An important component of effective hazardous material management is creating and maintaining a site drawing or floor plan of a facility on which hazardous material locations are identified through use of color-coded symbols. Each hazardous material assessment we conduct includes technical drawings to ensure that visitors to a facility have floor plan drawings to quickly determine the locations of any hazardous materials on the premises. The drawings are also used during hazardous material repair and/or removal to provide quick and accurate visual information.
