5. Fire Fighting Measures
Flash Point Not Applicable
Auto-ignition Temperature
Not determined
Flammability Limits in Air
Not determined
Extinguishing Media
On large fires use dry chemical, foam, or water spray. On small fires use carbon dioxide, dry
chemical or water spray. Water can be used to cool fire exposed containers.
Fire Fighting Measures
Self-contained breathing apparatus and protective clothing should be worn when fighting
large fires involving chemicals. Determine the need to evacuate or isolate the area
according to your local emergency plan. Use water spray to keep fire exposed containers
cool.

Unusual Fire or Explosion Hazards
None
Hazardous Decomposition Products
Thermal breakdown of this product during fire or very high heat conditions may evolve the
following hazardous decomposition products:
Carbon oxides and traces of incompletely burned carbon compounds
Formaldehyde
Hydrogen
Silicon dioxide
Metal oxides
Comment
When temperatures above 150掳C in the presence of air, product can form formaldehyde
vapors. Formaldehyde is a potential cancer hazard, a known skin and respiratory sensitizer,
and an irritant to the eyes, nose, throat, skin and digestive system. Safe handling conditions
may be maintained by keeping vapor concentrations within the OSHA Permissible Exposure
Limits for formaldehyde.
6. Accidental Release Measures
Steps to be taken in case of spill or release
Observe all personal protection equipment recommendations. Wipe up or scrape up and
contain for salvage or disposal. Clean area as appropriate since spilled material, even in
small quantities, may present a slip hazard. Final cleaning may require the use of steam,
solvents or detergents. Dispose of saturated absorbent or cleaning materials appropriately,
since spontaneous heating may occur.
Local, state and federal laws and regulations may apply to releases and disposal of this
material, as well as those materials and items employed in the cleanup of releases.
7. Handling and Storage
Handling
Use adequate ventilation. Product evolves acetic acid when exposed to water or humid air.
Provide ventilation during use to control acetic acid within exposure guidelines or use
respiratory protection. Avoid eye contact. Avoid skin contact.
Storage
Use reasonable care and store away from oxidizing materials. Keep container closed and
store away from water or moisture.
8. Exposure Controls and Personal Protection
Note
Acetic acid is formed upon contact with water or humid air. Provide adequate ventilation to
control exposures within guidelines of OSHA PEL: TWA 10 ppm and ACGIH TLV: TWA 10
ppm, STEL 15 ppm.
