Cargo tank cleaning; A static charge will be produced when water … Injecting steam into a cargo tank during tank cleaning can cause a build up of static within the condensed water droplets. Forced air gas freeing devices can cause a static charge to build up on the body of the equipment. A static charge will be produced when water is forced, under high pressure, through the nozzle of a tank cleaning machine. Electrostatic phenomena arise from the forces that electric charges exert on each other. Chapter 11 (Shipboard Operations). Here is an example of bonding wire from Justrite. Anti-static materials inhibit tribocharging by preventing the buildup of static electricity. Static electricity presents a fire, as well as an explosion hazard on a … Industry specifications provided to us by Newport warn that the inherently unstable compound “can detonate” in the presence of static electricity. The buildup of static charges generated by machinery can cause sparking, which may ignite combustible gasses or liquids with disastrous effects to personnel and equipment.
