Hammers

Use only hammers that are in good condition with handles firmly attached. Repair or replace hammers with

defective handles or mushroomed heads. If the head has mushroomed, dress it prior to using it. When

repairing a handle, never use nails as a substitute for a wedge.

Always grip the handle close to the end. Choking the grip near the head is less accurate and effective.

Set nails with a light blow to minimize the possibility of finger injuries.

Always use a hammer with a flat face to drive nails, never use a machinist's hammer for this purpose.

Never pound objects with the hammer's handle.

To prevent flying metal splinters, never strike a hardened object such as a wrench or another hammer with

anything but a rawhide or soft-metal hammer.

Wrenches

• Keep all pipe wrenches clean and in good repair. Use a wire brush frequently to clean the jaws of pipe

wrenches. An accumulation of dirt and grease can cause wrenches to slip.

• Use a wrench of adequate size, a larger wrench is safer than using a cheater pipe.

• If using an adjustable wrench, note that the fixed jaw is stronger than the movable one.

• If possible, pull on a wrench using your arm muscles rather than push on it.

• Maintain good footing, one foot bracing behind the other, when using a wrench. Remove sharp objects

from the area in case of a fall.

• Position your hands so they will not be crushed or smashed if the nut or joint releases.

• Never apply a wrench to moving machinery.

• Never use a wrench as a hammer.

• Wire brush the jaws of pipe wrenches frequently, and replace worn jaws periodically.

• Use wrenches - not pliers - on nuts.

• Never use pipe wrenches in place of a rod holding device.

• Replace hook and heel jaws when they become visibly worn.

• When breaking tool joints on the ground or on a drilling platform, position your hands so that your

fingers will not be pinched between the wrench handle and the ground or the platform if the wrench

should slip or the tool joint suddenly let go.

• When using a wrench on a tight nut: first use some penetrating oil, use the largest wrench available that

fits the nut, when possible pull on the wrench handle rather than pushing, and apply force to the wrench

with both hands when possible and with both feet firmly placed. Do not push or pull with one or both

feet on the drill rig or the side of a mud pit or some other blocking-off device. Always assume that you

may lose your footing -- check the place where you may fall for sharp objects.

• Never use a cheater bar on an aluminum pipe wrench

Screwdrivers

Always use a screwdriver that closely fits the screw slot.

Never use a screwdriver with a worn, chipped, or broken tip.

Never use a screwdriver as a substitute for a chisel or pry bar.

Keep cutting tools sharp.

If an accident occurs, treat all cuts and scratches immediately with simple first aid measures to prevent

infection, which can occur in a matter of hours.
