Keeping Lead at Work

by Greg M. Piacitelli and Elizabeth A. Whelan, PhD

Exposure to lead from construction work may not be limited to the job site. Workers can inadvertently carry lead home from work on clothes, skin, hair, and tools, and in their vehicles. These “para-occupational” or “takehome” exposures among workers’ families may cause lead poisoning in family membe...

Trouble with Paint: Hygroscopic Stresses

by Clive H. Hare

Water is one of the primary agencies of paint film deterioration (Fig. 1). Rain, snow, ice, dew, and even just humidity, in combination with oxygen and ultraviolet (UV) light, all contribute to the gradual breakdown of the coating film. They wear away the film; they degrade its form and appearance; ...

Inorganic Zinc Rich

by Harlan H. Kline

Inorganic zinc coatings contain metallic zinc dust in an inorganic binder. The binder in the cured film is a silicate. This class of coating is different because it protects the substrate by galvanic action. When 2 metals of different electrochemical potential are in contact, the more active (i.e., ...
