Section 5 - Fire-Fighting Measures
Flash Point: 69.8 癋 (21 癈)
Flash Point Method: N/a.
Burning Rate: N/a.
Autoignition Temperature: N/a.
LEL: N/a.
UEL: N/a.
Flammability Classification: Flammable.
Extinguishing Media: Dry chemical, carbon dioxide.
Unusual Fire or Explosion Hazards: None established.
Hazardous Combustion Products: Carbon monoxide, carbon dioxide.
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 facepiece operated in pressure-demand or positive-pressure mode.
Section 6 - Accidental Release Measures
Spill /Leak Procedures:
Small Spills: Cover with absorbent, pick up, and place in a suitable container.
Large Spills
Containment: For large spills, dike far ahead of liquid spill for later disposal. Do not release into sewers or waterways.
Cleanup: Follow all applicable local, state, and federal regulations during decon.
Regulatory Requirements: Follow all applicable local, state, and federal regulations.
Section 7 - Handling and Storage
Handling Precautions: Wear all appropriate personal protective equipment.
Storage Requirements: Store material in D.O.T. approved containers. Vapors can travel considerable distances to reach a source
of ignition and flash back.
Regulatory Requirements: Follow all applicable local, state, and federal regulations.
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 a 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.
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, aprons, and gauntlets 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.
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.
