FLASH POINT：84°C (183.2°F)
EXTINGUISHING MEDIA：Use dry powder or carbon dioxide when fighting a fire involving this material. Water extinguishers are not recommended.
GENERAL INFORMATION：As in any fire, wear self-contained breathing apparatus pressure-demand, niosh(approved or equivalent) and full protective gear.
SECTION 6. ACCIDENTAL RELEASE MEASURES
Use proper personal protective equipment as indicated in Section 8.
SPILLS AND LEAKS: Clean up spills immediately, observing precautions in the protective equipment section. Absorb spill with dry inert material, such as dry san, earth, or vermiculite, then place in suitable container. Refer to Section 13 for proper disposal.
ENVIRONMENTAL PRECAUTIONS: Do not allow material to enter drains or streams.
SECTION 7. HANDLING AND STORAGE
HANDLING：
This product should be handled only by, or under the close supervision of, those properly qualified in the handling and use of potentially hazardous chemicals, who should take into account the fire, health and chemical hazard data. It should always be handled in an efficient fume hood or equivalent system. The user should consider that the toxicological and physicological properties of many compounds are not yet well determined and that new hazardous products may arise from reactions between chemicals. Care should be taken to prevent any chemical from coming into contact with the skin or eyes and from contaminating personal clothing.
STORAGE：
Store in a cold, below 5 degrees celcius, dry, well ventilated area away from source of heat and incompatible substances. Keep container tightly closed and cold when not in use. Product is moisture sensitive.
HYGIENE PRACTICES：
Wash thoroughly after handling. Avoid contact with eys and skin. Avoid inhaling dust, vapor, or mist.
SECTION 8. EXPOSURE CONTROLS/PERSONAL PROTECTION
ENGINEERING CONTROLS：
Use appropriate engineering control such as process enclosures, local exhaust ventilation, or other engineering controls to control airborne levels below recommended exposre limits. Where such systems are not effective sear suitable personal protective equipment, which performs satisfactorily and meets OSHA or other recognized standards. Consult with local procedures for selection, training, inspection and maintenance of the personal protective equipment.
EYES：Wear appropriate protective glasses or splash goggles as described by 29 CFR 1910.133, OSHA eye and face protection regulation, or the European standards EN 166.
SKIN AND CLOTHING：Wear suitable protective clothing to prevent contact with skin. Wear appropriate protective gloves. Consult glove manufactures for glove permeability data.
RESPIRATORS：A NIOSH approved air-purifying respirator with an appropriate cartridge or canister may be permissible under certain circumstances where airborne concentrations are expected to exceed exposure limits. Protection provided by air purifying respirators is limited to airborne concentrations that are typically within 10 times the exposure limit. Use a positive pressure air supplied respirator if there is any potential for an uncontrolled release, exposure levels are not known, or any other circumstances where air-purifying respirators may not provide adequate protection. A respiratory protection program that meets OSHAS 29 CFR 1910.134 and ANSI Z88.2 requirements must be followed whenever workplace conditions warrant a respirators use.
OTHER PROTECTIVE：
Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower.
