How many floors can one section of a 100ft hose stretch through a stairwell?

A section of a 100ft hose is typically designed to allow for access and maneuverability within a stairwell while providing adequate reach to combat fires in multi-floor structures. When considering the height of floors in most buildings, it is generally accepted that each floor has a height of approximately 10 to 12 feet.

Given this standard floor height, a 100ft hose can effectively reach up to approximately 4 to 5 floors in total. However, accounting for factors such as bends in the hose when maneuvering through stairwells and the need to maintain accessibility for firefighters, the practical reach of a 100ft hose in a stairwell is typically facilitated through 4 floors. This means that while in theory, the hose could reach beyond this number, operational conditions usually limit its effective use in reaching up to about 4 floors.

Therefore, the understanding that a section of a 100ft hose can effectively navigate through and service fire response needs adequately across 4 floors underscores the correct answer.
