Safety Precautions
The ARRL Safety Code

• Unplug everything you plan to work on before
  touching anything behind or inside the radio.
• Never let anyone turn the power on and off for
  you when you are working on a radio.
• Dont work on a radio when you are tired or
  sleepy. Dont work alone.
• Never adjust internal electrical components by
  hand use the proper plastic or insulated tools.
  Be sure the insulation is in good condition.
• Dont touch grounded metal (like radiators or
  water pipes) or wet floors when you are working
  on radio equipment. You can get a dangerous
  shock even if the equipment is grounded, through
  ground loops between different ground points.
• Never wear headphones while working on radios.
• Always keep one hand in your pocket when working
  on radios. That way, if you do touch a hot
  point, the electricity cannot travel across your
  chest and cause a heart attack.
• Tell your family how to turn the power off and
  how to give artificial respiration. Be sure you
  are up-to-date in first aid.
• Develop your own safety techniques. Take the
  time to be careful death is permanent.
