The regulator says the guidance needs to be followed if safety around powered gates is to be maintained.
In 2010, two children died after becoming trapped in powered gates. This was because they were not detected at the closing edge of the gates, and because the closing force of the gate was too high.
In response the HSE issued two safety notices explaining the risks of such gates and what steps can be taken to protect employees and members of the public.
The guidance includes checking a gate is maintained by a reputable company who regularly test its safety features, asking a gate maintenance company to show how the gate can be released in an emergency, and asking them to highlight safety features, like safety edges, guards and light beams.
"If you are purchasing a new gate, check that the installer can show you the features explained above, and that they will CE mark the gate and issue you a Declaration of Conformity," the HSE said.
"If they are unsure about how to do this it may be a reason to doubt their competence."
