First Aid MeasuresBack to Contents
【Ingestion】

Induce vomiting immediately as directed by medical personnel. Never give anything by mouth to an unconscious person.
【Inhalation】

Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. DO NOT use mouth-to-mouth respiration.
【Skin】

Immediately flush skin with plenty of water for at least 15 minutes. Remove contaminated clothing and shoes. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention if irritation develops.
【Eyes】

Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
Handling and StorageBack to Contents
【Storage】

Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.
【Handling】

Wash thoroughly after handling. Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation.
Hazards IdentificationBack to Contents
【Inhalation】

Large oral dose may produce symptoms of narcosis, incoordination, and kidney damage.
【Skin】

No adverse health effects expected. Prolonged contact may cause slight irritation.
【Eyes】

May cause mild irritation, possible reddening.
【Ingestion】

A nonvolatile liquid - vapor inhalation is unlikely. Inhalation of high vapor concentrations may cause respiratory tract irritation and have a narcotic effect with symptoms of drunkenness.
【Hazards】

When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards.

【Flash Point】

121
【Autoignition】

350
【Fire Fighting】

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Containers may explode when heated. To extinguish fire use water spray, dry chemical, carbon dioxide, or chemical foam. Water spray may cause frothing. Cool containers with flooding quantities of water until well after fire is out.

15.3
【Lower exp. limit】

2.4
【Fire Potential】

Low fire hazard, when exposed to heat or flame. Not considered to be an explosion hazard.
Accidental Release MeasuresBack to Contents
【Small spills/leaks】

Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, using the appropriate protective equipment. Remove all sources of ignition. Provide ventilation.
