| Résumé : |
Chemicals are subject to a growing number of regulations pertaining to their industrial operations such as the transport of goods and consumer usage. Many of the regulations applicable to pigment dry colors are based not on the pigments per se, but on heavy metals or other inorganic components used in their manufacture.
Pigments serve many beneficial functions in modern society and technology. Irrespective of their end use, they are not considered consumer chemicals, but are primarily directed to a variety of industries. They are processed into products such as paints, printing inks and platics, which are then directed to other industries and then on to their respective consumer markets.
Industry has the responsibility to be informed ot the potential hazards associated with the raw materials, so that suitable measures may be taken to insure the safety of employees, customers, the public, and the environment. In this article, safety and health information for pigments is discussed briefly.
It is presumed that the pigment is a dry powder without surface treatment. No attention has been paid to the risk potential of vehicles, solvents, and other materials used in the preparation of various pigment grades. With appropriate handling procedures, engineering controls and personal hyigienic practices, no pigment any grade should pose a health risk to the industrial worker.
Under normal circumstances, pigment dry colors are nonflammable and unreactive chemicals. It is important, however, to appreciate that there are certain abnormal circumstances associated with the storage and/or use of pigment products, under which hazardous situations may occur. There are three such circumstances : excessiveheat, dust explosion, and chemical reactivity. |
