Is ozone not a hazardous chemical?
Thread Content
Ozone has a stronger oxidizing power than oxygen; oxygen is classified as a Category B hazardous material, so ozone should also be classified as Category B. According to the \"Catalogue of Hazardous Chemicals\" (2015 edition), oxygen is considered a hazardous chemical, but ozone is not included in this list, which is strange.
This is a problem in the process of compiling the list. Just like the List of Highly Toxic Chemicals, some substances that do not qualify as highly toxic chemicals based on LD50 values are still required to be managed as such. For some chemicals with stronger toxicity, it is normal that they are not included in the list, as such substances do not exist domestically or are not used there at the time the list is compiled
Ozone is rarely stored; instead, ozone generators are purchased to produce it on demand, as it is needed.
Ozone is a hazardous chemical. For those not listed in the hazardous chemicals catalog, it is possible to determine whether they are hazardous chemicals through testing. There is a “List of 100 Chemicals Exempt from Testing,” in which ozone has already been classified as a hazardous chemical.
