We studied the prevention of water accidents, the rescue of those who couldn’t get back to safety and the use of various types of equipment, including boats, ring buoys, bamboo poles and inner tubes.

We extended the bamboo pole when the victim was too far out to reach with a device called a "shepherd’s crook," which was heavier and more expensive than bamboo, On shore, we coiled a rope like a lasso, stood on one end and slung the other end out to pull a tired swimmer to safety. We also practiced using wooden objects such as a chair, plank, log, ladder and even a farm gate because wood floats.

What value is a boat, ring buoy or shepherd’s crook if they are not within running distance of the scene of the emergency? A swimmer who can’t get air will likely suffer permanent damage in three minutes! There is no time to go far for devices and no time for rescue crews to arrive in time to save the life.

Ten years after that aquatic school experience, one of my college students brought me a photo from a Florida paper. A man was hanging onto the spare truck wheel that had floated out of the back of his pickup when it was washed off the road in a flash flood.

That photo completely changed my way of evaluating lifesaving equipment. A life was saved because a spare tire floated.

In almost every drowning situation, some kind of vehicle with a spare wheel is within running distance of the site.

Drownings happen without warning. When someone is unable to get to safety alone, it is advisable even for good swimmers to scream "help" instead of attempting a rescue. Even a best friend might become a wild, vicious animal when he or she is fighting for one last breath!

People trained in lifesaving know how to defend themselves and how to release strangleholds, but others should have a rescue device on shore, just in case.

There is such a device in almost every automobile. The spare tire and wheel will float if it has air and can support several people at a time.

I know of no other rescue device that equals the spare tire because:

● The rescuer is not danger.

● It can support an unconscious victim.

● All the occupants of a boat or canoe can rest on the wheel while waiting for other rescue.

● There are millions of inflated spare tires.

You can read that a heavy spare wheel, metal and all, will float, but you’ll believe it if you try it out.

Put a wheel in a lake, pond, pool or horse trough and try to push it underwater. Then you’ll join me and an army of others who know that the spare wheel is "the greatest rescue device known."

If every reader would try this and tell others, we will probably save at least one more life this summer - maybe even the life of a loved one.
