
Flammable limits :
These products are carbon oxides (CO, CO 2), sulfur oxides (SO 2, SO3...).
Products of combustion :
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.
: Fire fighters should wear appropriate protective equipment and self-contained breathing

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 safety.
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. Keep away from heat, 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. Wash thoroughly after
handling. High pressure gas. Use equipment rated for cylinder pressure. Close valve
after each use and when empty.
: Keep container in a cool, well-ventilated area. Keep container tightly closed and sealed
Storage
until ready for use. Avoid all possible sources of ignition (spark or flame). Segregate
from oxidizing materials.

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.
Personal protection
: 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.
: Personal protective equipment for the body should be selected based on the task being
Skin
performed and the risks involved and should be approved by a specialist before handling
this product.
: Use a properly fitted, air-purifying or air-fed respirator complying with an approved
Respiratory
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.
: Chemical-resistant, impervious gloves or gauntlets complying with an approved standard
Hands
should be worn at all times when handling chemical products if a risk assessment
indicates this is necessary.
Personal protection in case : Full chemical resistant suit and self-contained breathing apparatus only by trained and
