6 Safety Information Safety Information Vehicular gate systems provide convenience and security. Gate systems are comprised of many component parts. The gate operator is only one component. Each gate system is specifically designed for an individual application. Gate operating system designers, installers and users must take into account the possible hazards associated with each individual application. Improperly designed, installed or maintained systems can create risks for the user as well as the bystander. The design and installation of gate systems must reduce public exposure to potential hazards. A gate operator can create high levels of force, in its function as a component part of a gate system. Therefore, safety features must be incorporated into every design. Specific safety features include: Gate Edges Enclosed Track Vertical Posts Guards for exposed rollers Photo-electric Sensors Instructional and Precautionary Signage Screen Mesh Important instructions follow. These instructions are intended to highlight certain safety related issues. These instructions are not intended to be comprehensive. Because each application is unique, it is the responsibility of the purchaser, designer, installer and end user to ensure that the total gate system is safe for its intended use. Safety Instructions Selected Instructions are highlighted with a precautionary symbol (see left margin). Failure to follow these selected instructions can result in serious injury or death. STEP 1: BEFORE INSTALLATION 1 Confirm gate operator model is specified by Installation and Maintenance Manual for application type, gate size and frequency of use. 2 Confirm ALL appropriate safety features, such as gate edges, photo-electric sensors, vertical posts and enclosed tracks, are specified. 3 Confirm the gate system design reduces pinch points and protects against entrapment. 4 Confirm gate system design has pedestrian access separate from vehicular entrance. 5 Confirm gate system design reduces traffic backup. 6 Confirm warning signage is included in design. 7 Confirm gate moves freely before installation of operator. 8 Repair or service worn or damaged gate hardware before installation of operator. 9 To avoid installation hazards, review the gate system operation and installation procedures, such as manual disconnect mechanism procedure. 10 Confirm control design prohibits unauthorized use.
