Hand tools are easy and safe to use when they are used properly. Please
inform yourself about safe use of hand tools by reading ahead, and by
consulting with your teacher or mentor. Below, we describe some commonly
used hand tools and some dangerous situations that can result if they are
not used properly.

Safety Glasses
|
|
Safety glasses, the most important safety aid, are inexpensive, and
available at any hardware store, or from your shop teacher.

Hot Glue Gun
|
Very useful for quickly fastening different materials together with a
reasonably strong bond, hot glue guns can cause minor burns
if the gun nozzle or hot glue touches the skin.
Store tools safely.
Unplug electrical tools when not in use for a long period of time.

Soldering Iron

Electric Hand Drill
|
Hand drills are useful for placing holes in materials, and might be
used in the fabrication of wheels, for example.
- Wear safety glasses. If too much force is applied, drill bits
can break, launching fragments into the air. Material removed
by the drill bit can also become airborne. Students using
hand drills should work a safe distance from students that are
not wearing safety glasses.
- Clamp work securely. A spinning drill bit can
grab the workpiece and yank it around if it is not properly
clamped in place, resulting in hand injuries, especially if
the workpiece has sharp edges. A small vice or clamp is used
for this purpose.
- Note what is underneath the piece being drilled.
Be sure that the drilling is done into a secure block of scrap wood or
into clear space.
- Store tools safely.
Unplug electrical tools when not in use.

Hacksaws & Jigsaws
|
Hacksaws & jigsaws are useful for cutting a variety of materials.
- Wear safety glasses. Removed material could
become airborne.
- Clamp work securely. This removes any
inclination to hold the workpiece near the cutting zone, and
allows better control of the tool. A small vice or clamp is
used for this purpose.
- Note what is underneath the piece being cut.
Be sure that the cutting is done into a clear space.
- Keep hands away from the cutting zone.
The blade can jump and cause minor hand injuries.
- Store tools safely.
Unplug electrical tools when not in use.

Wire Clippers
|
These tools are useful for cutting wire and thin shafts. If both sides
of the piece are not securely held, they may shoot out.
- Wear safety glasses. The material could
become airborne.
- Clamp work securely. Clamping one or both ends
of the material being cut with a pair of pliers or clamp reduces
the chance of a piece becoming airborne. Orient the tool so that
any loose piece is aimed at the floor.

Utility or "Exacto" Knives
|
Useful for cutting cardboard, foam, balsa wood etc.
- Wear safety glasses. A blade could break and
fly upwards.
- Cut away from yourself. Do not direct the blade
toward any part of your body or other hand as a simple slip can
cause a minor cut.
- Store tools safely.
Avoid leaing exposed blades on table surfaces. Use a handle with
a retractable blade if possible.
