| 輸送ラベル（DOT） | Poison |
| 火災危険 | (Non-Specific -- Insecticide, Liquid, Poisonous, n.o.s.) Highly toxic fumes are given off upon decomposition with heat. Container may explode in heat of fire. Decomposes rapidly in the presence of chlorine. Oxidizes slowly in strong oxidizing agents. (EPA, 1998) |
| 健康有害性 | This material is extremely toxicthe probable oral lethal dose (human) is 5-50 mg/kg, or 7 drops to 1 teaspoonful for a 150-lb. person. Death may occur from respiratory arrest. Hazards of vapor toxicity are high. (EPA, 1998) |
| 有害性の概要 | Very toxic cholinesterase inhibitor[Merck Index] The average of two baseline respective cholinesterase activity determinations three days apart, with no exposures to enzyme inhibiting pesticides for at least 30 days, is recommended for each worker prior to exposure to cholinesterase inhibitors because of large inter-individual differences in published baseline values. To be established at least once a year. Removal from workplace exposures is recommended until the cholinesterase activity returns to within 20% of baseline. [TLVs and BEIs] |
| 反応性グループ | Amines, Phosphines, and Pyridines |
| Reactivity Profile | Highly toxic fumes are given off upon decomposition of DIMEFOX with heat. Container may explode in heat of fire. Decomposes rapidly in the presence of chlorine. Oxidizes slowly in strong oxidizing agents. [EPA, 1998]. Organophosphates are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides. |
| Air and Water Reactions | No rapid reaction with air. No rapid reaction with water. |
| Other Hazardous Reactions | A portion of even the most flammable materials is likely to be lost by vaporization. ... The smoke from an open fire used to destroy pesticides will contain some of the poison. Burning should be attempted only in an isolated place. Inhalation of smoke must be avoided. /Pesticides/ |
