Last time, Dr. François Haman gave us the cold playbook. Now he is back with the heat playbook. A professor of thermophysiology at the University of Ottawa, Dr. Haman joins Dr. Kevin Rindal to break down heat stress at work: why humidity matters more than temperature, the difference between heat exhaustion and heat stroke, and the five modifiable factors that keep a crew safe while working in extreme heat. Practical, science-backed heat safety for utility and construction workers.
