Food processing machinery. Machinery for grinding and processing flour and semolina. Safety and hygiene requirements

BS EN 14958:2006+A1:2009 Food processing machinery. Machinery for grinding and processing flour and semolina. Safety and hygiene requirements

BS EN 14958 deals with the significant hazards, hazardous situations and events relevant to the following machinery for grinding and processing of flour and semolina, as defined in Clause 3: roller mills, plan sifters and rotary separators, air classifiers, rotating machines and impact machines.

The machines in the scope are stationery (not intended to be moved when in operation), have a capacity of at least 100 kg/h, and are intended for use in installations for grain processing, such as flour mills, semolina mills, grain cleaning and flaking plants.

BS EN 14958 deals with the significant hazards during commissioning, operation, cleaning and maintenance of the machines in the scope when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer.

BS EN 14958 does not apply to:

• Machines intended for household use or laboratory use
• Stone mills
• Equipment for dampening and heating
• Auxiliary equipment for conveying, weighting and bagging (without changing the characteristics of the products).

BS EN 14958 does not cover:

• Hazards related to decommissioning
• The hazards of the installations into which the machines are incorporated other than those directly related to the machines in the scope (e.g. start of the installation, disconnection of energy supply, need from an emergency stop device)
• Hazards due to the use of the machinery in a potentially explosive atmosphere (when producing this standard it has been assumed that the machinery in the scope, if designed and used in accordance with BS EN 14958, is not creating itself a hazardous atmosphere wholly of partly surrounding it).

BS EN 14958  does not apply to machines manufactured before the date of its publication.
