What is the team capacity for a 3:1 ratio system in a high line rescue?

In a high line rescue utilizing a 3:1 mechanical advantage system, the team capacity is determined by the number of personnel that can be safely supported while effectively managing the load. A 3:1 ratio indicates that for every 1 unit of force exerted on the load, 3 units are exerted back, allowing for easier lifting or movement of a person.

In this scenario, the standard practice is to calculate the team capacity based on the number of rescuers necessary to operate the system effectively while ensuring the safety of both the rescuers and the person being rescued. Generally speaking, a common guideline in rescue operations is to pair each rescuer with a corresponding load they are managing, taking into account safety ratios and operational effectiveness. A 3:1 system usually requires a larger team, but ideal operational procedure typically allows for ratios where one rescuer can effectively manage the load of up to six or more people depending on the specifics of the situation and safety protocols in place.

Thus, a team capacity of 6 people (the answer identified) reflects a realistic approach where a small team can operate a 3:1 system effectively, ensuring that the necessary manpower is available for the rescue operation without overburdening any single rescuer.
