Occupational and Environmental Health: Recognizing and Preventing Disease and Injury - Multiple Choice Questions - Learn & Prevent

What can significant variation in exposure levels among workers indicate?

1. A need for better environmental monitoring equipment

2. A need for reevaluation of work practices and training

3. That some workers are not following safety protocols

4. That the ventilation system is malfunctioning

The correct answer is: A need for reevaluation of work practices and training

Significant variation in exposure levels among workers can indicate a need for reevaluation of work practices and training because it suggests that workers may not all be following the same safety procedures and may require more training on how to properly handle potentially hazardous materials. This can also be an indication that the current work practices may not be effective in preventing exposure and need to be reevaluated. This option is more applicable compared to option A, as there may not necessarily be an issue with the environmental monitoring equipment. Option C may be a contributing factor, but may not be the sole reason for the variation in exposure levels. Option D may also be a factor, but the focus should be on reevaluating work practices and providing proper training to ensure the safety of all workers.
