It’s dangerous for construction workers to hold a long steel pole upright during lightning because steel is an excellent conductor of electricity. If lightning strikes, the metal pole would act as a direct path for the electrical current to travel through the worker’s body. This could result in severe injuries or death due to electrical shock.
Additionally, holding a steel pole during a thunderstorm increases the likelihood of attracting lightning, as tall, conductive objects like steel poles are more likely to be struck. The pole’s height makes it a potential lightning rod, and since lightning often strikes the tallest objects in a given area, the worker would be at greater risk. For safety, it’s crucial to avoid holding or being near tall metal objects during thunderstorms.
