What type of portable ladder has permanently attached curved metal hooks?

1. Extension ladder

2. Roof ladder

3. Folding ladder

4. Step ladder

The correct answer is: Roof ladder

A roof ladder is designed specifically for firefighting and has permanently attached curved metal hooks, which are used to secure the ladder to the roof during operations. These hooks allow firefighters to stabilize the ladder against the roof's peak, ensuring safety and preventing slippage while they carry out their tasks. This design is crucial for maintaining balance and support when maneuvering on potentially unstable surfaces such as roofs during emergency situations. In contrast, an extension ladder does not have hooks and is designed to extend its length for reaching higher elevations. A folding ladder typically features a hinge mechanism that allows it to be compacted for storage or transportation, lacking the specialized features of a roof ladder. A step ladder, primarily used for tasks requiring elevation at a low height, does not include any climbing aids for roofs and is generally not used in firefighting scenarios. Thus, the characteristics and intended use of a roof ladder clearly distinguish it as the correct answer.
