HEALTH & SAFETY INFORMATION
•
Vapor may cause depression of the central nervous system. Rapid evaporation of
the liquid may cause frostbite. Exposure could cause cardiac arrhythmia and
asphyxiation. In adults, high fluoride exposure over a long time can lead to
skeletal fluorosis with denser bones, joint pain, and a limited range of joint
movement. Although fluoride exposure results in denser bones, the bone appears
to be weaker than normal bone and there may be a greater risk of breaking the
bone.
Animal
studies:
In animals,
exposure to high doses of fluoride can result in decreased fertility and sperm
and testes damage.
Respirator:
At
any concentrations above the NIOSH REL, or where there is no REL, at any
detectable concentration:
SCBAF:PD,PP
(any self-contained breathing apparatus that has a full facepiece and is
operated in a pressure-demand or other positivepressure mode) SAF:PD,PP:ASCBA
(any suppliedair respirator that has a full facepiece and is operated in a
pressure-demand or other positive-pressure mode in combination with an
auxiliary self-contained breathing apparatus operated in a pressure-demand or
other positive pressure mode).
Escape:
GMFOV
[any airpurifying, full-facepiece respirator (gas mask) with a chin-style,
front-or back-,mounted organic vapor canister] SCBAE (any appropriate
escape-type, selfcontained breathing apparatus).
Reactivity:
Violent
reaction with barium, calcium, strontium, finely divided magnesium, and oxides
of these metals. Attacks magnesium and its alloys.
FIRE INFORMATION:
Noncombustible gas.
FIRST AID:
(GAS
) Move victim to fresh air. Call emergency
medical care. Apply artificial respiration if victim is not breathing.
Administer oxygen if breathing is difficult. Remove and isolate contaminated
clothing and shoes. In case of contact with liquefied gas, thaw frosted parts
with lukewarm water. Keep victim warm and quiet. Keep victim under observation.
Ensure that medical personnel are aware of the material(s) involved, and take
precautions to protect themselves. (
REFRIGERATED
LIQUID
) Move victims to
fresh air. Call emergency medical care. Apply artificial respiration if victim
is not breathing. Administer oxygen if breathing is difficult. Clothing frozen
to the skin should be thawed before being removed. In case of contact with
liquefied gas, thaw frosted parts with lukewarm water. Keep victim warm and
quiet. Ensure that medical personnel are aware of the material(s) involved, and
take precautions to protect themselves.
