Why Do We Need to Be Careful at Tall Building Construction Site?
There are thousands of accidents at construction sites involving different electric shocks every year. Around thirty of these cases involve lightning strike, and most of them are fatal. Lightning strikes can occur when you least expect it. Sloppy mind can lead to serious consequences, sometimes even death. That is why you must be very careful when you are constructing on a tall building site.
How do I Know a Lightning Strike is Coming?
Most countries including US and China have adopted a five-scale (Red, Orange, Yellow, Blue, and Green, from dangerous to safe) warning system. In China, Local weather bureau will issue a warning of lightning strike though SMS or app pushing, after weather radar has detected a possible coming thunderstorm. If you receive this message, it will leave you hours of time enough for unhurried preparation.
If you have missed this weather forecast (which most people do), bear in mind that lightning always come with thunderstorms. The threat of lightning starts when a thunderstorm closing in, peaks when the storm is overhead, and then gradually vanishes as the storm moves away. If you are at the top of a tall building construction site and see thunderstorm coming, you need to leave immediately, because the evacuation window may be closing in a few minutes.
If you still are not leaving, you may soon feel hair standing up on end. This means a lightning will strike you within seconds.
How to Avoid Lightning Strikes on Tall Building Construction Site
1. Hours before lightning strike
If you have protective shoes and clothing, wear them immediately. You may also wear non-conductive gloves and professional body suits, to make sure you stay protected as safe as possible. If you do not have it, back to the indoors and await further instruction. If you have received Red or Orange warning from local agency, stop working and get down immediately.
2. Minutes before lightning strike
If you have already seen a large thundercloud and start hearing thunder or smelling ozone (like swimming pool), stop everything and run as fast you can down the building.
3. Seconds before lightning strike
Quickly scan your surrounding for enclosed structures like a temporary hut or container. Run for it with all your strength. If it is nothing there, start running and jumping, then pray for miracle to happen.
