How often must proof tests on personnel platforms be done?

• A. Every time the crane enters a new jobsite and after repairs or modifications to the personnel platform.
• B. Once a year.
• C. Only after an incident.
• D. Never.

Answer: (A)

Proof testing a personnel platform verifies that the platform and its attachments can safely carry the intended load and that safety features like pins, locks, and guardrails function correctly before use. Because each jobsite can present different rigging, anchor points, and setup, and because repairs or modifications can change the platform’s strength or how it’s attached to the crane, the test must be done whenever the crane enters a new jobsite or after any repairs or modifications to the platform. This proactive check helps catch issues that could cause failure under load before they lead to an incident. Doing proof tests only annually, only after an incident, or never would miss site-specific or post-modification problems and is not acceptable practice.
