(3) Ground electrical soldering irons and guns when feasible and in accordance
with the "National Electrical Code" handbook. Grounding will minimize the danger of electrical
shock resulting from defective equipment. It will also reduce the danger of the soldering
equipment producing a spark in explosive areas. Grounding will also protect semiconductor
devices by neutralizing any differences in potential between the soldering equipment and the
semiconductors in transistor equipment.
(4) Do not flip excess solder from the tip of a hot soldering iron. Bits of hot
solder can cause serious skin and eye burns; they may also ignite combustible materials.
(5) Do not handle hot metals; allow the pieces to cool before handling.
(6) Select the proper working area for soldering. Choose a well-ventilated
location away from all fire hazards.
(7) Mechanically secure large workpieces while they are being soldered. Severe
injuries or burns may be received because of a falling workpiece.
(8) Wear the proper clothing and protective devices while soldering.
(9) Maintain a clean working area to prevent fires. Remove combustible materials
from the floor and from the surrounding area.
(10) Keep fire-fighting devices and first-aid supplies near the soldering area. All
equipment should be checked at regular intervals.
a) When personnel are subjected to direct lightning strikes, the results are nearly
always fatal. Although extraordinary escapes from direct strikes have been reported, the shock is
so great that survival is rare. The major portion of lightning casualties arise from secondary
effects, such as side flashes and induced charges.
First-aid treatment, especially artificial respiration or cardiac-pulmonary
resuscitation, may prevent death from any but direct charges.
b) The following rules for personnel safety should be observed during any
(1) Remain indoors unless absolutely unavoidable. Stay within a dry area of the
building, preferably away from all metal objects.
(2) If there is a choice of shelter, select a suitable shelter such as: large metal or
metal-frame buildings, buildings which are protected against lightning, or vehicles.
(3) If remaining out-of-doors is unavoidable, keep away from:
