Wood Chipper Safety Shield Program Expands Across JPIA Membership
Following the California JPIA’s launch of funding for the Wood Chipper Safety Shield (WCSS), members throughout the state are taking proactive steps to enhance employee safety around one of the most hazardous pieces of equipment used in public works, parks, and urban forestry operations.
The WCSS uses magnetic proximity technology to help prevent operator entanglement. Sensors installed in the chipper’s infeed hopper detect magnetic wrist and ankle bands worn by employees. If a band crosses the safety plane, the feed rollers immediately stop, providing an added engineering control during chipper operations.
Each funded WCSS installation includes the device itself, eight magnetic Velcro wrist and ankle bands equipping two operators, and on-site safety orientation training. Members operating multiple wood chippers are encouraged to evaluate whether additional units should be installed so each chipper has the same level of protection.
Member Agencies Share Early Feedback
Several California JPIA members have installed the WCSS and reported positive operational experiences, including appreciation for the added safety measure, orientation training, and integration into existing safety practices.
City of San Marino: The agency reported a smooth implementation and no operational concerns following installation. “The WCSS works well, and we have had no issues at all.”
City of Paso Robles: Staff noted value in both the safety equipment and the on-site orientation provided during installation. “No issues with the WCSS at all, it works fine for us, and we appreciate the extra safety it provides. In addition, we really appreciate the orientation you gave. The additional training was good for us, and we have implemented what you recommended.”
City of Pismo Beach: Their experience underscores how the system can reinforce safer positioning around the chipper during operations. “The crew said it took getting used to because they were used to going beyond the safety plane of the chipper, and this action would stop the feeding due to the WCSS. Now that they have some time using it, they have no issues and appreciate the extra safety added to the chipper.”
City of Chino Hills: They used the installation to refresh procedures, reinforce expectations, and communicate the change to employees. “All on board. We actually did a PowerPoint presentation to all of our workers and implemented new policies and procedures for using the chipper after the WCSS was installed. We have had no issues with the WCSS.”
City of Santa Fe Springs: Staff reported successful installation and operation of the WCSS. “We have had no issue with the WCSS being installed on our chipper. It works well.”
Recent JPIA Member Installations
Recent installations have included the cities of Lomita, Duarte, Cerritos, Santa Clarita, San Luis Obispo, San Dimas, Arroyo Grande, Pismo Beach, Paso Robles, Chino Hills, San Marino, San Juan Capistrano, and Santa Fe Springs.
Funds Remain Available
The California JPIA continues to fund the purchase and installation of one WCSS per member operating a wood chipper, subject to available funding. The approximate value of each system is $5,000 to $7,000.
Funding is available on a first-come, first-served basis until allocated funds are exhausted. Members operating wood chippers are encouraged to contact their regional risk manager to request installation and confirm availability.
While training, personal protective equipment, and safe work procedures remain essential, the WCSS provides an additional engineering control that can help reduce the risk of catastrophic injury during wood chipper operations.
To request a WCSS installation, contact your regional risk manager.
