Japanese standards on chemical classification, labelling and safety data sheets (SDSs), JIS Z 7252 and JIS Z 7253, have been aligned with the Globally Harmonized System (GHS) Rev.6.Until May, 24, 2022, chemical suppliers were given the time to arrange and update relevant SDSs and labels to adapt to new requirements. GHS labels and SDSs are mandatory for the chemicals regulated by the three main clauses for chemicals in Japan, that is, the Industrial Safety and Health Law (ISHL), the Pollutant Release and Transfer Register (PRTR) Law and the Poisonous and Deleterious Substances Control Law (PDSCL).
Whereas for other chemicals falling outside these regulatory categories, implementation of GHS classification and hazard communication elements is encouraged. Despite their different applicable scopes, these laws overall convey the same standards on the criteria for classification, labeling and SDS preparation for:
The notable revision after these standards were published in May 2019, was the incorporation of an additional hazard class for desensitized explosives with new H statements, H206 to H208, into the standards. A sub-hazard category (i.e., Pyrophoric gas) was also introduced for flammable gases.
Noteworthily, the 3-year grace period expired on May 24, 2022. Therefore, individuals have to follow up with the new requirements to ensure compliance within the industry.
