or hot metal that could cause a fire later. Use fire watchers when necessary.
2.1.4 ELECTRICAL SHOCK
Therefore:
1. Be sure the power source frame (chassis) is connected to the earth system of the
input power. All ground points should be verified with periodic testing by an
electrician.
2. Connect the workpiece to a good electrical earth.
3. Connect the work cable to the workpiece. A poor or missing connection can expose
you or others to a fatal shock.
4. Use well-maintained equipment. Replace worn or damaged cables.
5. Keep everything dry, including clothing, work area, cables, torch/electrode holder
and power source.
6. Make sure that all parts of your body are insulated from both the work piece and
from the ground.
7. Do not stand directly on metal or the ground while working in tight quarters or a
damp area; stand on an effective insulation layer, such as dry boards, an insulating
platform, and wear rubber-soled shoes.
8. Put on dry, hole-free gloves before turning on the power.
9. Turn off the power, before removing your gloves.
10. Refer to ANSI/ASC Standard Z49.1 for specific grounding recommendations. Do not
mistake the work lead for an earth cable.
