Safety of machinery - Fire prevention and protection

This European Standard specifies methods of identification of the fire hazard resulting from machinery and the performance of a corresponding risk assessment. It specifies the basic concepts and methodology of technical measures for fire prevention and protection to be taken during the design and construction of machinery. The
purpose of this European Standard is to reach the required safety level according to the intended use of the machinery by applying technical measures for machinery (see Figure 1, column 1). Technical measures are mainly integrated in the machinery and they are preferably implemented by use of safety components as defined in
Directive 98/37/EC.
This European Standard is applicable to the machinery given in the Council Directive of 22 June 1998 on the approximation of the laws of the Member States relating to machinery (98/37/EC). The exclusions given in this Directive are also relevant to this European Standard. This European Standard does not cover machinery designed to contain controlled combustion processes (e.g. internal combustion engines, furnaces), unless these processes may constitute the ignition source of a fire in other
parts of the machinery or outside of this.

Sicherheit von Maschinen - Brandschutz

Diese Europäische Norm legtspezifiziert Methoden zum Erkennen der von Bränden an Maschinen ausgehenden Gefahren und ihre Zuordnung mittels einer entsprechenden Risikobeurteilung fest. Sie legtspezifiziert die grundlegenden Begriffe und Methoden technischer Brandschutzmaßnahmen fest, die für die Konstruktion und Fertigung von Maschinen erforderlich sind. Das Ziel dieser Europäischen Norm ist es, das für die bestimmungsgemäße Verwendung der Maschine erforderliche Sicherheitsniveau durch Anwendung technischer Maßnahmen an der Maschine zu erreichen (siehe Bild 1, Spalte 1). Bei technischen Brandschutzmaßnahmen handelt es sich vorwiegend um in die Maschine integrierte Maßnahmen in Form von Sicherheitsbauteilen, wie sie in der Maschinenrichtlinie (98/37/EG) definiert sind.
Diese Europäische Norm gilt für Maschinen entsprechend der Richtlinie des Rates vom 1998-06-22 zur Angleichung der Rechtsvorschriften der Mitgliedstaaten für Maschinen (98/37/EG). Die Ausschlüsse, die in dieser Richtlinie enthalten sind, gelten auch für diese Europäische Norm.
Diese Europäische Norm gilt nicht für Maschinen für kontrollierte Verbrennungsprozesse (z. B. Verbrennungsmotoren, Öfen), es sei denn, dass diese Prozesse die Zündquelle für einen Brand in anderen Teilen der Maschine oder außerhalb derselben sein können.

Sécurité des machines - Prévention et protection contre l'incendie

La présente Norme européenne spécifie les méthodes d'identification du risque d'incendie provenant des
machines ainsi que la réalisation de l'estimation du risque correspondant. Elle spécifie les concepts de base
et la méthodologie des mesures techniques à prendre pour la prévention et la protection contre l'incendie
lors de la conception et de la construction des machines. L'objectif de cette Norme européenne est
d'atteindre le niveau de sécurité exigé compte tenu du domaine d'utilisation visé par des mesures techniques
des machines (voir Figure 1, colonne 1). Les mesures techniques sont principalement intégrées aux
machines et sont de préférence mises en oeuvre avec des composants de sécurité tels que définis dans
!les Directives 98/37/CE et 2006/42/CE".
La présente Norme européenne s'applique aux machines traitées dans la Directive du Conseil du 22 juin
1998 concernant le rapprochement des législations des États membres pour ce qui concerne les machines
(!Directives 98/37/CE et 2006/42/CE"). Les exclusions données dans cette Directive sont également
applicables à la présente Norme européenne.
La présente Norme européenne ne s'applique pas aux machines conçues pour maîtriser des procédés de
combustion contrôlée (par exemple moteurs à combustion interne, fours), à moins que ces procédés ne
puissent constituer une source d'allumage d'un incendie dans d’autres parties de la machine ou en dehors
de celle-ci.

This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). !For relationship with EU Directive(s), see informative Annexes ZA and ZB, which are integral parts of this document." According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.



