Which of the following describes engineering controls?

Engineering controls refer to physical modifications to the workplace that are designed to isolate or remove hazards, thus reducing the likelihood of worker exposure to potential dangers. These controls can include things like the installation of ventilation systems, safety barriers, biocontainment materials, or devices that limit the spread of infectious agents, such as automatic door openers or hands-free sinks.

In the context of infection control, engineering controls might also encompass equipment that helps to reduce the risk of infection, such as negative pressure rooms in healthcare settings to prevent airborne pathogens from spreading.

By fundamentally altering the environment rather than relying solely on human behavior (like training or hygiene practices), engineering controls offer a more reliable and sustainable method of ensuring safety and reducing the risk of infections and other hazards in the workplace.
