Which document serves as a formal amendment to the Fire Department's operational directives?

The document that serves as a formal amendment to the Fire Department's operational directives is the Numbered Bulletin. Numbered Bulletins are specifically designed to communicate changes, updates, or specific instructions regarding the operations of the fire department. They function as official notifications, ensuring that all personnel are informed of new procedures or modifications to existing guidelines.

In contrast, an Incident Report is focused on documenting specific incidents and outcomes rather than serving as a guide for amending operational procedures. The Department Manual contains comprehensive policies and procedures, but it is not typically updated by means of direct amendments; instead, it serves as the foundational reference. Lastly, a Policy Statement may outline philosophies or guiding principles, but it does not serve as the mechanism for formal amendments to operational directives like a Numbered Bulletin does. Therefore, the Numbered Bulletin plays an essential role in the fire department's communication process regarding operational changes.
