What are butt spurs on a ladder?

Butt spurs on a ladder refer to spikes or protrusions located at the base of the ladder that provide stability and prevent slipping when the ladder is in use. These physical features enhance traction on various surfaces, reducing the risk of accidents by ensuring that the ladder remains securely positioned during operation. This design is particularly important when the ladder is placed on surfaces that could be slippery or uneven, allowing for safer climbing and working practices.

The other options do not accurately describe the function or design of butt spurs. The first choice describes features that would actually hinder safety, while the second refers to components related to the ladder's extension system, which is unrelated to stability at the base. The third option mentions wear and tear rather than the design intended to maintain traction. Understanding the role of butt spurs is crucial for ensuring the safe use of ladders in firefighting and rescue operations.
