Rescue Techniques

Use of Levers and Jacks

When buildings collapse, people are frequently pinned under falling debris. Often this debris is too heavy to lift by hand. You must, therefore, be able to use levers and jacks.

A lever is a device that gains power by sacrificing distance. Any sturdy piece of wood or metal will make a lever. Any solid object, such as a piece of masonry, makes a good fulcrum. Learn to improvise.

Make sure the fulcrum is placed so it won't sink under pressure. If necessary provide a wider base by putting the fulcrum on a board that will spread the load on the ground. If the load slips or your lever collapses, the victim may be injured further or killed. Always work from a secure position, keeping both feet on the ground. The safest way to use a lever is to make a short lift at a time and, for safety, shore up the progress as you go.

A jack is a mechanical device designed to lift heavy loads. You can use it in a more confined space than a lever. But it also needs care and practice to be used safely.

WARNING! When using levers and jacks-DO NOT use metal against metal. This could create sparks and trigger a fire or explosion. Use rags or wood to prevent sparks and slippage.
