Humorous Stories and What We Learn

Story 1: The Case of the Missing Bolts

A construction crew was assembling a steel bridge when they realized they were missing several bolts. They searched everywhere but couldn't find them. Finally, they checked the blueprints and discovered that the bolts had been omitted from the design. The lesson: always double-check the plans!

Story 2: The Crane that Fell Asleep

A construction site was using a massive crane to lift heavy steel beams. However, the crane operator accidentally fell asleep, and the crane slowly tipped over, narrowly missing the workers below. The lesson: never operate heavy machinery when tired!

Story 3: The Steelworker who Lost his Phone

A steelworker was working on a high-rise building when he dropped his phone off the scaffolding. It landed in a bucket of molten steel. The lesson: always keep your valuables secured when working at heights!
