Class A equipment designated for Dust Explosion Zone 21 is characterized by a maximum surface temperature of TA 85°C. In environments where explosions must be prevented, the air can contain flammable and explosive materials such as gases, vapors, dust, and fibers. 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.
| Zona 20 | Zona 21 | Zona 22 |

| Lingkungan eksplosif di udara yang terus menerus muncul dalam bentuk awan debu yang mudah terbakar, terjadi dalam waktu yang lama atau sering. | Tempat-tempat di mana lingkungan yang mudah meledak di udara dapat muncul atau sesekali muncul dalam bentuk awan debu yang mudah terbakar selama pengoperasian normal. | Dalam proses operasi normal, lingkungan eksplosif di udara dalam bentuk awan debu yang mudah terbakar tidak mungkin terjadi di tempat-tempat di mana instrumen berada dalam waktu singkat. |
This highlights the importance of adhering to strict safety standards, especially in industrial environments where bahan peledak materials are present. The use of Class A devices, with their specified maximum surface suhu, 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 mudah terbakar materials.
The implementation of such safety protocols ensures that operations in hazardous areas remain secure and explosion-free, thereby protecting both personnel and infrastructure.
