Reports of Carcinogenicity:NTP:No IARC:No OSHA:No
Health Hazards Acute and Chronic:INHALATION: SHORT TERM EXPOSURE:
irritation, headache, drowsiness, symptoms of drunkenness LONG TERM

Medical Cond Aggravated by Exposure:

First Aid: INHALATION: If adverse effects occur, remove to
uncontaminated area. Give artificial respiration if not breathing.
Get immediate medical attention. SKIN CONTACT: Wash skin with soap
and water for at least 15 minutes while removing contaminated
clothing and shoes. Get medical attention, if needed. Thoroughly
clean and dry contaminated clothing and shoes before reuse. EYE
CONTACT: Flush eyes with plenty of water for at least 15 minutes.
Then get immediate medical attention. INGESTION: If vomiting
occurs, keep head lower than hips to help prevent aspiration. If
person is unconscious, turn head to side. Get medical attention
immediately. NOTE TO PHYSICIAN: For ingestion, consider gastric
lavage. Consider oxygen.

Flash Point:-20 F (-29 C)
Autoignition Temp:496 F (258 C)
Lower Limits:1.0-1.2%
Upper Limits:8.34-8.35%
Extinguishing Media:alcohol resistant foam, carbon dioxide, regular dry
chemical, water Large fires: Use alcohol-resistant foam or flood
with fine water spray.
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. 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. 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: Evacuation radius: 800 meters
(1/2 mile). Do not attempt to extinguish fire unless flow of
material can be stopped first. Flood with fine water spray. Do not
scatter spilled material with high-pressure water streams. Cool
containers with water spray until well after the fire is out. Apply
water from a protected location or from a safe distance. Avoid
inhalation of material ocombustion by-products. Stay upwind and
keep out of low areas. Water may be ineffective.
Unusual Fire/Explosion Hazard:Severe fire hazard. Vapor/air mixtures
are explosive. The vapor is heavier than air. Vapors or gases may
ignite at distant ignition sources and flash back.

Spill Release Procedures:Avoid heat, flames, sparks and other sources
of ignition. Remove sources of ignition. Stop leak if possible
without personal risk. Reduce vapors with water spray. Small
spills: Absorb with sand or other non-combustible material. Collect
spilled material in appropriate container for disposal. Large
spills: Dike for later disposal. Keep unnecessary people away,
isolate hazard area and deny entry. Stay upwind and keep out of low
areas.
Neutralizing Agent:

Handling and Storage Precautions:Grounding and bonding required.
Subject to storage regulations: U.S. OSHA 29 CFR 1910.106. Protect
from physical damage. Store outside or in a detached building.
Inside storage: Store with flammable liquids. Keep separated from
incompatible substances. Store in a tightly closed container. Store
in a cool, dry place. Store in a well-ventilated area. Avoid
contact with light.
Other Precautions:

Respiratory Protection: METHYLCYCLOPENTANE: No occupational exposure
limits established.
Ventilation:Provide local exhaust ventilation system. Ventilation
equipment should be explosion-resistant if explosive concentrations
of material are present. Ensure compliance with applicable exposure
limits.
Protective Gloves:Wear appropriate chemical resistant gloves.
Eye Protection:Wear splash resistant safety goggles with a faceshield.
Provide an emergency eye wash fountain and quick drench shower in
the immediate work area.
Other Protective Equipment:Wear appropriate chemical resistant
clothing.
Supplemental Safety and Health
