Overview
EN 15811:2014 is a European Standard developed by CEN that sets forth safety requirements for fixed guards and interlocked guards, with or without guard locking, designed for moving transmission parts in agricultural machinery. This standard applies specifically to self-propelled ride-on machines and mounted, semi-mounted, or trailed machines used in agriculture. Its primary objective is to minimize the risk of mechanical hazards by ensuring the design and construction of guards meet stringent safety criteria. The standard also mandates manufacturers to provide relevant information on safe working practices, including residual risks.
The scope excludes guards for agricultural and forestry tractors, agricultural aircraft, lawn and garden equipment, and PTO drive shafts between tractors and implements. EN 15811:2014 is aligned with ISO/TS 28923:2012 but includes modifications tailored for European agricultural machinery.
Key Topics
Safety Requirements: Defines essential design and construction requirements for fixed guards that can be opened or removed using a tool, and interlocked guards which may include guard locking mechanisms. Guards must prevent access to moving power transmission parts that pose hazards such as crushing, shearing, entanglement, drawing-in, or trapping.
Risk Assessment Integration: Requires the selection of guards based on a thorough risk assessment conforming to EN ISO 12100 principles. The frequency of operator access to hazard zones is a key factor in deciding between fixed or interlocked guards.
Fixed Guards: Must be securely attached and require a tool for opening or removal. Safety signs warning of hazards and indications (visible or audible) must be provided when hazardous parts continue moving after power disengagement.
Interlocking Guards: Feature devices that prevent machine operation when guards are open and disengage hazardous parts automatically. For components with long run-down times, guard locking devices must keep guards locked until dangerous motion ceases.
Verification and Testing: Safety requirements need to be verified through inspections, measurements, and operational tests based on manufacturer manuals to ensure guards perform properly without introducing new risks like debris accumulation or hindering machine function.
Information for Users: Manufacturers must provide detailed operator manuals including warnings about residual risks, necessary training, and clear safety signage to promote safe working environments.
Applications
EN 15811:2014 is essential for manufacturers, designers, and safety engineers involved in the production and maintenance of agricultural machinery where moving power transmission parts pose mechanical hazards. Typical applications include:
- Self-propelled ride-on agricultural machines
- Mounted, semi-mounted, and trailed agricultural implements
- Machinery components requiring guarded access for maintenance or operation
- Safety audits and conformity assessments in agricultural equipment manufacturing
- Compliance with EU machinery directives to ensure market access in European countries
By following EN 15811, manufacturers can enhance workplace safety, reduce the risk of injury related to moving transmission parts, and meet regulatory compliance for agricultural machinery in Europe.
