What should be done if you hear thunder within 30 seconds of a lightning strike?

When thunder is heard within 30 seconds of a lightning strike, it indicates that lightning is nearby and poses a direct threat. The correct action is to shut down outdoor equipment, such as generators, as a safety measure, and to wait at least 30 minutes after the last strike before resuming outdoor activities.

The rationale behind shutting down the outdoor generator and waiting is based on protocols for lightning safety. Lightning can cause injury or damage if individuals remain in exposed areas or continue to operate electrical equipment that is not designed to withstand a lightning strike. By shutting down equipment, you minimize risk and create a safer environment.

The recommendation to wait 30 minutes post-strike is important because lightning activity can persist even after a storm has seemingly passed. This waiting period helps ensure that the immediate threat has subsided before resuming outdoor work or activities. Additionally, it’s a widely recognized guideline among safety authorities when it comes to lightning storms.

While it is also important to alert others nearby to take cover and seek safety, the primary action that directly addresses your own safety and the safety of ongoing operations during a lightning storm involves shutting down equipment and waiting.
