| Water Reactivity | Generally no significant reaction with water, though some formulations may dissolve or hydrolyze |
| Extinguishing | Water spray, dry chemical, CO2, or foam depending on formulation; avoid methods that create dust clouds |
| PPE | ⚠️ Level B minimum required; SCBA mandatory; chemical-resistant suit, gloves, and boots; avoid any skin contact due to high toxicity via absorption |

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
