UN 2762
Class: 3
Placard type: Flammable
ERG: Guide 131 (check current ERG)
Isolation: ERG 131: isolate spill area 50m (150 ft) in all directions; if tank/rail car involved in fire, isolate 800m (0.5 mi) in all directions and consider evacuation
Chemical & Response Details
| Also known as | Organochlorine pesticide solutionChlorinated hydrocarbon pesticideChlorinated organic pesticideFlammable organochlorine insecticide |
| Appearance | Liquid solution, color varies depending on specific formulation (typically amber to brown). May have mild to pungent chemical odor. Liquid at room temperature. |
| Flash Point | 23°C to 60°C (73°F to 140°F) depending on formulation and solvent |
| Boiling Point | Varies widely, typically 60°C to 150°C (140°F to 302°F) depending on solvent and active ingredient |
| Vapor Density | Greater than 1 (heavier than air), typically 3-6 times heavier than air |
| Water Reactivity | No significant reaction with water, but may be immiscible and form separate layers |
| Extinguishing | Alcohol-resistant foam, CO2, dry chemical, water spray for cooling; avoid direct water streams on large spills |
| PPE | ⚠️ Level B minimum for spill response; Level A if confined space or high concentrations; SCBA required; chemical-resistant suit, gloves, and boots mandatory due to severe skin absorption hazard |
| Isolation | ERG 131: isolate spill area 50m (150 ft) in all directions; if tank/rail car involved in fire, isolate 800m (0.5 mi) in 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
