Kills more than Hurricanes and Tornadoes combined!
• Kills ~ 100 / Year
• Kills ~ 10% of those Struck
2nd Leading Cause of Weather Deaths in the United States

Lightning Safety when Outdoors
If you can see lightning or hear thunder, activate your safety plan. Resume activities only when lightning and thunder have not been observed for thirty minutes.
If you can see it (lightning), flee it; if you can hear it (thunder), clear it.

Lightning Safety
• “30 / 30 Rule”
• If 30 Secs Or Less “Flash To Bang”- Seek Shelter
COMMON MISCONCEPTION
1 second = 1 mile
ACTUALLY
5 seconds = 1 mile
• Wait 30 Min After Last Lightning, Before Leaving Shelter
May Seem Too Conservative--It’s NOT!

Lightning Safety
• Important Components Of A Dispersal/Safety Plan
• Designated individual responsible to monitor the weather and initiate the necessary precautions when appropriate.
• Procedure identified to notify all personnel of the appropriate actions when there is a threat or risk of lightning.
• Safer locations must be pre-identified along with a means to route personnel to those locations.
• Establishment of an “All Clear” signal which is differentiated from the warning signal.
• Periodically Review / Train / Drill Dispersal Plan

Associated Hazards
Contrary to common belief, most lightning accidents do not come from direct lightning strikes. There are several ways lightning can cause injury.
COMMUNICATION
![Page 10: Lightning Safety Fort Detrick Installation Safety Management Office (301) 619-7318](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649dc95503460f94abfc15/html5/thumbnails/10.jpg)
Tactical Communication
• Equipment will be grounded IAW grounding instructions contained in applicable TMs. Remember that soil type impacts the grounding.
• Keep away from antennas, masts, guy wires and all grounding and lightning protection equipment, including ground rods, during electrical storm activity. This includes vehicles with whip antennas.
![Page 11: Lightning Safety Fort Detrick Installation Safety Management Office (301) 619-7318](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649dc95503460f94abfc15/html5/thumbnails/11.jpg)
Tactical Communication
• If mission permits, disconnect the signal inputs before the storm. Do not attempt this during the storm, even if lightning is not nearby!
• Restrict the use of telephones, computers and other electrical devices. Lightning could follow the wire. Most lightning injuries occur from using phones during electrical storms.
• Radios will not be used, nor will troops carry radios with antennas extended.

Safe Locations #1
• No place is absolutely safe from lightning. Ideally, evacuation to a lightning certified or lightning protected building is the best when available; however, this will probably not be the case.
THEN
• Large enclosed structures (substantially constructed buildings).
![Page 16: Lightning Safety Fort Detrick Installation Safety Management Office (301) 619-7318](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649dc95503460f94abfc15/html5/thumbnails/16.jpg)
Indoor Lightning Safety
• Avoid using telephone (remember the wires).• Avoid using water – sink, tub, etc. (plumbing)
• Unplug appliances (remember the wires).
• Inner rooms the best.
![Page 17: Lightning Safety Fort Detrick Installation Safety Management Office (301) 619-7318](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649dc95503460f94abfc15/html5/thumbnails/17.jpg)
Safe Locations #2
• Fully enclosed metal vehicles – car, bus, etc.– Close windows– Keep hands on lap
It’s not the rubber tires that make a vehicle safe – it’s the metal enclosure.
Not Canvas Type (soft) TopsSo, what does this say aboutUsing 2 ½ and 5 ton vehicles?

Safe Locations #3
• Remaining Outdoors– Stay away from rivers, lakes, or other bodies of water.
Be aware of the potential for flooding in low-lying areas.
– Stay away from natural lightning rods/tall structures such as: towers, tall trees, telephone poles/lines, tents with metal supports, etc.
– Take shelter under a small tree among several large ones if possible. Stay at least six feet away from the tree trunk to minimize a side strike and step voltage. NEVER stand under an isolated tree.
![Page 19: Lightning Safety Fort Detrick Installation Safety Management Office (301) 619-7318](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649dc95503460f94abfc15/html5/thumbnails/19.jpg)
Safe Locations #3 (con’t)
• Stay low (crouch) in a ditch or depression. Other options include a low area, ravine, or foot of a hill. DO NOT lie flat on ground.
• Weapons should be stacked at least 50 meters away from personnel.
• Miles gear and other metal conductors should be removed.
![Page 20: Lightning Safety Fort Detrick Installation Safety Management Office (301) 619-7318](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649dc95503460f94abfc15/html5/thumbnails/20.jpg)
Lightning Safety Position (LSP)
• Assume LSP.Crouch with feet as close
together as possible. Have heels touch.
Place hands over ears.
-REMEMBER- DO NOT LIE FLAT ON THE GROUND

Seek Proper Shelter
• Buildings Much Better Than Vehicles
• Large, Fully Enclosed, Substantially Built
• Vehicles Offer Some Safety
• No Place Outside Is Safe Near A Thunderstorm
• Near 6 Miles

Lightning Safety
Without soldiers, civilians and equipment we can not support our mission – protect these valuable assets.
