What is an example of an engineering control?

An example of an engineering control is installing machine guards. Engineering controls are designed to minimize or eliminate exposure to hazards through the use of physical modifications to the workplace or to equipment. Machine guards serve as a physical barrier that protects workers from moving parts, which can reduce the risk of injuries such as cuts, lacerations, or entanglement.

These controls are preferred in safety management because they remove or isolate the hazard from the worker, rather than relying solely on personal protective equipment, administrative controls, or behavioral changes. By effectively incorporating engineering controls like machine guards, workplaces can create a safer environment, reducing the likelihood of accidents or injuries.

In contrast, the other options provided are types of controls but do not fall under the engineering category. Wearing gloves is considered personal protective equipment, conducting safety training pertains to administrative or training controls, and posting warning signs is a form of administrative control as well.
