Which set of factors influences the selection of hazard controls?

• A. PPE, training, and maintenance
• B. Weather conditions
• C. Legislation, scope of work, and client requirements
• D. Noise levels

Answer: (C)

Selecting hazard controls is guided by the project’s legal and contractual context and the specifics of the work being undertaken. Legislation and standards establish the minimum safety obligations you must meet, while the scope of work shows which activities are happening, in what environment, and what hazards are present. Client requirements may add safety expectations or mandated measures that must be included in the plan. Together, these factors determine what controls are appropriate, feasible, and compliant for the task at hand. After this foundation is set, a risk assessment helps decide the exact controls within the hierarchy of elimination, substitution, engineering and administrative controls, and PPE.

Weather conditions and similar environmental factors can affect how a given control is implemented, and the level of a hazard like noise informs the need for specific protections, but they do not by themselves establish the overall set of controls. PPE, training, and maintenance are components of the controls you implement, not the factors that determine which controls to choose.
