Yup, I am a voting member of the Z133 Committee. There are lots of changes happening.
The harness standard is really complex and i don't understand it well enough to make much of a comment either.
There is an OSHA reg that says that body support gear needs to be 5k#. this is not as easy to establish a proper work-around procedure like ANSI standards. OSHA regs are set...
We have to remember that the comps are not work and are work related to some degree. The TCC is a sporting event. this gives the organizers discretion about how to apply regs.
Today we talked a bit about the TxTCC which is this weekend. The most important issue is to have consistency and agreement on the given day.

The whole OSHA/ANSI requirement thing can be very confusing even to professionals. As a Petzl Work & Rescue Sales Rep I still can't keep it all straight. A discussion on this subject should be valuable to help all of us understand it better. So here goes...
To my understanding the Tree Care industry is regulated by OSHA. OSHA refers to ANSI Standards in its regulations. I think one of the things that complicates this whole issue is that ANSI Z359.1 is a fall arrest standard originally created by the construction industry. When OSHA began looking at Tree Care this was the only harness standard in existence. So they chose to hold the Tree Care Industry to this standard even though Tree Care harnesses are used for Work Positioning, not Fall Arrest. So as long as you are using your harness for Work Positioning and not Fall Arrest, OSHA does not require you to wear an ANSI certified harness. (Someone who has a better understanding of this, please correct me if I am wrong.)
If ISA chooses to require ANSI Z359.1 certification to CYA regarding liability at comps, that is their choice. Right or wrong, their intent is good even though the tools they are using do not actually apply.
The Fire Service looks to NFPA for guidance. NFPA refers to ANSI standards as well. The difference is that NFPA only makes "recommendations". Fire Departments are not compelled to follow these recommendations, particularly if they can justify their choices. A common mis-conception throughout the Fire Service is that NFPA makes requirements. They do not.
Clearly, it is ok for an arborist to use a Petzl Sequoia harness for work even though it is not ANSI certified. But ISA will not allow its use in a sanctioned competition because it is not certified?
The best thing for the Tree Care Industry would be standards that apply to Tree Care. Additionally, international standards for Tree Care should be considered as U.S. and CE standards are often close but do not match further complicating the issue for all of us.
Any ANSI experts out there care to comment?
