Which of the following is an example of a primary prevention strategy in workplace safety?

A primary prevention strategy aims to prevent hazards from occurring in the first place by addressing the root causes of potential risks. Eliminating a hazardous material from the workplace exemplifies this approach, as it removes the inherent danger associated with that material before any incidents can occur. By this action, the risk of exposure or accidents related to the hazardous material is entirely mitigated, promoting a safer work environment.

In contrast, the other options focus on different aspects of safety management. Providing personal protective equipment is a form of secondary prevention, as it aims to protect workers when hazards cannot be completely eliminated. Implementing a safety training program is also a secondary prevention measure, focusing on the education of workers to handle existing hazards safely rather than removing them. Conducting accident investigations is a reactive approach that deals with incidents after they occur, making it part of tertiary prevention by seeking to learn from past events to avoid future occurrences.
