When you fall into the one of the categories that make you a responsible person, you must ensure that these devises are safe, and that they are inspected on a regular basis. Ideally you document that inspection on a daily walk sheet. Upon inspection you want to ensure that the device is effective in its functionality. The gate should be installed according to the manufacturer's guidelines.
Finally, there are four types of people that will be interfacing with your powered gates. Firstly, the competent person that is installing and repairing the gates. This person will most likely create the least traffic through the gate. Secondly, the owner, this person may or may not use the gate every day, but is legally obligated to be the most knowledgeable in its operation. The third individual will operate the gate most often, they are the employee or resident. They will rely on its safe operation daily. They will need the owner to be proactive with preparing the gate to operate flawlessly. Lastly is the curiosity seeker. This may be an animal, or an uneducated person. They unknowingly require the safety devices and signage in place to ensure that they don't become trapped, injured or killed.
The powered gate is a great addition to a work or residence. The costs associated with maintaining it safely on a daily basis, is always going to be less expensive and less traumatic than reacting after the fact, if an accident has occurred.
