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.

Josh Vitale came up as an electric lineman. Now he is the co-founder and CEO of Project BUILT and the 2025 chair of Construction Suicide Prevention Week.

He sits down with Dr. Kevin Rindal to talk about what he calls human extraction, the day he helped a crew member who was minutes from the worst, and why "How are you really doing?" is the most important question on any job site.

Honest and hopeful. On mental health, allies, purpose, and bringing family into the work of staying well. If you or someone you know is struggling, call or text 988, the Suicide and Crisis Lifeline.

Micah Thompson keeps people on the truck and out of the hospital. As Director of Loss Control and Training for the Electric Cooperatives of South Carolina, he is responsible for safety across eighteen co-ops that keep the lights on for nearly two million people. Four years ago he was climbing poles. Now he builds a safety culture that survives a storm season.

He sits down with Dr. Kevin Rindal for the inner game of safety: why the hardest part of the job is the human in front of you, not the rule book. Loss control, lineman mental health, and what it takes to do this work for twenty more years.

Your job can build you up instead of break you down. New episodes every Tuesday.
