Flash Point Method: PMCC
1
Flammability Classification: Non-Flammable
0
2
Extinguishing Media: Foam, Dry Chemical, and Carbon Dioxide --
Unusual Fire or Explosion Hazards: None
Hazardous Combustion Products: Oxides of Nitrogen and Carbon, Acids and Aldehydes when
burned
Fire-Fighting Instructions: Do not release runoff from fire control methods to sewers or
waterways.
Fire-Fighting Equipment: Because fire may produce toxic thermal decomposition products, wear
a self-contained breathing apparatus (SCBA) with a full face piece operated in pressure-demand
or positive-pressure mode.
Section 6 - Accidental Release Measures
Spill /Leak Procedures
Containment: Dike far ahead of liquid spill for later disposal. Do not release into sewers or
waterways.
Cleanup: Absorb with Vermiculite and scrape up excess.
Regulatory Requirements: Follow applicable OSHA regulations (29 CFR 1910.120).
Section 7 - Handling and Storage
Handling Precautions: Avoid prolonged or repeated skin contact. Use good general
housekeeping procedures.
Storage Requirements: Store in Closed containers. Use only with adequate ventilation.
Section 8 - Exposure Controls / Personal Protection
Engineering Controls:
Ventilation: Provide general or local exhaust ventilation systems to maintain airborne
concentrations below OSHA PELs (Sec. 2). Local exhaust ventilation is preferred because it
prevents contaminant dispersion into the work area by controlling it at its source.
Administrative Controls:
Respiratory Protection: Seek professional advice prior to respirator selection and use. Follow
OSHA respirator regulations (29 CFR 1910.134) and, if necessary, wear an MSHA/NIOSH-
approved respirator. Select respirator based on its suitability to provide adequate worker
protection for given working conditions, level of airborne contamination, and presence of
sufficient oxygen. For emergency or nonroutine operations (cleaning spills, reactor vessels, or
storage tanks), wear an SCBA. Warning! Air-purifying respirators do not protect workers in
oxygen-deficient atmospheres. If respirators are used, OSHA requires a written respiratory
protection program that includes at least: medical certification, training, fit testing, periodic
environmental monitoring, maintenance, inspection, cleaning, and convenient, sanitary storage
areas.
Protective Clothing/Equipment: Wear chemically protective gloves, boots, and aprons to prevent
prolonged or repeated skin contact. Wear protective eyeglasses or chemical safety goggles, per
OSHA eye- and face-protection regulations (29 CFR 1910.133). Contact lenses are not eye
protective devices. Appropriate eye protection must be worn instead of, or in conjunction with
contact lenses.

Section 8 - Exposure Controls / Personal Protection (continued)
Safety Stations: Make emergency eyewash stations, safety/quick-drench showers, and washing
facilities available in work area.
Contaminated Equipment: Separate contaminated work clothes from street clothes. Launder
before reuse. Remove this material from your shoes and clean personal protective equipment.
Comments: Never eat, drink, or smoke in work areas. Practice good personal hygiene after using
this material, especially before eating, drinking, smoking, using the toilet, or applying cosmetics.
