data sources.
Reactivity Alerts
- Strong Reducing Agent
- Water-Reactive
- Pyrophoric
Air & Water Reactions
Highly flammable. Ignites when exposed to air. Reacts violently with water or moisture in air forming hydrogen chloride fumes and flammable ethane gas (Rose 1961).
Fire Hazard
Special Hazards of Combustion Products: Intense smoke may cause metal-fume fever. Irritating hydrogen chloride also formed.
Behavior in Fire: Contact with water applied to adjacent fires will cause formation of irritating smoke containing aluminum oxide and hydrogen chloride. (USCG, 1999)
Behavior in Fire: Contact with water applied to adjacent fires will cause formation of irritating smoke containing aluminum oxide and hydrogen chloride. (USCG, 1999)
Health Hazard
Inhalation of smoke from fire causes metal-fume fever (flu-like symptoms); acid fumes irritate nose and throat. Contact with liquid (which is spontaneously flammable) causes severe burns of eyes and skin. (USCG, 1999)
Reactivity Profile
Organometallics, such as ETHYL ALUMINUM DICHLORIDE, are reactive with many other groups. Incompatible with acids and bases. Organometallics are good reducing agents and therefore incompatible with oxidizing agents. Often reactive with water to generate toxic or flammable gases. Organometallics containing halogens (fluorine, chlorine, bromine, iodine) bonded to the metal typically with generate gaseous hydrohalic acids (HF, HCl, HBr, HI) with water.
Belongs to the Following Reactive Group(s)
Potentially Incompatible Absorbents

Response Recommendations
The
Response Recommendation fields
include isolation and evacuation distances, as well as recommendations for
firefighting, non-fire response, protective clothing, and first aid. The
information in CAMEO Chemicals comes from a variety of
data sources.
Isolation and Evacuation
Excerpt from ERG Guide 135 [Substances - Spontaneously 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 tank car or highway tank 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, 2024)

FIRE: If tank, rail tank car or highway tank 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, 2024)
Firefighting
Fire Extinguishing Agents Not to Be Used: Water, foam, dry chemicals, halogenated agents, or carbon dioxide
Fire Extinguishing Agents: Inert dry powders such as dry graphite, soda ash, sand, limestone. (USCG, 1999)
Fire Extinguishing Agents: Inert dry powders such as dry graphite, soda ash, sand, limestone. (USCG, 1999)
Non-Fire Response
Neutralizing Agents for Acids and Caustics: Rinse with sodium bicarbonate or lime solution. (USCG, 1999)
Protective Clothing
Full protective clothing, preferably of aluminized glass cloth; goggles, face shield, gloves; in case of fire, all-purpose canister or self-contained breathing apparatus. (USCG, 1999)
DuPont Tychem® Suit Fabrics
No information available.
First Aid
INHALATION: only fumes from fire need be considered; metal-fume fever is not critical and lasts less than 36 hrs.; irritation of nose and throat by acid vapors may require treatment by a physician.
EYES: flush gently with water for 15 min.; treat burns if fire occurred; get medical attention.
SKIN: wash with water; treat burns caused by fire; get medical attention. (USCG, 1999)

SKIN: wash with water; treat burns caused by fire; get medical attention. (USCG, 1999)
Physical Properties
The
Physical Property fields
include properties such as vapor pressure and
boiling point, as well as explosive limits and
toxic exposure thresholds
The information in CAMEO Chemicals comes from a variety of
data sources.
Note: For Vapor Density and Specific Gravity, comparing the value to 1.0 can tell you if the chemical will likely sink/rise in air or sink/float in fresh water (respectively). Short phrases have been added to those values below as an aid. However, make sure to also consider the circumstances of a release. The Vapor Density comparisons are only valid when the gas escaping is at the same temperature as the surrounding air itself. If the chemical is escaping from a container where it was pressurized or refrigerated, it may first escape and behave as a heavy gas and sink in the air (even if it has a Vapor Density value less than 1). Also, the Specific Gravity comparisons are for fresh water (density 1.0 g/mL). If your spill is in salt water (density about 1.027 g/mL), you need to adjust the point of comparison. There are some chemicals that will sink in fresh water and float in salt water.
