Electrical Safety Guidelines and Warnings

In Case of Electrical Accident

If an electrical accident results in an injury, take the following actions in this order:

  1. Use caution. Be aware of potentially hazardous conditions that could cause further injury.
  2. Disconnect power from the services gateway.
  3. If possible, send another person to get medical aid. Otherwise, assess the condition of the victim, then call for help.

General Electrical Safety Guidelines and Warnings


Certain ports on the services gateway are designed for use as intrabuilding (within-the-building) interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 4) and require isolation from the exposed outside plant (OSP) cabling. To comply with NEBS requirements and protect against lightning surges and commercial power disturbances, the intrabuilding ports must not be metallically connected to interfaces that connect to the OSP or its wiring. The intrabuilding ports on the switch are suitable for connection to intrabuilding or unexposed wiring or cabling only. The addition of primary protectors is not sufficient protection for connecting these interfaces metallically to OSP wiring.

  • Install the services gateway in compliance with the following local, national, or international electrical codes:

    • United States—National Fire Protection Association (NFPA 70), United States National Electrical Code

    • Canada—Canadian Electrical Code, Part 1, CSA C22.1

    • Other countries—International Electromechanical Commission (IEC) 60364, Part 1 through Part 7

    • Evaluated to the TN power system

  • Locate the emergency power-off switch for the room in which you are working so that if an electrical accident occurs, you can quickly turn off the power.

  • Do not work alone if potentially hazardous conditions exist anywhere in your workspace.

  • Never assume that power is disconnected from a circuit. Always check the circuit before starting to work.

  • Carefully look for possible hazards in your work area, such as moist floors, ungrounded power extension cords, and missing safety grounds.

  • Operate the services gateway within marked electrical ratings and product usage instructions.

  • For the services gateway and peripheral equipment to function safely and correctly, use the cables and connectors specified for the attached peripheral equipment, and make certain they are in good condition.
