5. Fire Fighting Measures
Suitable extinguishing media: Water spray, Alcohol-resistant foam, Chemical dry powder,
Carbon dioxide (CO2).
Possible hazard during extinction: Vapor is heavier than air and may spread long distances. Distant
ignition and flashback are possible.
Special extinction procedure: Keep cooling streams of water on fire-exposed tanks or containers.
Special protection for firefighters: Wear protect glove, fire jackets and self-contained breathing
apparatus.
6. Accidental Release
Personal precaution: Restrict access to area until completion of clean-up. Ensure clean-up is conducted
by trained personnel only. Wear adequate personal protective equipment.
Environmental precaution: Extinguish or remove all ignition sources. Prevent material from entering
sewer or confined spaces.
Methods for cleaning up: Stop or reduce leak if safe to do so. Contain spill with earth, sand, or similar
stable, noncombustible material. Small spills: Soak up spill with absorbent
material which does not react with spilled chemical. Put material in suitable,
covered, labeled containers. Flush area with water. Large spills: Contact fire
and emergency services and supplier for advice.
7. Handling and Storage
Handling: Ground drums and bond transfers (Grounding clips must contact bare metal). Keep material
away from sparks, flames, and other ignition sources. Post 鈥淣O SMOKING鈥? signs in area of
use. Have emergency equipment (for fire, spills, leak, etc.) readily available.
Storage: Store in a cool, dry, well-ventilated area, out of direct sunlight. Store away from heat, ignition
source and incompatible materials. Protect from damage. Inspect periodically for deficiencies
such as damage or leaks. Have appropriate fire extinguishers available in and near the
storage area.
