General Description
A straw-colored liquid. Denser than water. Contact may cause severe irritation to skin, eyes, and mucous membranes. May be toxic by ingestion.

Hazards

Reactivity Alerts
Air & Water Reactions
Fumes in air.
Fire Hazard
Special Hazards of Combustion Products: At elevated temperatures, the material will decompose, producing hydrogen chloride. (USCG, 1999)
Health Hazard
The material is corrosive and contact with the skin, eyes or respiratory tract may cause sever skin irritation and burns. (USCG, 1999)
Reactivity Profile
ALUMINUM CHLORIDE, SOLUTION is an aqueous solution of an acidic salt. Reacts exothermically with bases. May cause ethylene (also other alkenes) to polymerize violently [J. Inst. Pet. 33:254 1947].
Belongs to the Following Reactive Group(s)
Potentially Incompatible Absorbents

Use caution: Liquids with this reactive group classification have been known to react with the absorbents listed below.

Response Recommendations

Isolation and Evacuation
Excerpt from 154 Polymerizable warning [Substances - Toxic and/or Corrosive (Non-Combustible)]:

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)
Firefighting
Excerpt from 154 Polymerizable warning [Substances - Toxic and/or Corrosive (Non-Combustible)]:

SMALL FIRE: Dry chemical, CO2 or water spray.

LARGE FIRE: Dry chemical, CO2, alcohol-resistant foam or water spray. If it can be done safely, move undamaged containers away from the area around the fire. Dike runoff from fire control for later disposal.

FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles. Do not get water inside containers. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. (ERG, 2020)
Non-Fire Response
Excerpt from 154 Polymerizable warning [Substances - Toxic and/or Corrosive (Non-Combustible)]:

ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS. (ERG, 2020)
Protective Clothing
Wear impervious protective clothing and gloves to prevent skin contact. Wear splashproof chemical safety goggles and approved respirator. (USCG, 1999)

First Aid
Call for medical aid.

INGESTION: If victim is conscious have him drink water or milk.

SKIN: Flush immediately with plenty of water.

EYES: Flush with water for at least 15 mins., lifting lids occasionally. (USCG, 1999)
