What is considered the preferred method of hazard control when elimination is not possible?

Engineering controls are considered the preferred method of hazard control when elimination of the hazard is not possible because they aim to isolate employees from the hazard itself. These controls involve physical modifications to the workplace, such as the installation of ventilation systems, barriers, or machinery safeguards, that reduce or eliminate the risks associated with hazards.

The effectiveness of engineering controls lies in their proactive approach to workplace safety. They can significantly reduce the likelihood of accidents by changing the way work is performed or by ensuring that hazards are contained and do not reach the worker. This method not only protects employees but also minimizes reliance on human behavior or compliance, which can often lead to inconsistency in safety practices.

While administrative controls and personal protective equipment serve important roles in workplace safety, they do not address the hazard at its source as effectively as engineering controls. Administrative controls focus on altering the way people perform their jobs, which can be subject to variability based on human factors. Personal protective equipment provides a layer of defense against hazards but does not eliminate the hazard itself, and therefore might not be as effective in preventing injuries or accidents. Behavioral safety training, while valuable for promoting safe practices, relies on employee adherence and may not directly mitigate hazards in the operational environment.

Thus, engineering controls provide the most reliable
