UN 2762 Quick Details
UN 2762
Product name: Organochlorine pesticide, liquid, flammable, poisonous
DOT Class: 3
Placard type: Flammable
ERG Guide: 131 (check current ERG)
Initial 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
Common Hazards of UN 2762
- 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.
Chemical Identity & Physical Properties
| 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 |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Fireground Response Guidance — UN 2762
Extinguishing Media
Alcohol-resistant foam, CO2, dry chemical, water spray for cooling; avoid direct water streams on large spills
PPE Requirements
⚠️ 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 & Evacuation
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
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 131).
First Actions for a UN 2762 Incident
- 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
