48 Security Dealer & Integrator / www.SecurityInfoWatch.com November 2018 Perimeter Security The requirements to ensure that an automated gate system is installed safely are clearly outlined in both standards, and both ASTM F2200 and UL 325 requirements are also included in the International Building Code, International Fire Code and International Residential Code. For installation training and assistance, the American Fence Association (AFA) offers comprehensive training classes on automated gate design and installation; and the Door and Access Systems Manufacturers Association (DASMA) provides overall guidance for gate operator safety from the perspective of the public interaction with automated gates. Additionally, DASMA references UL 325 and ASTM F2200 to identify typical entrapment zones in both swing and slide gate applications. With all of the noted standards and agencies, how can there still be so many injuries and fatalities resulting from automated gate installations that do not meet the standards? The short answer is that UL 325 is a voluntary standard – with the exception being the state of Nevada, where UL 325 compliance is required by law. While UL 325 may be a voluntary standard, installers put the public and their business at significant risk by not following its requirements. Accountability for an unsafe gate installation is typically raised after a gate-related accident has occurred. Those held responsible in accident litigation cases typically include the gate installer, the company the gate installer works for, the gate operator manufacturer, the property owner, the property management company as well as anyone who has worked on the gate system at any point in time. The frequency and magnitude of these cases are significant, with very real consequences associated with not ensuring a gate installation is done safely and in full compliance with ASTM F2200 and UL 325 standards. If you are in the gate operator business, you have an obligation to understand the requirements of the standards to help protect people from potential dangers of an automated gate. By holding yourself accountable to the gate safety standards, you reduce risk to the public and potential liability, while gaining a strong safety reputation for your business. Inside the Standards The simplest way to understand the intent of UL 325 is that if a condition exists where a person can be caught or held in a position that increases the risk of injury, then that zone is an “entrapment zone.” As recently as Aug. 1, 2018, UL 325 was updated to further drive gate system safety, requiring gate operators (both swing and slide) have a minimum of two monitored safety entrapment protection means in both the open and close directions. Most manufacturers incorporate an inherent reversing system into a gate operator, which is one means of entrapment protection in both the open and close direction; however, additional entrapment protection devices, such as a monitored safety edge or monitored photo eyes, are now required for safe operation. If the gate operator detects one or both of these devices are not connected or not working, the gate operator will not function. A gate safety checklist is a great way to inspect swing and slide gate operators to ensure they meet UL 325 and ASTM F2200 standards. As part of LiftMaster’s ongoing gate safety awareness campaign, it has created the following gate safety checklist: • Check the operator label to see if the gate operator is approved to current UL 325 standards. • Attach proper gate warning signs to both sides of the gate area. • Be sure all entrapment zones in both the open and close direction are protected by two safety devices. • Is the gate constructed to the ASTM F220 Standard? Construction should include: Smooth bottom edges with no protrusions that exceed one-half inch beyond base of gate; all access controls at least six feet from the gate; a separate pedestrian gate that is out of reach of the moving gate; the gate does not move on its own if it is disconnected from its operator; and the gate is prevented from falling over if disconnected from supporting hardware. • For slide gates, all openings of the gate and adjacent fence must be small enough to not allow a 2.25-inch sphere from passing through; gaps between the gate and fence posts must be less than 2.25 inches; and positive stops are required in both the opening and closing positions.
