For therealization and certification of these enclosures, you need to contact Palazzoli.The enclosure dimensions depends on the power dissipation of the devices inside the enclosure.TerminalsCable glands
  27. 27. 25ENCLOSURES AND CABLE GLANDSb) Number, type and dispositions of the cable glandsEach enclosure can be drilled on the 4 sides with a maximum number of entries that depends on the hole diameter and theside length and depth.On TAIS-EX thermosetting enclosures it is necessary to drill through holes and use cable glands with long thread and the relativenut. The holes must be drilled with specific tools for the thermosetting, such as the cup shaped milling cutters equipped withquick special steel drill connection with tungsten carbide gear teeth code 538410, in order to avoid splinters and irrregularitieson the hole profile.On ALUPRES-EX aluminium alloy enclosures it is possible to predispose the threading to directly screw the cable gland. On thesides with free window, you must use flanges predisposed for the threading passage or the blind ones to be drilled.In the table below, there are indicated the sides of the enclosure with free window and opening type.CODEDIMENSIONS(BxHxD)MAXIMUM NUMBER OF CABLE GLANDS THAT CAN BE INSTALLED ON EACH SIDELONG SIDE OF THE ENCLOSURE (B) SHORT SIDE OF THE ENCLOSURE (H)M16 M20 M25 M32 M40 M50 M16 M20 M25 M32 M40 M50532200EX 185x125x125 8 6 3 2 2 - 4 3 2 1 1 -532201EX 190x185x125 8 6 3 2 2 - 8 6 3 2 2 -532202EX 250x185x125 14 12 5 4 3 - 8 6 3 2 2 -532203EX 290x185x125 16 14 6 5 4 - 8 6 3 2 2 -532204EX 380x185x125 24 22 9 7 6 - 8 6 3 2 2 -532035EX 92x92x68 1 1 - - - - 1 1 - - - -532045EX 125x92x68 3 3 2 - - - 1 1 - - - -532055EX 185x92x68 4 4 2 - - - 1 1 - - - -532116EX 125x125x100 4 3 2 1 1 - 4 3 2 1 1 -532117EX 185x125x100 8 6 3 2 2 1 4 3 2 1 1 -532118EX 250x125x100 14 12 6 4 3 - 4 3 2 1 1 -532005EX 92x92x100 1 1 - - - - 1 1 - - - -532006EX 125x92x100 3 3 2 - - - 1 1 - - - -532015EX 185x92x100 4 4 2 - - - 1 1 - - - -532016EX 125x125x125 5 4 2 1 - - 5 4 2 1 - -532017EX 185x125x125 7 6 4 3 - - 5 4 2 1 - -532018EX 250x125x125 10 8 5 4 - - 5 4 2 1 - -511910EX 92x92x77 2 2 1 - - 2 2 1 - - -511913EX 125x125x113 5 4 2 2 - - 5 4 2 2 - -150021EX 155x155x73 6 5 3 1 - - 6 5 3 1 - -511920EX 185x185x145 12 10 8 4 3 2 12 10 8 4 3 2511921EX 252x185x145 16 14 10 5 4 3 12 10 8 4 3 2511911EX 125x92x77 3 2 2 - - - - - F0 - - -511912EX 185x92x77 4 3 2 - - - - - F0 - - -511917EX 252x125x113 9 8 5 4 - - - - F1 F1 - -511922EX 220x220x108 - - - - F3 - - - - - F3 -511923EX 252x252x197 - - - - - F5 24 18 12 7 6 3The above instructions are based on calculations of power dissipation relative to the maximum values prescribed by thestandards in force.Giving precise information about the terminal boards compositions, cables, currents, cable glands disposition and types,PALAZZOLI CAN REALIZE CUSTOMIZED SOLUTIONS, on request.

