Posted By Renny Thomson TechSP If you're looking at lights as a warning to pedestrians, a much better solution is to use a method of segregating the two. If they have to co-habitate, most places insist on Hi-Viz clothing being worn. The vehicles must have good all-round vision, if not additional mirrors or reversing aids such as CCTV should be fitted to the vehicles. Relaince on drivers switching on the hazard lights, then expecting them to switch them off once exiting the site is not to be relied on in my opinion.

Posted By George Wedgwood We have sought opinion from our sector HSE and their experience is that quarries and aggregate plants have managed this very well with hazards on when entering and off when leaving. This is in addition to a wide range of other control measures like hi-viz, good site lighting, speed limits, warning signs, barriers and segregation where possible. So the majority of evidence points us to implementing it as part of our package to reduce risk and including the control in our site rules issued to all drivers. Thanks for your views and also to those who have emailed me direct. Regards, George
