Hazards and Protection.
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
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.
Protective gloves and clothing. Face shield or eye protection in combination with breathing proteciton if a powder.
Wear positive pressure self-contained breathing apparatus (SCBA).
Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Cover with plastic sheet to prevent spreading. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS.
Active ingredient is unstable in strongly alkaline media.
When heated to decomposition it emits toxic fumes of nitrogen oxides.
Use method most appropriate to fight surrounding fire.
Fire may produce irritating, corrosive and/or toxic gases.
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.
Nausea, vomiting, diarrhea, and abdominal cramping have been reported and are common.
Dyspnea, wheezing, rales, increased bronchial secretions, respiratory muscle weakness and respiratory failure may occur. Usual cause of death is respiratory failure.
A possible occupational effect is contact dermatitis. Diaphoresis may be seen after exposure. Cellulitis was seen after injection of household spray.
Constriction of the pupil and blurred vision are common. Mydriasis may occur.
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.
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.
Remove contaminated clothing and jewelry. Wash the skin, including hair and nails, vigorously; do repeated soap washings. Discard contaminated clothing.
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.
