Which of the following methods is unacceptable for protecting employees from radiant heat sources?

1. Install reflective barriers

2. Increase ventilation

3. Provide heat-resistant clothing

4. Use cooling devices

The correct answer is: Increase ventilation

Increasing ventilation is considered an unacceptable method for protecting employees from radiant heat sources because while it may help to reduce overall air temperature or disperse heat, it does not directly protect workers from the specific risks associated with radiant heat exposure. Radiant heat can cause burns or heat stress regardless of how much airflow is present. On the other hand, options such as installing reflective barriers, providing heat-resistant clothing, and using cooling devices are effective strategies. Reflective barriers can redirect or absorb radiant heat before it reaches the employee. Heat-resistant clothing can protect the skin from thermal radiation. Cooling devices, such as air conditioning or personal cooling systems, help maintain body temperature and reduce heat stress. These methods provide more direct and effective protection against the dangers posed by radiant heat sources.
