Our local Supermarket has a lift from the basememt car-park up to Ground Level Stuck on the wall of the lift is a paper sign giving a Phone number to call in case of an emergency. This implies to me that the Emergency System is not working. I believe the regs say there should be a permanant means of communicating with the rescue service. Ones mobile phone - if it would work, does not seem to be this solution.
Speaking to the manager he didn't seem to understand my concer and though te phone number was the Lift engineer!
