Posted By Steven Taylor Hi can anyone help. Our engineers are starting to plan out fitting edge protection to all the roofs in our premises, are their any standards on the dimensions of the edge protection. i.e height, length between each section, height of kick board etc. Thanks in advance

Posted By peter gotch Steven, The appropriate distance between adjacent "standards" would depend on various factors including whether the edge protection is to be tied to the roof or to be free standing + e.g. if the latter what sort of arrangements are made to weight the supports down. Taking into account increasing height of workforce, I would have top guard-rail minimum 1100mm above roof surface + mid-rail + toe-board or similar minimum 150mm height above surface. Maximum unprotected gap between rails or between mid-rail and toe-board 470mm. According to Specialist Inspector Report no 15 "“Design Loadings for Temporary Roof and Floor Edge Protection” (out of print - but with no obvious alternate guidance) indicates that for a roof such as this with a pitch (ie slope) of up to 100, a free standing temporary roof edge protection structure should be capable of withstanding a point load of 0.7kN without fracture or disconnecting. US equivalent standard is 0.89kN (or thereby) but their workforce is on average heavier. Any reason why your engineers don't just go out and buy a tried and tested system, that has been designed with future maintenance in mind, e.g. that marketed by Safesite.

Posted By Steven Taylor Thanks for the responses. Peter, our engineering department don't like to spend money on "off the shelf" products if it can be made in house much cheaper (they also don't learn from history). The edge protection to be fitted is for working off a flat roof and will be a permanent fix, the roof is also within a building so shouldn't have any wind problems. I've looked at the web-site you suggested and it mentions counter weights at 4m intervals, what does it mean by this?
