Which equipment must a painter prioritize over ladders to ensure collective fall protection?

• A. Mobile stairs and Mobile Elevating Work Platforms (MEWPs) equipped with guardrails.
• B. Personal fall arrest harnesses.
• C. Scaffolding without guardrails.
• D. Step stools.

Answer: (B)

When working at height, the priority is to have protection that covers the worker in case a fall occurs. Personal fall arrest harnesses provide this direct safety net by attaching to a secure anchor and stopping a fall before injury happens. They’re essential when you’re using ladders or moving around edges where guardrails or other collective protections aren’t in place or fully feasible. The harness doesn’t replace guardrails or stable work platforms, but it adds a reliable layer of safety that activates if a fall starts, which is why it’s treated as the best choice in this context.

By contrast, step stools offer little to no fall protection, scaffolding without guardrails is unsafe, and while mobile stairs or MEWPs with guardrails are valuable collective protections, they aren’t guaranteed in every situation. The harness complements these protections and is the most consistently protective option when ladders are involved.
