When working with hazardous materials, like during a lead-based paint removal project, workers on the site can be exposed to a multitude of dangerous substances. These hazardous substances can settle onto clothing and other equipment then be transferred to the workers skin as they leave the site.
Decontamination allows for the worker to remove contaminated clothing and wash thoroughly before exiting, lowering the chance of the worker and their family becoming sick or ill after they have finished working for the day.
Projects that include the removal of Lead based paints, or when working with toxic chemicals (refer to Safety Datasheets [SDS] supplied with chemicals to be aware potential risks) that can potential be absorbed through the respiratory and digestive system. It is then critical to remove any contaminated clothes and wash immediately after existing the exposed work area. This is highly important especially before consuming any food or water.
