A rule made mandatory by a federal, state, or local government.

• A. Lift planning
• B. NIOSH FACE program
• C. Standards
• D. Regulation

Answer: (D)

Regulation refers to a rule created by federal, state, or local government that is legally binding and enforceable, with penalties for noncompliance. In safety for line work, regulations come from agencies like OSHA and specify mandatory requirements that must be followed. Standards, while important for safety, are usually voluntary guidelines developed by consensus bodies (such as ANSI or NFPA) and only become mandatory if a regulation or law adopts or references them. The NIOSH FACE program is a research and data-collection effort, not a binding rule, and lift planning is a safety process, not a government-m issued rule. So the rule described as mandatory by government is a regulation.
