Design factor

Hazards

• The ratio relating a component or system’s failure strength to its permitted working load under defined conditions.

Controls

• The required factor depends on material, use, dynamics, people, standard, and jurisdiction; it does not authorize exceeding the marked WLL or ignoring inspection.

Personal protective equipment

• Select task-specific PPE only after hazards and higher-order controls have been evaluated.

Regional considerations

• Applicable law, permits, collective agreements, venue rules, and qualified-person decisions take precedence.