  54. 54. 521. ORIGINS AND REGULATIONS1.1 IntroductionHistorically, workplace risks from electric devices originated at the beginning of 1900s, when formations of firedamp incoal and sulphur mines led to many disasters.An explosion of methane gas (firedamp, also called mine gas) in a coal mine caused the death thousands of workers.Investigations were conducted in order to establish the causes of the accidents, they showed that the explosion wasprovoked by the low-voltage signal system used to communicate the readiness of the coal trolleys to climb from thebottom to the surface of the mine.This system, composed of low voltage batteries and a siren, and wiring running along the tunnels, was believed to besafe as it was working on low voltage and low current.However, it was clear that without protection, the inductive energy magazined in the siren, and in the wiring itself,would produce sufficient levels of energy to create a spark and consequently, an explosion of the dangerous mixtureof air and gas.Therefore, the electric device and the circuits associated to it, had to be constructed in new ways to mitigate futurerisks, and protect against possible damage of the devices themselves.Evidently these types of risk do not occur only in the mining sector, petroleum and chemical industries presentobviously risks, but also a lot of food, agriculture and manufacturing and finishing industries generate as part of theirnormal daily routines of atmospheres of dust and unfavorable mixtures, that are potentially explosive.1.2 Relevance – Modern studies about fires and explosions in ItalyPercentage of deaths due to fires and explosions(Period 2007-2011)Fires76%Explosions24%Foodstuffs12%Various16%Pharmaceutics5%Chemistry21%Fireworks46%All deaths 686All deaths 164All deaths 43Deaths due to explosions in industries in Italy(Breakdown regarding typology - Period 2007-2011)Deaths due to explosions in Italy(Breakdown regarding typology - Period 2007-2011)Deaths due to explosions in Italy(Annual Breakdown in relation to the typology) Residences Industries Railways Commercial activities Agricultural activities Auto Various Storages
  55. 55. 53Even today, a hundred years or so later, these matters still concern us – take for example, the measure of the tragicrelevance that is confronted in the present technical study that is taken from the official research that analyzes theamount of fatalities and injuries in Italy in the period 2007 – 2011.These statistics from Eng. Maurizio D’Addato, Director of the National Fire-watchers’ Corps.They show immediately entity and dimension of the problem taken as a whole and then in a detailed way focuses onsectors and typologies.1.3 Short normative history - ATEXThe first Italian regulation regarding flameproof electric plants is from 1955 (D.P.R. 547). One year after the directive CEI23-4 acknowledged the way of protection from explosions, 13 years later confirmed in the CEI 31-1, the first Directiveof Committee 31 aligned with recommendations IEC and CENELEC.This initial choice, followed by almost 40 years of lack of new directives, conditioned the Italian electric plant design thatremained on the level of syllogism till 1994: flameproof = explosion protection, however it was acknowledged just onthe formal level. Because of the community obligation, also other ways of protection were strengthening in Europe andin the United States.The ATEX directive, published in 1994, but definitely in function just from the 1st July 2003, broke with the past andestablished four firm points:1. The directive itself establishes the minimum requirements of protection, that even though are coherent with thedirective in force, they are not strictly bound to it.2. In all places that are classified as dangerous in the aspect of risk of explosion for the presence of gas or dust,restrictions concerning requirements of security need to be followed.3. The danger is divided into three levels and each of them concerns a particular category of requirements: thecategory 1 covers the level of the highest risk (zone 0 and 20), the category 2 – the level of high risk (zone 1 and21), the category 3 – from the quantitative point of view is the most important one, the level of risk is defined as“normal” (zone 2 and 22). The definition “normal” is not accidental; indeed all directives of the Community imposethe highest possible levels of prevention from the formation of explosive atmospheres, in other words in normalconditions there should exist just zones 2 and 22.4. The declaration of conformity that meets the requirements of security has to refer to the standard or new wayof protection and to the above-mentioned categories and needs to be accompanied with a way of control ofmanufacturing that guarantees the continuity of meeting such requirements during the production.For effect of the point 1 it is not necessary to expect that the new directives would recognize new ways of protection togain the certification as the directive contains sufficient and detailed indications.For effect of the point 2 there are not acknowledged anymore old implants AD-T and AD-FT based on the waterproofingstandards IP55 and IP44, now replaced with the ones in a way of protection Ex n G and D.For effect of the point 3 the old Directive CEI 64-23 had to be replaced by new CEI 31-30 and 31-34 that introducemore rational criterion of determination of the zone 2 amplifying considerably the field of the use of requirements of thecategory 3 to which belong the typologies Ex n.For effect of the point 4 the guarantee is extended to production and not only to the prototype subordinate to the verifyingentity; in particular the way of control of manufacturing, to put in disposition of authorities in charge to supervise, forcompanies with the certification ISO 9000 becomes a certified commitment.At last, it can be added that the new approach ATEX offers to the user the major guarantees of security togetherwith possibility to graduate costs for the explosion protection to the effective entity of danger; in the meantime freesthe technological research from rigid subjugation to the directive that have frequently excessive and daunting time ofpreparation and transposition.
