According to the 8th edition of the Guide, what must institutions have in place regarding occupational health?

The correct response indicates that institutions are required to have specific measures in place concerning occupational health. According to the 8th edition of the Guide for the Care and Use of Laboratory Animals, it is emphasized that institutions must establish an occupational health program that adequately protects personnel who are at risk of exposure to hazards when working with research animals.

This requirement highlights the importance of ensuring the safety and well-being of staff members involved in animal research, facilitating appropriate protective measures, health monitoring, and education on potential risks. The use of "must" suggests a mandatory action that all institutions need to adhere to, thereby underscoring the obligation to protect their employees from health issues potentially arising from working in animal research environments.

The other options do not capture the mandatory nature of these requirements as presented in the Guide, hence leading to the conclusion that having measures in place concerning occupational health is indeed a "must."
