In the hierarchy of hazard controls in OH&S, which category comes after engineering controls?

• A. PPE
• B. Administrative
• C. Engineering
• D. Elimination

Answer: (B)

In safety controls, measures are arranged from strongest to weakest. After engineering controls—physical changes that separate people from the hazard—the next level is administrative controls. These modify how work is done to reduce exposure, not by removing the hazard itself but by changing practices, timing, and supervision. In welding, this includes thorough training, clear and safe operating procedures, supervision, rotating workers to limit time exposed, and scheduling to minimize continuous exposure. These reduce risk by shaping behavior and workflow, while PPE remains the final layer of protection when exposure still can't be fully avoided.