  56. 56. 54In this new approach there are collocated the constructions Ex n G and D represented by Palazzoli, appropriate to manyrequirements of the directive ATEX and of the constructive norms CEI EN that refer to the explosion-proof technologyof the III generation.Difference between previous normative and ATEX1.4 Directives AtexThe principles of security against explosion are included in two Community directives known as Directives Atex: Directive1999/92/EC and Directive 94/9/EC.The attainment of the acceptable level is a result of the analysis of risk and in particular of minimization of two factors thatinfluence the likeliness of explosion, that is: the likeliness of the formation of explosive atmospheres and the likelihoodof the presence of sparks.The eevaluation of the likelihood of the explosive formation determines the subdivision in Zones of danger according tothe origin of the explosive atmosphere in the presence of gas and dust (Directive 1999/92/EC). The evaluation of thelikeliness of sparks in the explosive atmosphere determines the protection from the trigger of the explosive atmosphereby means of electric devices and/or components constructed in a way of protection that guarantees a level of securitythat corresponds to right zone of danger (Directive 94/9/EC). The prescriptions of security of devices to install inhazardous zones are also addressed to non-electric equipments.As follows there are illustrated all fundamental points of the two directives.1.4.1 Directive 1999/92/ECThe directive 1999/92/EC is a social directive that was submitted after consultation with the Advisory Committee onSafety and Health Protection at Work. It aims to ensure the minimum requirements of safety of workers at risk fromexplosive atmospheres. These objectives are prosecuted through the evaluation of the explosion risk and of thetechniques to minimize the presence of the explosive atmospheres and sparks. Shortly we can say that it is under thedirective 89/391/CEE, only that instead of occupying with workplaces in general, regulates specific provisions to followin places potentially at risk from explosive atmospheres.The directive provides a classification of risk in zones, that refer to the employer and the areas in which can be producedexplosive atmospheres and it determines groups and categories of equipments that can be used in each zone. Theclassification of areas is based on the frequency and the duration of the presence of explosive atmospheres.The directive establishes the minimum requirements for improving the safety and health protection of workers potentiallyat risk from explosive atmospheres. These requirements are explicit through determined obligations that have to beabsolved by the employer. In particular, the employer has to evaluate the explosion risks, at the same time taking intoconsideration:petrol petrolsomemeterBefore Now

If necessary, these areas are supposedto be signed that are at explosion risk.Sign that identifies an area in which an explosive atmosphere can be formed1.4.2. Directive 94/9/ECThe 94/9/EC is a directive of product whose objectives of Essential Safety Requirements (ESR) are related to theconstruction of electrical and non-electrical equipment in order not to be a source of the sparks in explosive atmospheres,depending on the likelihood of the presence of explosive atmospheres. The principal recipients of the directive areManufacturer or Importer of the device, anybody that enters in the market of the European Community, a product thatis meant to be installed in the explosive atmosphere.The directive 94/9/EC concerns all equipments that are supposed to be installed in places at risk of explosion, bothelectrical and non-electrical (mechanical) equipments.It is a directive of “new approach” as it does not furnish specific techniques, but essential safety requirements, inconnection with articles of the principal test.In the field of application there are included:- equipments: machines, materials, fixed and mobile devices, control devices, instrumentation and systems ofdetection and prevention that alone or combined are used in the production, transport, storage, measurement,regulation and conversion of energy and transformation of material and that because of the sources of sparks areat risk of explosion;- safety systems: safety, control and regulation devices that are meant to be used outside of explosive atmospheresbut they are necessary and useful to the safe functioning of devices and protection systems as far as it concernsthe explosion risks (barrier Ex “i”);- protection systems: devices that differ from components of the above defined devices, whose function is to blockexplosions in their source and/or circumscribe the zone in which they occurred;- components: essential pieces to the safe functioning of devices and protection systems without autonomousfunctioning.
