An incident report states: 'Upon arrival, Ladder 2 deployed an aerial apparatus to the B-side for potential ventilation and egress. Engine 1 initiated an offensive interior attack on the first floor, while Rescue 3 conducted a primary search of the second floor.' What does 'B-side' likely refer to in this context?

Question: An incident report states: 'Upon arrival, Ladder 2 deployed an aerial apparatus to the B-side for potential ventilation and egress. Engine 1 initiated an offensive interior attack on the first floor, while Rescue 3 conducted a primary search of the second floor.' What does 'B-side' likely refer to in this context?

Answer options:

• The back side of the structure. ✅ The left side of the structure from the alpha (front) side.
• The side facing the main street.
• The side where the emergency vehicle is parked.

Correct answer: The left side of the structure from the alpha (front) side.

Explanation: In fireground operations, sides of a structure are typically identified alphabetically starting from the front (Alpha side). The B-side would therefore be the left side when looking at the building from the Alpha side.
