Stationary Fire Pumps Handbook
|Publication Date:||1 January 2016|
The Overview of this handbook provides examples of various fire pump configurations and explains the purpose of the components of those pumps. Each component and its location in a fire pump assembly affects the fire pump's performance and its ability to meet the demands of the fire suppression system. When designing a fire pump assembly, the fire pump room must be evaluated to determine the best orientation of the pump and its components, and all the installation requirements of this standard must be met. If the pump and components are not arranged with adequate space and clearances allowing for proper operation, maintenance, and mobility - if the controllers were located at the back of the pump room, for instance - the pump operator could be at risk of injury. Locating the controllers close to the pump room exit and providing the required clearances allows the operator to quickly engage the emergency shutoff and evacuate the room. Exhibit 1 depicts a fire pump controller installed in the back corner of a fire pump room, a location that could put an operator at risk of injury. Note that the access and egress are obstructed by piping and components, making it difficult to escape during an emergency.
