| Hazards and Protection. | |
| Storage | Keep in well ventilated area. |
| Handling | All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood. |
| Protection | Wear appropriate protective gloves, clothing and goggles. |
| Respirators | Wear positive pressure self-contained breathing apparatus (SCBA). |
| Small spills/leaks | Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water. Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete. Water spill: Use natural barriers or oil spill control booms to limit spill travel. Use natural deep water pockets, excavated lagoons, or sand bag barriers to trap material at bottom. Remove trapped material with suction hoses. |
| Stability | Stable. |
| Incompatibilities | Incompatible with strong acids and bases, and especially |
| Decomposition | When heated to decomposition it emits toxic fumes of oxides of nitrogen. |

| Fire fighting | Fire Extinguishing Agents: Solution fires; Water, foam, dry chemical, CO 2 | |||
| Fire potential | Nonflammable. | |||
| Hazards | Containers may explode when heated. Runoff may pollute waterways. | |||
| Combustion products | Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. | |||
| Health. | |
| Exposure limit(s) | TLV: ppm; 5 mg/m3 (as TWA) (ACGIH 1993-1994). MAK: ppm; 5 mg/m3; (1992). OSHA PEL: TWA 5 mg/m3 NIOSH REL: TWA 5 mg/m3 NIOSH IDLH: 100 mg/m3 |
| Poison_Class | 3 |
| Exposure effects | In severe poisoning, respiratory depression, mental confusion, unconsciousness, brain hemorrhages, and seizures may occur. Children may be more susceptible to seizures than adults. Headache, blurred vision, tremor, paresis, mental depression, coma, delayed neuropathies, various dystonias, weakness, muscle twitching may be noted. |
| Ingestion | Nausea, vomiting, diarrhea, and abdominal cramping have been reported and are common. |
| Inhalation | Dyspnea, wheezing, rales, increased bronchial secretions, respiratory muscle weakness and respiratory failure may occur. Usual cause of death is respiratory failure. |
| Skin | A possible occupational effect is contact dermatitis. Diaphoresis may be seen after exposure. Cellulitis was seen after injection of household spray. |
| Eyes | Constriction of the pupil and blurred vision are common. Mydriasis may occur. |
First aid |
|
| Ingestion | Do not induce emesis. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents. |
| Inhalation | Move victim to fresh air. Apply artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. |
| Skin | Remove contaminated clothing and jewelry. Wash the skin, including hair and nails, vigorously; do repeated soap washings. Discard contaminated clothing. |
| Eyes | Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility. |
