‌Absenteeism: Worker Compensation Claims
‌Examples from OSHA fatalities for exertional heat stroke

New York

At 3:30 p.m. on August 2, 2018, an employee was working at a recycling plant and was shredding plastic. Employee was working at recycling plant and presented at the emergency room personnel with signs of heat stroke.

‌Presenteeism: Reduced Physical Work

Examples from:

  1. Morabito M, Messeri A, Crisci A, et al. Heat-related productivity loss: benefits derived by working in the shade or work-time shifting. Int J Product Perform Manag 2020;70:507–25. doi:10.1108/IJPPM-10-2019-0500

  2. Foster J, Smallcombe J, Hodder S, et al. An advanced empirical model for quantifying the impact of heat and climate change on human physical work capacity. Int J Biometeorol 2021;:1–15. doi:10.1007/s00484-021-02105-0

    Economic Cost = Worker’s Salary x Productivity Loss (%) (1)

    Productivity Loss is a loss in physical capacity to do work, which affects work output

Physical capacity losses based on air temperature and Relative Humidity (2).


‌Worker Daily Salary: $400 per day
‌Ambient Temperature: 35° C
‌Relatvie Humidity: 45%

‌Economic Cost for one employer undergoing heat stress

‌Economic Cost = $400 x 0.71 = $284

The organization will have lost $284 dollars per worker per day based on the environmental conditions and worker daily salary.

‌10 workers = $2,840 a day!
‌100 workers = $28,400 a day!

‌Cost of Heat Safety Plan

‌Example: Cooling Vests

‌One cooling vest = approximately $50 per worker
‌10 workers = $500
‌100 workers = $5,000

For 100 workers: will you invest $5,000 for cooling equipment to save $28,400 a day
