Also notice that the magnetic north pole is located near the southern polar axis and the magnetic south pole is located near the northern polar axis. The reason that the geographicpoles (axes) are called north and south is because the north pole of a compass needle points in the direction of the north geographic pole.

MSDS stands for material safety data sheets, which are provided with many products. They generally warn users of any hazards associated with the product. They outline the physical and chemical properties of the product; list precautions that should be taken when using the product; and list any potential health hazards, storage consideration, flam-mability, reactivity, and, in some instances, radioactivity. They sometimes list the name, address, and telephone number of the manufacturer; the MSDS date and emergency tele-phone numbers; and, usually, information on first aid procedures to use if the product is

Currents from 100 to 200 milliamperes generally cause death because the heart usually goes into fibrillation, a condition in which the heart begins to “quiver” and the pumping action stops. Currents above 200 milliamperes cause the heart to squeeze shut. When the current is removed, the heart usually returns to a normal pumping action.

Work with One Hand When PossibleThe worst kind of electric shock occurs when the current path is from one hand to the other, which permits the current to pass directly through the heart. A person can survive a severe shock between the hand and foot that would cause death if the current path were from one hand to the other.

Of all the rules concerning safety, this one is probably the most important. No amount of safeguarding or idiot proofing a piece of equipment can protect a person as well as taking time to think before acting. Many technicians have been killed by supposedly “dead” cir-cuits. Do not depend on circuit breakers, fuses, or someone else to open a circuit. Test it yourself before you touch it. If you are working on high-voltage equipment, use insulated gloves and meter probes to measure the voltage being tested. Think before you touch some-thing that could cost you your life.
