explode if exposed to sufficient 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. 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
