4. FIRST AID MEASURES
INHALATION: If adverse effects occur, remove to uncontaminated area. Give artificial respiration if not
breathing. Get immediate medical attention.
SKIN CONTACT: Wash exposed skin with soap and water.
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 a large amount is swallowed, get medical attention.
5. FIRE FIGHTING MEASURES
FIRE AND EXPLOSION HAZARDS: Negligible fire hazard. Oxidizer. May ignite or explode on contact
with combustible materials. Containers may rupture or explode if exposed to heat.
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
water. Apply water from a protected location or from a safe distance.
6. ACCIDENTAL RELEASE MEASURES
