I'm sure someone will provide a reference document or standard. We took a common sense apporach and adotping the following: - Suitable all-weather padlocks provided to site - Suitable number of back up padlocks stored securely in managers office - Process agreed and trained out to all management for de-icing frozen padlocks - Policy that gates always padlock in either the closed (down) position or open (up) posirtion. Gates to never not be padlocked - Check before store opens (gates up and padlocked up) and after store closes (gates down and padlocked down) - Audits by territory / area managers when they go to their sites of car park gates - Policy that if for any reasons gates cannot be secured in the open position the car park is not opened to the public The above provided a suitable level of assurance to us (but assumes your gates have a manual lock off - I beleiev this is the most common type in any case).

One of the biggest problems re such items is the quality side of the on-site installation as they are generally designed and fabricated by professionals but installed by average builders One fatality I investigated drew attention to the fact that some site welding had taken place by the installer - a builder - who did not know how to weld! And they also used low tensile bolts instead of high tensile bolts even though HT were specified Additionally sometimes people use such areas for camping and similar so mistreat the gates to get into the areas so security can be an issue - Just some observations
