Autoignition temp.: 748 °F; 398 °C

Extinguishing Media: water spray. alcohol resistant foam. dry chemical, carbon dioxide. Fire Fighting Procedures: use water spray. Cool tank/ container. wear self-contained breathing apparatus. Wear structural firefighters protective clothing.

Extinguishing Media: water spray. alcohol resistant foam. dry chemical, carbon dioxide.

6. ACCIDENTAL RELEASE MEASURES

SAFEGUARDS (PERSONNEL): use appropriate personal protective equipment

during clean-up . Evacuate personnel, thoroughly ventilate area, and use self-contained breathing apparatus.

Initial Containment: remove source of heat, sparks, flame, impact, friction or electricity. dike spill.

Prevent material from entering sewers, water ways, or low areas.

Spill cleanup: recover free liquid for reuse or reclamation. Soak up with saw dust, sand, oil dry or other ab sorbent material.

7. HANDLING AND STORAGE

Keep in cool, dry place. Keep in well ventilated space. Storage has temperature limits. NFPA class IIIB storage. Consult NFPA and OSHA codes. Avoid prolonged breathing of mist or vapor. Avoid prolonged or repeated contact with skin. Wash thoroughly after handling.

8. EXPOSURE CONTROLS / PERSONAL PROTECTION

Consult with a health/safety professional for specific selection ventilation ventilate as needed to comply with exposure limit. Local exhaust ventilation recommended. Mechanical ventilation recommended personal protective equipment.

Eye: splash proof chemical goggles recommended to protect against splash of product.

Gloves: protective gloves recommended when prolonged skin contact cannot be avoided. polyethylene; neoprene; nitrile; polyvinyl alcohol; natural rubber; butyl rubber.

Respirator: concentration-in-air determines protection needed. use only niosh certified respiratory protection. Respiratory protection usually not needed unless product is heated or misted. Half-mask air purifying respirator with organic vapor cartridges is acceptable to 10 times the exposure limit. Full-face air purifying respirator with organic vapor cartridges is acceptable to 50 times the exposure limit not to exceed the cartridge limit of 1000 ppm. Protection by air purifying respirators is limited. Use a positive pressure-demand full-face supplied air respirator or SCBA for exposures above 50x the exposure limit. if exposure is above IDLH (immediately dangerous to life & health) or there is the possibility of an uncontrolled release or exposure levels are unknown then use a positive pressuredemand full-face supplied air respirator with escape bottle or SCBA.
