jacent stand.6.2 Ground loadsThe maximum ground load (workingload) is 50 kN (= 5000 kilogramweight = 5 t) per square metre, exceptfoyers. Permissible point loading= max. 70 kN acting on an areaof 10 x 10 cm.The permissible load on the foyerfloors is 5 kN/m². In the area of directaccess to the halls, a maximumground load of 30 kN/m² ispermitted.The permissible ground load in hall4.1 is 5 kN/m².6.3 Loading of walls & ceilingsIt is not permissible to secure standstructures to parts of the hall ceilingsor walls. This also applies toattachments to prevent stand structuresfrom toppling. Stand constructionmaterial may not beleaned against outside walls anddoors, because these partially consistof glass or acoustic material.Exceptional permission for the suspensionof items from ceilingsshould be applied for throughMESSE BREMEN's TechnicalManagement, who will thenarrange for preparation of the suspension,if appropriate. The attachingof decorations or suchlike tosprinkler pipes, water pipes, ventilationpipes or other installations orobjects that form part of the halls isprohibited.6.4 Stand and exhibit safetyThe exhibitor is responsible for thestability and safety of all standstructures and exhibits; proof of thismay be required.For the construction of stands, onlyapproved materials may be used.Load-carrying parts must havebeen checked, and such checksmust be certified (structural calculations).This applies especially totwo-storey exhibition stands. Thesemust in all cases be approved bythe Bremen Building RegulationsAuthority (the BOA). Constructionmaterials and components for theconstruction of stands must benon-flammable or flame resistant.DIN 4102 B1 shall apply as a basis.Construction materials which arehighly flammable or which dripwhen burning are not permissible.Decorative materials must be nonflammable.On request, appropriateevidence must be provided by thestand operator.Flower arrangements with leafy orpine twigs, trees or similar may notbe used.Materials which burn explosively(such as bamboo, hay, straw orpeat) are not permissible.6.4.1 Stand ceilingsSprinkler systems are installed inhall 4.01, 4.1 and in the foyers ofhall 4 to 6. In these halls, every singlesquare metre of every standceiling must be open to an extent ofat least 75 %, in order to allowTECHNISCHE RICHTLINIEN TECHNICAL GUIDELINES | TECHNICAL GUIDELINESsprinkler water to pass verticallythrough the ceiling. Otherwise, astand sprinkler system must be installedfor surfaces situated underneath;such cases must becoordinated with MESSE BRE-MEN's Technical Management.Textile ceilings (mesh size of atleast 2 x 4 mm) suitable for use withsprinklers are permitted, providedthat the span does not exceed5.00 m.No heat source of any kind is permittedin the vicinity of the sprinklernozzles, as these are activated at atemperature of about 68 °C, i.e.they then automatically spray waterinto the hall.The exhibitor will be held liable forany damage that occurs.Construction material for stand ceilingsmust be non-flammable.6.4.2 Access to technicalfacilities of the hallsHand-held fire extinguishers, firedetectors, pushbutton alarms, wallmountedhydrants, smoke flap actuatorsand the associated warningnotices must at all times be accessibleand visible. The functioning offire protection gates and fire doorsmust not be restricted by installationsof any kind, such as electriccables. It must also be ensured thatconnection points for the stand'selectrical supply, as well as distributioncabinets and telephone distributors,remain accessible.Access to the safety equipmentand technical facilities must begranted at any time to the personsappointed by MESSE BREMEN'sTechnical Management.6.4.3 Hall floorsIt is not permissible to put anchorsinto the hall floors and foyers, or todrill holes for pegs. The same appliesto other kinds of attachment,such as screws or nails. The companyrenting the stand is liable forany damage done. Double-sidedadhesive tape can be used to securecarpeting. It must be completelyremoved after the stand hasbeen dismantled. Sticking the entireunderside of floor coverings tothe floor (including the use of selfadhesivetiles) is not allowed.6.4.4 Safety lightingAdditional safety lighting must befitted in those stands in which thegenerally available safety lighting isineffective because of the stand design.This additional safety lightingmust be installed in such a way asto ensure that persons will easilyfind their way to the main rescueroutes in the hall (refer also to VDE0108).If an exhibitor requires continuousvoltage for accumulator-powered illuminatedpictograms, MESSEBREMEN's Technical Managementmust be consulted beforehand.6.4.5 