What type of ladder is commonly used for reaching a second story of a building?

• A. Step ladder
• B. Extension ladder
• C. Folding ladder
• D. Rope ladder

Answer: (B)

An extension ladder is specifically designed to reach higher surfaces, such as the second story of a building. These ladders can be extended and are typically capable of reaching significant heights while maintaining stability and strength. The design allows firefighters to adjust the length of the ladder based on the height of the structure they need to access, making it a versatile and essential tool for firefighting and rescue operations. In contrast, step ladders are shorter and are generally used for tasks that require less elevation, making them unsuitable for reaching upper floors. Folding ladders are typically more compact and may not provide the necessary height or stability required for two-story access. Rope ladders, while they can be used in some situations, lack the support and structured design that an extension ladder offers, presenting safety concerns when it comes to ascending and descending from higher levels safely. Thus, the extension ladder emerges as the most practical and commonly used option for accessing a second story.
