EQUIPMENT DESIGN AND CONSTRUCTION There are a number of methods of protecting electrical equipment, which prevent an explosion when used in a flammable gas atmosphere, in the presence of combustible dust or easily ignited fibers. Three elements are required for an explosion to occur fuel, oxygen and a heat or ignition source must be present.
A dust explosion is the rapid combustion of fine particles suspended in the air within an enclosed location. Dust explosions can occur where any dispersed powdered combustible material is present in high-enough concentrations in the atmosphere or other oxidizing gaseous medium, such as pure oxygen.
how to design a safe dust collection system. It is regarded as the guiding dust document and the most general on the topic, and it will lead you to other relevant documents. Depending on the nature and severity of the hazard, NFPA 654 will guide you to the appropriate standard(s) for explosion venting and/ or explosion prevention, as follows
methane or coal dust in mines, or petrol and in future perhaps hydrogen in vehicles. In such cases protection and safety are provided by equipment which is reliably explosion proof. These days, the construction of explosion proof equipment goes far beyond the fi eld of electrical engineering. As will be demonstrated in the further descriptions,

explosion prevention consists of avoiding sources of ignition. Manufacturers of devices and protection systems must therefore develop and design their devices and systems so that they present no source of ignition neither in normal opperation nor in consideration of foreseeable faults. Design-based explosion prevention limits the effects
This shock is often caused by a relatively mild primary explosion inside the plant, the flame from which serves as a means of ignition for the dust cloud formed in the workroom. This secondary explosion disperses more of the dust accumulated in the workroom and ignites these clouds until the whole building is swept by the explosions.
Explosion Suppression Systems How Chemical Isolation Prevents Propagation. Chemical suppression systems are only as good as the speed at which they activate to protect the vessel and interconnected equipment. Fike’s chemical suppression systems activate in the blink of an eye to suppress the initial explosion and prevent secondary explosions.
