III.   GROUND-FAULT PROGRAM

       ((THERE ARE TWO DIFFERENT PROGRAMS THE FACILITY MAY CHOOSE TO
       IMPLEMENT, THE GROUND-FAULT CIRCUIT INTERRUPTER (GFCI) PROGRAM,
       OR THE ASSURED EQUIPMENT GROUNDING CONDUCTOR PROGRAM.
       COMPLETE THE FILL IN THE BLANK FOR THAT PROGRAM WHICH WILL BE
       USED AT YOUR FACILITY. THE OTHER PROGRAM SHOULD THEN BE
       DELETED FROM YOUR FACILITY SPECIFIC WRITTEN PROGRAM. YOU MAY
       ALSO CHOOSE TO USE BOTH PROGRAMS.))

       A.   The Ground-Fault Circuit Interrupter (GFCI) Program

            The GFCI Program will be used at the ENTER FACILITY NAME facility, and
            requires that a GFCI is located between the power source and the tool and
            for all outlets subjected to potential splash from liquids (use 3-foot rule).

            1.    Equipment

                  There are a number of different types of GFCIs that can be used. The
                  ENTER FACILITY NAME facility will use:

            ((DELETE THOSE YOU WILL NOT BE USING. ADD ANY TYPE THAT YOU
            DO USE, IF NOT LISTED HERE.))

                  a.     Purchase extension cords that come equipped with GFCIs.

                  b.     Purchase GFCI outlets and electrical boxes and have a certified
                         electrician put them together and attach them to an extension
                         cord. Employees can then plug their extension cord into the
                         power source and plug the tool being used into the GFCI.

            2.    Training

                  Supervision or the Electrical Safety Program SPA will instruct
                  employees on the GFCI Program in the work area. The training will
                  cover the following:

                  a.     The definition of a GFCI:

                         The GFCI is a fast-acting circuit breaker which senses small
                         imbalances in the circuit caused by current leakage to ground,
                         and in a fraction of a second, shuts off the electricity. GFCIs
                         monitor the difference in current flowing into the "hot" and out to
                         the grounded neutral conductors. The difference in current will
                         flow back through any available path, such as the equipment
                         grounding conductor, or through a person holding the tool if the
                         person is in contact with a grounded object, (standing on the
                         ground).
b.   Why GFCIs are needed:

     Extension cords tend to get twisted, punctured, etc. This may
     result in a conductor becoming exposed, allowing for the
     potential hazards of electrical shock, burns, or fire. The GFCI
     will sense the imbalance and immediately shut off the electricity
     to that tool, eliminating the potential hazard to the employee.

     GFCIs also provide protection against fire, overheating, and
     destruction of insulation on wiring.

c.   The proper use, limitations, and testing of the GFCI:

     1.    When an employee is using temporary wiring such as
           extension cords in the work area, they must have a GFCI
           between the power source and the tool.

     2.    The Office of Electrical, Electronic, and Mechanical
           Engineering Safety Standards does not recommend the
           use of GFCI testers as a means of determining
           compliance with OSHA regulations (i.e.,
           §1926.404(b)(1)(ii)), as such testers may not produce
           accurate results. Ground-fault circuit interrupters
           incorporate a testing circuit that can be used to
           determine whether or not the device itself will function as
           intended. No further tests are necessary.

           Any GFCI tester that puts a resistive load between the
           ungrounded circuit conductor and the equipment
           grounding conductor1 to measure the current at which
           the device trips is subject to errors due to voltage
           fluctuations. If the circuit voltage is 100 volts, the tester
           could indicate that a GFCI tripped at 7.2 mA when it
           would actually have tripped at 6.0 mA.

           Testers like the Greenlee model 5708,(2), cannot
           produce a reliable indication of the trip level of a GFCI.
           This device sends a 200-millisecond pulse through the
           grounding conductor at various current levels. A GFCI
           may not trip at minimum current levels (that is, 6-20mA)
           in such a short period of time. (For example, UL
           Standard 943 allows trip times of up to 1.5 seconds at
           15mA.) This tester provides a 4-second interval between
           pulses and cannot be adjusted to provide a longer pulse
           or a shorter interval.
               Additionally, an employer cannot reasonably be expected
               to know at what level his or her GFCIs trip. A reasonable
               person would only expect the employer to check them
               periodically using their built-in test mechanisms.

