76 SAFETY & SECURITY
With any type of fencing, the most vulnerable areas are the fixings and panel connectors. Screws, bolts and rivets should be tamper-proof to prevent them from coming loose and compromising security, or being removed manually to gain access. Similarly, panel-to-post connectors should be concealed to ensure that whole panels cannot be removed from the posts. All fixings should be galvanised or stainless steel for added protection against corrosion. With all of us trying to make more responsible, sustainable choices, it's important to choose fencing that has a traceable supply chain, and offers a long guarantee. A 25 year guarantee demonstrates the manufacturer's confidence in its products, and their dedication to providing reliable, long-lasting products that reduce their carbon footprint. Where visible deterrents are necessary, or where there is a risk of climbing – e.g. buildings, trees, or lamp posts could be used to gain purchase – security toppings can be added to the fence. Barbed wire is a cost- efficient option with a suitably menacing appearance, while rotating spikes ensure that even the most prepared would find it impossible to gain access by climbing.
Warning signs must be visible where fence toppings are in place, and these act as an additional deterrent by themselves. Gates should always be considered at the same time as fencing, and should match the type of fencing to guarantee consistency of security, as well as providing a polished appearance. There are many types of gates available, from swing gates, to tracked or cantilever sliding gates, or bi-folding gates that offer rapid access. Access control devices should be chosen to suit the type of gate and security level of the site, such as card readers, key fobs, digital pads, and key locks. To increase safety, separate gates should be installed for vehicles and pedestrians. This will also increase security – having smaller entrances for pedestrians reduces the need to open vehicular gates to allow them access, and avoids leaving large gaps in the perimeter. When specifying automated gates, it is essential that they are CE marked, and all Door Hardware Federation safety standards and guidelines should be strictly applied to ensure full safety compliance.
