.The following comments are incomplete - other safety concerns and advice may apply, pending additional technical review by industry experts.

  1. If you are having an emergency right now such as seeing smoke or fire you should get occupants out of the building and call the fire department. This is a general suggestion for any suspected building fire, and is not unique to Zinsco, Sylvania, or any electrical product manufacturer.
  2. Do not touch the electrical panel if you are standing on a wet floor.
  3. Warning of possible fatal electrical shock: If you have noticed any of the trouble signs listed in the next section below, or if you already know that you have problem electrical equipment such as the Zinsco components discussed here, have a qualified electrician inspect the electrical system.

    Where problems have been observed (such as flickering lights), the electrician can determine the cause of the problem and recommend the appropriate repair.
    Also see ELECTRIC POWER LOSS / FLICKERING LIGHTS- causes of flickering or dimming lights
  4. Do not disassemble electrical equipment nor try to make electrical repairs yourself: You could be electrocuted or you could make the electrical equipment more unsafe by disturbing it.

    Although this website includes photographs of the interior of electrical panels, you should not try to see inside the electrical panel by removing screws to take off the cover yourself as this can be quite dangerous.
  5. Identify the electrical panel: Determine whether or not you have Zinsco or Sylvania-Zinsco electrical equipment installed by simple visual inspection of the electrical panel exterior, any exposed labels or markings, and by observing the characteristic red and blue-colored circuit breaker toggle switches.

    See IDENTIFY ZINSCO ELECTRICAL PANELS.
  6. Flickering lights? Pending replacement of unsafe electrical panels and circuit breakers of any brand, turn off any suspect circuits such as ones displaying flickering lights.
  7. Be sure that you have working smoke detectors in your home.
  8. Turn off unsafe or suspect electrical equipment. If there is evidence of or suspicion of overheating electrical devices turn off the offending electrical circuit or turn off all electrical power.
  9. Hire a professional who knows the issue: To inspect the electrical panel, to confirm that you have unsafe electrical equipment, and to replace unsafe electrical equipment in a home, you should hire a licensed electrician who is familiar with Zinsco/Sylvania equipment and the hazards it poses.
