Based upon variance in the proportions of the four metals present, it is possible that engineering controls may reduce exposure such that a lead, cadmium, arsenic, and chromium project becomes just a lead project. Moving contaminants away from the workers. This method is crucial to abrasive blasting projects. Computer modelling may be used to design these containments. Onsite testing may be performed using foggers, anemometers, and manometers.
Localized capture includes the use of vacuum blasting and shrouded power tools.
However, localized capture controls allow effectiveness to be adversely affected by the worker's technique. This should be considered when using these methods. Wet methods may be the best selection as an engineering control in specific situations. Wet methods involve the use of moisture to reduce dust generation. Corrosion inhibitors are available to reduce the corrosion which may be caused through the contact of newly bared steel and water.
