Verify signal person qualification documentation required by OSHA 1926.1428 before hand-signaling crane picks on a steel erection site

Steps

1. Confirm the signal person knows and understands the type of signals being used and is competent in applying them.
2. Confirm qualification was established through one of the two allowed paths: third-party qualified evaluator documentation, or the employer's own qualified evaluator assessment, per 1926.1428.
3. If relying on the employer's-evaluator option, confirm the documentation is not treated as portable to another employer — a new employer must re-qualify the signal person under its own evaluator or a third party.
4. Verify the employer completed this qualification determination before the signal person gives any signals, not retroactively.
5. Keep the qualification documentation available at the site for as long as the signal person is employed there.
