Study Notes

Laddering Overview

Laddering is not just about placing ladders against buildings; it should serve a specific purpose in firefighting operations.
Ladder placement should be strategic, as unwarranted placements can waste time and resources.

Portable Ladders

Portable ladders provide access, rescue routes, and ventilation points, often replacing aerial devices when vehicle access is limited.
Effective use of portable ladders can prevent fatalities, limit fire extension, and ease firefighters’ tasks.
Familiarity with department ladder types is essential for effective deployment during emergencies.

Selecting Portable Ladders

Factors in ladder selection include reach, weight, material, nested length, and personnel required for handling.
Ladder length is the most critical factor; a ladder must be able to reach the intended location to be effective.
An area assessment is necessary to identify lengths needed for specific locations, especially where aerial devices can't reach.

Ladder Types and Length

Common combinations of ladders for fire crews include multiple extension ladders of varying lengths to meet different building heights.
Extension ladders are versatile, replacing several other ladder lengths with their adjustable reach.
Average residential buildings require a ladder length of about 13 ft to reach second-floor windowsills.

Proper Placement and Use

Proper tip placement is crucial based on the use case (e.g., entry, rescue, ventilation).
The ideal climbing angle for portable ladders is approximately 70° to maintain stability while climbing.
Optimal tip placement for rescue or entry is just at or slightly below the windowsill for maximum efficiency.

Material of Construction

Most modern fire service ladders are made of aluminum, offering lightweight and less maintenance.
Wooden ladders are becoming rare due to their weight and maintenance issues.
Aluminum ladders can weaken under extreme heat; heat-indicating labels on ladders help monitor exposure to dangerous temperatures.

Safe Ladder Usage

Recognize and adhere to standard ladder terminology and operational procedures.
Annual inspections and proper training are fundamental to ensure effectiveness and safety in ladder operations.
Never overload ladders beyond the maximum capacity of 750 lbs, except for folding and attic ladders.

Climbing and Working on Ladders

Always maintain three points of contact when climbing a ladder: two feet and one hand.
Use safety measures like ladder locks or belts to secure yourself while working to prevent falls.
Avoid reaching beyond the ladder's length to reduce the risk of falls caused by overextension or ladder movement.

Additional Safety Guidelines

Always position ladders away from electrical lines to prevent electrocution.
Secure the base or tip of a ladder in windy conditions or when leaving it unattended to prevent tipping.
Before stepping off a ladder, ensure the stability of the landing area, probing if necessary, regardless of visibility conditions.
