Grace Environmental will conduct visual inspections, sampling, and laboratory analysis to determine the presence of asbestos in building materials. Inspections are conducted by a Division of Occupational Safety and Health (DOSH) Certified Site Surveillance Technicians (CSST) or Asbestos Consultants (CAC) using EPA protocols to comply with all federal Asbestos and Local Air Pollution Control District regulations. Asbestos clearance inspections are to ensure that removal was performed properly and de-contamination is complete. Final air samples are taken to measure fiber concentrations in occupied spaces.
