3. System Overview 1 Step Over KEE WALK ® Step Over is a complete range of safety Step Overs designed specifically to provide permanent safe access for areas on roofs or in warehouses where regular access for maintenance and inspection is required. A KEE WALK ® Step Over system is designed to provide a safe means of access up and over obstructions present in a designated walkway as part of a safe roof access system or as a standalone item used internally (I.e warehousing) when access is required. Can be combined with KEE WALK, or as a stand alone item when access or egress is required over an obstruction. The Step Over system provides both a demarcation route for flat roofs which are not accessible to the public, where access is still required for the purpose of carrying out repairs and maintenance. They can also be used within a warehousing environment or internal application where access up and over plant or equipment is required in order to provide safe passage from point to point. APPLICATION KEE WALK ® Step Over has been designed to be fully adjustable and can accommodate heights from 600mm up to 1400mm. DURABILITY KEE WALK ® Step Over is available in a range of high quality finishes. The components are supplied with a galvanised finish carried out to BS EN ISO 1461 and ASTM A53: Hot Dip Galvanised Coatings Specification and Testing Methods, giving an average coating of between 65-85 microns. All cast clamps have Threadkoat applied to all tapped holes. All grub screws are carbon steel and have Kee Koat protection applied to ensure minimal maintenance. COMPONENT BASED SYSTEMS All products consist of high quality tubing that seamlesly complements our existing safety portfolio. KEE WALK ® Step Over mounts easily to all variants of the KEE WALK Walkway & KEEGUARD systems as well as Safe Access Solutions such as Mobile Access Platforms & Static Access Platforms. VERSATILE SYSTEMS The KEE WALK ® Step Over range has been specially designed with different heights and foot styles to accommodate all levels and roof types. The flexibility of the KEE KLAMP design allows the systems to be used on plant congested or complex detailed roofs. The product range has been extended to suit specific requirements and includes the standard design and bespoke solutions.

13. Assembling the Step Over 11 STEP 6 - Assemble the remaining guardrails and toe board Take the forward assembled uprights (Part B) and insert into the 29-7 fitting present on the stair assembly and loosely tighten the fittings. Starting on one side, insert the two inclined hand rails (Part C) into the 326-7 fittings present on the rear upright, and manoeuvring the front upright forward insert both rails in the 29-7 and the 55-7 fittings, move the upright back to its upright position and loosely tighten. Using a spirit level, ensure the forward upright is plumb and level in the X and Y plane, once level, tighten all grub screws to 39Nm. Repeat for other side of staircase, and then repeat the entire procedure for the other staircase. STEP 7 – Fitting toe board Locate toe board (Part E) inboard of bridge platform and pick the TBFP1 fixing packs and TB3-7 toe-board fixing clamps. Insert the M12 bolts into the extruded channel, and locate 1 bolt either side of each upright as shown in the illustration. Locate the TB3 clip onto the bolts, fits the nuts and washers. Level the toe board and tighten the fixings to 25Nm. STEP 6 STEP 7

11. Assembling the Step Over 9 STEP 3 - Assemble bridge module and guardrail onto rear leg uprights Take the bridge platform subassembly (Part F) framework and insert into the 326 fitting present on one side of the rear uprights, followed by the guardrails (Part B) into the fittings further up the upright. Bring the opposite outer leg assembly to meet the platform, and locate tubes from bridge module subframe into the slope fittings present on the uprights. Add the Kee Walk bridge tread assembly to the substrate, ensuring it is centred left/right and front/ back and fix into place using the 105-7 fittings to the underside and securing in place with self- drilling screw. Repeating all sub sets of step 1 to build other side of platform uprights Inserting bridge subframe tubes into uprights at obstruction Inserting bridge subframe tubes into uprights at obstruction and securing walkway STEP 2 - Repeat Step 1 for other side of stair case Repeating of Step 1 enables the other side of the uprights to be built, which in turn allows the next phase of the build to commence.

12. Assembling the Step Over 10 STEP 4 - Staircase assembly Take the stair tread assembly module (Part H) to the area in which it is to be installed, and collect the 440 weights, cross tubes and relevant fittings (Part A). Insert the lower weight cross tube into the lower 10-7 fittings sliding from left to right; space the tube such that an equal overhang exists both sides and tighten grub screws on 10-7’s to 39Nm. Locate cross brace tube into C50-77 fitting and tighten. Take the pre-assembled stair module and move towards assembled bridge platform in previous steps. STEP 5 - Staircase assembly Locate upper tube from staircase and brace tube in the correct orientation to meet the corresponding tube sockets in the lower 29-7 and upper 326-7 fitting. Starting with the upper tube, manoeuvre the lower tube down towards the stair assembly and lower the staircase so that the upper tube can be inserted Into the 326-7 fitting. Before fitting fully, locate the lower tube into 29-7 fitting. Push both tubes on both sides home, ensuring staircase is square. Lightly tighten grub screws to locate stair assembly into place. Insert the 74-7 fitting into the weights and slide the weights onto the end of the tube ensuring that they are fully inserted. Double check for location, once happy tighten all grub screws to 39Nm. Repeat the procedure for the other staircase. STEP 4 STEP 5

