Hazards and Protection.
Storage
Keep containers tightly closed. Keep away from heat and open flame. Store at away from dwellings. Do not contaminate food or foodstuffs. Do not store or use the mixture in containers made of aluminum, magnesium, or their alloys.
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 chemical protective gloves, boots, and goggles. Rubber gloves, self-contained breathing apparatus, coveralls or laboratory coat.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Neutralizing Agents for Acids and Caustics: Sodium bicarbonate or sand and soda ash mixture.
Stability
Containers may explode in heat of fire. Vapor explosion hazard indoors, outdoors, or in sewers. Runoff to sewer may be a fire or explosion hazard.
Incompatibilities
Can react with some metals to form dangerous products Incompatible with strong oxidizing and reducing agents Incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides Can react with aluminum, magnesium and their alloys.

Fire.
Fire fighting
Fire Extinguishing Agents: Small fires: dry chemicals, CO 2 , water spray or foam; large fires: water spray, fog or foam.
Fire potential
Flammable. Will burn and can be ignited by heat, sparks, and flames. Flammable vapors may spread away from fire. Runoff to sewers may be a fire or explosion hazard.
Hazards
Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers.
Combustion products
Smoke contains hydrogen chloride and it may contain phosgene; both components are highly toxic gases.

Health.
Exposure effects
Very high concentrations are depressant in animals.
   Ingestion
ARDS has been reported after ingestion. Animals exposed to 2700 ppm developed severe lung injury.
   Inhalation
Ards has been reported after ingestion. Animals exposed to 2700 ppm developed severe lung injury.
   Skin
Necrosis and edema were present when the agent was confined to rabbit skin, but were much reduced when the product was allowed to evaporate.
   Eyes
See Skin.

First aid
 
   Ingestion
Administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents. Monitor liver and kidney function. Elevations may not be seen for several days. Respiratory support may be indicated in significant exposures. Monitor for pulmonary edema. 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 victim to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, pneumonitis or bronchits. Administer oxygen and assist ventilation as required.
   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.
