Lightning Safety for Outdoor Athletes If thunderstorms develop, count the seconds between the flash of lightning and the bang of the thunder to estimate the distance between you and the lightning strike. Because sound travels at approximately 1 mile in 5 seconds, you can determine how far away the lightning is by using this flash-to-bang method. It is recommended that you seek shelter if the time between the lightning flash and the rumble of thunder is 30 seconds or less (6 miles). Once inside shelter, you should not resume activities until 30 minutes after the last audible thunder. This is known as the 30/30 Lightning Rule.

Flash Facts About Lightning Although some victims are struck directly by the main lightning stroke, many victims are struck as the current moves in and along the ground. • If you can hear thunder, you are within 10 miles (16 kilometers) of a storm—and can be struck by lightning. Seek shelter and avoid situations in which you may be vulnerable. • Use the 30-30 rule, when visibility is good and there is nothing obstructing your view of the thunderstorm. When you see lightning, count the time until you hear thunder. If that time is 30 seconds or less, the thunderstorm is within six miles (ten kilometers) of you and is dangerous. Seek shelter immediately. The threat of lightning continues for a much longer period than most people realize. Wait at least 30 minutes after the last clap of thunder before leaving shelter.

lightning strikes a tower 4 km away. how long after the strike will you hear the thunder? the speed of sound is 344 m/s If you hear thunder 36 seconds after you see a flash of lightning how far away is the thunderstorm? About 12 kilometers (7.45 miles). After you see a bolt of  lightning, for every 3 seconds until you hear the thunder, it means  it is one kilometer away (3 seconds = 1 kilom…eter). This is because  the sound wave created by the lightning is traveling at about 330  m/sec (in dry air, the speed of sound is about 343 m/sec or 1127  ft/sec).    You can also divide by 5 to determine the approximate number of  miles. In this case it would be calculated as about 7.2  miles away.

How Long Does Your Heart Have to Stop For Before You Can't Be Treated? 20 minutes is a common time frame. Vasopressin takes approximately 20 minutes to begin to cause a reaction. A rescuer would need to continue attempting resuscitation for at least that long before they would expect a result. 20 minutes would then be the minimum amount of time you would attempt resuscitation. Some would continue longer, especially if they had a change in the electrical function of the heart.

What exactly happens during the 7 minutes of brain activity after death'? Unconsciousness occurs within about 30 seconds, so it's not as if you would have very much time to contemplate what is happening. Once the brain goes unconscious, tissue begins to die after about 5 minutes of oxygen starvation. After this point, there may only be small islands of activity remaining in various brain structures. After ten to fifteen minutes, complete brain death will usually occur. One exception to this is if the brain (and body) are in a state of hypothermia. Extreme cold can induce a process called neuroprotection; metabolism is greatly reduced, and the brain can survive for much longer than it would at room temperature.
