Personnel responsible for operating equipment and processes in explosive environments should provide all personnel working on site with information and materials on the safe use of hand tools. The following two different types of tools should be distinguished: (1) Tools that can only cause a single spark when in use (such as screwdrivers, wrenches, impact screwdrivers); (2) Tools that produce a cluster of sparks during cutting or grinding processes. In Zone 0 and Zone 20, tools that can cause sparks are not allowed to be used. In Zone 1 and Zone 2, steel tools are only permitted when they meet the requirements of item (1). If it can be ensured

Ambient temperature refers to the temperature of the air or other medium surrounding the equipment or component. Under normal circumstances, the ambient temperature for equipment operation should be -20 to 40 ℃. In such cases, no additional ambient temperature marking is required. However, when the equipment is expected to be used in an environment outside this temperature range, it is considered a special situation. The marking should include the symbol Ta or Tamb along with the upper and lower limits of the ambient temperature. If this is not feasible, the symbol “X” should indicate the special operating conditions including the upper and lower limits of the ambient temperature. This means

In the operation of enterprises, warehouse management plays a very important role and is the cornerstone of ensuring the continuous stability of product quality. Once problems occur, it will directly cause economic losses and even bring adverse effects to the brand. Now let’s talk about those things in warehouse management that cannot be ignored. The warehouse should have appropriate warehouse management systems and be staffed with professional personnel. Stored items should be classified and placed on shelves. For small parts, storage boxes can be added to the shelves. Labels should be used to identify the model and quantity of each item for easy management and query. Regular inspections of stored

It is well known that the protective performance of the equipment enclosure protected by the dust-proof ignition-proof enclosure “t” is a key point that product design focuses on. Therefore, the structural rationality of the gaskets and seals that play a protective role is particularly important. I. Structural Requirements In the mating surfaces, compressed gaskets can be used to ensure the effectiveness of the enclosure seal. All gaskets and seals should be of an integral continuous structure, that is, annular and uninterrupted. The structure of the enclosure should ensure the correct position of the gaskets. If the protection degree of the enclosure depends on the gasket at the enclosure joint and

The encapsulated type involves completely enclosing the components that may generate sparks or heat capable of igniting explosive mixtures within a compound or a non-metallic casing with adhesive bonding, ensuring that they cannot ignite dust layers or explosive environments under operating or installation conditions. The above is the definition of potting type. In simple terms, it means to enclose the possible ignition sources so that they do not have the ability to ignite under normal operation and fault conditions. Common enclosure processes include die-casting and casting. For equipment protected by potting type “m”, the compound, potting structure, equipment temperature, testing and marking need to be considered. 1. Consider the manufacturer
