These protection methods are engineered solutions to either remove one of the parameters required for an explosion or in the case of Ex d flameproof contain any explosion to prevent it propagating Understanding ATEX equipment protection concepts. October 27, 2013 By Stuart Harvey. Control panels built for use in hazardous areas have to be designed to meet the specific risks of the installation site. Panel builders need both a sound understanding of the safety principles and expertise based on broad experience. Category 3, specified as requiring a normal level of protection with a small chance of an explosive mix forming (Zone 2). Table 3 - Protection Concepts Protection concepts refer to the means of ensuring a piece of equipment being used in a hazardous area does not cause an explosion.
