Which CIM describes heat stress monitoring equipment such as the WBGT meter?

• A. CIM 6260.17
• B. CIM 6000.1
• C. CIM 6200.1
• D. CIM 6300.1

Answer: (A)

Heat-stress assessment relies on using standardized equipment to measure environmental conditions that drive heat strain, with the WBGT meter being a common tool for this purpose. CIM 6260.17 is the reference that specifies heat-stress monitoring equipment, including WBGT meters, detailing what equipment is approved, how it should be calibrated and maintained, and how readings should be used to protect personnel (for example, informing work/rest cycles, hydration, and protective measures). This guidance ensures measurements are accurate, consistent, and applicable across Coast Guard settings, which is why it’s the best answer for describing the equipment used to monitor heat stress. The other CIMs cover topics outside heat-stress monitoring gear, so they don’t provide the specific guidance on selecting, calibrating, and applying WBGT-based measurements.
