Hazards and Protection.
Storage
Store in a cool, dry place. Keep container closed when not in use.
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 safety goggles and appropriate protective gloves and clothing.
Respirators
Wear a NIOSH/MSHA or European Standard EN 149 approved full-facepiece airline respirator in the positive pressure mode with emergency escape provisions.
Small spills/leaks
Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Clean up spills immediately, using the appropriate protective equipment.
Stability
Stable under normal temperatures and pressures.
Incompatibilities
Strong oxidizing agents, strong bases.
Decomposition
Carbon monoxide, irritating and toxic fumes and gases, carbon dioxide, hydrogen bromide.

Fire.
Flash Point,°C
81
Fire fighting
Wear a self-contained breathing apparatus inpressure-demand, MSHA/NIOSH (approved or equivalent), and fullprotective gear. During a fire, irritating and highly toxic gasesmay be generated by thermal decomposition or combustion. In case of fire, use water, dry chemical, chemical foam, oralcohol-resistant foam.
Fire potential
Moderate fire hazard, when exposed to heat or flame.

Health.
Exposure effects
Agitation and syncope, both attributed to panic, have been reported.
   Ingestion
A metallic taste with a burning sensation of the tongue is common. Nausea is common; vomiting occurs occasionally. Epigastric discomfort and burping may occur if tear gas is swallowed.
   Inhalation
Cough, rhinorrhea, sneezing, chest tightness, and laryngospasm may occur shortly following exposure due to the irritant effects.
   Skin
Irritation may occur to all body surfaces where significant exposure has occurred. Painful contact dermatitis may persist for several hours following exposure to mace containing capsaicin. Bullous dermatitis may develop 12 to three days after exposure to tear gas containing o-chlorobenzylidene malononitrile (cs). Erythema, vesicle eruptions, and denuded areas with weeping tender erythematous base may develop one day after exposure to mace containing 1-chloroacetophenone (cn).

First aid
 
   Ingestion
Do NOT induce vomiting. Allow the victim to rinse his mouth and then to drink 2-4 cupfuls of water, and seek medical advice.
   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. Remove all contaminated clothing while avoiding self-contamination. Meticulously wash all exposed areas with copious amounts of soap and water. The patient's clothing may contain residual particles from the exposure and clothing should be removed and stored in a sealed polythene bag to prevent degassing. If clothing is to be washed, cold water should be used because hot wat will cause residual o-chlorobenzylidene malononitrile (cs) gas to vaporize.
   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.
