6. SPILL OR LEAK PROCEDURES
Steps to be Taken in Case Material is Released or Spilled:
Ventilate area of spill. Eliminate all sources of ignition.
Remove all non-essential personnel from area. Clean-up personnel should
wear proper protective equipment and clothing. Absorb material with
suitable absorbent and containerize for disposal.
7. SPECIAL PRECAUTIONS
Precautions to be Taken in Handling or Storing: Store in a cool, dry,
well-ventilated area suitable for storage of flammable materials. Store
away from direct heat or sunlight, ignition sources, strong oxidizers,
acids, bases, amines, anhydrides, halogens, phenols, alcohols, ketones,
and icosyanates. Avoid skin contact. Do not breathe vapor.
Other Precautions: Residue may make empty containers dangerous.
8. SPECIAL PROTECTION INFORMATION
Respiratory Protection(Specify Type):
A NIOSH/MSHA chemical cartridge respirator should be worn if PEL or
TLV is exceeded.
Ventilation:
Local Exhaust: Preferred. Use hood, local exhaust, or other
engineering controls to keep airborne levels below PEL or TLV.
Mechanical(General): Acceptable if air exchange is sufficient
to maintain airborne levels below PEL or TLV.
Special: No
Other: No
Protective Gloves: Natural rubber, Neoprene, PVC or equivalent.
Eye Protection: Splash proof chemical safety goggles and face shield
should be worn.
Other Protective Clothing or Equipment: Lab coat, apron, boots, eye
wash, safety shower.