  58. 58. 562.1 ExplosionAn explosion is a reaction of oxidation. The reaction of oxidation, that can be defined as combustion, provokes theformation of heat that is usually accompanied by visible flame. The combustion is an exothermic redox which meansthat a compound tarnishes while the other reduces releasing energy and forms new compounds, mostly carbon dioxideand water. For example, in the case of hydrocarbons, carbon tarnishes and oxygen reduces.The principal products of combustion are:• high emission of heat (exothermic reaction);• high emission of gas at high temperature.The reaction happens only if there are the three following components present (at the same place and at the same time):• fuel: substances in the form of gas, vapour, fog or dust;• combustive agent: it is an oxidative agent, usually oxygen present in the air;• ignition sources: any event (spark, flame, temperature, etc.) that is a source of energy.The fuel and the combustive agent (oxidant) are reagents of the reaction of redox; the ignition source is a source thatforms energy that is necessary to initiate the reaction (energy of activation).The necessary presence of fuel, combustive agent and primer at the same time is illustrated by the fire triangle (orcombustion triangle).Once the reaction is triggered, it emits heat that is absorbed by the layers of combustible mixture that warm up andreact with high velocity.In this way a reaction front is formed, often called flame front, that moves from the combusted mixture to the non-combusted mixture, provoking the ignition of the remaining combustible mixture.The speed with which the flame front moves is the propagation speed of combustion.The phenomenon “explosion” is verified when the energy released from the combustion and the propagation speedare too much elevated to be absorbed from the environment and in the consequence increases temperature in a shorttime and at little space that creates a pressure wave which spreads in the environment.Not all of the combustible-combustive mixtures, even if they are triggered, finish with an explosion.The conditions that determine if an atmosphere is explosive are physical/chemical characteristics of the fuel (explosiveproperties).Moreover, with the term “explosive atmosphere” it is intended a mixture characterized by:2. TECHNICAL ASPECTSFire triangle• flammable substances in the state of gas, vapour, fogor dusts and fiber with determined properties and indetermined concentrations in volume;• the air in atmospheric conditions;• as consequence of an ignition, the combustion spreads tothe mixture that is not burnt.The atmospheric conditions occur when the concentration ofoxygen in the air stands for approximately 21% and they includepressure and temperature variations over and under levels of1 atm and 20°C which do not influence much the explosiveproperties of substances.An atmosphere that is susceptible to transform to an explosiveatmosphere as a cause of local and/or operative conditions iscalled “potentially explosive atmosphere”.Also the ignition that is necessary to start the explosive reactionhas to have determined properties, indeed the energy of ignition,measured in Joule, has to be bigger than a determined value(minimum) threshold that differs for each combustible substance,below which does not originate any reaction.
  59. 59. 572.2 The areas at riskMany industrial processes require the use of inflammable or combustible substances that are stored, manipulated,transported and in the end utilized inside of the production process. Apart from the explosive substances or chemicallyinstable, for which there is a notable risk, there is a high number of substances that have in certain conditions acharacteristic to initiate an explosion.The substances that can originate explosive mixtures are utilized in numerous operations that take part of normalworking activities. For example in painting activities, flour milling, charging batteries, storage operations and transportof gas substances, etc.It results natural to consider the explosion risk in chemical and/or petrochemical work environments. Nevertheless, wehave to take into account that in many other activities (for example woodworking, mills, distilleries, etc.) the presence ofinflammable mixtures is also very probable and it should be evaluated and prevented. Many work activities that involvesubstances at risk, are integral part of normal activities inside of work environments that we can define as “ordinary”. Insuch work environments it is not automatic to think of the explosion risk.An extraordinary example is an accident that was registered in the end of 2011. In Shanghai in Pegatron, a subsidiaryof a company in Taipei that works for Apple, an explosion occurred with a result of 61 people injured. The cause of theexplosion was aluminium powder which is used to polish the cases for iPad. However more serious was an accidentthat occurred in May 2011 in a plant of Foxconn Technology, the biggest producer working for Apple. The 20th May inChengdu, in China the explosion of (combustible) aluminium powders caused the death of three workers and 15 otherswere injured. These episodes should lead us to the conclusion that the risk is high at work places where normally we donot expect the presence of the explosive atmosphere, which is a consequence of our underestimation of the possibilityof the formation of explosive mixtures.Consequences of an explosion in an area at risk
