Requires that all lifts be categorized as ordinary, critical, preengineered production, or personnel before a lift is planned and executed.

Requires that all lifts be categorized as ordinary, critical, preengineered production, or personnel before a lift is planned and executed.

• A. ASME standard
• B. Workplace accidents
• C. Standards
• D. Regulation

Answer: (A)

Classifying every lift by risk level before planning is a fundamental rigging practice. This categorization guides what gear, procedures, crew qualifications, and supervision are needed, tying the planning process to the lift’s complexity and hazard. The authoritative source that defines and requires these lift categories is the ASME standards for rigging. They specify the categories—ordinary, critical, preengineered production, and personnel—and mandate that lifts be assigned to one of them before planning progresses. This makes ASME standards the best answer because they provide the exact framework and requirements used in the field. Stretched against the other options, standards is too broad and lacks the precise, actionable direction; regulation implies legal requirements that vary by jurisdiction and isn’t the primary source of this specific categorization; workplace accidents describe outcomes rather than the planning process itself.
