What reflects the range of engineering controls used for protection against biohazards?

Engineering controls play a critical role in reducing employee exposure to biohazards within laboratory settings and other environments where biological agents are handled. The correct option emphasizes that the range of engineering controls includes both sophisticated and simple devices, demonstrating the versatility and adaptability of safety measures.

Sophisticated devices may refer to advanced containment systems such as Class II biosafety cabinets or air filtration systems that help prevent the escape of airborne pathogens. On the other hand, simple devices might include basic safety features like fume hoods, sharps disposal containers, or personal protective equipment (PPE) that together contribute to a safer working environment. The effectiveness of engineering controls does not solely depend on their complexity; rather, it is the proper implementation and use of these devices that determine their success in mitigating risk.

By acknowledging that engineering controls encompass a variety of devices, this option reinforces the idea that safety in handling biohazards can be enhanced through a mix of both advanced and practical solutions tailored to specific situations and types of work. This comprehensive approach helps ensure that all potential risks are addressed effectively, regardless of the complexity of the controls used.
