Which of the following best describes an administrative control?

Administrative controls involve implementing policies, procedures, and practices within the workplace to manage risk and improve safety. The correct choice, which describes an administrative control, is job rotation to reduce exposure.

Job rotation is a strategy where employees are moved between different tasks or workstations to minimize their exposure to hazards. This approach can help prevent fatigue and reduce the risk associated with repetitive tasks or prolonged exposure to certain risks. It emphasizes the management of working conditions and employee practices to enhance safety and wellbeing, rather than relying on physical modifications or personal protective equipment.

In contrast, the other options represent different types of controls. Requiring employees to wear safety gear pertains to personal protective equipment (PPE), which is considered a form of engineering control as it aims to protect individuals from hazards rather than changing the work process itself. Installing machine guards is another engineering control, focusing on modifying equipment to enhance safety. Substituting a less hazardous material is a form of substitution control, aiming to eliminate or reduce hazards by changing the materials used in a process. Each of these approaches serves to improve safety, but they do not fit the definition of administrative controls.
