Hazards and Protection.
Isolate from combustibles, sulfur, carbonaceous materials, finely divided metals, organic, oxidizable materials, mineral acids.
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.
Wear eye goggles, protective clothing and self-contained breathing apparatus. Equipment should be resistant to oxidation.
Wear positive pressure self-contained breathing apparatus (SCBA).
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.
Dangerously explosive. Do not fight fires in a cargo of explosives. Evacuate area and let burn.
Slightly flammable. Moderate when exposed to heat or flame. Combustion products are toxic.
May ignite combustibles (wood, paper, oil, clothing, etc.). Some will react explosively with hydrocarbons (fuels).
Toxic gases are produced in a fire.
Esophageal or gastrointestinal tract irritation could occur following exposures.
Respiratory tract irritation or pulmonary edema may occur.
Dermal irritation may be noted.
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.
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult.
Remove and isolate contaminated clothing and shoes. Immediately flush skin or eyes with running water for at least 20 minutes.
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.
