Hall gates act as the entrance door to the elevator car from the hall landing. They are a critical component of the elevating system due to their location and interaction with the public. For this reason it is very important that the mechanical and electrical components of hall gates are in proper working order at all times.
Figure 10: Malfunctioning Hall Gates
Since October 2014, there have been 4 hazards identified by BCSA safety officers during regular inspections that deal with hall gates. Two of these involve mechanical components, a failure of which could result in a pinching and shearing hazard, and are rated as major. The other two involve electrical components whose failure is more serious as it could lead to the elevator car moving up and down the elevator shaft while the hall gates remain in an open position and are therefore rated as severe.
In March, a BCSA safety officer had to fail the inspection of an elevating device after the hall interlocks that keep the door closed during operation were found to be not operating correctly. This hazard allowed the hall gates to be opened at any time during the operation of the elevator, which could result in a person falling into the elevator shaft or risk of shearing. The maintenance contractor was notified immediately to resolve the issue.
This hazard was the result of a lack of knowledge on the part of the person who had performed maintenance on the elevator. This hazard could be prevented by ensuring that only authorized and qualified personnel perform maintenance on the equipment and that these personnel fully understand the severity of such a hazard.
