DIISOPROPYLBENZENE (ALL ISOMERS)

Diamond	Hazard	Value	Description
2 1 0	Health	1	Can cause significant irritation.
	Flammability	2	Must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur.
	Instability	0	Normally stable, even under fire conditions.
	Special

Clear amber liquid with a sharp, penetrating odor. A mixture of three isomers (ortho, meta, and para).

none

Insoluble in water.

Special Hazards of Combustion Products: Vapors may travel considerable distance to an ignition source and flash back. (USCG, 1999)

Vapors and liquid are irritating to eyes, mucous membrane, and upper respiratory tract and can cause headache, narcosis and unconsciousness. Systemic effects can have a relatively long duration after exposure. Ingestion can be moderately to severely toxic. Liquid can cause defatting of skin and dermititis. (USCG, 1999)

Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as DIISOPROPYLBENZENE (ALL ISOMERS), and strong oxidizing agents. Can react exothermically with bases and with diazo compounds. Substitution at the benzene nucleus occurs by halogenation (acid catalyst), nitration, sulfonation, and the Friedel-Crafts reaction.

Excerpt from 171 [Substances (Low to Moderate Hazard)]:

IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.

SPILL: Increase the immediate precautionary measure distance, in the downwind direction, as necessary.

FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2020)

Fire Extinguishing Agents Not to Be Used: Water may be ineffective.

Fire Extinguishing Agents: Water spray, carbon dioxide, dry chemical, alcohol foam. (USCG, 1999)

Excerpt from 171 [Substances (Low to Moderate Hazard)]:

Do not touch or walk through spilled material. Stop leak if you can do it without risk. Prevent dust cloud. For Asbestos, avoid inhalation of dust. Cover spill with plastic sheet or tarp to minimize spreading. Do not clean up or dispose of, except under supervision of a specialist.

SMALL DRY SPILL: With clean shovel, place material into clean, dry container and cover loosely; move containers from spill area.

SMALL SPILL: Pick up with sand or other non-combustible absorbent material and place into containers for later disposal.

LARGE SPILL: Dike far ahead of liquid spill for later disposal. Cover powder spill with plastic sheet or tarp to minimize spreading. Prevent entry into waterways, sewers, basements or confined areas. (ERG, 2020)

Gloves impervious to aromatic hydrocarbon and splash-proof safety goggles. Approved organic cartridge respirator for exposure below 1,000 ppm. Full face piece is required above 500 ppm. Self-contained breathing apparatus or air supplied respirators above 1000 ppm. Clothing impervious to aromatic hydrocarbon. (USCG, 1999)

No information available.

INHALATION: Call for medical aid. Remove the victim to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.

INGESTION: Do not induce vomiting.

EYES: Flush with lots of running water for 15 minutes, lifting lower and upper lids occasionally.

SKIN: Wash with soap and water. Remove contaminated clothing. (USCG, 1999)
