According to the guidelines, what is the recommended workload for new workers on their first day in a hot environment?

1. 50%

2. 20%

3. 80%

4. 100%

The correct answer is: 20%

The recommended workload for new workers on their first day in a hot environment is set at 20%. This guideline is based on the principle of gradually acclimatizing workers to hot conditions, particularly if they are not accustomed to performing physical tasks in high temperatures. Starting with a workload of 20% allows new workers to adapt to the heat stress without overwhelming their bodies, which can lead to heat-related illnesses such as heat exhaustion or heat stroke. This gradual approach is important as it minimizes the risk of fatigue and other heat-related health issues, which can be more severe for individuals who are unaccustomed to the conditions. As workers become more acclimatized over time, their workload can be increased accordingly. This step-by-step adaptation helps ensure their safety and effectiveness in challenging environments. The other percentages—50%, 80%, and 100%—represent workloads that would likely expose new employees to heat stress too quickly, which is contrary to safe practices in occupational health and safety regarding hot environments.
