Which type of ladder is excluded from the annual service test?

Pompier and folding ladders are indeed excluded from the annual service test for ladders. This exclusion is based on their design and typical use; these ladders are often used in specialized situations where structural integrity is tested differently than conventional ladders. Pompier ladders, which are typically lightweight and portable, and folding ladders, which may not be employed in the same high-stress environments as other ladders, do not require the same rigorous testing protocols which are important for ensuring the safety and performance of more heavily used ladder types.

In contrast, extension ladders, step ladders, and roof ladders are subject to annual service tests because they are commonly used in many firefighting and rescue scenarios. These tests help ensure that all structural components, including rungs and locks, remain in safe working condition. Regular testing is critical for maintaining the safety and reliability of these ladders as they undergo wear and tear during routine operations, making it vital to adhere to the testing protocols established for them.
