gas 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 PHYSICAL DATA
