Phenol is a colorless needle-like crystal with a special odor. It is toxic and is an important raw material for the production of certain resins, fungicides, preservatives and drugs such as aspirin. It can also be used to disinfect surgical instruments and excreta, skin sterilization, itching and otitis media. The melting point of 43 ° C, slightly soluble in water at room temperature, soluble in organic solvents; when the temperature is higher than 65 ° C, it can be miscible with water in any ratio. Phenol is corrosive and denatures local proteins after contact. The solution is applied to the skin and washed with alcohol. A small portion of the phenol is exposed to the air and is oxidized by oxygen to strontium and is pink. In the case of trivalent iron ions becoming purple, this method is usually used to test phenol.
1 Skin contact: Immediately remove contaminated clothing, wash with glycerin, polyethylene glycol or a mixture of polyethylene glycol and alcohol (7:3), then rinse thoroughly with water. Or rinse with plenty of running water for at least 15 minutes. Seek medical attention.
2 Eye contact: Immediately lift eyelids and rinse thoroughly with plenty of running water or saline for at least 15 minutes. Seek medical attention.
Inhalation: Remove quickly from the scene to fresh air. Keep the airway open. If breathing is difficult, give oxygen. If breathing stops, perform artificial respiration immediately. Seek medical attention.
3 Ingestion: Immediately give 15~30mL of vegetable oil. Inducing vomiting. Seek medical attention.
Leakage emergency treatment
1 Emergency treatment: Isolation of contaminated areas and restrictions on access. Cut off the fire source. It is recommended that emergency personnel wear a dust mask (full face mask) and wear a protective suit.
2 Small amount of leakage: covered with dry lime and soda ash.
3 Large amount of leakage: collected or transported to a waste disposal site for disposal.
