3 HAZARDS IDENTIFICATION Main Hazards All cylinders are portable
gas containers, and must be regarded as pressure vessels at all
times. R*2 does not support life. It can act as a simple asphyxiant
by diluting the concentration of oxygen in air to below the levels
necessary to support life. Adverse Contains a liquefied gas.
Contact with liquid Health effects may cause frostbite and injury
to the cornea. Chemical Heating will cause a rise in pressure with
a risk hazards of bursting. On combustion, toxic gases are
released. Biological Contact with the liquid phase could cause
hazards freeze burns. 4 FIRST AID MEASURES Prompt medical attention
is mandatory in all cases of overexposure to vaporised R*2. Rescue
personnel should be equipped with self-contained breathing
apparatus. Conscious persons should be assisted to an
uncontaminated area and inhale fresh air. Quick removal from the
contaminated area is most important. Unconscious persons should be
removed to an uncontaminated area and given mouth-to-mouth
resuscitation and supplemental oxygen. The use of adrenaline or
similar drugs should be avoided. Eye contact (Vapour) No known
effect. (Liquid) Immediately flush with large quantities of tepid
water, or with sterile saline solution. Seek medical attention.
Skin contact (Vapour) No known effect. (Liquid) In case of
frostbite from contact with liquid R*2, place the frost-bitten part
in warm water, about ****2°C. If warm water is not available, or is
impractical to use, wrap the affected part gently in blankets.
Encourage the patient to exercise the affected part whilst it is
being warmed. Do not remove clothing whilst frosted.. Ingestion
Provided the patient is conscious, wash out the mouth with water,
and give ******0 ml to drink. Obtain immediate medical attention. 5
FIRE FIGHTING MEASURES Extinguishing As R*2 is non-flammable, it
will not Media contribute to the fire, but could help with the
extinguishing by reducing the oxygen content of the air by dilution
to below the level to support combustion. If possible shut off the
source of R*2. Evacuate area. All cylinders should be removed from
the vicinity of the fire. Cylinders that cannot be removed should
be cooled with water from a safe distance. Cylinders which have
been exposed to excessive heat should be clearly identified for
inspection. Specific Pressurised container. On heating there is a
risk hazards of bursting due to internal pressure build-up NOT
flammable. However, it may present a risk in the event of fire.
Toxic vapours (Halogen compounds ) are released. Vapour / air
mixture may be flammable under specific conditions. Protective
Self-contained breathing apparatus. Safety gloves Clothing and
shoes, or boots, should be worn when handling cylinders.
Environmental precautions. Care should be taken when entering a
potentially oxygen-deficient environment. If possible, ventilate
the affected area. 6 ACCIDENTAL RELEASE MEASURES Personal
Precautions. Do not enter any areas where R*2 has been spilled
unless tests have shown that it is safe to do so. Environmental
Prevent the product from spreading into the Precautions
environment. Contain the spilled material by bunding. Small spills
Shut off source of the R*2. Ventilate the area. Large spills
Evacuate the area. Shut off the source of the spill if this can be
done without risk. Restrict access to the area until completion of
the clean-up procedure. Ventilate the area using forced-draught if
necessary. 7 HANDLING AND STORAGE Do not allow cylinders to slide
or come into contact with sharp edges. R*2 cylinders should be
stacked vertically at all times, and should be firmly secured in
order to prevent them from being knocked over. Use a “first in -
first out?inventory system to prevent full cylinders from being
stored for excessive periods of time. Keep out of reach of
children. 8 EXPOSURE CONTROLS/PERSONAL PROTECTION Occupational
exposure hazards As R*2 is a simple asphyxiant, avoid any areas
where spillage has taken place. Only enter once testing has proved
the atmosphere to be safe, and remember that the gas is heavier
than air. Engineering Control measures. Engineering control
measures are preferred to reduce exposure to oxygen depleted
atmospheres. General methods include forced-draught ventilation,
separate from other exhaust ventilation systems. Ensure that
sufficient fresh air enters at, or near, floor level. Personal
protection Self-contained breathing apparatus should always be worn
when entering area where oxygen depletion may have occurred. Safety
goggles, gloves and shoes or boots should be worn when handling
cylinders. Skin No known effect 9 PHYSICAL AND CHEMICAL PROPERTIES
