BS EN ISO 11850:2011+A1:2016

What is ISO 11850 - General safety requirements for forestry machinery about ?

ISO 11850 is an international standard that serves general safety requirements for forestry machinery, ensuring safety and risk reduction in forestry applications. 

ISO 11850 specifies general safety requirements for self-propelled forestry machines and machines configured as forestry machines. 

ISO 11850 deals with all significant hazards, hazardous situations and events common to fellers, bunchers, delimbers, forwarders, log loaders, skidders, processors, harvesters, mulchers and multi-function versions of these machine types, when used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. 

Note: ISO 11850 does not apply to - 

• Hazards specific to individual machines 
• Hazards related to chain shot, chain breakage, the upper side of the bar, lifting operation 
• Hazards related to remote control operation, the need for work lights or road safety 
• Vibration measurement and noise measurement 
• Hazards related to maintenance or repairs by professional service personnel 
• Machines manufactured before the date of its publication 

Who is ISO 11850 - General safety requirements for forestry machinery for ?

ISO 11850 on general safety requirements for forestry machinery applies to: 

• Manufacturers of forestry machinery 
• Dealers and importers of forestry machinery 
• Testing houses and labs forestry machinery 

Why should you use ISO 11850 - General safety requirements for forestry machinery ?

Forestry machineries are complex mechanical and electrical machines that facilitate heavy tasks and processes related to forestry applications. Forestry machinery aid in heavy tasks such as felling, cutting, extraction, processing, loading and transportation. Fulfilling safety requirements for machinery ensures safe handling and operability in forestry applications. 

ISO 11850 provides users guidance on safety distances, guards, shields, operator station, controls, visibility, lighting, braking systems, steering systems, stability, fire risks and more, ensuring safety and protection in case of hazards. 

ISO 11850 provides users guidance on information for the use of machinery for forestry, including operator’s manual, marking and safety signs, that facilitates accurate information exchange and proper handling of the machinery. 

With obedience and compliance of ISO 11850, users can develop and assess safety systems in forestry machinery, ensuring operational safety, operability and longevity in forestry applications.
