What are the three types of controls used to manage risks?

The correct answer to the question about the three types of controls used to manage risks encompasses engineering controls, administrative controls, and personal protective equipment.

Engineering controls focus on designing the workplace and equipment to eliminate or reduce hazards. Examples include machinery safeguards or ventilation systems that minimize exposure to harmful substances. These controls are viewed as one of the most effective ways to manage risks because they often remove the hazard altogether or isolate workers from the risk.

Administrative controls involve modifying work practices and policies to reduce exposure to hazards. This can include training programs, job rotation to limit exposure time, and implementing safety protocols. Administrative controls are critical for ensuring that employees understand and adhere to safety measures that can mitigate risks.

Personal protective equipment (PPE) is essential when risks cannot be fully eliminated or modified through engineering and administrative controls. Examples include gloves, helmets, and goggles, which provide a barrier between the worker and the hazard. While PPE is important, it is typically considered the last line of defense after other controls have been applied.

Other options listed in the choices do not accurately reflect the established categories of risk management controls, as they mix different types of controls or introduce unrelated concepts. Understanding these three specific control types—engineering, administrative, and personal protective equipment—provides a
