Implementing the Combustible Dust Hazard Assessment Flow chart. For process equipment, this is straightforward. Does a sufficient amount of combustible dust exist to cause enclosure rupture if suspended and ignited? Is a means of suspending the dust present? If the answer to both is yes, the equipment presents a dust explosion hazard and should be included in the PHA. Read more

Regarding vessels and tubes containing combustible gases or dusts, it is important to acquire knowledge on the conditions under which a fuel and oxidizer could undergo explosive reactions. These conditions are strongly dependent on the pressure and temperature. Given a premixed fuel-oxidizer system at room temperature and ambient pressure, the mixture is essentially unreactive. However, if an ignition source is applied locally and the composition of the mixture is within certain limits (the so-called flammability limits), a region of explosive reaction can propagate through the gaseous mixture due to mainly two phenomena.

Inhibitors are chemical substances that are used in small amounts to suppress the polymerization reaction of a monomer. An inhibitor has to be completely consumed before a polymerization reaction can proceed at normal rates. The time required to completely consume the inhibitor is often referred to as an “induction” time. Inhibitors react with polymerization initiation radicals to produce products that cannot induce further reaction. Read more

Explosions can occur in vessels or enclosures containing flammable gases and/or dusts. Explosion venting, often referred to as deflagration venting (because we cannot practically vent detonations), is used to protect from catastrophic vessel/enclosure fai Read more
