Final answer:
The question about when to perform monthly pump checks per PS Trax cannot be answered without specific context, as such schedules are determined by individual organization policies or outlined in the PS Trax user manual or platform.
Step-by-step explanation:
The question refers to PS Trax, which appears to be a system for managing and tracking the maintenance activities such as monthly pump checks. However, without the specific context of the organization or field that uses PS Trax, it is not possible to provide a standardized answer. Such checks are typically set by the internal policies of a fire department, emergency services, facility management, or any other entity that utilizes pump equipment. It is usually the responsibility of the organization's maintenance team or individuals assigned to perform and document these checks according to the established schedule.
Please refer to your organization's specific guidelines or the user manual for PS Trax to find out when monthly pump checks should be conducted. If you have access to the platform, there might be a schedule or reminder feature that outlines when these checks are due.
