Additionally, when using a winch in chipper operations, the operator shall ensure that the winch line is properly stored before initiating chipper operations. This study aimed to determine whether accreditation and certification are associated with safety practices and to identify specific safety practices adhered to most and least.

These are just a few of the revisions in the updated Z If maintenance is needed, all moving parts shall come to a complete stop and keys shall be removed from the ignition and pocketed by the authorized person before proceeding.

The same now applies to aerial lift operators when pruning. Intervention strategies are needed for all company types for the use of PPE and safer use of chain saws and chippers.

Also important to note, the wheel chock guideline previously stated that wheel chocks need to be set before using an aerial device — the new standard specifies two wheel chocks.

Compliance with the ANSI Z – safety standard among arborists in New England.

Radio communications shall be hands free. When working with chipper winches, a winch line should not be wrapped around a load. Arboriculture is hazardous work. As for other equipment, znsi revision restates that equipment must be inspected before use, but goes further to suggest that if an inspection reveals a defect that could affect the safe operation of the equipment, the equipment shall be removed from service.

Greater attention to PPE, chain saw, and chipper practices is warranted across the industry.

Companies with accreditation or certified arborists demonstrated greater safety compliance than those without. Only partial compliance was found among accredited companies and companies with certified arborists.

The purpose of requiring a handsaw while aloft is make a strong asi for an alternative practice i.

ANSI Z Revision Overview

Electrical hazards One of the most notable changes is in section 4 — Electrical Hazards — specifically the expansion of the rules for working in proximity to electrical hazards to recognize three levels of qualification: During winching operations of loads that do not have a manufactured attachment point, the load should be secured using a sling.

For example, the climber is now required to have a hand saw available while working aloft, where previously it was only a recommendation. Chippers and winches received a lot of attention in the revisions. Use of vehicles and mobile equipment Chippers and winches received a lot of attention in the revisions. One of the most notable changes is in section 4 — Electrical Hazards — specifically the expansion of the rules for working in proximity to electrical hazards to recognize three levels of qualification:
