Study Notes
Selecting the Attack Stair
- When selecting the attack stair, consider the building layout, particularly in multistory residential buildings, as floor plans are often similar due to economic reasons.
- Recognizing patterns in building design and construction helps locate the fire's seat and nearest standpipe.
- Utilities like water, sewer, HVAC, and gas are often stacked vertically in multi-story buildings, creating a predictable layout.
- When confronted with zero visibility, dropping down a floor below the fire can help map the layout before entering the smoke-filled hall on the fire floor.
- Select the stair closest to the apartment on the floor below the fire to estimate the location of the fire apartment on the fire floor.
- Choose the closest standpipe riser when multiple are available, prioritizing accessibility and avoiding drawing fire towards the attack crew.
- Consider life hazards when selecting the standpipe riser.
- Selecting the closest stairway and standpipe minimizes travel distance for the attack crew.
- Advancing the hoseline through a stairway door blocks the door, turning the stairway into a chimney, potentially increasing smoke and heat flow.
- Using staircases remote from the fire as evacuation stairs can mitigate the chimney effect on the attack stair.
- The chimney effect can impact the operations of the attack crew due to smoke, heat, and potentially fire being drawn towards the open stairway door.
