------------------------------------------------------------------------------
SECTION 5 FIRE FIGHTING MEASURES
------------------------------------------------------------------------------
FIRE AND EXPLOSION HAZARDS: Negligible fire hazard. Containers may rupture or
explode if exposed to heat. Gas/air mixtures are explosive.
EXTINGUISHING MEDIA: carbon dioxide, regular dry chemical
Large fires: Use regular foam or flood with fine water spray.
FIRE FIGHTING: Move container from fire area if it can be done without risk.
Cool containers with water spray until well after the fire is out. Stay away
from the ends of tanks. For fires in cargo or storage area: Cool containers
with water from unmanned hose holder or monitor nozzles until well after
fire is out. If this is impossible then take the following precautions: Keep
unnecessary people away, isolate hazard area and deny entry. Let the fire
burn. Use extinguishing agents appropriate for surrounding fire. Cool
containers with water spray until well after the fire is out. Apply water
from a protected location or from a safe distance. Do not get water directly
on material. Reduce vapors with water spray. Avoid inhalation of material or
combustion by-products. Stay upwind and keep out of low areas. Consider
downwind evacuation if material is leaking.

HEALTH EFFECTS:
INHALATION:

can result in headache and serious anoxia causing fatal cardiac
arrhythmias or brain damage with cerebral edema, permanent mental deficit,

Material Safety Data Sheet #16790 wysiwyg://content.511/http://www.mgindustries.com/msds/SubLookup.asp?SubName=16790&SUBMIT1=Go%21
and visual system involvement. High concentrations mixed with air or
oxygen may produce signs of central nervous system depression including
drowsiness, lightheadedness, confusion, hysteria, anesthesia, and
unconsciousness. Some persons may experience nausea, and occasionally
vomiting, following anesthesia. Anesthetic concentrations may produce
permanent hearing loss in persons who have had middle ear surgery.
Exposure of pregnant rats to 75% nitrous oxide for 8 hours on the 15th day
of gestation resulted in permanent alterations in neurobehavioral output
of the newborns as exhibited by hyperactivity in males and hypoactivity in
females.
CHRONIC EXPOSURE:
NITROUS OXIDE: Prolonged occupational exposure or abuse has resulted in
neurologic effects including initial signs of numbness, paresthesias, and
loss of pain and temperature sensation, progressing to muscle weakness,
loss of balance, gait ataxia, Lhermitte's sign, impotence, sphincter
difficulties, loss of bladder and vaginal sensation, and reduction in
dexterity, cognition, and motor and audiovisual skills. Recovery may occur
in months, but damage may be permanent. Signs of bone marrow depression
including fatal aplastic anemia have been reported. There have also been
increased incidences of kidney and liver disorders, spontaneous abortions,
and fetal malformations reported among dentists and their assistants.
Exposure to nitrous oxide in utero prior to organogenesis resulted in
physical malformations in rat fetuses; permanent alterations in brain
function can result following exposure during a period beyond major
organogenesis. Prolonged exposure produced some damage to chromosomes in
bone marrow cells and spermatogonial cells in male rats. 500 ppm 8
hrs/day/35 days disrupted hormonal cycles and decreased conception in
female rats.
SKIN CONTACT:
ACUTE EXPOSURE:
NITROUS OXIDE: No adverse effects have been reported from the gas. Due to
rapid evaporation, the liquid may cause frostbite with redness, tingling,
and pain or numbness. In more severe cases, the skin may become hard and
white and blisters may form.
CHRONIC EXPOSURE:
NITROUS OXIDE: No data available.
EYE CONTACT:
ACUTE EXPOSURE:
NITROUS OXIDE: No adverse effects have been reported from the gas. Due to
rapid evaporation, the liquid may cause frostbite with redness, pain, and
blurred vision.