  60. 60. 582.3 Explosive atmosphere at presence of gas, vapour and fogThere are illustrated some properties of each inflammable substance that can originate an explosive atmosphere in formof gas or vapour mixed with the air. These properties are fundamental for the evaluation of the risk and for the choiceof electrical devices (classification of gas). - Limits of inflammabilityA substance in form of gas, vapour or fog that is mixed with the air, becomes an explosive atmosphere only if theconcentration of the same substance in the air is sufficient to make it inflammable. Air-fuel mixtures are inflammableonly at limited fuel concentrations in the air that are defined by inferior and superior limits.Graphical representation of inflammability limitsTwo limits represent the minimum and maximum fuel concentration thatallows the spread of flame. The concentration is usually expressed asa volume percentage.To determine the substance explosivity there are two limits defined: ‐ LEL (lower explosive level): gas or vapour inflammable concentrationin the air, under which the atmosphere is not explosive‐ UEL (upper explosive level): gas or inflammable vapour concentration,over which the atmosphere is not explosiveIn the table explosive limits of some gases and vapours are quoted; some of these fuels have explosive intervals thatare quite narrow; the others have an extended explosivity and can be considered “more dangerous”, as little emissionsform explosive atmosphere. In some cases the superior limit is so high that some substances represent an UEL equalto 100% as their vapours can explode practically with no need of air.Substance LEL% UEL% Substance LEL% UEL%hydrocarbons alcoholsMethane 5 15 Methyl alcohol 6,7 36Etane 3 12,4 Ethyl alcohol 3,3 19Propane 2,1 9,5 Butyl alcohol 1,7 12Butane 1,8 8,4 inorganicsEthylene 2,7 37 Ammonia 15 28Propylene 2,4 11 Hydrazyne 4,7 100Acetylene 2,5 100 Hydrogen 4,0 75Benzene 1,3 7,9 ketonesPentane 1,4 7,8 Acetone 2,6 31Hexane 1,2 7,4 Methyl ketone 1,9 10Examples of inflammability limits of some gases and vapours (atmospheric conditions) - Flash pointWhen the explosive atmosphere is generated by combustible liquids, for example inflammable liquid in an opencontainer, the characteristics of the combustible that expresses inflammable properties and of capacity to form explosiveatmospheres, is the temperature of inflammability.
  61. 61. 59The flash point is the lowest temperature at which at pressure of 760 mmHG vapours are formed in such amount thatin the presence of oxygen and of the ignition the phenomenon of combustion does occur.Here below there are some examples of inflammable liquid substances and the relative flash point.Substance Tinf [°C] Substance Tinf [°C]Petroleum -20 Ethylic ether -45Gas oil +55 Acetone -17Benzene -11 Ethyl acetate -4Ethyl alcohol +12 cyclohexane -20Examples of inflammability temperatures of some substancesThe flash point is an important property to ensure safety against explosions, as it is the basic parameter to evaluateif an inflammable liquid substance can form explosive atmosphere in a determined work environment with the properenvironmental temperature in which it is stored, managed, transported or produced. - The minimum energy of ignitionTo trigger the explosive atmosphere it is necessary to form quantity of energy called energy of ignition. This one changesaccording to the concentration of the combustible and tends to a minimum when it approaches the stoichiometricconcentration, called the minimum energy of ignition. The minimum energy of ignition is a specific characteristic of eachsubstance. Therefore in literature there are described curves of ignition for each inflammable substance.The energy of ignition increases notably with concentrations that correspond to inferior and superior limits ofinflammability.Ignition curves of hydrogen propaneThe graph illustrates the minimum energy of ignition of hydrogen that is considerably inferior: which means that thereis required less energy to trigger the explosive atmosphere of hydrogen compared with the explosive atmosphere ofpropane. - The temperature of ignition (autoignition)The temperature of autoignition is the lowest temperature at which the combustible-combustive mixture needs to bebrought, so it ignites itself automatically.LEL % UEL %IDROGENOLEL % UEL %LEL % UEL %1,0PROPANOIDROGENOLEL % UEL %innesco(mJ)Energia minima di innescoEnergiafiinnesco(0,1Energia minima di innescoEnergiaEnergia minima di innesco0 10 20 30 40 50 60 70 80 90 1000,01Energia minima di innesco0 10 20 30 40 50 60 70 80 90 100Concentrazione in volume (%)Ignitionenergy(mJ)Concentration in volume (%)PROPANEhydrogenMinimum ignition energyMinimum ignition energy
