Chemical & Response Details
| Also known as | Phenylurea herbicidesSubstituted urea pesticidesDiuron-type herbicidesMonuron pesticidesLinuron pesticides |
| Appearance | Varies by formulation; typically clear to pale yellow liquid with mild to no odor. Solutions or emulsifiable concentrates of substituted phenylurea compounds used as herbicides. |
| Flash Point | Varies by formulation and carrier solvent; typically 23-61C (73-142F) for petroleum-based formulations |
| Boiling Point | Varies by formulation; carrier solvents typically 150-300C (302-572F) |
| Vapor Density | Heavier than air; typically 3-6 depending on carrier solvent |
| Water Reactivity | No significant reaction; may disperse or emulsify depending on formulation |
| Extinguishing | Alcohol-resistant foam preferred; CO2, dry chemical, water spray for cooling containers |
| PPE | ⚠️ Level B minimum with SCBA; Level A if concentrated material or enclosed space. Chemical-resistant suit and gloves required. Avoid all skin contact due to absorption hazard. |
| Isolation | ERG 151: Isolate spill 25-50m all directions. If tank/rail car involved in fire, isolate 800m all directions and consider initial evacuation 800m. |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Common hazards (high level)
- Highly toxic, may be fatal if inhaled, ingested or absorbed through skin.
- Avoid any skin contact.
- Fire may produce irritating, corrosive and/or toxic gases.
- Runoff from fire control or dilution water may be corrosive and/or toxic and cause environmental
- Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive
- Containers may explode when heated.
- Runoff may pollute waterways.
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.
- Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters
- 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
