Response Recommendations

Isolation and Evacuation

Excerpt from 152

[Substances - Toxic (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

Fire Extinguishing Agents: Water, CO2, dry chemical (USCG, 1999)

Non-Fire Response

Excerpt from 152

[Substances - Toxic (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. Cover with plastic sheet to prevent spreading. 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

Safety glasses with side shield or safety goggles and plastic face shield. Self-contained breathing apparatus or air line mask. Butyl rubber gloves, boots and protective clothing. (USCG, 1999)

First Aid

Call a doctor.

INHALATION: Remove from exposure. If cyanotic, oxygen can be administered.

EYES: Flush with copious amounts of water.

SKIN: Remove all contaminated clothing. Wash with lukewarm water and soap.

INGESTION: Induce vomiting. Administer gastric lavage. (USCG, 1999)
