Bioenvironmental Engineering is responsible for recommending controls to mitigate health risks associated with identified health threats/hazards. They have the expertise and knowledge to assess and evaluate the potential risks and hazards in the environment and provide recommendations on how to control and minimize those risks. This includes measures such as implementing safety protocols, conducting regular inspections, and providing guidance on the proper use of protective equipment. The other options, such as the Installation Safety Office, Base Civil Engineer, and Supervisors, may have roles in implementing and enforcing these controls, but it is the Bioenvironmental Engineering department that recommends them.

The correct answer is 475. The Air Force uses AF Form 475 to report a hazard. This form is used to document and report any potential hazards or unsafe conditions that may pose a risk to personnel, equipment, or operations. By using this form, the Air Force can identify and address these hazards in order to ensure the safety and well-being of its personnel and assets.

The use of personal protective equipment (PPE) is considered the least preferred method when controlling hazards because it only protects the individual wearing the PPE and does not address the hazard at its source. It should not be relied upon alone to protect against hazards as it does not eliminate or reduce the hazard, but rather provides a barrier between the hazard and the individual. It is more effective to eliminate or reduce the hazard through methods such as isolating operations, providing administrative controls, or substituting a less hazardous material or process.

To determine if an intrusion detection system is required or if another supplemental control is sufficient, a risk assessment needs to be conducted. This involves evaluating the potential risks and threats to the system and assessing the likelihood and impact of those risks.
