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.
Wear appropriate protective gloves, clothing and goggles.
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.
Stable to light and at temperature < 90 C. Rapidly hydrolyzed in alkaline media. Relatively stable to neutral and weakly acidic aqueous solutions. Stable to light and to temperatures up to 90 C.
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.
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 patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.
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.
