Shenhai plahvatuskindel
A-klassi seadmed, mis on ette nähtud tolmu plahvatuspiirkonna jaoks 21 iseloomustab maksimaalne pinnatemperatuur TA 85°C. Keskkondades, kus tuleb vältida plahvatusi, õhk võib sisaldada kergestisüttivaid ja plahvatusohtlikke materjale, näiteks gaase, aurud, tolm, ja kiudaineid. Explosions can occur when these substances come into contact with sparks, flames, certain temperatures, or specific air pressures. It is therefore critical to take measures to prevent such explosions.

| An explosive environment in the air that continuously appears in the form of combustible dust clouds, exists for a long time or frequently. | Places where explosive environments in the air may appear or occasionally appear in the form of combustible dust clouds during normal operation. | In the normal operation process, an explosive environment in the air in the form of combustible dust clouds is impossible to occur in places where the instrument exists for a short period of time. |
This highlights the importance of adhering to strict safety standards, especially in industrial environments where plahvatusohtlik materials are present. The use of Class A devices, with their specified maximum surface temperatuuri, is a key strategy in mitigating the risk of explosions. These devices are designed to operate safely within explosive atmospheres by limiting their surface temperatures below the ignition temperatures of the surrounding tuleohtlik materjalid.
The implementation of such safety protocols ensures that operations in hazardous areas remain secure and explosion-free, thereby protecting both personnel and infrastructure.
