Course: Firefighting I (15152-I) > Section: Using Ladders

Performance may include

- flat raise
- beam raise
- perpendicular raise
- parallel raise
- one-person flat raise
- two-person perpendicular raise using a wall ladder
- two-person perpendicular raise using an extension ladder
- two-person parallel beam raise using a wall ladder
- two-person parallel beam raise using an extension ladder
- two-person parallel flat raise using a wall ladder
- two-person parallel flat raise using an extension ladder
- two-person roof ladder raise for a one-story building
- two-person roof ladder raise for a two-story building
- three- or four-person perpendicular flat raise using an extension ladder
- five- or six-person perpendicular raise
- five- or six-person parallel raise
- overhead obstruction raise.

Performance should also include positioning the bottom of the ladder at a distance from a vertical plane equal to 1/4 the total working length of the ladder. The ideal ladder angle is 75.5 degrees.

Process/Skill Questions:

- How can a 75-degree angle be determined without an instrument?
- Why should the wind direction be determined prior to raising a ladder?
- How can a ladder be secured after it is raised?
