Any “No” means the scaffold is not handed over: red tag it, fix it, then inspect again.

Based on TG20:21, TG30, SG35-style inspection practice, BS EN 12811-1 and the Saudi Aramco Construction Safety Manual. Not endorsed by any of them. Verify against the latest edition and the scaffold’s own design.
