Lead abatement contractors violating construction standards and regulations can expose you and your company to civil and criminal liabilities. The fiscal risks include: penalties and fines from regulatory agencies, lawsuits from building workers or tenants and damages to your real property. When All Phase Environmental performs construction monitoring and air sampling services, we will protect your interests by having trained and certified professionals on site at all times during the lead abatement process.

We will observe and document compliance with regulations and standards and note the protective measures taken to isolate the work area from the occupants. We will provide on-site direction to correct any errors made by the contractor and to prevent illegal removal of LBP. We will take OSHA personnel samples and area air samples inside the lead removal area to insure the concentration levels are not exposing the contractor’s employees to lead. We will also take air samples outside the lead removal area to insure your building occupants are not exposed to elevated levels of airborne lead concentrations. Our personnel will conduct visual inspections and air sampling to provide you with final project clearance documentation.

Construction monitoring and air sampling records are important legal documents illustrating your responsible actions and protecting you from future liability. Our specialists are California State Certified as well as Certified Lead Abatement Supervisors.

Airborne lead from weathered paint


OSHA has established exposure standards for general contractors working on a site that contains LBP under 29 CFR 1926.62. According to this regulation, workers must not be exposed to greater than the Permissible Exposure Limit (PEL) of fifty micrograms per cubic meter (50 mg/m3). An employer must perform an employee-exposure assessment to determine the magnitude of the exposure actually occurring during a construction activity.

An All Phase Environmental lead expert will come to your construction site and measure the workers exposure to lead. We will observe the work practices and use this information along with the air sample results to provide you with an exposure assessment and recommendations.
