What action is taken if a work station exceeds 100 °F?

Implementing a heat stress survey is the appropriate action when a work station exceeds 100 °F because it allows for a systematic assessment of the heat exposure and the risk of heat-related illnesses for personnel working in that environment. This survey enables supervisors to gather critical data about the working conditions, evaluate the potential impact on workers, and determine necessary adjustments or interventions.

A heat stress survey typically involves measuring temperature, humidity, and other factors that contribute to heat stress. The results guide management in making informed decisions to protect workers' health and safety, ensuring that any necessary measures, such as work-rest cycles or personal protective equipment, can be appropriately implemented.

The other choices may involve safety considerations, but they do not directly address the need to assess the situation methodically. Conducting a safety briefing may provide workers with information but would not evaluate the specific conditions of the work station. Stopping all operations could be an extreme measure and may not be necessary if the heat stress survey reveals that corrective actions can be taken. Providing additional cooling systems is a viable option, but it should be based on the findings of the heat stress survey to ensure the most effective and appropriate solutions are implemented.
