Protection, Access & Site Prep

• Establish safe access to sampling locations; remove or protect obstructions as needed to perform accurate sampling.
• Set up temporary signage and limited-area protection to control foot traffic during sampling.
• Wear required PPE (respirators, disposable coveralls, gloves) per South Coast Air Quality Management District (SCAQMD) Rule 1403 and applicable regulations.

Sampling Procedure

• Collect three bulk asbestos samples from representative suspect materials identified by the client or property representative.
• Use hand tools and methods to minimize disturbance; perform wetting of material as needed to reduce fiber release during sampling.
• Label each sample with unique identifier, location description, sample depth/portion, date, and collector name.
• Chain-of-custody forms will be completed and accompany samples to the laboratory.

Containment & Environmental Controls

• Perform sampling with localized controls (wetting and hand tools) to limit fiber release; no full containment or negative air expected for sampling-only activities.
• Isolate immediate sampling area with poly sheeting or drop cloths as needed to protect underlying finishes and to collect any debris for proper disposal.

Packaging, Transport & Laboratory Analysis

• Package bulk samples in sealed, labeled containers or bags suitable for asbestos bulk analysis.
• Complete and maintain chain-of-custody documentation for transport to an accredited laboratory.
• Submit samples for polarized light microscopy (PLM) or asbestos identification method referenced by SCAQMD Rule 1403 at an accredited laboratory.

Reporting

• Prepare a concise laboratory report package that includes laboratory results, chain-of-custody, sample locations, and photographs of sampling locations.
• Provide a compliance-ready summary noting whether listed materials are asbestos-containing per SCAQMD Rule 1403 thresholds and any recommended abatement actions if asbestos is detected.
• Deliver electronic copies of laboratory reports and the sampling summary to the client and designated representatives; retain originals per regulatory requirements.

Project Timeline & Coordination

• Sampling typically completed within one site visit; laboratory turnaround dependent on lab schedule (standard turnaround estimated 3–7 business days unless expedited analysis is requested).
• Schedule coordinated with property owner/representative to ensure access and to minimize disruption to planned demolition or renovation.

Final Cleaning & Disposal

• Perform site wipe and HEPA-vacuum of localized sampling area and remove protective coverings; collect and dispose of sampling debris as non-friable construction waste per local regulations.
• Leave sampling area in broom-clean condition suitable for subsequent demolition or abatement activities.

Notes / Justification

• Sampling and laboratory analysis are required to determine presence of asbestos and to satisfy SCAQMD Rule 1403 pre-demolition requirements.
• If any sampled material is confirmed asbestos-containing, an abatement plan and licensed abatement contractor will be required prior to demolition; abatement services are not included in this scope.
• Additional samples may be necessary if heterogeneity of materials is observed during sampling; further sampling will be performed as needed and may require separate authorization and charges.
• All work will follow industry-standard practices and applicable regulations; RCR Environmental will maintain chain-of-custody and coordinate lab submissions to ensure defensible results.
