In accordance with the updated Industrial Safety and Health Act (ISHA), which will go into effect on April 1, 2024, Japan enacted occupational exposure limits and risk assessment standards for 67 chemicals.
Companies must comply with a statement from the Ministry of Health, Labor, and Welfare.
Ensure that employees are exposed to chemicals at work that are below or equal to the MHLW-regulated exposure limits for 67 compounds, commonly known as ""concentration standard values"";
Abide by the requirements for measuring the workplace environment, such as measuring worker exposure over both short- and long-term periods of time (8 hours);
Utilize different materials, procedures, safety gear, and other risk-reduction measures based on the findings of the risk assessment to reduce worker exposure; and
Fulfil the criteria for sampling and data analysis for risk assessment.
The following substances have established standards for concentration:
- - 2 ppm of ethylidene norbornene, with a 4-ppm short-term limit;
- - 10 ppm long-term, 15 ppm short-term vinyl acetate, and
- - 10 ppm long-term, 50 ppm short-term ethylene glycol
