What are engineering controls in a workplace?

Engineering controls are measures designed to isolate or remove hazards from the workplace, making them a primary strategy in workplace safety. These controls typically involve physical modifications to the workplace environment or equipment which can help to minimize or eliminate risks that may cause injury or illness to employees. For example, installing machine guards, using ventilation systems to reduce exposure to airborne contaminants, or designing workstations that reduce ergonomic risks are all examples of engineering controls.

This approach is foundational in occupational health and safety because it addresses hazards at their source rather than relying solely on behavioral changes or personal protective equipment (PPE). By implementing engineering controls, employers can create a safer environment that reduces reliance on workers to engage in safe practices and mitigates the overall risk of workplace accidents or health issues. The effectiveness of these controls often surpasses that of training or personal protective measures since these interventions fundamentally change the environment or process to minimize exposure to hazards.
