28. Every employer shall ensure that, where self-propelled work equipment may, while in motion, involve risk to the safety of persons—
(a)it has facilities for preventing its being started by an unauthorised person;
(b)it has appropriate facilities for minimising the consequences of a collision where there is more than one item of rail-mounted work equipment in motion at the same time;
(c)it has a device for braking and stopping;
(d)where safety constraints so require, emergency facilities operated by readily accessible controls or automatic systems are available for braking and stopping the work equipment in the event of failure of the main facility;
(e)where the driver’s direct field of vision is inadequate to ensure safety, there are adequate devices for improving his vision so far as is reasonably practicable;
(f)if provided for use at night or in dark places—
(i)it is equipped with lighting appropriate to the work to be carried out; and
(ii)is otherwise sufficiently safe for such use;
(g)if it, or anything carried or towed by it, constitutes a fire hazard and is liable to endanger employees, it carries appropriate fire-fighting equipment, unless such equipment is kept sufficiently close to it.
