Why is Cooling Important
Heat stress is a serious problem.
Like other unsafe work conditions, heat stress lowers
productivity and increases accident and error rates. All of
which contribute to the cost of doing business.
Productivity lost to high temperatures is well documented.
As the table from NASA report CR-1205-1 indicates, when
temperatures in the work environment rise to 90 degrees,
output drops 29% and errors increase 300%!
Cool, comfortable work environments directly
contribute to productivity, quality and protability.
Keep your employees happy & stress free!
Safe working conditions keep workers' compensation rates down while minimizing disruptions and down time. As illustrated above,
errors increase which may compromise good safety practices leading to more accidents. Low morale can be direct result of heat stress in
the workplace. Low morale causes high employee turnover, absenteeism and work slow-down. Businesses cannot afford the costs of
temporary employees to make up for lost productivity caused by heat stress.
Today's managers & supervisors should be trained to watch for signs of heat stress. Personal protective equipment including fans,
appropriate rest periods, liquids and modified work practices can reduce the risk of heat stress. Employees must understand the need to
replace fluids and salt while watching for signs of dehydration, fainting, heat cramps, heat exhaustion and heat stroke.
