Under which condition must a medical exam be given according to OSHA regulations?

The correct answer is the requirement for a medical exam when an employee works in Class 1-3 asbestos jobs for 30 days within a year. This stipulation is designed to ensure that workers who may be exposed to asbestos are adequately monitored for health issues that can arise from such exposure, as the risks of asbestos-related diseases can increase with the duration of exposure.

The regulations reflect the understanding that even a limited amount of asbestos exposure can pose health risks, and the medical examinations serve to establish a baseline of health for workers. This proactive approach allows for early detection of potential health issues and promotes worker safety in environments where asbestos is present.

In contrast, other conditions outlined in the other choices do not align with the specific OSHA standards regarding medical exams for those handling asbestos. For instance, the option that suggests a medical exam is only necessary when an employee is suspected of exposure is too narrow and does not account for the systematic monitoring required by OSHA. Similarly, the notion that workers in low-risk environments for more than 60 days might necessitate a medical exam overlooks the direct correlation between asbestos exposure and the need for medical surveillance. Lastly, while employee requests for a medical review can lead to assessments, it is not the primary trigger for mandated medical exams under
