Learning Objective 3 15 Recognize the types of ladders used in the fire service Single ladders are also called wall or straight ladders

5 Roof ladders are equipped with folding hooks to anchor the ladder Folding ladders are often single ladders used for interior attic access Extension ladders are made up of a base section and fly sections Combination ladders are designed to be self-supporting

6 NFPA 1901 contains information on apparatus-mounted ground ladders REVIEW QUESTION How do the five types of ladders used in the fire service compare with one another? Learning Objective 4 23 Explain the considerations addressed by ladder inspection, cleaning, and maintenance Some elements must be inspected on all types of ladders

7 25 WARNING Any ladder that has been subjected to direct flame contact, has been exposed to high heat, or has a heat sensor label that has changed color is unsafe for use and should be removed from service for testing There are inspection elements specific to each type of ladder CAUTION Any indication of deterioration of the wood is reason for the ladder to be removed from service until it can be service tested Once inspection is complete, select the correct procedure to follow

8 Service testing must be performed to ensure a ladder is fit for use REVIEW QUESTION What types of information do general ladder inspections look for? Cleaning is more than just a matter of appearance, it can also impact function Maintenance and repair are two different processes firefighters should understand

9 REVIEW QUESTION 33 What are the general maintenance requirements for ground ladders? Learning Objective 5 34 Describe safety guidelines used when handling ladders Learning Objective 6 35 Explain considerations taken when selecting, lifting, and lowering a ladder There are several ladder safety guidelines firefighters should know. 36 (Cont.) 12 36

10 37 WARNING Ladders coming in contact with power sources may result in electrocution of anyone in contact with the ladder There are several ladder safety guidelines firefighters should know. 38 (Cont.) There are several ladder safety guidelines firefighters should know. 39 (Cont.) WARNING Sliding down a ladder either feet first or head first even in an emergency is unsafe and may result in serious injury or death

11 There are several ladder safety guidelines firefighters should know REVIEW QUESTION What are the guidelines for safely carrying, raising, lowering, and working on ladders? The IC considers several factors when deciding where to place the ladder Ladder selection also requires other important information

12 45 There are several guidelines to use for ladder length selection A ladder s reach is not the same as the designated length REVIEW QUESTION What factors must be considered when selecting a ladder placement location? Use proper lifting and lowering techniques to prevent personal injuries

13 49 REVIEW QUESTION What techniques should be used to prevent personal injuries when lifting and lowering ladders? Learning Objective 7 50 Describe various methods for ladder carries Ladder carry requirements vary depending on the type Methods to remove ladders from apparatus depend on ladder location

14 53 DISCUSSION QUESTIONS How are the ground ladders mounted on the different apparatus in your jurisdiction? Have you observed ladders being removed from racks, compartments, or a mechanically operated rack? Firefighters must know certain information when using ground ladders on apparatus Procedures for removing side and top mounted ladders differ from flat mounted ladders REVIEW QUESTION What information must a firefighter know in order to use ground ladders? 12 56

15 The one-firefighter low-shoulder carry is for some single and roof ladders CAUTION Carrying the forward end of a ladder at eye level impedes the carrier s balance and visibility and increases the risk of the butt spurs striking someone else in the head The two-firefighter low-shoulder carry is also for some single and roof ladders The three-firefighter flat-shoulder carry is typically used on extension ladders

16 The three-firefighter flat arm s length carry begins with the fly section up The four-firefighter flat-shoulder carry is similar to the three person method The two-firefighter arm s length on-edge carry is best with lightweight ladders There are some general procedures to use for carrying roof ladders

17 Learning Objective 8 65 Identify basic considerations and requirements for ground ladder placement Ladder placement responsibilities are often shared by different personnel There are two objectives when placing ground ladders Positioning will vary based on the task being accomplished

18 Other ladder placement guidelines are also important to know. 69 (Cont.) Other ladder placement guidelines are also important to know. 70 (Cont.) Other ladder placement guidelines are also important to know REVIEW QUESTION What are the two objectives that must be met when placing ground ladders? 12 72

19 The distance of the butt end from the building is what determines ladder angle There are several ways to determine proper distance for ladder angles REVIEW QUESTION 75 How can a firefighter determine the proper distance between the heel of the ladder and the building? Learning Objective 9 76 Describe various methods for ladder raises

20 Methods for ladder raises require teamwork, smoothness, and rhythm The transition from ladder carry to raise should be done in one smooth motion Several considerations must be addressed before raising a ladder. 79 (Cont.) WARNING All ladders will conduct electricity, especially when wet, regardless of their construction material

21 Several considerations must be addressed before raising a ladder. 81 (Cont.) Several considerations must be addressed before raising a ladder The one-firefighter raise can be used for both single and extension ladders There is little difference if the ladder is parallel or perpendicular to the building for two-firefighter raises

22 The three-firefighter flat raise can be used for heavier ladders The four-firefighter flat raise can be used for heavier extension ladders There are a number of ways a roof ladder can be deployed REVIEW QUESTION What considerations must be addressed before raising a ladder? 12 88

23 Learning Objective Compare procedures for moving ground ladders Two firefighters are required to pivot a ladder when needed Shifting raised ground ladders should be limited to short distances REVIEW QUESTION What are two methods of safely moving a ground ladder after it has been raised? 12 92

24 Learning Objective Explain the methods used to secure ladders Ground ladders must be secured whenever firefighters are climbing or working from the ladder There are several methods that can be used for heeling a ladder Tying in secures the ladder to a fixed object and should be done if possible

25 REVIEW QUESTION 97 How do the two methods used for securing ladders compare with one another? Learning Objective Describe ladder climbing considerations There are several factors to consider when climbing ladders. 99 (Cont.) There are several factors to consider when climbing ladders

26 101 REVIEW QUESTION How can a firefighter climb a ladder so that there is the least possible amount of bounce and sway? Learning Objective Indicate what methods can be used to work from a ladder Firefighters may be required to work with both hands while standing on a ground ladder WARNING Do not exceed the rated load capacity of the ladder. To avoid overloading the ladder, allow only one firefighter on each section of a ladder at the same time. Be careful about stressing ladders laterally
