During operations, which side of the building does an engine company typically use during an ally drop?

The Charlie side of a building typically refers to the rear or the side opposite the primary entrance (which is usually designated the Alpha side). In firefighting operations, especially when deploying hose lines or performing an alley drop, using the Charlie side offers strategic advantages. It allows fire crews to gain access to the building from a less visible angle, minimizing exposure to hazards such as fire or smoke that may be more concentrated on the Alpha side. Additionally, this position can help in avoiding traffic and provide a clearer path for the fire apparatus and personnel to maneuver.

In many operations, the Charlie side is used because it can provide an effective approach for attack crews and also helps in setting up aerial apparatus if needed. The context and layout of the fire scene often dictate this choice to maintain operational efficiency and safety.

The other sides, designated as Alpha, Bravo, and Delta, have specific roles and may be more susceptible to direct access issues or hazards presented by the incident, such as active fire conditions at the primary entrance or side.
