Who trains employees to protect themselves against hazards from thermal stress?

• A. Unit Commander
• B. AF Form 55
• C. Worker
• D. Workplace Supervisor

Answer: (D)

Training responsibility for protecting workers from thermal stress rests with the supervisor who oversees the work area. They’re the one who directly interacts with the crew, knows the specific tasks and exposure conditions, and can tailor safety guidance to prevent heat or cold illness. The supervisor teaches how to recognize symptoms, use protective measures, stay hydrated, acclimate, pace work, schedule breaks, and apply PPE or engineering controls, and ensures the training happens and is documented.

A unit commander sets policy at a higher level but does not typically deliver day-to-day, job-specific training. AF Form 55 is a record of training, not the trainer. A worker can learn from others, but the responsibility to train the crew sits with the workplace supervisor.
