Which of the following is considered an engineering control?

The choice of segregation of the hazard in time and space as an engineering control is well-grounded in the principles of Occupational Health and Safety. Engineering controls involve modifying the workplace or changing the physical environment to reduce or eliminate exposure to hazards. By segregating the hazard, either by limiting the time that workers are exposed to it or by creating a physical barrier to keep workers separate from the hazard, the risk of injury or illness is significantly reduced. This method focuses on minimizing exposure at its source rather than relying solely on worker behavior or personal protective equipment.

In contrast, recognizing the source of the hazard is related to hazard identification but does not directly address how to mitigate the risk it poses. Using personal protective equipment is often considered an administrative control since it relies on the individual worker to use the equipment appropriately. Contacting the Ministry of Labour after an incident pertains to regulatory compliance and incident reporting rather than a proactive measure to control hazards through engineering solutions.
