Is phenol moderately hazardous or highly hazardous?
You need to calculate this by yourself. I’ve done the calculation for THI68, and it falls into the category of extremely hazardous. Of course, the specific values can vary; different people may arrive at different results. Take a look at GBZ 230-2010, and also check out the website http://msds.anquan.com.cn/, and you’ll be able to determine the values roughly.
It used to be classified as a toxic hazard, but now it seems to be considered a high-risk hazard!
It is now classified as a highly hazardous substance; one can refer to the standard \"Classification Criteria for the Toxicity and Explosive Hazard of Chemical Substances in Pressure Vessels\" (HG-T20660-2017). This standard provides formulas based on the grading system for the hazards associated with occupational exposure to toxic substances (GB/Z230-2010), and using these formulas, phenol is determined to be a highly hazardous substance.
