What were the handles of the siphona, which were up to 15 feet long, called?

The handles of the siphona, which were designed to be up to 15 feet long, are referred to as brakes. This terminology stems from the function these handles served during firefighting operations. In historical contexts, especially during fire suppression efforts, brakes were used to control and direct the flow of water from the siphona, which was an early firefighting apparatus.

Brakes allowed firefighters to manipulate the water stream effectively, exerting control over the distance and pressure with which the water was thrown onto a fire. The unique design and length of these handles were essential for maximizing reach and effectiveness while maintaining safety for the operators.

The other options do not accurately reflect the specific terminology or function associated with this historical firefighting tool. "Handles," while a generic term, does not convey the specialized function they served. "Pumps" implies a different mechanism used to move water, while "levers" suggests a pivoting mechanism rather than the control aspect associated with the siphona's operation. Thus, the term "brakes" is most appropriate for identifying these long handles and their distinctive role in fire control tactics.
