Our unit's automatic decompression mechanism has been deactivated and can't be reactivated by anyone at the facility. Does its status still have to be continuously displayed?<
No. If that mechanism has been disabled and can’t be reactivated by the operators then, in our view, the unit does not have an automatic decompression mechanism. Because the requirement for a continuous display, like all the other requirements in this section, applies only to units with an automatic decompression mechanism, your unit does not have to have such a display. Should the automatic decompression mechanism be reactivated in the future, then your unit would have to meet all applicable requirements, including the requirement for a continuous display of the override status.
FDA recommends that the fact that the automatic decompression mechanism has been disabled, be indicated by a label on the control panel so that all operators, old and new, are fully aware of this.
