RC28 Recommendations for Spark dectection and suppressions on pneumatic conveying

Pneumatic conveying systems are employed in many process industries where there are various possible sources of ignition and the consequent risk of a fire or dust explosion. The principal hazard arises from the pneumatic conveyance of materials from one area to another, on some occasions through fire compartment walls. Thus a source of ignition in one area has the ability to cause a fire in another, remote area. These recommendations outline the safety considerations for fire detection and suppression systems used in such applications.
