Fire Fighting Measures: Self-contained breathing apparatus and protective clothing should be worn in 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 Hazards: None.
6. ACCIDENTAL RELEASE MEASURES
Containment/Clean up: Observe all personal protection equipment recommendations described in Sections 5 and 8.
Wipe up or scrape up and contain for salvage or disposal. Clean area as appropriate since
spilled materials, even in small quantities, may present a slip hazard. Final cleaning may
require use of steam, solvents or detergents. Dispose of saturated absorbant 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. You will need to determine which federal,
state and local laws and regulations are applicable. Sections 13 and 15 of this MSDS provide
information regarding certain federal and state requirements.
Note: See Section 8 for Personal Protective Equipment for Spills.
7. HANDLING AND STORAGE
Use with adequate ventilation. Product evolves acetic acid (HOAc) when exposed to water or humid air. Provide ventilation
during use to control HOAc within exposure guidelines or use respiratory protection. Avoid eye contact. Avoid skin contact.
Avoid breathing vapor. Keep container closed. Do not take internally.
Use reasonable care and store away from oxidizing materials. Keep container closed and store away from water or moisture.
This material in its finely divided form presents an explosion hazard. Follow NFPA 654 (for chemical dusts) or 484 (for metal
dusts) as appropriate for managing dust hazards to minimize secondary explosion potential.
