UIS Physical Planning and Operations Emergency Response Lightning Safety back to severe weather back to a-z index

Approved June 25, 2003

Although hurricanes and tornadoes receive most of the recognition, lightning occurs most often in the United States.  Over 40 million lightning strikes occur every year, which results in nearly 100 deaths.  This number is an underestimate of the actual number of casualties because of the underreporting of suspected lightning deaths and injuries. (NOAA)

Each year, more people are killed by lightning than by tornadoes. Most deaths occur in open fields (ballfields) and under or near trees. Lightning in Illinois in the past 40 years has killed ninety-six people. In 2001, Illinois ranked second in the United States for lightning fatalities. (IEMA)

In order to assure the health and safety of the Physical Planning and Operations staff during severe thunderstorms, involving lightning, the department safety committee developed lightning safety guidelines for employees working outdoors. The following guidelines have been approved by the PPO Safety Committee and the PPO Director on June 25, 2003. These guidelines have been added to the university’s Emergency Action Plan.

Suspend Activities – Evacuate

When working outdoors, if you can see lightning or hear thunder, all outdoor activities must cease. (IEMA). All employees must seek appropriate shelter and report to their designated supervisor(s) for further instructions.

Monitor Conditions

An NOAA weather radio will be provided to the PPO staff to monitor current weather conditions. The radio will be located in the PPO Shop Grounds break room.

Resume Activities

Resume outdoor activities only when lightning and thunder have ceased.
