Health and Safety Policy: Stump Grinder and Stump Grinding Operations

Purpose: This policy sets out the core health and safety principles for the use, operation and maintenance of stump grinder machinery on sites where tree stump removal is undertaken. It explains responsibilities, safe working methods, and controls designed to prevent injury, damage and environmental harm during stump grinding work.

Scope and application: The policy applies to all personnel involved in stump grinding operations, including stump grinder operators, supervisors, machine maintenance staff, and contractors who work where stump grinders and related stump removal machinery are present. It is intended to be practical, risk-focused and adaptable to different site conditions.

Roles and responsibilities: Management must provide adequate resources, proper equipment and appropriate supervision. Operators are responsible for conducting pre-start checks and following safe operating procedures. Supervisors must ensure site-specific risk assessments are completed and that competent people carry out stump grinding activities with suitable training and authorization.

Risk assessment and planning

Before any stump grinding activity begins, a documented risk assessment must be carried out that considers the hazards unique to stump grinders, such as flying debris, buried utilities, unstable ground and proximity to people, buildings, vehicles and services. Plans should include access, egress, exclusion zones and a communication method for the work crew.

Operator competence: Only trained and assessed stump grinder operators are permitted to operate the equipment. Training should cover machine controls, emergency shutdown, safe approach and retreat, recognition of kickback and entanglement risks, and routine machine care. Refresher training and practical observation should be scheduled regularly.

Machine inspection and maintenance: A pre-use checklist must be completed for every shift and every machine. Key checks include cutting wheel condition, guards, controls, emergency stop function, fuel and hydraulic systems, and wheel bolts. Faults must be isolated, tagged and reported until repaired by authorised staff or a competent technician.

Personal protective equipment: Appropriate PPE is mandatory for stump grinding tasks. This includes, as a minimum, eye and face protection, hearing protection, cut-resistant gloves, safety footwear, high-visibility clothing and hard hats where overhead hazards exist. Operators should also consider leg protection and respiratory protection in dusty conditions.

Safe operating procedures: Operators must establish a stable working position, keep bystanders outside the exclusion zone, and approach grinding systematically to control chip ejection and machine stability. Stump grinding should be carried out at controlled speeds and with frequent reassessment to avoid overloading the machine or creating unstable stump fragments.

Environmental and site controls: Measures to mitigate noise, dust and surface water contamination must be applied. Use water suppression where practical and avoid operating over sensitive ground or near drains and watercourses. Minimise disturbance to surrounding vegetation and dispose of grindings and waste in accordance with environmental best practice.

Traffic and exclusion zones

Define and signpost exclusion zones around stump grinding operations. Where vehicles and pedestrians may cross the work area, implement traffic management plans that include banksman or spotter duties. Maintain a clear line of sight or use radio communication between the operator and ground staff.

Manual handling and ergonomics: When loading, positioning or removing parts of a stump or machine components, apply safe manual handling techniques and mechanical aids where possible. Consider machine attachments that reduce manual effort and ensure lifting tasks are risk assessed for weight, reach and posture.

Permits and utility checks: Ensure any necessary permits are obtained and that underground utilities have been located and marked before commencing stump removal. If suspected services are discovered during grinding, stop work immediately and follow the site’s service strike protocol.

Emergency procedures and first aid: Establish clear emergency response arrangements including access for emergency vehicles, on-site first aid provision and a procedure for dealing with serious incidents. Operators must be familiar with emergency shutdown controls and the process for securing a machine following an incident.

Incident reporting and investigation: All incidents, near misses and unsafe conditions must be reported without delay. Investigations should identify root causes and lead to corrective actions that are communicated to prevent recurrence. Use a simple reporting process to encourage timely reporting by the whole team.

Monitoring, review and continuous improvement: Health and safety performance for stump grinding operations should be monitored through inspections, audits and workplace observation. Policies and procedures must be reviewed following incidents, changes in equipment or practice, and at regular intervals. Continuous improvement is achieved through learning, training updates and investment in safer equipment.
