RICHLAND, Wash.- Record heat isn't stopping Hanford workers, but they do have a strict safety policy that determines when to work and when to stop.
A variety of factors make that decision for CH2M Hill workers.
Temperature, humidity, physical stress and how much protective clothing they have to wear are all factored into a strict equation that makes the decision.
They say they have to work, even if it's uncomfortable, but if it's too hot or too humid, they stop work to ensure no one gets hurt on the job.
"You compare the readings from this instrument to the reading on the chart and that determines if you go into a work rest regimen," said Kirk Higby, who helps run the program.
Even when they can work, they're often required to take periodic breaks multiple times throughout the day.
They also wear tags that describe the symptoms of heat stroke and direct them to stop their coworkers if they show any signs.
