Apparatus using protection concept flameproof enclosure 'd'; 10.1 Standards for flameproof apparatus; 10.2 Construction and testing requirements for flamepaths10.3 Construction of flameproof enclosures, entry facilities and component partsThe Health and Safety at Work Act, together with current and impending EU Directives, obliges those responsible for hazardous areas, those who work in such areas and those who supply equipment for use in such areas to demonstrate that they have taken all necessary and reasonable steps to prevent fires and explosions. This book addresses these issues, seeks to explain the ever increasing complexity of standards and codes pertaining to this field and describes their method of application and the application of other procedures to assist those involved.The only book which provExplosionproof electric apparatus and appliancesElectric apparatus and appliancesSafety measuresHazardous substancesSafety measuresExplosionproof electric apparatus and appliances.Electric apparatus and appliancesSafety measures.Hazardous substancesSafety measures.363.189621.31/042/0289 21621.310420289McMillan Alan1822851MiAaPQMiAaPQMiAaPQBOOK9911006834803321Electrical installations in hazardous areas4389266UNINA
