Final answer:
The engineering control from the options provided is segregating the hazard in time and space. Engineering controls involve modifying systems to enhance safety and prevent hazards, which are more effective than administrative controls or personal protective equipment.
Step-by-step explanation:
The option that is an engineering control is b. segregating the hazard in time and space. Engineering controls are strategies designed to protect workers by modifying or redesigning equipment, processes, or the work environment to minimize the exposure and contact to hazards. They are preferred over other forms of risk management because they are built into the design of systems and can offer inherent safety benefits that prevent a hazard from occurring. Examples include installing physical barriers, such as guardrails or isolation of a hazard, or using technology to improve safety, such as mechanical lifts that reduce the need for manual lifting. Other options like using personal protective equipment or contacting the Ministry of Labour are considered administrative controls or post-event actions and are not engineering controls that mitigate the hazard at the source.
