| 화재 위험 | Special Hazards of Combustion Products: Dissociation products generated in a fire may be irritating or toxic. (USCG, 1999)· Some of these materials may burn, but none ignite readily.Not combustible. Gives off irritating or toxic fumes (or gases) in a fire. Heating will cause rise in pressure with risk of bursting. Risk of fire and explosion. See Chemical Dangers. |

| 유해성 요약 | In laboratory studies, animals experienced CNS depression at 2400-2800 ppm and liver and kidney damage after repeated exposures to 1000 ppm. [CHEMINFO] Dichloromethane seldom causes hepatotoxicity unless exposure is very heavy or agent ingested. [Zimmerman, p. 333] If left on clothes, may cause reddening of skin[CHRIS] May have effects on nervous system and blood, causing impaired functions, carboxyhemoglobinemia, and lowering of consciousness |
