Hazards and Protection.
Protect from light. Cresol
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.
Eye protection should be provided against droplets or spray. Organic vapor canister unit (usbm type b) approved by us bureau of mines; rubber gloves, face shield, coveralls and/or rubber apron, rubber shoes, or boots. To prevent absorption through skin. wear rubber hand protection and aprons.
Wear positive pressure self-contained breathing apparatus (SCBA).
ELIMINATE all ignition sources. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS.
Crystals or liquid darken with exposure to air and light.
Dangerous. It can react vigorously with oxidizing materials.
Small Fires: Dry chemical, carbon dioxide or water spray. Large Fires: Dry chemical, carbon dioxide, alcohol-resistant foam or water spray.
Dangerous, when exposed to heat or flame.
When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards.
Flammable toxic vapors are given off in a fire.
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. Emesis: 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.
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.
Remove phenol with undiluted polyethylene glycol 300 to 400 or isopropyl alcohol prior to washing, if readily available. Wash exposed areas twice with large quantities of water. A physician may need to examine the exposed area if irritation or pain persist after the area is washed.
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.
