CHST Practice Test – Complete Exam Preparation

The requirement for supplemental information in the medical evaluation for respiratory protection is based on ensuring that employees are fit to use the equipment safely. OSHA mandates specific information that relates directly to an employee's ability to wear a respirator effectively.

The medical history of the employee is crucial as it provides insights into any pre-existing conditions that may affect their capacity to use a respirator. Results of pulmonary function tests are vital to assess lung capacity and respiratory health, ensuring that the employee can safely wear respiratory protection without risk to their health. Additionally, knowing the type and weight of respirators used helps identify any specific considerations regarding fit and comfort that might affect the employee’s ability to wear the equipment properly.

In contrast, employee drug screen results do not directly relate to the individual's capacity to safely use a respirator or their respiratory health. While drug use may have implications for overall workplace safety, it is not a required element of the medical evaluation specifically concerning respiratory protection, making it supplemental information that is not necessary for the assessment according to OSHA standards. This focus on health and fitness specifically related to respirator use clarifies why the other options are essential components of the evaluation.
