September 2026: New Safety Standard for Firewood Processors in Wood Technology

Staying current with safety requirements is essential in the rapidly evolving wood technology sector. This September, a significant new standard—prEN 18181—addresses the safety of combined firewood processors in agricultural and forestry machinery. As wood processing becomes more sophisticated, adopting robust safety standards is vital for manufacturers, equipment managers, safety officers, and operators seeking to ensure both regulatory compliance and safe, efficient operations. Here’s what the new standard means for you.

Overview / Introduction

The wood technology industry is foundational to both forestry and agricultural economies across Europe and beyond. Equipment like firewood processors play a pivotal role in turning raw logs into usable fuel, but as these machines become more advanced and automated, the risks to users and bystanders increase. Standards are critical—they not only reduce accident rates and machinery downtime but also ensure products meet harmonized technical, environmental, and regulatory benchmarks.

This article breaks down the new prEN 18181 safety standard, outlining its scope, key requirements, and the practical impact on industry professionals. Whether you’re a manufacturer, compliance officer, engineer, or procurement specialist, you’ll find actionable insights on adopting this new guideline and maintaining best-in-class safety performance.

Detailed Standards Coverage

prEN 18181 – Safety for Combined Firewood Processors

Agricultural and forestry machinery – Combined firewood processors – Safety

Published by CEN on 2026-09-04, prEN 18181 sets a new benchmark by specifying safety requirements—and detailed verification procedures—for the design and construction of firewood processors. These machines are widely used for making firewood, integrating cutting (via circular saw or chain blade) and splitting (with horizontal movement using one or more splitting wedges) into a single operation. Notably, the standard excludes machines that require manual intervention for material transfer, vertical splitting actions, or feature accessories like separate conveyors that aren’t integral to the processor itself.

Scope and Application

• Applies to manual, semi-automatic, and fully automatic firewood processors.
• Covers machines equipped with integral infeed and outfeed conveyors and integral log lifting devices operated via “hold-to-run” controls.
• Focuses exclusively on processors designed so that one operator oversees the process, although secondary operators might participate in feeding or unloading.
• Does not apply to legacy machinery manufactured before publication.
• Excludes machinery with non-integral accessories or vertical splitting mechanisms.

Key Safety Requirements and Specifications

The standard’s core mandates include:

• Comprehensive hazard analysis (see Annex A): The standard lists all significant hazards—mechanical, electrical, ergonomic, noise, dust, and more—associated with firewood processing equipment.
• Control system reliability: All safety-related functions, such as starting, stopping, emergency stop, guards, and interlocking devices, must meet at least Category 1 of EN ISO 13849-1:2023 for performance level c or d, depending on the function’s criticality.
• Ergonomic controls: Controls and operator interfaces must comply with EN 894-series and EN ISO 14738 for user comfort and safety. Operator stations require sufficient clearance and visibility, with all controls clearly identified and accessible—even when working with large-dimension logs.
• Electrical, hydraulic, and noise requirements: All electrical systems must meet at least IP54 protection, with plugs and main switches at IP44. Hydraulic components, noise emission limits, and dust management have binding performance requirements.
• Guarding and secure mode: Guards must prevent operator contact with active saws, with “secure mode” functionality ensuring all hazardous machine movement stops when an interlock or guard is open. Particular dimensions and materials for guards are dictated to ensure efficacy and durability (e.g., replaceable lips for saw blade slots).
• Emergency stop provisions: Emergency stops are mandatory for automatic machines where the operator is not continuously present; their positioning and performance must follow EN ISO 13850 and EN 60204-1.
• User instructions and marking: Machines must be properly marked, and instruction manuals must be exhaustive, including all warnings, maintenance instructions, and explanations of all safety provisions.

Who Needs to Comply

• Manufacturers of new firewood processors, especially those integrating automatic or semi-automatic functionality.
• Procurement specialists involved in purchasing forestry and agricultural machinery.
• Operators and site managers using or supervising the installation and operation of firewood processors.
• Safety inspectors and market surveillance authorities responsible for machinery compliance.

Practical Implications for Implementation

By mandating precise requirements for control systems, electrical safety, ergonomic design, and guarding, the standard minimizes the risk of operator injury and unplanned downtime. It also streamlines conformity assessments, helping manufacturers align with EU Machinery Regulation (EU) 2023/1230 and other local legislation. Companies that implement prEN 18181 will benefit from a clear, harmonized framework for product design and safety assessment, making market entry, certification, and procurement decisions more straightforward.

Notable Changes Compared to Previous Requirements

• Enhanced focus on automation: prEN 18181 addresses new risks for semi-automatic and automatic firewood processors, including robust remote control requirements.
• Refined approach to integrated accessories: Only integral conveyors and lifting devices are regulated, while separate add-ons are excluded from core requirements.
• Alignment with current EU regulations: Incorporates references and risk analyses to support easier proof of compliance with EU Machinery Regulation.

Key highlights:

• Applies to all newly manufactured firewood processors after September 2026
• Covers manual, semi-automatic, and automatic machines
• Detailed prescriptions for control system category and operator safety features
• Enforces proper guarding, secure modes, and emergency stop protocols
• Requires clear marking and comprehensive instructions for end users

Industry Impact & Compliance

Impact on Businesses and Operations

The adoption of prEN 18181 is set to drive large-scale improvements in workplace safety, operational reliability, and regulatory compliance across wood technology. For businesses:

• Equipment manufacturers must revise design, documentation, and verification procedures to meet the new performance and safety criteria.
• Procurement teams will need to specify compliance with prEN 18181 in requests, purchase orders, and supplier contracts.
• Operators and maintenance staff will benefit from clearer instructions, reduced exposure to mechanical and ergonomic hazards, and minimized risks when performing routine tasks.

Compliance Considerations and Timelines

• Timeline: The standard is applicable to all new machines manufactured after September 2026.
• Documentation: Manufacturers must maintain documentation demonstrating conformity, including risk assessments, performance verification, marking records, and user instruction booklets.