4. System Overview 2 TESTING & CERTIFICATION Tested in accordance with the following (See Specification Section for full details) :- EN ISO 14122: 2016 Part 3 KEE WALK ® Step Over systems do not require physical fixing to the building’s structure. The complete system’s design, manufacture, testing and installation have been internally assessed and designed in accordance with EN 14122-3 European Standards. OFFICIAL DOCUMENTATION All Systems comply with the following: - Work at Height Regulations. - HSG-33, Health & Safety in Roof work - HSE INDG 284- Working on Flat Roofs - BS EN 516: 2006 AESTHETICS The smooth lines of the standard galvanised finish can be further enhanced by the application of powder coating to EN 13438. MATERIALS Steel tubing to EN 10255. 42.4mm diameter tube x 3.2mm wall thickness. All steel components galvanised to BS EN ISO 1461. All fixings are hot dipped galvanised to BS EN ISO 1461.

Products are available from Kee Safety directly or one of its licensed distributors.

14. Assembling the Step Over 12 STEP 8 - Levelling and finalising of treads With the platform now fully assembled, check the tread rise (distance in height between treads), going (where the tread sits in plan), and angle. Starting at the bottom tread, measure the rise between the treads ensuring that there is no more than 5% difference between any two tread heights*. Looking from above, there should be a minimum of 10mm overlap on the treads*. Starting at the top tread, and using a spirit level, ensure that all treads are level left/right and forwards/backwards. If an adjustment needs To be made in the fore/aft level simply slacken the grub screws on the 45-76 and 10-76 on both sides, adjust tread to correct, level angle and re- tighten. If adjustment needs to be made to accommodate the 10mm overlap between treads, simply undo the 13mm nuts holding the tread extrusion to the 199-6 fitting and adjust, ensuring that they are re-tightened on completion. (* = The Stair rail and tread assemblies are pre-assembled at Kee Safety so no major adjustments should be required) STEP 9 - Check and recheck all grub screws and finalise assembly Once all treads are level, the platform is fully assembled, and the toe board is present ALL grub screws are to be torqued to 39Nm Starting at the lower left staircase, working from the lowest point, systematically tighten all grub screws with a calibrated torque wrench and indelibly mark the grub screws with a paint marker once at torque. This performs two functions, it lets the installer know once a grub screws has been tightened, but also on annual inspection allows the inspector to see if a grub screw has come lose and needs attention. The same principle is applied to all other fixings, using 18Nm for all 13mm headed fixings, 25Nm on toe board M12 fixings and Tek Screws to be tightened until a compressing of the foam backed washer is observed. It is IMPERATIVE that ALL grub screws and fixings are checked on the ENTIRE assembly and torqued up to the correct torque value and marked!! STEP 8 STEP 9

19. Kee Walk Step Over System Recertification 17 Periodic inspections by a competent person are recommended by the manufacturer. In UK/Europe these are required under Regulation 5 of the Workplace (Health, Safety & Welfare) Regulations, the Work at Height Regulations and BS EN 365. The frequency will depend upon the environment, location and usage but should be at least every 12 months. Walk and visually inspect the complete installed system in relation to the client's general needs. Establish if any modifications and/or additional products are required to reflect any refurbishment requirements or additional plant & equipment which have been installed and require access. Check installation configuration is complete as per the original installation drawing/plan. Ensure the system has not been modified or tampered with by un-authorised persons. Check all base feet are in contact with the roof. Check all counter weights (where present on original drawing) are in place as per the original drawing. This is essential for longevity of the roof. Check all grub screws are in place and correctly torqued. Check the general height and level of the system including the leg centres and platform overall configuration. (This only tends to be an issue if the system has been tampered with between inspections). Any galvanised components showing signs of corrosion should be wire brushed thoroughly and galvanised spray/paint applied as appropriate. If rusted significantly, take digital photographs and include these in the inspection report. Where toe boards are fitted check the brackets that support the toe board are in place and sufficiently torqued. Where applicable check fixings to walls/structures including cat ladder clamps are in place and sufficiently torqued. 7. KEE WALK STEP OVER SYSTEM RECERTIFICATION

10. Assembling the Step Over 8 STEP 1 Assembling back leg upright with weights and cross rail Take both back upright assemblies (Part G) to the position of the obstacle, along with the weighted foot assemblies (Part A). Starting with the left-hand side back upright assembly, up end the upright such that it is orientated with the 10-7 fitting at the bottom. Pick up the weight cross rail, and feed through into the lower fitting of the upright, and slide the right-hand side towards the left. Insert the cross rail at mid-point to connect both uprights together. Insert the 74-7 fittings into the 440-7 weights and add the weights to either end of the tube, ensuring the weights are inserted fully. Tighten the 74-7 grub screws to 39Nm. Manoeuvre the assembled rear upright into position at the point of install. Tighten all grub screws to the required 39Nm torque setting. 5.
