Hazards and Protection.
Storage Solutions should be stored in distinctive bottles (never in soft drink bottles) in safe place.
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 skin protection. If fire or intense heat prevail, wear self-contained breathing apparatus.
Respirators Use NIOSH/MSHA approved respirator appropriate for exposure of concern.
Small spills/leaks Evacuate area and ventilate. Wear protective equipment. If required, use an inert absrobent. Sweep up and place in an appropriate container for disposal. Wash contaminated surfaces.
Stability Water solutions foam strongly when shaken.

Fire.
Fire fighting Alcohol foam, carbon dioxide, dry chemical, water fog.
Fire potential Slightly flammable.

Health.
Poison_Class 3
Exposure effects CNS depression progressing to coma, seizures, shock, and respiratory muscle paralysis has been reported.
   Ingestion Vomiting, diarrhea and abdominal pain may occur. Ingestion of concentrated solutions may produce burns of the mouth, pharynx, and esophagus. Hemorrhagic gi tract necrosis and peritonitis have been reported.
   Inhalation Respiratory muscle paralysis, pulmonary edema, occupational asthma, and hypoxemia have been reported.
   Skin Dermal necrosis has resulted from exposure to cetrimonium bromide in concentrations ranging from 2 to 17.5 Percent. A number of these agents have caused irritant or allergic contact dermatitis.

First aid
 
   Ingestion Do not induce emesis - dilution: following ingestion and/or prior to gastric evacuation, immediately dilute with 4 to 8 ounces (120 to 240 ml) of milk or water (not to exceed 15 ml/kg in a child). The possible benefit of early removal of some ingested material by cautious gastric lavage must be weighed against potential complications of bleeding or perforation.
   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, wash exposed area with copious amounts of water. A physician should examine the area if irritation or pain persists.
   Eyes Eye exposure results in mild discomfort (0.1 Percent solution) to very serious corneal damage (1 to 10 percent solution) depending on the concentration. 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.
