[wardenship] Lift emergency, contact info

Looking for help, suggestions and ideas. We are just considering how best to address the issue of the lift breaking down (with people inside) if there is no one else in the building? The lift call out charge for this is over £2,000 and beyond our means. We recognise that some people have a mobile and therefore have a means of outside contact if this situation arises. We wondered what other meetings do? In anticipation Amanda clerk of Sheffield Central Quakers. Amanda J Wells