Electrical safetymeasuresRegulation VDE 0100, Part 410,must be adhered to as a protectionagainst the dangers of indirect electricalcontact. Excess current protection(earthing) must be providedin stand installations.Fault-current protective devicesmust be installed (as of 1st January1993). Electrical sockets up to 16 Amust be protected by devices witha nominal fault current of 30 mA,and other sockets by devices witha maximum fault current of 500 mA.The conductor cores for power andlighting circuits must each have aminimum cross-sectional area of1.5 mm² (see also VDE 0108).6.4.6 VDE and EU low-voltageregulationsAll electrical equipment must conformto the VDE regulations or theEU low-voltage regulations andmust display an EU-recognizedsafety symbol.6.4.7 BalloonsIt is permissible to use balloonsfilled with non-flammable gas. Inclosed rooms or exhibition stands,the ratio relative to the volume of airin the room must be sufficiently low(otherwise there is a danger of suffocation).6.4.8 GlassOnly safety glass may be used.Edges of panes of glass must befinished or protected so as to preventany risk of injury. Structuresmade completely of glass must bemarked at eye level.Plexiglas must be fitted in a metalframe (for fire safety).6.4.9 Stand heatersThe operation of mobile heatingsystems fuelled by gas or liquid isnot permitted. Electrically poweredheaters are permissible, providedthat they conform to the generalstandards and safety regulations.Units with exposed heating wiresare not permissible. The units mustbe installed in such a way that anadequate distance from objects isensured. The unit must be switchedoff when the exhibition stand is vacated.6.4.10 Laser systemsLaser systems exhibited and thoseoperated for demonstration purposesmust fulfil the requirementsof the accident prevention regulationrelating to laser radiation (VBG93). The operation of laser systemsof classes 3 B or 4 must be reportedto the GewerbeaufsichtsamtBremen (the Trade SupervisoryBoard of Bremen).6.4.11 Welding workWelding work on the exhibitor'sown materials is permissible onlyby consultation and agreement withMESSE BREMEN's TechnicalManagement. If the parts to bewelded can be moved into the openair, welding inside the hall is notpermissible. In all cases, it must beensured that no danger can occuras a result of flying sparks. A fireguard (fire safety officer) and fireextinguishers must be provided. Inthe case of welding work, particularattention must be paid to the regulationsof GUV 26.21.6.4.12 CateringWhere roasting, grilling or deep-fryingequipment is used, the regulationsmay require the installation ofa vapour extractor if excessiveodour nuisance or activation of afire alarm can be expected to occur.6.4.13 Gas equipmentThe introduction of liquefied gas -such as propane, butane or suchlike- and its installation and utilizationare prohibited (see alsoSection 10.2). If this rule is contravened,MESSE BREMEN's Techn.Management is entitled to removethe units at the expense of the exhibitorand, if applicable, to havethe stand closed for safety reasons.If the presentation of goods on thestand is dependent upon the use ofliquefied gas, the use of gas maybe permissible after consultationwith MESSE BREMEN's TechnicalManagement, possibly subject tocompliance with particular safetyregulations and by agreement withthe Bauordnungsamt Bremen (theBremen Building Regulations Authority)and the Bremen FireBrigade.7 Sand, soil, gravelIf highly dirt-producing materialssuch as sand, soil or gravel areused, it must be ensured that damageto the floor and walls isavoided. If necessary, the floormust be protected by an underlaymade of suitable materials (e.g.plastic sheeting). In all cases, contaminationof the supply ducts mustbe prevented. The introduction andremoval of these materials must beperformed by means of suitableequipment designed such thatdamage to the floor cannot occur.Agricultural machinery may beused only if permission is obtainedfrom MESSE BREMEN's TechnicalManagement. Tracklaying vehiclesare impermissible in all cases.8 AnimalsIf animals are kept in the halls, itmust be ensured that damage - especiallyto the floor, walls and pillars- does not occur. The pens must beset up at a sufficient distance fromthe walls and pillars. In the case oflarge animals, the floor must beprotected by means of suitable materials.The event organizer or theexhibitor is responsible for keepingthe animals in a manner appropriateto the type of animal concerned,and for keeping the pens(halls) clean. Animal excrementmust not be allowed to pass directlyonto the hall floor or into the supplyducts.9 Supply of services tothe stands9.1 GeneralF 78
