How many hours per day should a worker's time in the high-temperature workplace not exceed?

The correct answer is that a worker's time in a high-temperature workplace should not exceed 6 hours per day. This guideline is based on health and safety recommendations to prevent heat-related illnesses, which can occur when workers are exposed to extreme temperatures for extended periods.

Prolonged exposure to high temperatures can lead to conditions such as heat exhaustion, heat stroke, and dehydration. By limiting the hours spent in such environments to 6 hours, it allows for adequate time for recovery, hydration, and preventive measures such as taking breaks in cooler environments.

Additionally, many occupational health guidelines suggest implementing such measures to ensure the safety and well-being of workers in high-temperature settings, making this duration a commonly accepted standard in various industries. Limiting exposure helps to reduce the risk of potential health impacts, supporting workers' overall productivity and safety.
