Placard type: Flammable
ERG: Guide 131 (check current ERG)
Isolation: ERG 131: Isolate spill/leak area minimum 50m (150 ft) all directions; if tank/rail car involved in fire, isolate 800m (0.5 mile) radius and consider evacuation
Chemical & Response Details
| Also known as | carbamate insecticidecarbamate pesticide solutionflammable carbamate pesticideliquid carbamate |
| Appearance | Liquid formulation of carbamate pesticide, typically amber to dark brown in color with characteristic pesticide odor. Physical properties vary by specific active ingredient and carrier solvent. |
| Flash Point | Below 23C (73F) - Class 3 flammable liquid |
| Boiling Point | Varies by formulation and carrier solvent, typically 80-150C (176-302F) |
| Vapor Density | Greater than 1 (heavier than air) - vapors accumulate in low areas |
| Water Reactivity | No violent reaction with water, but may hydrolyze slowly; water-miscible depending on formulation |
| Extinguishing | Alcohol-resistant foam (AR-AFFF), CO2, dry chemical; water spray for cooling only |
| PPE | ⚠️ Level B minimum with SCBA required; chemical-resistant suit and gloves; avoid all skin contact due to absorption hazard |
| Isolation | ERG 131: Isolate spill/leak area minimum 50m (150 ft) all directions; if tank/rail car involved in fire, isolate 800m (0.5 mile) radius 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
