ANSI Z133 2017 Revision Overview
As for other equipment, the revision restates that equipment must be inspected before use, but goes further to suggest that if an anei reveals a defect that could affect the safe operation of the equipment, the equipment shall be removed from service. Sixty-three tree care companies in southern New England ani directly observed on job sites.
Radio communications shall be hands free. Radio communications between the qualified arborist and qualified crane operator shall be used during blind picks. Use of vehicles annsi mobile equipment Chippers and winches received a lot of attention in the revisions.
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.
These are just a few of the revisions in the updated Z This is z13.1 sizeable expansion on the topic from the previous version, and specifically details the safety requirements of each of these tree worker positions.
Intervention strategies are needed for all company types for the use of PPE and safer use of chain saws and chippers.
However, low compliance was found across all company types for personal protective equipment PPE use, chain saw safety, and chipper safety. The purpose of requiring a handsaw while aloft is make a strong suggestion for an alternative practice i. Greater attention to PPE, chain saw, and chipper practices is warranted across the industry. Climbing The following changes pertaining to climbers are relatively simple and straightforward.
The following changes pertaining to climbers are relatively simple and straightforward.
The same now applies to aerial lift operators when pruning. A consensus safety standard exists, but little is known about compliance with it. Safety in non-accredited companies without certified arborists especially needs improvement.
This study aimed to determine whether accreditation and certification are ansl with safety practices and to identify specific safety practices adhered to most and least.
When working with chipper winches, a winch line should not be wrapped around a load. The expansion on this requirement clarifies that only one worker shall be cutting a single tree or single tree part during the limbing and bucking process. The following are a small selection of changes in the revision: This essentially means that if the truck is over-loaded on a tree job, the driver is responsible.
ANSI Z Revision Overview
Although compliance with this standard is voluntary, Z carries the force of law in many instances in the U. During winching operations of loads that do not have a manufactured attachment point, the load should be secured using a sling.
This revision provides the most current and comprehensive safety guidance for arborists in the United States. To fully familiarize yourself with the revisions, we recommend picking up a copy, currently available in the Anso Shop.
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: Companies with accreditation or certified arborists demonstrated greater safety compliance than those without.
When more than one worker is involved in limbing, bucking and moving debris from a tree, each shall be positioned and their duties organized so that the actions of one worker will not create a hazard for any other worker. For example, the climber is now required to have a hand saw available while working aloft, where previously it was only a recommendation.
Additionally, when using a winch in chipper operations, the operator shall ensure that the winch line is properly stored before initiating chipper operations. 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.
Chippers and winches received a lot of attention in the revisions. For instance, the use of chippers by arborists, mechanics and other workers includes the following clarification in the revision: Only partial compliance was found among accredited companies and companies with certified arborists.
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: Arboriculture is hazardous work.
