Sealing Cable Entries: When cables go into the tray, we use special explosion-proof fittings (called cable glands) that have Ex certifications. We also fill the holes with fireproof putty (it needs an oxygen index of at least 32%). Chemical plants have risks like explosive gases, dusts, or vapors. It's serious business – around 15% of chemical plant explosions happen because of. Cable Trays have been permitted in the hazardous (classified) locations in the National Electrical Code for Class I (flammable vapor and gases) since the 1978 NEC and have been used extensively in chemical plants, refineries, and other types of facilities. Not only do we sell these cables, we also understand the application of them. For ATEX or IEC applications we offer instrumentation, control and power cables to BS/EN 50228-7, NEK 606, BS 6883, BS 5308, BS 5467 and many other. Abstract – This paper explores the various standards and requirements for the certification, selection, use, and installation of cables and cable glands used in explosive gas atmospheres throughout the world. This has the potential of making a minor mishap a major explosion.
