Reports of Carcinogenicity:NTP:No IARC:No OSHA:No
Medical Cond Aggravated by Exposure:

First Aid: 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:
Wash exposed skin with soap and water. 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.

Flash Point:-369 F (-223 C) (METHANE)
Extinguishing Media:carbon dioxide, regular dry chemical, regular foam,
water
Fire Fighting Procedures:Move container from fire area if it can be
done without risk. Cool containers with water spray until well
after the fire is out. Avoid inhalation of material or combustion
by-products. Stay upwind and keep out of low areas.
Unusual Fire/Explosion Hazard:Severe fire hazard. Containers may
rupture or explode if exposed to heat.

Spill Release Procedures:Avoid heat, flames, sparks and other sources
of ignition. Do not touch spilled material. 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.
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).
Neutralizing Agent:

Handling and Storage Precautions:Store and handle in accordance with
all current regulations and standards. Grounding and bonding
required. Subject to storage regulations: U.S. OSHA 29 CFR
1910.101. See original container for storage recommendations. Keep
separated from incompatible substances.
Other Precautions:

Respiratory Protection: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. For Unknown Concentrations or
Immediately Dangerous to Life or Health - Any supplied-air
respirator with full facepiece and operated in a pressure-demand or
other positive-pressure mode in combination with a separate escape
supply. Any self-contained breathing apparatus with a full
facepiece.
Ventilation:Ventilation equipment should be explosion-resistant if
explosive concentrations of material are present. Provide local
exhaust ventilation system. Ensure compliance with applicable
exposure limits.
Protective Gloves:Wear appropriate chemical resistant gloves.
Eye Protection:Wear splash resistant safety goggles. Provide an
emergency eye wash fountain and quick drench shower in the
immediate work area.
Other Protective Equipment:Wear appropriate chemical resistant
clothing.
