4. FIRST AID MEASURES-----------Up to Table of Contents

INHALATION:

When safe to enter area, remove from exposure. Use a bag valve mask or similar device to

perform artificial respiration (rescue breathing) if needed. Keep warm and at rest. Get medical

attention immediately.



SKIN CONTACT:

Wash if needed. If frostbite, freezing, or cryogenic burns occur, warm affected area in warm

water. If this is not available, gently wrap affected parts in blankets. Allow circulation to return

naturally. Get medical attention immediately.



EYE CONTACT:

Wash eyes immediately with large amounts of water, occasionally lifting upper and lower lids,

until no evidence of chemical remains. Get medical attention immediately.



INGESTION:

If vomiting occurs, keep head lower than hips to help prevent aspiration. Get medical attention, if

needed.



NOTE TO PHYSICIAN:

For inhalation, consider oxygen.





5. FIRE FIGHTING MEASURES-----------Up to Table of Contents



FIRE AND EXPLOSION HAZARDS:

Severe fire hazard. Severe explosion hazard. The vapor is heavier than air. Vapors or gases may

ignite at distant ignition sources and flash back. Vapor/air mixtures are explosive. Electrostatic

discharges may be generated by flow or agitation resulting in ignition or explosion.



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. 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. Withdraw immediately in case of rising

sound from venting safety device or any discoloration of tanks due to fire. For tank, rail car or tank

truck: Stop leak if possible without personal risk. Let burn unless leak can be stopped

immediately. For smaller tanks or cylinders, extinguish and isolate from other flammables.

Evacuation radius: 800 meters (1/2 mile). Stop flow of gas.



FLASH POINT:

-108 F (-78 C)



LOWER FLAMMABLE LIMIT:

3.6%



UPPER FLAMMABLE LIMIT:

33%



AUTOIGNITION:

882 F (472 C)

6. ACCIDENTAL RELEASE MEASURES-----------Up to Table of Contents



WATER RELEASE:

Subject to California Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65).

Keep out of water supplies and sewers.



OCCUPATIONAL RELEASE:

Avoid heat, flames, sparks and other sources of ignition. Stop leak if possible without personal

risk. Reduce vapors with water spray. Keep unnecessary people away, isolate hazard area and

deny entry. Remove sources of ignition. Ventilate closed spaces before entering. Reportable

Quantity (RQ): Notify Local Emergency Planning Committee and State Emergency Response

Commission for release greater than or equal to RQ (U.S. SARA Section 304). If release occurs

in the U.S. and is reportable under CERCLA Section 103, notify the National Response Center at

(800)424-8802 (USA) or (202)426-2675 (USA).
