Equipment in this category is intended for use in areas in which explosive atmospheres caused by mixtures of air and gases, vapours or mists or by air/dusts mixtures are present continuously, for long periods or frequently. Equipment of this category ensures the requisite level of protection, even in the event of rare malfunctions relating to equipment, and is characterised by means of protection such that:  either, in the event of failure of one means of protection, at least an independent second means provides the requisite level of protection,  or the requisite level of protection is assured in the event of two faults occurring independently of each other 3.15.2 equipment Group II category 2 equipment designed to be capable of functioning in conformity with the operational parameters established by the manufacturer and ensuring a high level of protection. Equipment in this category is intended for use in areas in which explosive atmospheres caused by mixtures of air and gases, vapours or mists or by air/dusts mixtures are likely to occur. The means of protection relating to equipment in this category ensures the requisite level of protection, even in the event of frequently occurring disturbances or equipment faults that normally have to be taken into account 3.15.3 equipment Group II category 3 equipment designed to be capable of functioning in conformity with the operational parameters established by the manufacturer and ensuring a normal level of protection. Equipment in this category is intended for use in areas in which explosive atmospheres caused by mixtures of air and gases, vapours or mists or by air/dusts mixtures are unlikely to occur or, if they do occur, are likely to do so only infrequently and for a short period only. Equipment of this category ensures the requisite level of protection during normal operation 3.16 chemical reaction process where the coating material or any part of the coating material reacts with the materials of construction of the machine and/or process which takes place between the components of coating materials SIST EN 12621:2006+A1:2010

The following hazards may occur when installing, operating, cleaning or maintaining the machine. NOTE Information on the method of risk analysis is given in EN 1050. 4.2 Mechanical hazards 4.2.1 Crushing, drawing in or trapping, impact hazards: These hazards are related to:  physical contact with fixed or moving parts of the machine;  instability of mobile machines (causing tipping or moving).
