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 30 minutes.


  • If you can see it (lightning), flee it;
  • if you can hear it (thunder), clear it.

Associated Hazards

  • Contrary to popular belief, most lightning accidents do not come from direct lightning strikes.  There are several ways lightning can cause injury.


  • COMMUNICATIONS
10
Tactical Communications
  • 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.
11
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).
16
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.
17
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.
18
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 6 feet away from the tree trunk to minimize a side strike and step voltage.  NEVER stand under an isolated tree.
19
Safe Locations #3 (cont’d)
  • 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.
20
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

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