Lead TestingGot peeling or flaking paint? About to renovate a Victorian or pre-1980 building?
Lead Inspections include paint and material sampling to identify existing lead hazards. Depending on the situation a lead inspection may involve sampling for lead in air, dust, soil and water. We also perform lead-paint inspections and lead risk assessments.
Lead Air Sampling
We provide air sampling services when testing for lead in ambient air. In addition to preliminary worker exposure evaluations, air sampling is useful at the end of abatement, renovation, or repair projects as part of a final inspection (“lead clearance”) of the abatement.
Air sampling for lead will not tell whether there is lead-based paint or other building materials that contain lead. Only physical (destructive) sampling of the material itself and analysis by an accredited laboratory can provide that answer. Air sampling may be useful if there is general concern about lead in the air or a suspicion that lead removal work was performed improperly.
Lead Dust Testing
Another type of sampling involves surface wipe methods. This can help determine background levels, ID possible contamination, or be utilized for clearance purposes at the end of an abatement, renovation, or repair project as part of a final inspection of the abatement or impact work. Since hand-to-mouth is the primary exposure pathway for lead to children, often dust-wipe testing is the most telling.
These services can help comply with applicable regulations including the California Code of Regulations (CCR), Title 17:
The General and Construction Industry Standard (CCR Title 8):
The HUD Guidelines: Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing
Cal/OSHA requires safeguards for workers if any lead is present.
Because paint/material sampling is often destructive sampling, it may be prudent to sample only those materials to be impacted during the demolition/renovation activities. If materials are not tested, the safest course is to avoid disturbing the suspect materials and to assume untested materials do contain lead.
Building materials that can contain lead include but are not limited to: exterior and interior paints, ceramic floor and wall tile glazing, vinyl mini-blinds, pipes, solder, shielding, cable covering, terne metal roofing, and brick mortar.
