How many hours in a working day are defined for long term exposure limits according to Schedule 6 of CMSHR?

In Schedule 6 of the Coal Mining Safety and Health Regulations (CMSHR), long-term exposure limits are defined based on an 8-hour working day. This standard is set to provide a consistent measure for assessing occupational exposure to hazardous substances in mining operations. The definition of an 8-hour day aligns with typical shift lengths in many industries, promoting worker safety by ensuring that exposure limits are based on a reasonable and widely accepted duration of time for work.

This framework is essential as it helps in ensuring that workers do not exceed the permissible exposure limits, thereby minimizing the risk of negative health effects associated with prolonged exposure to harmful substances. Thus, using an 8-hour workday as a benchmark makes it easier to evaluate and compare the exposure levels against the established safety standards.
