-- We were also given a written safety brief with the following highlights.

     1.) Do not work alone on energized components
     2.) Switch off all power when assembling an experiment or project
     3.) Keep one hand behind your back and use an insulated probe whenever measuring an energized
          circuit.
     4.) Never work on electrical equipment when you have wet hands or are standing on a wet floor.
     5.) Never touch two pieces of equipment simultaneously
     6.) Never lunge for or attempt to cut falling parts of a live circuit

-- Another Part of the Safety Briefing discussed the danger of electrical current. Unlike Voltage a
    very small amount of current can be lethal.

   - A current as small as 0.01 Amps can be cause a painful shock, muscle paralysis and labored
        breathing
   - A current of only 0.1 to 0.2 Amps is known as the lethal current and can stop your heart
   - Currents of 1 Amp or Greater are more violent and cause a severe burn and leads to death
        by asphyxiation caused by muscular paralysis of the lungs and diaphragm.
