This Question of the Day, concerns electrical equipment possibly to be installed in an explosive store. The question has been answered by SELECT (Theme - Fire & Safety):
Question: Can we install lighting switch and fire alarm devices inside an explosive store, or should we install this equipment outside?
Answer: Equipment in these areas needs to be suitable for installation in the hazardous zones. If it has not been specifically designed for use in hazardous areas, then the equipment should be installed outside the location.
Voltimum Managing Editor James Hunt says: 'Areas where such combinations are found, or are likely to be found, are called 'Hazardous Areas'. Hazardous areas are defined in The Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR) as 'any place in which an explosive atmosphere may occur in quantities such as to require special precautions to protect the safety of workers'. In this context, 'special precautions' is best taken as relating to the construction, installation and use of apparatus, as given in BS EN 60079 -10.
