General Description
2,4,5-Trichlorophenoxyacetic acid ester, are various colored solids. They are soluble in water. The primary hazard is the threat posed to the environment. Immediate steps should be taken to limit its spread to the environment. They will burn though they may take some effort to ignite. They are used as herbicides, defoliants, or plant growth regulators.
Hazards
Reactivity Alerts
none
Air & Water Reactions
Water soluble.
Fire Hazard
Special Hazards of Combustion Products: Hydrogen chloride gas and other irritating fumes may form in fires. (USCG, 1999)
Health Hazard
Ingestion causes intestinal disturbances. Contact with eyes or skin causes mild irritation; transient corneal injury may occur. (USCG, 1999)
Reactivity Profile
Reacts with hypochlorites to give N-chloroamines, some of which are explosives when isolated [Bretherick 1979. p. 108].
Belongs to the Following Reactive Group(s)
- Esters, Sulfate Esters, Phosphate Esters, Thiophosphate Esters, and Borate Esters
- Salts, Basic
- Aryl Halides

Response Recommendations
Isolation and Evacuation
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)
Firefighting
Excerpt from 171
[Substances (Low to Moderate Hazard)]:
SMALL FIRE: Dry chemical, CO2, water spray or regular foam.
LARGE FIRE: Water spray, fog or regular foam. Do not scatter spilled material with high-pressure water streams. 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: 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 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)
Protective Clothing
Goggles or face shield and rubber gloves (USCG, 1999)

First Aid
INGESTION: promptly induce vomiting and get medical attention.
EYES: flush with flowing water and get medical attention.
SKIN: wash with soap and water. (USCG, 1999)