EN 13478:2001+A1:2008 (E) 4 Introduction The safety of machinery against fire involves fire prevention and protection and fire-fighting. In general, these include technical (Figure 1, column 1), structural (Figure 1, column 2), organizational (Figure 1, column 3), works (Figure 1, column 4) and public fire fighting (Figure 1, column 5) measures. Effective fire safety of machinery can require the implementation of a single measure or a combination of measures. CEN and CENELEC are producing a set of standards to assist designers, manufacturers and other interested bodies to interpret the essential safety requirements in order to achieve conformity with European Legislation. Within this series of standards CEN has undertaken to draw up a standard to give guidance in the field of fire prevention and protection, as hazards from fire are to be considered in accordance with 4.8 of EN 292-1:1991. This European Standard was drawn up on request and by mandate of CEC and EFTA to fulfil the Council Directive on the approximation of the laws of the member states relating to machinery (98/37/EC) which demands in its Annex I, 1.5.6 that machinery shall be so designed and constructed to avoid any risk of fire. In accordance with EN 292-1 it is a type B standard. CEN/TC 114 has a mandate in this area to produce A-type and B-type standards, which will allow verification of conformity with the essential safety requirements.

Figure 2 — Fire-Triangle



EN 13478:2001+A1:2008 (E) 10 The fire hazard depends on the interaction of these three items. Certain materials are inherently unstable, extraordinary oxidizers or capable of self-heating. This affects the fire hazard. Variation in oxygen concentration (e.g. oxygen enrichment) can also significantly affect the fire hazard. The fire hazard can arise from the materials processed, used or released by the machinery, from materials in the vicinity of the machinery, or from materials used in the construction of the machinery. WARNING An explosion hazard can exist in addition to the fire hazard (see EN 1127-1 and prEN 1127-2). 4.2 Combustible materials Combustible materials can occur as solids, liquids or gases. It shall be determined whether combustible materials exist or can exist and in what quantity and distribution. The ease of combustion of materials is affected by the size, shape and deposition of the materials. For example, small pieces of a material loosely collected together can be more easily ignited than a large piece of that material. Also the combination of materials can have an influence on the ignitability and the burning behaviour. Consideration shall be given as to whether the properties of the materials can change over time or with use. Such changes can include the possibility of decomposition of the material releasing combustible gases and vapours. This can lead to an increased fire hazard. 4.3 Oxidizers In assessing the fire hazard, the existence and quantity of fire supporting substances, e.g. oxygen producing substances and the probability of their occurrence shall be determined. The most common oxidizer is air. But there are other oxidizers which support combustion e.g. Potassium Nitrate (KNO3), Potassium Permanganate (KMnO4), Perchloric acid (HClO4), Hydrogen Peroxide (H2O2), Nitrous Oxide (N2O). 4.4 Ignition sources It shall be determined which ignition sources exist or can occur. Possible ignition sources can arise due to the influence of:
a) heat energy;
b) electrical energy;
c) mechanical energy;
d) chemical energy. 5 Requirements for risk assessment
5.1 General Determination and evaluation of the fire risk requires a sequence of logical steps allowing systematic examination of the fire hazards arising from the machinery and/or the work process according to the procedures outlined in EN 1050. It includes risk analysis and risk evaluation. The risk evaluation establishes if risk reduction measures are required. see annex A for examples



EN 13478:2001+A1:2008 (E) 11 5.2 Risk analysis The risk of fire in machinery shall be determined by analysis. It depends on the existence of a fire hazard, the probability of its occurrence and the degree of the possible harm. Analysis of fire risk shall include the following elements (see also Figure 3):  list of all materials involved in the machine and process, including raw and process materials;  evaluation of their ignitability, flammability, combustibility, fire supporting effect and toxic issues;  determination of the fire load;  list of all possible ignition sources;  determination of fire scenarios according to fire loads and ignition sources;  evaluation of possible fire risks caused by human errors such as exchange of substances and wrong handling of controls. Information on the fire properties of the materials or components used in a machine can often be found from the technical literature or the supplier. In some cases however, appropriate testing of the materials or components can be required.

EN 13478:2001+A1:2008 (E) 12 5.3 Risk evaluation After fire risk analysis, the fire risk shall be evaluated taking into account the expected harm. This can result e.g. from the fire itself, thermal radiation, the fire effluent, or escaping materials. If the evaluation of the fire risk results in the conclusion that the machine is not safe, risk reduction measures shall be implemented. The evaluation of the level of damage to property or environment relies on economical, technical and regulatory factors. These factors shall be taken into account in deciding on the technical fire prevention and protection measures needed. 5.4 Risk reduction If risk reduction measures are required, it shall be decided whether and which technical measures shall be taken to reduce the risk of fire and/or to limit the effects of a fire. After each technical measure taken to reduce the risk of fire, a risk analysis shall be performed again until the machine is safe following the process defined in EN 1050. Technical fire prevention and protection measures do not cover the overall risk at the machinery in question, and therefore care shall be taken that the measures applied do not increase other risks. 6 Requirements for technical fire prevention and protection measures for machinery
6.1 General Technical fire prevention and protection measures (see Figure 1, column 1) comprise:  design and/or engineering measures;  integrated fire detection and fire fighting systems;  additional measures;  information for use. The measures shall be applied in the above order of priority and in accordance with the procedures of EN 292-1:1991, clause 5 (see 7.1 and Figure 4). 6.2 Design/engineering measures Risk reduction shall be primarily achieved by design/engineering measures which eliminate or minimize the fire hazard. These comprise the following: a) The use of materials in the construction of the machine which are non combustible, non flammable and/or have reduced combustibility/flammability e.g. flame retardant materials; NOTE
Suitable test methods for reacting to fire and a fire classification system for construction products and building elements are given e.g. in prEN 13501-1. b) Elimination or minimization of the risk of overheating, either of the machine itself, or of the materials, be they gases, liquids, solids, dusts or vapours, produced or used by the machine. The risk is analysed by consideration of the process deviations which might lead to overheating. Elimination or minimization of the risk is realized by identifying how such deviations are detected or controlled, and implementing the means to achieve this; c) The choice of materials for the construction of the machine in which their adverse interaction with the materials produced or used by the machine is eliminated or minimized;



