【Handling】

Use only in a well ventilated area. Use spark-proof tools and explosion proof equipment. Do not breathe dust, vapor, mist, or gas. Do not get in eyes, on skin, or on clothing. Take precautionary measures against static discharges. Do not allow contact with water. Use only in a chemical fume hood.
Hazards IdentificationBack to Contents
【Ingestion】

Harmful if swallowed. May cause headache. May cause nausea and vomiting.
【Inhalation】

May be fatal if inhaled. Causes respiratory tract irritation. Inhalation may be fatal as a result of spasm, inflammation, edema of the larynx and bronchi, chemical pneumonitis and pulmonary edema. May cause an allergic response.
【Skin】

Causes skin irritation.
【Eyes】

Causes eye irritation. Lachrymator. Lachrymator.
【Hazards】

Vapors form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapors may travel to source of ignition and flash back. Substance will react with water (some violently) releasing flammable, toxic or corrosive gases and runoff. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water.

Fire Fighting MeasuresBack to Contents
【Flash Point】

0
【Fire Fighting】

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Can burn in a fire, releasing toxic vapors. Will burn if involved in a fire. Water Reactive. Material will react with water and may release a flammable and/or toxic gas. Wear appropriate protective clothing to prevent contact with skin and eyes. Wear a self-contained breathing apparatus (SCBA) to prevent contact with thermal decomposition products. Extinguishing media: Do NOT use alcohol foams. If water is the only media available, use in flooding amounts. Use carbon dioxide or dry chemical.
【Fire Potential】

HIGHLY FLAMMABLE.
