Fire is one of the major hazards in the oil & gas sector. A fire can ignite during the production process even if all precautions have been taken. It can also start in other areas like accommodations or the galleys. Uncontrolled fire, smoke and gas are extremely dangerous and the progression must be contained and stopped as soon as possible. Fire and gas dampers installed in HVAC ducts have a significant role in preventing the progression of fire, smoke and gases that can become life threatening. A fusible link inside the ATEX certified fire damper also operates as a fire detector. As smoke and other toxic gases can be more dangerous than the fire itself, it is important that the chosen fire damper also prevents smoke from spreading.