EN 13478:2001+A1:2008 (E) 13 d) The design of the machine to avoid combustible or fire supporting concentrations, or accumulations of raw material, intermediate product, or product which exceed the required quantities for that machine; e) Where the possibility of a fire can not be eliminated, the effects of that fire, including flames, heat and smoke etc., shall be limited for example by shielding or enclosure of the machine to eliminate or minimize the risk of injury to persons and/or damage to property and/or the environment. The requirements according to EN 292-1 shall be applicable. 6.3 Use of integrated fire detection and fire fighting systems Risk reduction is achieved by appropriate use of integrated fire detection and fire fighting systems (safety components), which comprise devices for the detection, control, alarm and extinguishing functions. The requirements shall be determined according to fig. 5. An example of a safety component consisting of a detector, central alarm control unit, storage unit and discharge pipework and nozzles is given in annex B. The severity of harm is essentially determined by the rate of growth of the fire and its duration. The fire should be detected as soon as possible and the extinguishing procedure should be initiated with the minimum of delay following fire detection. If persons can be endangered, e.g. where toxic extinguishants are used, due regard shall be given to the safety of persons in the area of the machine and/or in the machine itself. These measures should be taken to ensure that a fire (damaging fire) is extinguished or limited as far as possible to the area of its occurrence. 6.4 Additional measures It can be appropriate to provide additional fire prevention and protection measures. Additional measures can be e.g.:  programmed shut-down of the machinery and/or of auxiliary equipment, including isolation of all non-essential raw materials and products;  emergency stop of the machinery, isolation of non-essential power supplies, e. g electrical supplies and fuel supplies;  isolation of the protected area covered by the fire fighting system, e.g. by an enclosure or water curtain.
If necessary, retention or collecting devices for the fire effluents and extinguishing agents used in the event of a fire shall be provided. 6.5 Information for use Comprehensive and understandable documentation shall be provided to the user in order to ensure that he can keep the machinery, installations and the technical fire protection equipment in a proper condition and ready for operation and, where necessary, initiate the required fire fighting measures. Information of the commissioning, operation and maintenance of the technical fire prevention and protection measures with respect to the intended use of the machine (as required in accordance with EN 292-2:1991, clause 5) and warnings of any residual fire risks shall be provided. If it is a special requirement of the user, that the fire prevention and protection of the machinery is at least partly intended to rely on an existing fire protection provision of the user, then the interfaces shall be defined and described in the operating instructions. In determining the possible damage to property and the environment, the manufacturer of the machine shall state the installation requirements assumed for the machine, including its location. If the user does not follow these, it is for the user to assess the possible damage to his property and the environment caused by propagation of the fire beyond the confines of the machine, to affect the surrounding area, including other plant and/or buildings. This assessment can modify the determination of the level of damage (low, medium, high) (see 7.3.3) and can require corrective action by the user.



EN 13478:2001+A1:2008 (E) 14 7 Requirements for the selection and design of technical fire prevention and protection measures 7.1 Procedure In selecting and designing technical fire prevention and protection measures with the aim of reducing the risk, several steps shall be taken by the iterative process according to EN 1050. These steps shall comprise the following as shown in Figure 4: Step 1: Risk assessment  Risk analysis with respect to fire at a machine in all operation modes and in each phase of its service life according to EN 292 and EN 1050 (see 5.2);  Evaluation of the risk arising through the fire hazards and decision on adequate risk reduction for this application in accordance with EN 292 and EN 1050 (see 5.3). If the machine is considered to be safe the iterative process is finished and the information for use has to be completed.
