Inspection, maintenance and repair of explosion protected equipment

Inspection, maintenance and repair of explosion protected equipment

These procedures shall be done -and this is a general rule - by qualified personnel, who are experienced in the various types of explosion protection, installation practices and rules and the principles of area classification. 

After installation of an explosion protected apparatus and before it is brought into service, it shall be given an initial inspection. During service, regular periodic inspections or continuous supervision shall guarantee the safe operation of the apparatus or system. If necessary, maintenance or repair shall be carried out. The standards define different grades of inspection
