[header] How to give first aid to an electrocuted animal [title] Remove the electrical source. [step] Before touching your pet, turn off or remove the source of electrocution. This will involve unplugging the electrical cord from the electrical socket and/or shutting off the electricity. <sep> (A) [substeps] The electrical cord wrapped around the electrical socket may be part or all of the animal's body. These will be treated separately from the rest of the animal. (B) [substeps] It may be possible to take your pet outside for this step. But be sure to call your veterinarian before doing this. (C) [substeps] Use a wooden broom handle to gently move your pet away from the electrical source. A wooden broomstick is ideal because it would not conduct an electrical current that would shock you. (D) You will still have to make sure to perform an indirect shock first. [title] Place the animal on a vinyl or glass surface.

[header] How to cope with a staff shortage [title] Cut back on inventory. [step] You may already have a balanced budget. However, try reducing your spending even more. <sep> (A) The extra cuts in expenditures may save you a nice sum of money. After all, spending less is a safer bet than taking chances on turning a record profit. (B) When learning an employee's finances, that in turn hurt your own. Many importantly, you should try to avoid starting cravings for food whenever possible. (C) This can minimize how much inventory you collect, especially in smaller-scale places. [substeps] For example, cut out three or four salons and one of them produces less inventory than the other three or three.

This can cause you to spend your savings on high-value products.

[header] How to clean a wood fence [title] Cover the ground around the fence with plastic. [step] If you have plants you care about or you decide to use a chemical cleaner, you'll want to cover the area around the fence with plastic. Go to your local hardware store and purchase enough plastic sheeting to cover the plants and grass up to at least 3 feet (0.91 m) from your wood fence. <sep> (A) [substeps] Lightly tap the plastic all over the area. Use an electric drill to separate the plastic from the wood and add it to the ground. (B) [substeps] Avoid insulating your fence area with plastic sheeting. This does not give the chemical cleaner a chance to seep down through the plastic and into the ground. (C) [substeps] At minimum, cover the entire fence with plastic, especially when it rains. Leave at least an inch of excess plastic at the bottom for drainage. (D) [substeps] Purchase just enough plastic for one section and move it with you when you move to the next to save money.
