health hazards acute and chronic: at low oxygen concentrations
unconsciousness & death may occur in seconds w/out warning.

extensive tissue damage or burns can result from exposure to liquid
nitrogen or cold nitrogen vapors.

explanation of carcinogenicity: nitrogen is a simple asphyxiant and has
no threshold limit value.

effects of overexposure: oyxgen deficient atmospheres may produce
dizziness, nausea, vomiting, loss of consciousness and death.

nitrogen under high pressure can produce narcosis even though
oxygen sufficient for life is pre sent.

First Aid

First aid: assisted respiration/supplemental oxygen should be given if
the victim is not breathing. If cryogenic liq./cold boil off gas
contacts a worker's skin or eyes,frozen tissues should be
flooded/soaked w/tepid water. Do not use hot water!!Cryogenic
burns which results in blistering/deeper tissue freezing should be
seen promptly by a physician. Move person to a area with normal

rtecs #: qw9700000
acgih tlv: asphyxiant; 9192

Hazards

Health hazards acute and chronic: nitrogen is odorless & nontoxic, but
may produce suffocation by diluting conc of oxygen below necessary
levels. At low oxygen concentrations (>19.5%) unconsciousness and
death may occur in seconds wit hout warning. Extensive tissue
damage or burns can result from exposure to liquid nitrogen or cold
nitrogen vapors.

effects of overexposure: exposure to oxygen deficient atmosphere may
produce dizziness, nausea, vomiting, loss of consciousness, and
death. Death may result from errors in judgement, confusion, loss
of consciousness which pre vents self-rescue. Nitrogen under high
pressure can produce narcosis even though oxygen sufficient for
life present.

medical cond aggravated by exposure: n/k nitrogen is a simple asphyxiant
and constitues 78% of the air we breathe. Nitrogen does not support
life and may produce immediately hazardous atmospheres thru
displacement of oxygen.

First Aid

First aid: move persons suffering from lack of oxygen to areas w/normal
atmospheres. Scba may be req'd to prevent asphyxiation of rescue
workers. Give assisted resp & oxygen if not breathing. If cryogenic
liquid /cold boil-off gas contacts skin/eyes, flood/soak frozen
tissue w/ tepid water (105-115f) don't use hot water. Cryogenic
burns which result in blistering or deeper tissue freezing, promply

Reactivity

Hazard and precautions: target organs: respiratory system. Acute- nitrogen is
nontoxic but can produce suffocation by displacing oxygen. Prolonged
inhalation can cause unconsciousness, convulsive movements, possible death.

ca nnot be swallowed/contacted. Chronic- none. Store in cool, ventilated
area. If leak is from cylinder/its valve, contact your supplier. Atmosphere
must have at least 19.5% oxygen before personnel can b e allowed in. First
aid- prompt medical attention is mandatory in all cases of overexposure.

rescue personnel should wear self-contained breathing apparatus.

inhaled: remove to fresh air. Provide oxyge n/cpr if needed.

eye/skin/oral: unlikely (gas)

Proper Disposal

spill release procedures: evacuate all personnel from affected area. Use
appropriate protective equipment. Ventilate area. If leak is from cylinder or
its valve, contact your supplier. The atmosphere must have at least 19.5% o
xygen before personnel can be allowed in the area.

neutralizing agent: not relevant
waste disposal methods: dispose of in accordance with local, state and federal
regulations. Do not attempt to dispose of residual or unused quantities.

return in the shipping container properly labeled, with any valve or cap s
secured to your supplier for proper disposal.

handling and storage precautions: store cylinders upright, secure, in cool,
dry, ventilated area below 125f. Protect from physical damage. Full &
empty cylinders should be segregated.

other precautions: be aware that exposures to fatal concentrations of nitrogen
could occur without any significant warning symptoms. Use a "first in-first
out" inventory system. Close valve after each use and when empty .

Hazards

Ld50 lc50 mixture: none provided by mfr.

reports of carcinogenicity: ntp: no iarc: no osha: no
health hazards acute and chronic: nitrogen is nontoxic but the
liberation of a large amount in a confined area could displace the
amount of oxygen in air necessary to support life. Frostbite
effects are a change in color of the skin t o gray or white
possibly followed by blistering. Contact with the cryogenic liquid
or cold piping containing the liquid can cause tissue freezing or
frostbite on dermal contact or if splashed into the eyes.

explanation of carcinogenicity: none provided by mfr.

effects of overexposure: effects of exposure to high concentrations that
displaces oxygen in air necessary for life may include any, all,
or none of following: loss of balance, dizziness, tightness in
frontal area of foreh ead, tingling of tongue, fingertips, toes,
weakened speech leading to inability to utter sounds, rapid
reduction in ability to perform movements, reduced consciousness of
surroundings, loss of tactile sensations, heightened mental
activity. It should be recongnized that it is possible that none of
above symptoms may occur in nitrogen asphyxia so that there are no
definite warning symptoms.

First Aid

First aid: prompt medical attention is mandatory in all cases of
overexposure to nitrogen. Rescue personnel should be equipped with
self contained breathing apparatus. Inhalation: move conscious
persons to fresh air. Quick removal from contaminated area is
most important. Move unconscious persons to fresh air and given
mouth-to-mouth resuscitation and oxygen. Get medical attention
immediately. For dermal co ntact or frostbite, flush affected areas
with lukewarm water. Do not use hot water. Get medical attention if
cryogenic "burn" has resulted in blistering or deep tissue
freezing.
