Question

Before authorizing a system to go out of service which of the following shall be performed by the impairment coordinator?

a. System Test
b. Risk Assessment
c. Notification to Authorities
d. Documentation

Answer 1

The impairment coordinator must perform a risk assessment before authorizing a system to go out of service.

Step-by-step explanation:

Before authorizing a system to go out of service, the impairment coordinator shall perform a risk assessment. The risk assessment includes evaluating potential hazards, the impact on the facility and its occupants, and determining the necessary steps to mitigate the risks during the period the system will be out of service. This assessment essentially ensures that all safety, security, and operational impacts are considered before the system is taken offline.

Moreover, while all the options listed are important in the impairment coordination process, the risk assessment step is crucial before the authorization as it informs the other steps, such as System Test, Notification to Authorities, and Documentation.

Answer 2

The impairment coordinator must perform a risk assessment before a system goes out of service, documenting the reasons and details of the shutdown, and potentially notifying relevant authorities depending on legal and safety requirements.

Step-by-step explanation:

Before authorizing a system to go out of service, the impairment coordinator shall perform a risk assessment. This assessment is crucial as it evaluates the potential impact on building operations and safety. The process typically involves analyzing the effects of the system being out of service, considering alternative safety measures, and determining the duration of impairment.

Additionally, documentation is required to record the specifics of the impairment, including the reason for the system shutdown and details of the risk assessment. This documentation must be comprehensive to ensure accountability and maintain a legal and procedural record of actions taken. To comply with legal and safety requirements, the impairment coordinator might also need to notify the relevant authorities depending on the type of system being impaired and the regulations in force. However, it is not always a step taken before the system shutdown, but rather a component of the response plan based on the risk assessment's outcome.
