A heat stress survey should be conducted when the work station dry-bulb reading exceeds what temperature?

A heat stress survey is important for ensuring the safety and health of personnel working in high-temperature environments. The threshold for conducting such a survey is based on established guidelines that indicate potential risks associated with heat exposure. When the dry-bulb temperature exceeds 100 degrees Fahrenheit, it signals a significant increase in heat stress risk, necessitating a thorough evaluation of work conditions.

This temperature serves as a critical marker because it aligns with research and industry standards that highlight the onset of heat-related illnesses and the physiological strain on workers. At temperatures above this threshold, additional preventive measures, such as hydration strategies or work-rest cycles, become essential to protect personnel from heat stress. Thus, conducting a survey at this temperature ensures that appropriate actions can be implemented to mitigate health risks effectively.
