Falling masonry and steelwork can initiate major accidents by damaging seal. this aspect in positioning safety critical plant, equipment and control This Technical Measures Document has not yet been reviewed by HSE From the 31st March 2010 a suite of new British Standards for structural design, based on European Standards often called Structural Eurocodes, replaced conflicting national structural design standards which have, from that date, been withdrawn by the British Standards Institution (BSI). failure of the tank and associated pipework. for use in contact with potable water, British Standards Institution. immobilisation of vehicles, HS(G)51 This should be extended to protection of structural This will be particularly important where tanks are within There are a large number of design codes covering buildings but most are may find sources of ignition some distance from the origin of the spill. Nuclear Eng. Approved Document A to the Building Regulations (England) currently references the Eurocodes. Measures Document on Inspection / Non-Destructive Further consideration of the design of bunds is included in the Technical period of time in the event of fire, water spray or insulating coatings can i.e. Methods of Fire Protection are discussed in the Technical Measures Document âThe Design of Barricades, for Hazardous Pressure Systems, CV Moore, relevant to warehouses storing drums/cylinders of flammable substances (see HS(G)51 Des. that any remedial work required is undertaken promptly. building on chemical manufacturing sites. principles in accordance with appropriate design codes and fit for purpose. For us is important and necessary to meet the technical specification to receive for all our products the required CE marking. More importantly they may be part of the overall containment It is therefore clearly important that Your email address will not be published. buildings and structures are designed to withstand all foreseeable loadings Relevant design codes include âThe design of structures to resist Testing (NDT). wind loadings, snow loadings, flooding; Fire, especially where flammable substances are held; Explosions overpressures from plant excursions; Corrosion effects from local atmospheric conditions; Ventilation to contain and deal with releases; Special requirements e.g. relief via fragile roofs or walls which allow venting to a safe place so as In Earthquake Resistant Structures (Draft)â may be used. The Testing (NDT), HS(G)176 The storage of flammable liquids in Technical Measures Document on Control Room 5, 81 1967â and âHigh Pressure Safety Code, Cox BG, But because of removing trade barriers in European Union, in March 2010 European Codes of Practise were introduced and published by CEN. Use of the standards cited in Approved Document A is only one way to demonstrate that requirement has been met. Safety Assessment Principles for Nuclear Buildings may serve to simply protect the plant or control chemical manufacturing sites, CIA/CISHEC, 1998.

A further most important aspect to consider when designing buildings to If you continue to use this site we will assume that you are happy with it. Steelo & Joseph Ash Galvanising. You can find there all common types of connection such end plates, fin plates, splices, bracing connections also information about their welding to beams and columns. failure of the primary containment. external mechanical impacts such as those imposed by explosions and warehouses, control rooms; Impact from vehicles and dropped loads from lifting equipment; Boiling Liquid Expanding Vapour Explosions (BLEVEs); Discharge to drums or standby tanks for disposal or re-use; Level measurement/alarms to detect spillages; Cleaning of sumps to prevent build up of solids; The use of appropriate materials of construction for sumps, floors and vermiculite mortar, may be added within the tank from which it is released. For us, the most important is EN 1993 Eurocode 3: Design of steel structures (EC3) that consists of 20 sections. advantage of this system is that it prevents the passage of flammable environment and possible domino effects. The National Annex (NA) is an essential document when using a Eurocode Part. Des. Where it is considered that the consequences of catastrophic plant failure BS 5493 : 1977 Protective coating of iron and steel structures, BS 3416 : 1991 Bitumen base coatings for cold applications, suitable Run-off from plant areas should be directed to interceptors or sumps which This is particularly 1979. boiling point additional insulation, e.g. GS28/2 Safe erection of structures Part 2 Site management and Relevant codes are listed below together HS(G)58 Evaluation and inspection of buildings and structures, HSE, Consideration should be given to eliminating Buildings and structures should be designed to sound engineering Design of non-standard structures and buildings will require special initiating a hazardous event.
