The American National Standards Institute (ANSI) has released the ANSI Z133 safety requirements which apply to arboriculutral operations. Components of a rigging system must be used within their Working Load Limits.
ISC blocks are ANSI compliant when used within the manufacturer Working Load Limits.
A green log weight chart will aid in determining the loads in tree rigging.
The full ANSI Z133 safety requirements are available on our tree care standards page.
