Lead and asbestos contamination is frequently encountered during urban construction activities in residential, industrial, and commercial areas with historic uses of asbestos containing material (ACM) and lead-based paint (LBP). The Occupational Health and Safety Administration (OSHA) regulates levels of exposure to lead and asbestos in the construction industry. In addition, similar recommended nuisance standards for dust have been established by the Bay Area Air Quality Management District (BAAQMD) for various types of renovation and demolition in the San Francisco Bay Area.
Asbestos and Lead Based Paint Surveys
ESI provides complete pre-renovation or demolition building surveys for locations and conditions of regulated ACM (RACM) as required by the BAAQMD.
ESI provides building surveys for the presence of LBP using X-Ray Fluorescence (XRF) readings of paint on substrates in accordance with Department of Health Services (DHS) requirements and Housing and Urban Development (HUD) guidelines. LBP Surveys are conducted by a DHS Certified Lead Inspector.
A final Lead and Asbestos Survey Report is prepared and submitted, which includes all contaminant documentation, a risk assessment of hazards at the site, prioritization of required remediation, and budgetary planning for corrective action.
Abatement Project Oversight
ESI has extensive experience in many large and small abatement projects during the past ten years. Our experience ranges from survey and inspection for LBP and ACM to contractor supervision, visual inspections, and air clearance testing in a variety of residential, commercial facilities, and school buildings. ESI’s OSHA certified asbestos consultants and DHS certified lead project monitors can assist your company with compliance with project specification design, and compliance and third party inspection and air monitoring services.
Fungi (MOLD) investigations in commercial and residential buildings
The first sign of mold problems are often deceptive: a moldy smell in part of a building, tired employees or tenants who are said to be suffering from cold or allergies, or visible mold growth on walls, windows or other surfaces in certain locations. These signs are easy to ignore and at times hard to interpret.
People performing cleaning of widespread fungal contamination may be at risk of developing Organic Dust Toxic Syndrome (ODTS) or Hypersensitivity Phenumonitis (HP).
As part of our mold investigation ESI provides consultations and on-site filed services to include:
- Site assessment by visual inspection and humidity measurement
- Bulk and surface sampling to identify specific mold contamination
- Concurrent monitoring of indoor air and outdoor air, when the presence of mold is suspected (e.g., musty odor)
- Analysis of environmental samples by laboratories accredited by the American Industrial Hygiene Association (AIHA)
- Design of site specific remediation options for mold abatement
