it. Swinging wires of any kind may somewhere in their course be in contact with live wires, so they should not be touched.

A person in contact with a wire or rail carrying an electric current will transfer the current to the rescuer. Therefore he must not touch the unfortunate victim unless his own body is thoroughly insulated. The rescuer must act very promptly, for the danger to the person in contact is much increased the longer the electric current is allowed to pass through his body. If possible, the rescuer should insulate himself by covering his hands with a mackintosh, rubber sheeting, several thicknesses of silk, or even dry cloth. In addition he should, if possible, complete his insulation by standing on a dry board, a thick piece of paper, or even on a dry coat. Rubber gloves and rubber shoes or boots are still safer, but they cannot usually be procured quickly.

If a live wire is under a person and the ground is dry, it will be perfectly safe to stand on the ground and pull him off the wire with the bare hands, care being taken to touch only his clothing, and this must not be wet.

A live wire lying on a patient may be flipped off with safety with a dry board or stick. In removing the live wire from the person, or the person from the wire, do this, with one motion, as rocking him to and fro on the wire will increase shock and burn.

A live wire may be safely cut by an axe or hatchet with dry, wooden handle. The electric current may be short circuited by dropping a crow-bar or poker on the wire. These must be dropped on the side from which the current is coming and not on the farther side, as the latter will not short circuit the current before it is passed through the body of the person in contact. Drop the metal bar; do not place it on the wire or you will then be made a part of the short circuit and receive the current of electricity through your body.

What To Do for Electric Shocks

Always send for a doctor, but do not wait for him. Treatment should be given even if the man appears to be dead. Loosen the clothing around neck and body. Proceed to restore breathing by artificial respiration as in drowning. (See pages 286, 287.)

Gas Accidents

The commonest gas encountered is the ordinary illuminating gas. To prevent such gas from escaping in dangerous quan-
