What is the most preferred control at the top of the hierarchy of safety control?

The most preferred control at the top of the hierarchy of safety control is the elimination of the hazard. This approach is the most effective way to ensure safety because it involves completely removing the source of risk, thereby preventing any exposure or potential harm to individuals. By focusing on eliminating hazards, organizations can create a safer environment without the need for further interventions or controls.

When hazards are eliminated, there are no risks associated with them, which means there are no accidents or incidents tied to those hazards. This proactive measure not only enhances safety but also reduces the need for additional controls that manage risks, such as engineering controls and personal protective equipment (PPE). In situations where hazards cannot be eliminated, other controls can be considered, but the ideal and most effective strategy remains hazard elimination.
