We have had blocks provided to rest over the tracks for the compact shelving in order to ensure the stacks cannot close in on staff. The first blocks prepared are to be trialled in MB and Store A – Library and Archives. As the tracks are a known hazard we thought it was better to keep the blocks with the tracks. Please trial them if you work in these areas. Send any feedback to me for modification. These are for your increased safety if you choose to use them. Joan Simpson
