Aspects regarding the explosion risk assessment of installations in atmospheres with combustible dust

Many industrial processes involving the presence of dust and combustible dust, suspended or accumulated in form deposits, have potential to lead a fire, explosion decomposition oxygen. As damage caused by an is generally greater than that explosions flammable gases vapours, special attention must be paid measures means protection prevention dust. A can only occur if there mainly potentially explosive atmosphere generated air / mixture source ignition. The level safety given operational efficiency employees technical equipment involved production process ensure at least one above conditions eliminated. probability related physicochemical properties processed materials, together with nature operations performed used. This paper highlights principles factors taken into account when conducting risk assessment installations atmospheres order establish measures, aim ensuring tolerable risk.
