Agricultural machinery - Safety - Part 19: Livestock feed and bedding machines
Abstract
This document, used together with ISO 4254-1, specifies the safety requirements and their verification for the design and construction of livestock feed and bedding machines that have a combination of two or more of the following functions loading, mixing, chopping and distributing materials . In addition, it specifies the type of information on safe working practices to be provided by the manufacturer. NOTE Livestock feed and bedding machines (for example feed mixers, bale processors, silage block cutters) can be stationary, mounted, semi-mounted, interchangeable towed or self-propelled. When requirements of this document are different from those which are stated in ISO 4254-1, the requirements of this document take precedence over the requirements of ISO 4254-1 for machines that have been designed and built according to the requirements of this document. This part of ISO 4254 is not applicable to: - machines which pick up or transport crop material directly from the field; - loading cranes; -automated, semi-autonomous and autonomous functions (for example, those covered by ISO 3991) - the integrity of safety-related parts of control systems in relation to the specification of performance levels; - environmental hazards (excluding noise), road safety and hazards associated with moving transmission parts; - hazards associated with maintenance or repairs carried out by professional service personnel. This document deals with the significant hazards, hazardous situations and events relevant to machines for loading, mixing and/or chopping and distributing silage and/or other feedstuffs, when they are used as intended and under the conditions foreseen by the manufacturer as listed in Annex A, except for the hazards arising from: - failure of the control circuit; - inadequate seating; - inadequate lighting; - travelling of machinery related to road safety; - break-up of parts rotating at high speed; This document is not applicable to machines manufactured before the date of publication of this document. Examples of machines and components covered by this document are shown in Annex B.
