Chemical & Response Details
| Also known as | Copper fungicide solutionCupric pesticide liquidCopper-based agricultural chemicalFlammable copper pesticide formulation |
| Appearance | Liquid pesticide formulation, typically blue-green to dark green color due to copper compounds. May have a mild chemical or metallic odor. Liquid state at room temperature, flammable. |

| Vapor Density | Heavier than air, typically 2-4 relative to air |
| Water Reactivity | No significant violent reaction with water, but may form toxic runoff |
| Extinguishing | Alcohol-resistant foam (AR-AFFF), dry chemical, CO2 suitable; avoid high-volume water spray |
| PPE | ⚠️ Level B minimum for liquid contact; SCBA required in fire or confined spaces; chemical-resistant suit, gloves, and eye protection mandatory due to dermal absorption hazard |

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
