Which engineering controls help prevent heat stroke?

The option that focuses on scheduling work in cooler hours and using portable cooling fans effectively addresses the need to mitigate heat-related illnesses, including heat stroke. Engineering controls are designed to modify the work environment to enhance safety and health.

Scheduling work during the cooler parts of the day can significantly reduce exposure to extreme heat, decreasing the risk of heat stress on workers. By avoiding high temperatures that typically occur in the midday sun, employers can help maintain safe working conditions.

Additionally, the use of portable cooling fans can facilitate better airflow and provide localized cooling in areas where temperatures may become elevated. This combination of adjusting work hours and implementing cooling aids aligns with best practices for preventing heat-related illnesses, fostering a safer work environment that proactively addresses thermal stressors.
