Hi, This presentation is great. I need to protect my communication tower and the communication equipment inside from lightning. Asking your permission to download the file. Thanks a lot.

Dear Sir , May I request you to permit me the use of this wonderful presentation. I work in a lightning prone environment and this education tool will be immensely beneficial. Regards, Mann

I teach 5th grade and would be interested in using parts of your presentation to teach safety as part of a unit on electricity and magnatism.

See all

Lightning Safety : 

Lightning Safety Fort Detrick Installation Safety Management Office (301) 619-7318

Lightning Safety Websites: 

Lightning Safety Websites This presentation was compiled by First Army from information provided on the following websites. 45th Weather Squadron Lightning Safety Website: http://www.patrick.af.mil/45og/45ws/LightningSafety/index.htm NOAA Lightning Safety: http://www.lightningsafety.noaa.gov/ CECOM Publications (Antenna Safety, Grounding, etc.) http://www.monmouth.army.mil/cecom/safety/SYSTEM/SPUB.HTM Kids’ Lightning Information and Safety: http://www.azstarnet.com/anubis/zaphome.htm

Slide3: 

Lightning Facts 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

Slide4: 

Survivors are an even greater tragedy! Injures ~750 / Year ~ 70% Long-Term Medical Problems ~ 30% Suffer Debilitating Problems Elusive Data 40 - 70% Under-Reported Lightning Facts

Slide5: 

When thunderstorms nearby, avoid these activities like your life depends on it -- It Does! Lightning Facts

Lightning Safety when Outdoors: 

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.

Slide7: 

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!

Slide8: 

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: 

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

Tactical Communication: 

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.

Tactical Communication: 

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.

Lightning Step Voltage: 

Lightning Step Voltage 200,000 Volts 0 Volts far away Current flow thru earth generates voltage 8,000 volts across feet (Typical) Step Voltage KMS: 5/98

Safe Locations #1: 

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).

Indoor Lightning Safety: 

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.

Safe Locations #2: 

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) Tops So, what does this say about Using 2 ½ and 5 ton vehicles?

Safe Locations #3: 

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.

Safe Locations #3 (con’t): 

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.

Lightning Safety Position (LSP): 

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

Slide21: 

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 Safe Locations

Lightning Safety: 

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