Additionally, all these features improve the overall safety and security of the system. In addition to this, the electric interlocks also provide an additional safety provision of keeping the chute closed whenever unused. This design minimizes the risk of accidents and unauthorized access; thus, it fosters a safer environment for staff and residents. The self-latching mechanisms ensure that the doors of the linen chute system automatically close, thereby creating more convenience and efficiency in day-to-day operations.
