33.             GROUNDING CONDUCTOR / ASSURED GROUNDING

                This procedure provides the standard method for implementing and maintaining an OSHA
                Assured Equipment Grounding Conductor (AEGC) program.


                A.              SCOPE

                                This procedure outlines specific electrical inspection procedures and the frequency of
                                inspection for electrical tools and electrical equipment.
                                Note!!! This procedure does not supersede the requirements to visually inspect all
                                hand tools before and after each use.


                B.              RESPONSIBILITIES

                                Contractor shall maintain a record of all electrical equipment in Contractor’s Tool Room
                                on the site.
                                All electrical tools arriving onsite must be inspected per this procedure prior to use on
                                this site. The tools and equipment must be re-inspected periodically as outlined below.
                                Inspection records shall be made available to Owner upon request.
                                Contractors shall inspect construction electrical tools and electrical equipment as outlined
                                in this procedure and shall keep records of all inspections and repairs performed
                                throughout the duration of the project.
                                Only qualified electricians shall repair the electrical components of construction electrical
                                tools and electrical equipment.

                                Only competent and qualified electricians are allowed to perform the monthly inspections
                                and affix the monthly color code. Contractor shall appoint and certify personnel specific
                                for this task.


                C.              PROCEDURES

                                Electrical tools or electrical equipment are not to be issued for use until inspected.
                                Electrical tools and electrical equipment determined by inspection to be in need of repair
                                are to be tagged "defective" until repaired. Following repair, the tool or equipment must
                                be inspected before it can be used in the field. Under no circumstances may tools or
                                equipment in need of inspection or repair remain in service.
                                Each craft shall ensure that electrical tools and equipment it has, or is using, bear the
                                current inspection tape or tie wraps. Before using any electrical tools and equipment, the
                                crafts person shall visually inspect such equipment for defects. If any defect is found or
                                the equipment does not bear a current inspection sticker, the equipment shall be returned
                                for inspection.
                                "Defective" electrical tools and equipment are to be tagged and removed from service
                                until repaired and inspected.

                                The craft person using the tools and equipment shall ensure that the markings remain on
                                between inspections. The color codes and their corresponding scheduled inspection dates
                                are:


                              Yellow               Blue                  Orange                 Green          Red              White

                                shall be inspected quarterly monthly an approved tester in conjunction with a visual
                                inspection. For example:
                                       Model B-2500 tester made by Pow-R-Safe division of Multi-Amp Corporation,

                                Voltage testers or measurement devices shall be inspected monthly. The electrical test for
                                inspecting voltage testers or measurement devices should include test live AC and DC
                                voltage. Personal protective equipment shall be worn while testing.

                                As a minimum, the visual inspection shall include:

                                       Checking the leads for signs of wear, poor connections at probes, etc.
                                       Checking the housing and the readout window for cracks, loose screws, etc.

                                 Check all Ground Fault Circuit Interrupters (GFCI) during the monthly inspections.

                                 Note: All electrical tools and equipment that are not Double-Insulated must be equipped
                                 with a Ground Fault Circuit Interrupter (GFCI).

NOTE:           ELECTRICAL TOOLS, EXTENSION CORDS, ETC. ARE NOT TO BE USED WITHOUT
                       THE PROPER COLOR CODE AND INSPECTION TAG.


                F.              DOUBLE-INSULATED TOOLS
                                Double-insulated, portable hand tools may be used provided they bear the Underwriters
                                Laboratories' "double-insulated" label and are of heavy-duty construction.
                                Double-insulated tools shall be inspected quarterly. The inspection shall include the
                                visual inspection as already outlined as well as the following electrical tests:
                                A Multi-Amp test, accomplished by connecting two leads on any clean metal points on
                                the equipment housing - one lead into the black receptacle on the test set (simulating the
                                third wire), the other lead into the white receptacle (which is the same as the grounding
                                cradle on the tester). The presence of leakage current (caused by carbon or moisture
                                paths, or insulation breakdown) is indicated as a "power ground." Also during this same
                                test, a line-to-line short circuit anywhere in the equipment, line cord, or switch will be
                                indicated as a "short circuit."
                                After completing the Multi-Amp tests, verify that the GFI works properly using a
                                Hubbell GFT. Remove the Hubbell GFT-2F and plug in the double-insulated tool. If the
                                GFI trips with the tool running, the tool is defective and shall be repaired or replaced.


                G.              MONTHLY INSPECTIONS - SHOPS

                                Permanently wired shop equipment shall be inspected monthly. Inspection should include
                                the following items:

                                       Checking for proper overload protection.
                                       Checking mechanical operations of the switch.
                                       Checking continuity of ground.
                                       Checking limit switches.
                                       Checking interlocks.
                                       Checking for frayed cords.
                                       Checking for broken plugs and outlets/sockets.
                                       Checking flexible conduit and connectors.
                                       Office equipment shall also be inspected monthly.

                                        As use of certain test instruments can damage electronic components in computers
                                        and similar office equipment, visual inspection is all that is necessary for the type of
                                        office equipment.
