What is the importance of the message, "DO NOT REMOVE BY ORDER OF THE FIRE MARSHAL," on a fire service tag?

The message "DO NOT REMOVE BY ORDER OF THE FIRE MARSHAL" on a fire service tag is crucial for compliance reasons. It alerts anyone who may come across the tag that it is a mandatory requirement set forth by a regulatory authority, specifically the fire marshal. This indicates that the tag is serving a compliance function, which could relate to ensuring that safety systems or equipment remain in place for inspections, maintenance, or operational readiness.

The presence of this message means that removing the tag could violate safety codes or regulations, potentially leading to safety issues or penalties. The compliance must be maintained so that the system stays in accordance with fire safety standards, ensuring the protection of life and property.

The other options present scenarios that do not align with the regulatory significance the tag embodies. For example, indicating that the system is in a trial phase or noting that it has passed inspection would not carry the same level of urgency regarding compliance and legal adherence. Similarly, marking it as not operational could be misleading, as the tag serves more as a reminder of compliance than an operational status indicator.
