Which of the following describes engineering controls in the context of bloodborne pathogens?

Engineering controls in the context of bloodborne pathogens refer to methods that isolate or remove hazards from the workplace. This includes the use of devices and measures actively designed to prevent exposure to harmful pathogens, like safer needle devices, work practice controls, and biohazard containers. By focusing on containment or elimination of the risk, engineering controls address the source of exposure before it even reaches the worker, ensuring a safer environment.

In this scenario, options like training workers on safety procedures and providing personal protective equipment are important components of an overall safety program but do not fall under the umbrella of engineering controls. Training develops worker awareness and knowledge, while personal protective equipment is a layer of protection rather than a source of eliminating the hazard itself. Similarly, implementing fall protection measures pertains more to physical safety in relation to height and fall risks rather than exposure to bloodborne pathogens. Thus, the emphasis here is on the proactive removal or isolation of the hazards, which is precisely what engineering controls achieve.
