Which action is included in Unit Commander's responsibilities for the thermal stress program?

• A. Managing work/rest schedules
• B. Performs initial surveillance
• C. WBGT measurement
• D. Environmental monitoring for heat and cold injury risk assessment

Answer: (A)

The action being tested is the unit commander’s authority to control exposure by arranging work/rest schedules. This is a direct, practical step the commander can take to prevent heat stress: they can set when and how long workers should rest, rotate tasks, and pace workloads based on hot conditions, ensuring people have access to water, shade, and cooling as needed. These scheduling decisions are within the unit level control and immediate duty to protect personnel. The other tasks are typically handled by specialized personnel: initial surveillance is conducted by medical or industrial hygiene staff to establish baseline risk, WBGT measurement requires proper equipment and trained measurement personnel, and environmental monitoring for heat and cold injury risk assessment is part of the broader safety or environmental health program managed by qualified specialists.
