Final answer:
Before taking a system out of service, an impairment coordinator must place out of service tags appropriately, notify the Fire Department and the responsible person, and maintain the system in service until work begins.
Step-by-step explanation:
Before authorizing a system to go out of service, the impairment coordinator should undertake a series of preparatory actions to ensure safety and compliance. Among these, the coordinator is responsible for placing out of service tags at all necessary and appropriate locations to alert personnel of the non-operational status of the system. Additionally, it is crucial to notify the Fire Department and the person responsible for the building or area where the system will be impaired so that they can take necessary precautions.
It is also essential for the impairment coordinator to maintain the system in service until work is ready to begin. This means the system should continue to be operational to protect the property and individuals until the exact moment the maintenance or repairs are set to commence. By following these steps, the impairment coordinator ensures that the transition to the system being out of service is as safe and seamless as possible.
