ALWAYS set up a 1-1-1 system in direct line with the load.
ALWAYS Tip pickets away from the load "heel to toe" and space one picket length apart.
ALWAYS drive pickets 2/3rds deep. If the pickets won't drive to proper depth, choose a different location.
ALWAYS safety check a 1-1-1 system for proper rigging before applying a load.
ALWAYS observe the pickets for movement or shifting when the load is applied or if the load changes significantly, such as getting hung up during the haul.
Whenever practical use a second anchor point with a progress capture device as a safety line when operating on steeper slopes.
