How to prevent chloroform poisoning

Trichloromethane mainly acts on the central nervous system and has an anesthetic effect, which is harmful to heart, liver and kidney. Acute poisoning: Acute poisoning caused by inhalation or absorption through the skin. Initially there are headaches, dizziness, nausea, vomiting, excitement, hot and humid skin and mucous membrane irritation. Later, there will be mental disorders, superficial breathing, reflexes, coma, etc., and severe respiratory paralysis and ventricular fibrillation. It can also be accompanied by liver and kidney damage. When intoxicated, the stomach has a burning sensation, accompanied by nausea, vomiting, abdominal pain, and diarrhea. Anesthesia symptoms appear later. Liquid can cause dermatitis, eczema, and even skin burns. Chronic effects: mainly cause liver damage, and have symptoms such as indigestion, fatigue, headache, insomnia, and a few have kidney damage and chloroform.

Life care:
Treatment 1. Remove the patient's source of exposure and treat it according to its symptoms.
2. Skin contact: Remove contaminated clothing and rinse with water.
3. Eye contact: Flush eyes with plenty of water for at least 15 minutes.
4. Oral: Avoid vomiting. If you have just taken in, consider gastric lavage and active carbon treatment, but pay attention to the protection of the respiratory tract and avoid aspiration pneumonia.
5. Inhalation injury: Move to fresh air, monitor breathing, and give 100% oxygen if you have respiratory discomfort.

Precautions: Switch to other less toxic solvents such as gasoline and kerosene as cleaning agents. Attention should be paid to the sealing of the equipment during production, to enhance ventilation and personal protection, and to avoid skin contact. People with liver disease should not be exposed. Chloroform is exposed to ultraviolet light and high heat, which can form phosgene. It is highly toxic and must be protected. 1%~2% ethanol can be added to the chloroform storage to make the phosgene and ethanol react to form ethyl carbonate to eliminate its toxicity.
