When minimum code is not enough

Unlike like residential elevators installed in Alberta, devices installed in public applications are required to be registered and inspected by AEDARSA. By doing this the industry is regulated, and devices installed all meet a minimum standard. There are however, situations where simply meeting code is not enough.




To install an inclined platform lift and not have an automatic folding platform seems ridiculous. If the intent of these lifts is to grant independence and ensure true barrier free access, manually folding platforms fall short of these goals.While some individuals have increased mobility,  how can we expect all wheelchair user to manually fold the lift up and down? This is a perfect example of meeting code, but not meeting the needs of the end user.


I am always perplexed when a see a specification that asks for the smallest platform available (while still meeting code). Why not specify the largest one available? This is very achievable when in the design phase. You would be surprised as to the impact on the end user, when 6 extra inches is added to the length of the lift platform. Under the B-355 code, accessibility lifts are able to have a platform as large as 21 square feet.


This lift has a pit so no ramp is necessary
Another situation I often run into is when a ramp is used at the lower landing rather than a 3 inch pit. This is sometimes necessary if the device is going into existing construction. If I see this specified on new construction, I always see if the ramp can be eliminated and a pit can be utilized. This is far easier for the end user to access the lift if they do not have to wheel up a ramp as they try to open the door. If the ramp is the only option then it is highly recommended that a power door operator be used.


This brings us to call stations and their installation location. If a power door operator is incorporated into a lift with a ramp, it is critical that the call station is located remotely - not in the door frame. B-355 elevators or lifts are required to operate on constant pressure controls, which means you have to constantly hold the button while calling the lift or operating the lift. If the call station is located in the path of a door swing this can be very difficult for the wheelchair user. If the call station is in the door frame and a ramp is incorporated into the design, it is almost impossible to wheel up the ramp, hold your position while you call the lift, and try to avoid the door as it swings open.

Other pet peeves include bi-folding doors with a track on the bottom (perfect for catching smaller walker wheels), improper egress as you exit the lift, and designs that do not consider an evacuation device for folks using wheelchairs.
