(b)
the occupational exposure limits for protection against heat stress and cold stress are followed as well as the work-rest regimen for heat, the work-warming regimen for cold and other advice found in the ACGIH publication entitled “2016 Threshold Limit Values for Chemical Substances and Physical Agents and Biological Exposure Indices”.
