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 prov 606 $aExplosionproof electric apparatus and appliances 606 $aElectric apparatus and appliances$xSafety measures 606 $aHazardous substances$xSafety measures 615 0$aExplosionproof electric apparatus and appliances. 615 0$aElectric apparatus and appliances$xSafety measures. 615 0$aHazardous substances$xSafety measures. 676 $a363.189 676 $a621.31/042/0289 21 676 $a621.310420289 700 $aMcMillan$b Alan$01822851 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9911006834803321 996 $aElectrical installations in hazardous areas$94389266 997 $aUNINA
