BS EN 12779:2004+A1:2009 Safety of woodworking machines - Chip and dust extraction systems with fixed installation - Safety related performances and safety requirements
This document sets out the safety related performance requirements and specifies the methods for elimination of hazards or the measures that shall be taken to minimise hazards, which cannot be eliminated, on chip and dust extraction systems with fixed installation as defined in 3.1.1 and 3.1.2, for the purpose of this standard, hereinafter referred to as extraction system, connected to woodworking machines, designed to process solid
wood, chipboard, fibreboard, plywood and also these materials where these are covered with plastic laminate or edgings. The extraction and conveying system operates pneumatically by vacuum and/or pressure between ± 0,3 bar.
This standard does not:
a) apply to fixed installations with an air flow capacity below 6 000 m3h-1 installed indoors;
b) apply to moveable units with an air flow capacity below 6 000 mh;
c) apply to extraction equipment (e.g. extraction hoods, ducts) within a woodworking machine i.e. up to and including the outlet to which the extraction system is coupled;
d) apply to extraction systems connected to machines processing non-wood materials, such as plastic,
plastic laminates, metals, glass or stone;
e) deal with the hazards from contact with or inhalation of dusts from wood coated with lacquer, plastic, aluminium and material with high additive contents or similar;
f) deal with shop fresh air supply;
g) apply to chip and dust extraction systems designed for Kst values above 200 bar ms;
h) apply to the silo discharge system;
i) cover the hazards related to Electromagnetic Compatibility (EMC) as required by the EMC Directive
89/336/EEC dated 3-5-89.
This document deals with the interaction with the silo discharge system if any.
This document covers the hazards relevant to these machines as stated in Clause 4 document Directive 94/9/EC concerning equipment and protective systems intended for use in potentially explosive atmospheres can be applicable to the type of machine or equipment covered by this document.
The present standard is not intended to provide means of complying with the Essential Health and Safety Requirements (EHSR) of Directive 94/9/EC.
This European Standard is not applicable to machines which are manufactured before the date of its
publication as EN.
