UN 2772
Class: 3
Placard type: Flammable
ERG: Guide 131 (check current ERG)
Isolation: ERG 131: Initial isolate 50m all directions; if tank/rail car involved in fire, isolate 800m all directions and consider evacuation
Chemical & Response Details
| Also known as | thiocarbamate pesticidescarbamothioic acid derivativesdithiocarbamate pesticidesthiocarbamate herbicides |
| Appearance | Liquid pesticide formulations, color varies by product (often amber to dark brown), may have mild to pungent odor depending on formulation and solvents used. |
| Flash Point | Typically 23-60°C (73-140°F), varies by formulation and solvent system |
| Boiling Point | Varies widely by formulation, typically 150-300°C (302-572°F) |
| Vapor Density | Greater than 1 (heavier than air), typically 3-6 times air density |
| Water Reactivity | No significant reaction with water, though some hydrolysis may occur; water-miscible to immiscible depending on formulation |
| Extinguishing | Alcohol-resistant AFFF foam, CO2, dry chemical powder; regular foam may not be effective on polar solvents |
| PPE | ⚠️ Level B minimum with SCBA required; full chemical-resistant suit, gloves, and boots; avoid all skin contact due to dermal toxicity |
| Isolation | ERG 131: Initial isolate 50m all directions; if tank/rail car involved in fire, isolate 800m all directions and consider evacuation |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Common hazards (high level)
- TOXIC; may be fatal if inhaled, ingested or absorbed through skin.
- Inhalation or contact with some of these materials will irritate or burn skin and eyes.
- Methyl chloroacetate (UN2295) is an eye irritant/lachrymator (causes flow of tears).
- Fire will produce irritating, corrosive and/or toxic gases.
- Vapors may cause dizziness or asphyxiation, especially when in closed or confined areas.
- Runoff from fire control or dilution water may cause environmental contamination.
- HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.
- Vapors may form explosive mixtures with air.
First actions (field-minded)
- CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper
- Keep unauthorized personnel away.
- Stay upwind, uphill and/or upstream.
- Ventilate closed spaces before entering, but only if properly trained and equipped.
- Isolate spill or leak area for at least 50 meters (150 feet) in all directions.
- For highlighted materials: see Table 1 - Initial Isolation and Protective Action Distances.
- For non-highlighted materials: increase the immediate precautionary measure distance, in the downwind
