Section 5 - Fire Fighting Measures
General Containers can build up pressure if exposed to heat and/or fire. As in
Informatio any fire, wear a self-contained breathing apparatus in pressure-
demand, MSHA/NIOSH (approved or equivalent), and full protective
n
gear. Vapors may form an explosive mixture with air.
Vapors can travel to a source of ignition and flash back. Containers
may explode in the heat of a fire. Flammable solid.
Extinguishi Use water spray to cool fire-exposed containers. Use foam, dry
ng Media chemical, or carbon dioxide. Water may be ineffective.
Section 6 - Accidental Release Measures
General Use proper personal protective equipment as indicated in Section 8.
Informati
on
Spills/Le Vacuum or sweep up material and place into a suitable disposal
aks container. Remove all sources of ignition. Use a spark-proof tool.
Section 7 - Handling and Storage
Handlin Use spark-proof tools and explosion proof equipment. Do not breathe dust,
vapor, mist, or gas. Do not get in eyes, on skin, or on clothing. Use only in

Storage Keep away from sources of ignition. Store in a tightly closed container.
Store in a dry area. Refrigerator/flammables.
Section 8 - Exposure Controls, Personal Protection
Engineeri Facilities storing or utilizing this material should be equipped with an
ng eyewash facility and a safety shower. Use adequate general or local
Controls explosion-proof ventilation to keep airborne levels to acceptable levels.
PERSONAL PROTECTIVE EQUIPMENT
Eyes Wear chemical goggles.
Skin Wear appropriate protective gloves to prevent skin exposure.
Clothing Wear appropriate protective clothing to prevent skin exposure.
Respirato Follow the OSHA respirator regulations found in 29CFR 1910.134 or
