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 approved dust respirator for toxic dusts; goggles; protective clothing to prevent contact with skin. wear boots, protective gloves, and goggles.
Use NIOSH/MSHA approved respirator appropriate for exposure of concern.
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.
Emits hydrogen clhoride and disodium oxide fumes when heated to decomposition.
Fire Extinguishing Agents: Water fog, CO 2 or dry chemical.
Non-combustible trichlorophenol nonflammable trichlorophenol
Emits noxious fumes.
Abnormally low blood pressure, reduced body temperature, rapid breathing, and rapid heart rate may develop with severe toxicity. Initial CNS excitation, including seizures, is commonly followed by CNS depression ranging from lethargy to coma and death. Fetotoxicity and skeletal abnormalities have been reported in animal experiments.
Phenol is extremely corrosive and may cause oral and esophageal burns and abdominal pain following ingestion.
Tachypnea is commonly reported; pulmonary edema and bronchospasm may also occur. Stridor has been reported from exposure to high concentrations of phenol. Respiratory arrest occurred 30 minutes post ingestion of 26.7 Grams of phenol in one case.
Phenol is corrosive to the skin, but because of anesthetic qualities, it will numb rather than causing a burning pain on contact. Skin becomes red and swollen, then white and opaque. Deep burns result that may become gangrenous.
Dilution - may enhance absorption of phenol, and should be avoided. Ipecac induced vomiting is not recommended because of the potential for cns depression and seizures. Activated charcoal - may limit systemic toxicity if administered soon after ingestion, but may interfere with endoscopic evaluation of gastrointestinal burns.
Remove to fresh air. If needed give artificial respiration.
Wash with soap and water.
Flush with running water.
