Wood handles must be regularly inspected for any signs of distress such as cracks, splinters, decay or looseness at its attachment points. Tool handles should never be recoated with paint or any opaque finish that prevents inspection.
Handles showing signs of distress must be removed from service and the handle replaced. Always keep in mind, wooden handles may break. Use with caution!
Even though handles are inspected wood has variation in grains which can cause weakness.
Always be aware of the possibility that a handle can break. Never place all of your weight onto a piece of equipment without properly supporting yourself.
Never stand under or near loads that are being lifted or being held by Jennys. Even though lifting tongs have been tested you never know when wood grain may let loose on the object being lifted.
