Product Overview

Summary: This Limb Chipping Safe Operating Procedure sets out safe, consistent methods for processing tree limbs and green waste using mechanical chippers. It helps Australian businesses control the significant risks associated with high‑powered chipping equipment, kickback, entanglement and flying debris, while maintaining productivity on arborist, vegetation management and civil works sites.

Limb chipping is a high‑risk task that combines powerful cutting mechanisms, variable site conditions and close proximity of workers and the public. Without a clear, documented procedure, crews can easily fall into unsafe habits such as overloading the hopper, reaching into feed areas, working too close to traffic, or operating in poor communication with the chipper operator. This Limb Chipping Safe Operating Procedure provides a structured, step‑by‑step approach to planning, setting up and carrying out limb chipping activities in line with Australian WHS expectations.

The SOP guides your team through pre‑start inspections, safe positioning of the chipper, exclusion zones, traffic and pedestrian control, manual handling of limbs, and correct feeding techniques to prevent entanglement and kickback. It also addresses noise, dust and plant interface risks, as well as shutdown and maintenance requirements. By implementing this procedure, businesses can demonstrate due diligence, streamline training for new crew members, and significantly reduce the likelihood of serious injuries, property damage, and regulatory non‑compliance on worksites where limb chipping is undertaken.

Key Benefits

• Ensure limb chipping operations are carried out in accordance with Australian WHS legislation and industry best practice.
• Reduce the risk of serious injuries from entanglement, contact with moving parts, flying debris and uncontrolled limb movement.
• Standardise work methods across crews, improving communication, efficiency and job quality on every site.
• Support effective induction and competency assessment for new and existing workers involved in limb chipping.
• Demonstrate documented risk controls to clients, regulators and insurers, helping protect your business reputation and contracts.
