4. FIRST AID MEASURES
INHALATION: If adverse effects occur, remove to uncontaminated area. Give artificial respiration if not
breathing. If breathing is difficult, oxygen should be administered by qualified personnel. Get immediate
medical attention.
SKIN CONTACT: If frostbite or freezing occur, immediately flush with plenty of lukewarm water (105-
115 F; 41-46 C). DO NOT USE HOT WATER. If warm water is not available, gently wrap affected parts in
blankets. Get immediate medical attention.
EYE CONTACT: Flush eyes with plenty of water.
INGESTION: If a large amount is swallowed, get medical attention.
NOTE TO PHYSICIAN: For inhalation, consider oxygen.
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
Page 3 of 6
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.
6. ACCIDENTAL RELEASE MEASURES
OCCUPATIONAL RELEASE:
Stop leak if possible without personal risk. Avoid contact with combustible materials. Keep unnecessary
people away, isolate hazard area and deny entry. Ventilate closed spaces before entering.
7. HANDLING AND STORAGE
STORAGE: Store and handle in accordance with all current regulations and standards. Subject to storage
regulations: U.S. OSHA 29 CFR 1910.105. Keep separated from incompatible substances.
8. EXPOSURE CONTROLS, PERSONAL PROTECTION
EXPOSURE LIMITS:
NITROUS OXIDE:
50 ppm ACGIH TWA
25 ppm (46 mg/m3) NIOSH recommended TWA (halogenated anesthetic gas)
VENTILATION: Provide local exhaust ventilation system. Ensure compliance with applicable exposure
limits.
EYE PROTECTION: For the gas: Eye protection not required, but recommended. For the liquid: Wear
splash resistant safety goggles. Contact lenses should not be worn. Provide an emergency eye wash fountain
and quick drench shower in the immediate work area.
CLOTHING: For the gas: Protective clothing is not required. For the liquid: Wear appropriate protective,
cold insulating clothing.
GLOVES: Wear insulated gloves.
RESPIRATOR: Under conditions of frequent use or heavy exposure, respiratory protection may be needed.
Respiratory protection is ranked in order from minimum to maximum. Consider warning properties before
use.
Any supplied-air respirator with a full facepiece that is operated in a pressure-demand or other positive-
pressure mode.
Any self-contained breathing apparatus that has a full facepiece and is operated in a pressure-demand or
other positive-pressure mode.
For Unknown Concentrations or Immediately Dangerous to Life or Health -
