Aerial ladders with pre-paid waterways should typically be carried or pinned in which position?

When operating aerial ladders, particularly those with pre-paid waterways, it is essential to ensure that they are carried or pinned in the rescue of the second section position. This positioning optimally enables the firefighting team to quickly deploy the ladder for rescue operations while also maintaining ease of maneuverability and stability.

Positioning the pre-paid waterways in the second section allows the firefighters to maintain access to the ladder's controls and water supply while effectively positioning the ladder for victim access. Additionally, by keeping the waterways secured in this section, it minimizes the risk of entanglement or obstruction during deployment, leading to a safer and more efficient rescue operation.

The other options, while potentially workable in some scenarios, may not provide the same level of accessibility and safety during the critical moments of a rescue. Therefore, the second section is the most practical and effective choice for handling aerial ladders with pre-paid waterways.
