Conveyor belts are used for a long period of time in the industry branches where potentially explosive atmospheres could occur. The use of conveyor belts in industrial spaces with danger of explosive atmospheres, implies fulfilling by these of certain safety requirements, in order to prevent the ignition sources of explosive atmospheres. The need to provide the highest level of protection in the industrial spaces with danger of explosive atmospheres led, on the one hand, to the use of conveyor belts with adequate ...

Non-electrical equipment has been used for over 150 years in industries in which likely to occur a potentially explosive atmospheres and a great deal of experience has been gained in the application of protective measures for reducing the risk of ignition of such atmospheres to an acceptably safety level. For using non-electrical equipment in potentially explosive atmospheres, it became necessary to produce ignition protection concept standards which clearly defined these protective measures and incorporated the e...
