VISIBLE ALARMS and ROUTES
Simply flashing lights in an area can be enough to warn of problems but there should be clear information given out in advance as to what the alarm signifies and what should be done.
Escape routes and symbols should be obvious and checked along all their length, including widths of spaces for wheelchair users.
Wheelchair refuges where users should wait, if assistance is needed, should be clearly marked. The management procedures in the area should clearly define what staff are to do in assisting people with disabilities.
