Hazards and Protection.
Storage
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.
B3 D2B
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 eye protection and protective clothing to prevent skin and eye contact.
Respirators
Any self-contained breathing apparatus that has a full facepiece and is operated in a pressure-demand or other positive pressure mode. Any supplied-air respirator with a full face piece and operated in pressure-demand or other positive pressure mode in combination with an auxiliary self-contained breathing apparatus operated in pressure-demand or other positive pressure mode. Any appropriate escape-type, self-contained breathing apparatus.
Small spills/leaks
Make no contact with the spilled material. ELIMINATE all ignition sources and ground all equipment. Stop leak if you can do it without risk. A vapor suppressing foam may be used to reduce vapors. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. Use clean non-sparking tools to collect absorbed material.

Poison_Class
4
Exposure effects
Headache, dizziness, giddiness, ataxia, sedation and coma may occur.
   Ingestion
Nausea, vomiting, and diarrhea are common. Gastrointestinal hemorrhage can occur.
   Inhalation
Inhalation causes pulmonary tract irritation and rarely pulmonary edema. Severe respiratory depression or death has not been reported after inhalation.
   Skin
Dermatitis of varying severity may be noted. Drying and fissuring of the skin may be noted following chronic exposure.
   Eyes
See Skin.

First aid
 
   Ingestion
Treatment is symptomatic and supportive. Consider aspiration of gastric contents with a nasogastric tube after substantial recent (within 1 hour) ingestions. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents. Hypotension: infuse 10 to 20 ml/kg isotonic fluid, place in trendelenburg position. If hypotension persists, administer dopamine (5 to 20 mcg/kg/min) or norepinephrine (0.1 To 0.2 Mcg/kg/min), titrate to desired response.
   Inhalation
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.
   Skin
Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists.
   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.
