In buildings such as hotels it may be advisable to improve security by making passengers from a basement transfer at the lobby before going on to the upper floors. These arrangements can be confusing to users, however, and adequate signage will be required. The physically handicapped are often dependent on elevators and care should be taken to ensure that their needs are met. Approximately 5 per cent of the adult population require special features, many of which would benefit the rest of the population as well. 3 Such features should be internationally standardized to allow manufacturers to produce uniform lines of elevators.
Most problems result from control operations.
Recently some elevator companies have responded to this need by developing special features for the handicapped. The following recommendations include such features. The floor number, in relief, located on the door frame at 1500 mm. Again, the buttons indicating floor numbers should be in relief, preferably buttons that depress and remain depressed until the desired floor has been reached. In the lobby a permanently fixed shelf should be installed at 1010 mm from finished floor level.
