GHS Category - Hazardous to the Ozone Layer
Posted Date:2022/7/13
GHS Definition:
Ozone Depletion Potential (ODP) is a combined total that is distinct from a single halocarbon source, reflecting the potential contribution of halocarbons to the stratosphere compared to trichlorofluoromethane (CFC-11) of the same quality. Degree of ozone depletion. The formal definition of ODP is the ratio of the combined perturbation to the entire ozone layer of the differential emission of a certain compound relative to the equivalent mass of trichlorofluoromethane. "
The Montreal Protocol, means the Montreal Protocol on Substances that Deplete the Ozone Layer as amended and/or amended by the Parties to the Protocol
