Sam Hill Tree Care's Andrew Wimmel selected to serve on Accredited Standards Committee


SamHill-headshot-2.pngSam Hill Tree Care Production and Safety Manager Andrew Wimmel has been selected to serve on the Accredited Standards Committee (ASC) ANSI Z133 as of November, 2017.

As part of the prestigious committee that sets safety standard guidelines, Wimmel will join a 30-member group twice yearly as they review and revise the ANSI Z133 guidelines. Committee delegates include representatives from industry, labor, academia, government, equipment manufacturing, the insurance industry, individual arborists and other interested parties.

“I’m honored to be part of this group,” said Wimmel. “From my very first day in the field shadowing Sam Hill on job sites, I was reminded of the importance of personal safety for the individual and the company.”

According to Wimmel, the tree pruning profession is one of the most dangerous industries in the nation and when someone gets injured it is often a serious situation. Wimmel emphasizes the value of the American National Standard for Aboricultural Operations – Safety Requirements (Z133).

Although compliance with this standard is voluntary, Z133 carries the force of law in many instances in the U.S. when OSHA cannot find language in its own standards to guide safe work practices in a particular situation they will typically cite a section of Z133 as what the employer "should have known or done” to create a safe work environment for its employees.

“Sam instilled the importance of proper procedures early in my employment,” said Wimmel.  “And now, I have an incredible opportunity to give back to the community at large.”

“When we step onto an individual’s property, we want to ensure the safety for everyone in the area including our employees, customers and any individual that might come in contact with our crew during Arboriculture Operations,” said Wimmel.
