Hazards and Protection.
Storage
Store in a cool, dry place. Store in a tightly closed container.
Handling
Avoid breathing dust, vapor, mist, or gas. Avoid contact with skin and eyes.
Protection
Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.
Respirators
Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.
Small spills/leaks
Vacuum or sweep up material and place into a suitable disposal container.
Stability
Stable under normal temperatures and pressures.
Incompatibilities
Strong oxidizing agents.
Decomposition
Carbon monoxide, carbon dioxide.

Fire.
Flash Point,°C
160
Fire fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. To extinguish fire use water spray, dry chemical, carbon dioxide, or chemical foam.
Fire potential
Flammable/combustible material. May be ignited by friction, heat, sparks or flames.
Combustion products
Fire may produce irritating and/or toxic gases.

Health.
Exposure effects
Mild central nervous system depression or excitation may occur after ingestion or vapor inhalation. CNS effects can occur secondary to hydrocarbon pneumonitis and hypoxia, or from additives and contaminants (aniline, heavy metals, camphor, or pesticides). Some hydrocarbons are simple asphyxiants (e.G., Methane, ethane, propane gasses) which can produce CNS effects secondary to hypoxia. In a prospective study in Toronto, major congenital malformations were noted in 13 of 125 fetuses of mothers exposed to organic solvents during pregnancy.
   Ingestion
May cause irritation of the digestive tract. May be harmful if swallowed.
   Inhalation
May cause respiratory tract irritation. May be harmful if inhaled.
   Skin
May cause skin irritation. May be harmful if absorbed through the skin.
   Eyes
May cause eye irritation.

First aid
 
   Ingestion
Get medical aid. Wash mouth out with water.
   Inhalation
Remove from exposure to fresh air immediately.
   Skin
Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
   Eyes
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
