3 STRAPPING TEAM PRE-START CHECKS As the COSS, confirm that you have received and verified the SSOW Pack a minimum of one shift before work starts (pack to include strap layout diagram). Check that you have the required equipment and PPE to undertake your role. Check that all the equipment is in good condition. Before going to the strapping location you must receive a face to face briefing from the Engineering Supervisor (ES).

4 5 Check that you know where the strapping access point is and where the strapping points are relative to the access point. If not sure ask the ES to show you. DO NOT START WORK WITHOUT THE ABOVE ITEMS BEING IN PLACE PRE-START CHECKS

5 BEFORE PLACING STRAPS 1 2 Check that the SSOW covers from the access point to the strapping location. Use the following to confirm that you are in the correct location: a. Access point signage b. SSOW pack (principal source of information) c. Sectional Appendix and Track diagrams d. Mileage posts and chainage markers e. Use a smartphone app (such as Omnicom) but only as a check (remember GPS is not always accurate).

6 Before going on or near the line Confirm you have been briefed. 1 STEP

7 STEP 2 Check the condition of your PPE and equipment.

8 Check you are wearing the correct PPE (gauntlets, safety goggles, safety helmet, safety boots and flame retardant overalls). 3 STEP

9 STEP 4 Using a wire brush, clean the underside of the two running rails where the clamps are to be fixed.

10 Fix strap to running rail FURTHEST from conductor rail and tighten securely. 5 STEP

11 6 STEP Fix strap to running rail CLOSEST to conductor rail and tighten securely.

12 Before testing the conductor rail check the Live Line Tester is working correctly using the Proving Unit. 7 STEP

13 2nd Test that the 8 1st conductor rail is NOT live using the Live Line Tester. (Immediately check the Live Line Tester on the Proving Unit again afterwards). STEP

14 Insert the Short Circuiting Bar, shout a warning and swiftly push down to apply (stand with your back to the conductor rail and look away). 9 STEP

15 STEP 10 With the Short Circuiting Bar still in position, wire brush the underside of the conductor rail.

16 With the Short Circuiting Bar still in position, push strap under the running rail and conductor rail and secure tightly to the conductor rail. 11 STEP

17 STEP 12 Check that all clamps are secured tightly and that the strap is not creating a trip hazard. Remove the Short Circuiting Bar, pick up the equipment and exit the site using SSOW.
