4. FIRST AID MEASURES-----------Up to Table of Contents
INHALATION:
Remove from exposure immediately. Use a bag valve mask or similar device to perform artificial
respiration (rescue breathing) if needed. Get medical attention.
SKIN CONTACT:
Remove contaminated clothing, jewelry, and shoes immediately. Wash with soap or mild
detergent and large amounts of water until no evidence of chemical remains (at least 15-20
minutes). Get medical attention, if needed.
EYE CONTACT:
Wash eyes immediately with large amounts of water or normal saline, occasionally lifting upper
and lower lids, until no evidence of chemical remains. Get medical attention immediately.
INGESTION:
Never make an unconscious person vomit or drink fluids. Give sodium bicarbonate solution.
When vomiting occurs, keep head lower than hips to help prevent aspiration. If person is
unconscious, turn head to side. Get medical attention immediately.
ANTIDOTE:
amyl nitrite, inhalation; sodium nitrite, intravenous; pyridoxine, intravenous; urea, intravenous.
CAUTION! Get medical attention immediately.
NOTE TO PHYSICIAN:
For ingestion, consider gastric lavage.
5. FIRE FIGHTING MEASURES-----------Up to Table of Contents
FIRE AND EXPLOSION HAZARDS:
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.
EXTINGUISHING MEDIA:
regular dry chemical, carbon dioxide, water, regular foam
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. 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 or
combustion by-products. Stay upwind and keep out of low areas.
FLASH POINT:
-6 F (-21 C) (OC)
FLAMMABILITY CLASS (OSHA):
IB
6. ACCIDENTAL RELEASE MEASURES-----------Up to Table of Contents
OCCUPATIONAL RELEASE:
Avoid heat, flames, sparks and other 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. Remove sources of ignition. Keep unnecessary people away, isolate hazard area and
deny entry.
7. HANDLING AND STORAGE-----------Up to Table of Contents
Store and handle in accordance with all current regulations and standards. Subject to storage
regulations: U.S. OSHA 29 CFR 1910.106. Grounding and bonding required. Keep separated
