    Study Notes

    Lockout/Tagout and Electrically Safe Work Condition Procedures

    • Tagout is defined as installing a tagout device on hazardous energy sources to prohibit operation of disconnecting means.
    • If locks cannot be attached to existing disconnecting means, alternative means must be employed to ensure electrical safety.
    • Tagout without a lock is allowed only if equipment design prevents lock installation, with additional safety measures required.
    • Responsibilities and accountability for individuals exposed to electrical hazards during tagout procedures must be clearly established.
    • Procedures must detail how to remove lockout/tagout devices when the installer is unavailable and inform the installer before returning to work.
    • Steps to be taken upon completion of a task requiring lockout/tagout, including tests, inspections, and notification of responsible employees.
    • Clear identification of steps and responsibilities when a lockout/tagout task is temporarily interrupted for testing or positioning of equipment.
    • The process for establishing and verifying an electrically safe work condition, including steps to be performed in order.
    • Use of portable test instruments to test for the absence of voltage at each point of work, or a permanently mounted absence of voltage tester.
    • Use of noncontact capacitive test instruments permitted for testing each phase conductor on electrical systems over 1000 volts.
    • Grounding of circuit conductors and parts before touching them in the presence of induced voltages or stored electrical energy.
    • Placement and capacity requirements for temporary protective grounding equipment to prevent exposure to electric shock hazards.
