Hazards and Protection.
Storage
Isolate from combustibles, sulfur, carbonaceous materials, finely divided metals, organic, oxidizable materials, mineral acids.
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 eye goggles, protective clothing and self-contained breathing apparatus. Equipment should be resistant to oxidation.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Keep sparks, flames, and other sources of ignition away. Keep spilled material wet. Wet spilled material before picking it up. Do not attempt to sweep up dry material. Keep material out of water sources and sewers.
Stability
No data.

Fire.
Autoignition, °C
240
Fire fighting
Dangerously explosive. Do not fight fires in a cargo of explosives. Evacuate area and let burn.
Fire potential
Slightly flammable. Moderate when exposed to heat or flame. Combustion products are toxic.
Hazards
May ignite combustibles (wood, paper, oil, clothing, etc.). Some will react explosively with hydrocarbons (fuels).
Combustion products
Toxic gases are produced in a fire.

Health.
Exposure effects
   Ingestion
Esophageal or gastrointestinal tract irritation could occur following exposures.
   Inhalation
Respiratory tract irritation or pulmonary edema may occur.
   Skin
Dermal irritation may be noted.
   Eyes
See Inhalation.

First aid
 
   Ingestion
Emesis: ipecac-induced vomiting is not recommended because there is so little information about the effects of overdose in humans. Following ingestion and/or prior to gastric evacuation, immediately dilute with 4 to 8 ounces (120 to 240 ml) of milk or water (not to exceed 15 ml/kg in a child). Consider after ingestion of a potentially life-threatening amount of poison if it can be performed soon after ingestion (generally within 1 hour). Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents. Observe patients with ingestion carefully for the possible development of esophageal or gastrointestinal tract irritation or burns. If signs or symptoms of esophageal irritation or burns are present, consider endoscopy to determine the extent of injury.
   Inhalation
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult.
   Skin
Remove and isolate contaminated clothing and shoes. Immediately flush skin or eyes with running water for at least 20 minutes.
   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.
