Hazard data
Fire
| Extinguishing data | Use water spray, dry chemical, foam or carbon dioxide. (Note: fire residues may contain chlorinated furans or dioxins and must be treated as contaminated.) Use water to cool fire-exposed containers. Consult your fire department for proper equipment at your facility. |
| Fire behaviour | When heated to decomposition, toxic fumes of hydrogen chloride are formed. Chlorinated dioxins may be generated. |
| Ignition temperature | Not combustible |
| Burning rate | Not combustible |
Reactivity
| With water | No reaction |
| With common materials | Can cause deterioration of rubber when dissolved in oil. |
| Stability | Stable |