         3.    Periodically (quarterly), the GFCI will be tested using the
               test button on a GFCI in combination with an attached
               load plugged into the circuit to be tested rather than a
               GFCI tester. A plug-in ground continuity tester would
               suffice as an attached load. If the lights on the continuity
               tester go out when the test button is pressed, the GFCI
               can be assumed to be operating correctly. If the lights
               stay on or if the test mechanism fails to operate, the
               GFCI is faulty, and needs to be replaced.

         4.    The GFCI will not protect the employee from line-to-line
               contact hazards, (such as a person holding two "hot"
               wires or a "hot" and a neutral wire in each hand).

    d.   Why GFCIs are required to be used on temporary wiring:

         Fixed wiring is secured and protected (conduit), therefore, fixed
         wire is not as exposed to the wear and tear of temporary wiring.

    e.   Employees must use a GFCI on every job where they are using
         temporary wiring. If they are not going to use a GFCI, they will
         have to test and tag the cord or tool in accordance with the
         Assured Equipment Grounding Conductor Program.

NOTE:    Employees must sign off on the Ground-Fault Training Log,
         (see Appendix 1.0), which the Ground-Fault Program
         Coordinator will collect and maintain.
((SECOND GROUND FAULT PROGRAM BEGINS HERE))
     B.   The Assured Equipment Grounding Conductor Program

          The Assured Equipment Grounding Conductor Program will require
          employees to physically test all cord sets and receptacles that are not part of
          the permanent wiring. A written copy of this program will be maintained at
          the jobsite. Every cord set and receptacle will be tested on a quarterly basis.
          This testing will be identified by tagging the male end of the plug with a
          colored piece of tape (a different color tape will be used for each calendar
          quarter). Every employee affected by this program will have a tester.

          1.    Equipment

                All employees are to have a tester. The receptacle tester to be used
                will check correct wiring for 15 or 20 amp, 120V AC single-phase 3-
                wire receptacles, with color lamp combinations that indicate correct
                wiring.

          2.    Testing

                a.     All cord sets and receptacles must be visually inspected prior to
                       use. This will help employees identify any visual problems with
                       their equipment.

                b.     All equipment grounding conductors will be tested on a quarterly
                       basis. This will identify any internal problems that cannot be
                       visually identified. Testing will also be required for the following:

                       1.     When equipment is initially brought onto the jobsite
                              (before the first use).

                       2.     When a daily visual inspection identifies a problem.

                       3.     When equipment is brought back into service after being
                              repaired.

                c.     All testing required in Section B.2.b. must be documented using
                       Appendix 2.0. This documentation must be kept at the facility
                       or jobsite for the current year. (If an OSHA compliance officer
                       inspects the jobsite they will want to see this documentation.)
3.   Identification of Testing

     To show that the required testing is being conducted, the tagging
     system Johnson Controls uses is to tape the end of the male plug with
     a colored piece of tape. Any type of electrical tape can be used in
     these four colors:

            Quarter #1 January-March           Yellow Tape
            Quarter #2 April-June              Red Tape
            Quarter #3 July-September          White Tape
            Quarter #4 October-December        Blue Tape

4.   Training

     The Assured Equipment Grounding Conductor Program training will be
     performed in the work area, and include the following:

     a.     Why the Assured Equipment Grounding Conductor Program is
            needed:

            On construction or maintenance sites extension cords tend to
            get twisted, punctured, etc. This may result in a conductor
            becoming exposed which will allow for the potential hazards of
            electrical shock, burns, or fire. Daily visual inspections will
            identify any potential hazards and give employees an
            opportunity to correct them. Quarterly testing will identify any
            internal problems with the cord sets or receptacles.

     b.     Conducting the Testing

            The supervisor will show employees how to test cord sets and
            receptacles. Employees must be shown how to use the
            receptacle tester and the lights that indicate the wiring is good,
            and the lights that indicate incorrect wiring.

     c.     Testing Requirements

            Employees must be instructed when to test their cord sets and
            receptacles, and the following must be explained:

            1.     Cord sets and receptacles must be tested when
                   temporary wiring is used.

            2.     Testing should be conducted on a quarterly basis, when
                   equipment is initially brought on the jobsite, when the
                   daily visual inspection identifies a problem, and when the
                   equipment is returned following a repair.
        3.   In order to identify that a cord set or receptacle has been
             tested, a colored piece of tape must be placed on the
             male end of the plug.

NOTE:   Employees must sign off on the Ground-Fault Training Log
        (see Appendix 2.0), which the ground-fault administrator
        should collect and maintain.
