Hydrogen is a promising energy carrier for future low-carbon systems, but its high flammability, wide explosion range, and low ignition energy present significant safety challenges. This paper proposes an integrated ATEX-based risk assessment methodology specifically designed for hydrogen storage and utilization systems. The methodology combines regulatory requirements, including EN 1127-1:2019, with a hydrogen-specific risk matrix, ATEX zone classification, and operational risk mitigation measures. A high-pressur...

The flameproof enclosure type of protection is a safety method designed to prevent the ignition of an explosive atmosphere in hazardous environments. It involves enclosing components that may generate sparks, electrical arcs, or high temperatures within a robust, explosion-resistant housing. This enclosure is engineered to withstand the pressure generated by an internal explosion of a flammable gas mixture, ensuring that the explosion does not propagate to the surrounding atmosphere. This type of protection is par...

Electrical installations in spaces classified as being in danger of explosive atmospheres have special characteristics to correspond to operation in such atmospheres. For safety reasons in these areas, it is essential that during the lifetime of these installations, the integrity of these special characteristics be maintained. The assessment of explosion-protected electrical equipment within the scope of certification is of paramount importance in view of the risk of explosion which must be minimized to ensure the...

Electrical equipment that operates in a potentially explosive atmosphere, have characteristics specially designed for operation in this area. For security reasons, it is essential that the integrity of these special features be preserved in these areas throughout the life of the installation. Using electric equipment in potentially explosive atmospheres brings forward several particularities therefore the problems that appear during the design, construction and operation of electrical devices and installations bri...

The use of electrical equipment in potentially explosive atmospheres requires special attention, namely from the point of view of their construction and maintenance. Together with the technological developments, these objectives can easily be met, objectives which are defined by European standards concerning the construction, use and maintenance of explosive proof equipment. Evaluation of explosion-proof protected electrical equipment in scope of certification is extremely important considering the risk of explosi...

The paper aims to address the importance of inspection and maintenance of electrical equipment used in liquefied petroleum gas car filling stations. In order to maintain in operation the electrical equipment in environments with potentially explosive atmospheres under harsh conditions, the personnel involved in inspection and maintenance activities must be trained in such a way as to know the operation of these electrical equipment with different types of protection and how to perform their maintenance. Inspection...

The evaluation of explosion-proof electrical equipment for certification is particularly important given the risk of explosion and must be minimized. This in order to ensure the safety of life, health of workers, to prevent damage to goods and the environment when they meet the essential security requirements at European level. Directive 2014/34 / EU states that equipment used in explosive atmospheres must be designed to operate without endangering the environment for which it is intended. This paper deals with th...
