Work conditions in painting, sandblasting and restoration can vary depending on the job site. They can be in confined spaces or out in the open air. Either way, the workspace and environment must be protected with the proper ducting to handle not only contaminated air but also the fresh air that may be needed to be supplied to the work area as well.
In painting applications, the concern is paint-mist particles. Sandblasting applications have a risk of airborne dust and dry particulates. Restoration work can release dust and/or hazardous materials, such as asbestos and lead, from the structure being restored.
