According to HG/T20660-2000, is trichloromethane (chloroform) a highly hazardous or moderately hazardous substance?

According to the HG/T20660-2000 standard, trichloromethane (chloroform) is classified as a highly hazardous medium. This is because trichloromethane is highly toxic and volatile, and can pose a serious threat to human health through inhalation, ingestion, or skin contact. .

Trichloromethane (chloroform) is generally considered a medium-hazard substance, rather than a high-hazard substance. Toxicity classification: In the toxicity classification of chemical agents, highly hazardous agents typically refer to those with extremely high toxicity that can rapidly cause severe injuries or even death. Although trichloromethane is toxic, its toxicity is relatively low; a certain level of exposure is required to cause severe poisoning. Exposure risk: The exposure risk to trichloromethane depends on the working environment, the methods of operation, and the effectiveness of personal protective measures. By strictly following operating procedures and wearing protective equipment, the risk of exposure can be significantly reduced. Treatment measures: For patients poisoned by trichloromethane, taking actions such as removing them from the affected area promptly, maintaining an open airway, and seeking medical attention can help control the condition and reduce the occurrence of complications.
