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
