Combatting Combustible Dust--Dust explosions in casting facilities can be devastating, and metalcasters must be vigilant to recognize and properly evaluate their risk

摘要

Ordinary materials that are normally nonhazardous may become hazardous when finely divided. Combustible materials, including resins, binders and certain metals, may pose an explosion risk in a metalcasting facility under some conditions. For example, phenolic resins that are manufactured onsite may contain ingredients that can condense and form a layer of combustible dust. On the other hand, sand that is pre-coated with phenolic resin does not present a problem. Combustible metals (e.g. aluminum, magnesium and titanium) must be handled with care to avoid accumulations of fine particles.
