In UK/Europe these are required under Regulation 5 of the W orkplace (Health, Safety & Welfare) Regulations, the Work at Height Regulations and BS EN 365 & BS 13700. The frequency will depend upon the en vironment, location and usage but should be at least every 12 months. • W alk and visually inspect the complete installed system in relation to the general client’s needs. Establish if any modifications and/or additional p roducts are required to reflect any refurbishment requirements or additional plant & equipment which have been installed and require access. • Check installation configuration is com plete as per the original installation drawing/plan. • Ensure the syst em has not been modified or tampered with by unauthorised persons. • Check all base f eet are in contact with the roof membrane. • Check all count er weights are in place as per the original drawing. This is essential for wind loading calculations. • Check all grub scre ws are in place, greased and sufficiently torque. • Check that the general height and le vel of the system including the leg centres. (This only t ends to be an issue if the system has been tampered with between inspections). • An y galvanised components showing signs of corrosion should be wire brushed thoroughly and galvanised spray/paint applied as appropriate. If rust ed significantly, take digital photographs and include these in the inspection report. • Where t oe-boards are fitted check the brackets that support the toe-board are in place, greased and sufficiently torqued. • Where applicable, check fixings t o walls/structures including cat ladder clamps are in place, greased and sufficiently torqued. • Check syst em plaque position & mark up to reflect date of the next required inspection. Establish if additional plaques are required due to an y refurbishment works. Guardrail Systems Recertification

3. 3 SAFETY GUARDRAIL SYSTEMS The Company’s guardrail system KEEGUARD has been designed specifically to provide permanent edge protection for areas where regular access for maintenance and inspection is required. UNIQUE SYSTEMS Each system’s unique design provides permanent edge protection without the need to mechanically fix the system through the roofing membrane or building’s structure. Their simple cantilever principle provides unrivalled strength, stability and safety and overcomes the problems associated with traditional systems such as having to drill and puncture the roof membrane which can lead to potential penetrative water damage and noise disturbance during installa - tion. Similarly, high levels of insulation included within warm deck and inverted flat roof designs often mean it is virtually impos - sible to fix through, as with traditional systems, without causing cold bridging. This may then cause interstitial condensation to form within the flat roof construction, causing the roof to deteriorate and eventually require replacement. When it is not appropriate to use counter balanced systems, such as modern industrial cladded pitched roofs, KeeGuard Topfix may be an alternative to traditionally fixed systems. DURABLE SYSTEMS The Company’s guardrail connections 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 products are also available in aluminium. All cast clamps have Threadkoat applied to all tapped holes. All grub screws are carbon steel and have Keekoat protection applied to ensure minimal maintenance. COMPONENT BASED SYSTEMS All systems consist of galvanised/aluminium tubing joined together using the KEE KLAMP method of connection. KEEGUARD, raked, radiused and folding systems’ base feet con - nect to the 100% recycled PVC counter weight, giving the system its strength & stability. VERSATILE SYSTEMS All systems have been specially designed to fit any shape and size of flat and pitched roofs, even circular designs. The systems can also cope with changes in levels, roof falls and difficult details such as ductwork passing over the roof edge and cable trays/plant mounted at the roof edge. The lexibility of the counter weight & 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 with vertical legs, raked and radiused systems, as well as a folding version for areas where a more discreet form of protection is required. KeeGuard Topfix has also been added to the range to provide collective protection solutions for industrial cladded pitched roofs. KeeGuard System Overview

4. 4 MEMBRANE PROTECTION SYSTEMS Each system is installed with rubber matting bonded to the underside of metal components which come into contact with the roof membrane. In some cases the counter weight and base foot have sacrificial pads placed between the edge protection components and the roof membrane. This protects the roof membrane from damage via heat transfer or direct contact with components. On warm deck roof construction specifications pedestrian tiles are recommended to be placed where base feet and counter weights are in contact with the roof membrane. Where KeeGuard Topfix is installed a butyl strip is used where the Base Plates are fixed, via rivets, to the roof cladding. TESTING & CERTIFICATION Tested in accordance with:- EN 13374 Class A. BS 13700, Permanent counterweighted guardrail systems – Specification EN ISO 14122 Part 3. NF E85-003 EN 1991-1-4 BS 6399 : Part 2 Code of Practice for Wind Load. WIND CALCULATED Wind loading is the most likely regular and demanding force a free standing roof guardrail will encounter during its lifetime. The Company has developed a computerised programme to calculate the design to ensure compliance with the relevant wind loadings relating to the topography, height and location of the project throughout the World. OFFICIAL DOCUMENTATION All Systems comply with the following:- Work at Height Regulations. HSG 33 “Health & Safety in Roof work” HSE Construction Sheet No. 21 “Working on flat roofs protection against falls.” European Union Directives together with requirements of CDM Regulations. AESTHETICS The smooth lines of the standard galvanised/aluminium finish can be further enhanced by the application of powder coating to BS 6497 Specification for Powder Organic Coatings, EU Codes with bespoke colour produced to special order. Counter weights are available in black or other colours at an additional cost. Where a more discreet form of protection is required, raked and radiused systems, as well as a folding version are welcomed by Planning Officers due to their improved aesthetics. SYSTEMS DISTRIBUTORS All systems are available as a supply and installation service or component supply only. Products are available from The Company directly or one of its licensed distributors. INDUSTRIAL CLADDED ROOFS The Company has developed a new collective roof edge protection system, KeeGuard Topfix specifically for metal profile and stand - ing seam roofs up to 45°. Pitched cladded roofs have traditionally been protected using personal fall protection systems which are lower in the hierarchy of controls. KeeGuard System Overview
