What size hand lines were initially stretched into the building?

The size of hand lines that are typically used in firefighting scenarios is crucial for effectively combating structural fires and ensuring the safety of both firefighters and victims. Using two 1 3/4" hand lines is standard because this size offers a balance between flow rate and manageability, allowing firefighters to maneuver effectively while delivering an adequate volume of water to suppress the fire.

1 3/4" hand lines provide sufficient pressure and volume for interior operations, which is especially important in residential and commercial structures where rapid suppression is necessary. The smaller diameter makes them easier to handle, particularly in confined spaces, and allows for quicker deployment. This makes them an ideal choice for initial attack lines in many situations.

Firefighters are trained to prioritize agility and speed in their response, which the 1 3/4" lines facilitate, ensuring that crews can quickly engage the fire and apply water effectively. The standard practice of using two lines provides a level of redundancy and additional flow, further enhancing the chances of successful fire suppression.
