Pickets should be what length to allow adequate anchoring?

The recommended length for pickets to allow for adequate anchoring is between 3 to 6 feet. This length ensures that the pickets can be securely driven into the ground to provide a stable connection point for various rigging setups in technical rescue situations. A length of 3 to 6 feet strikes a balance between being long enough to secure into the ground, offering sufficient resistance against lateral forces, while also not being so long that they become cumbersome to transport or handle during rescues. Properly utilizing pickets of this length helps maintain the safety and effectiveness of the rescue operation, making them a versatile option for anchoring in different environments and conditions.
