The choice of remediation as not usually considered an engineering control is grounded in the definition and classification of controls in Occupational Safety and Health. Engineering controls focus primarily on eliminating hazards or reducing exposure to harmful conditions through physical changes to the workplace. These can include systems designed to ventilate hazardous materials, guardrails that prevent falls, and other structural modifications that mitigate risks to workers.

Remediation, on the other hand, typically refers to the process of correcting or mitigating a hazardous situation after exposure has occurred. This can involve cleaning up spills, removing contaminated materials, or reclaiming a site. While it is an essential aspect of safety management and environmental health, it does not belong to the category of engineering controls, which are intended to proactively reduce risks before they impact workers.

Personal protective equipment is distinct from engineering controls as well, since it serves as a barrier between the worker and the hazard rather than modifying the hazard itself. Ventilation systems and guardrails are examples of engineering controls because they physically alter the environment to reduce risk.
