Asbestos, a hazardous material once widely used for its fire-resistant properties, is now recognized for its severe health risks, including lung cancer, asbestosis, and mesothelioma. Conducting an asbestos survey is crucial to managing these risks, whether you’re preparing for renovation, ensuring ongoing safety, or complying with regulations. Here’s a step-by-step breakdown of the process involved in conducting an effective asbestos survey.
1. Pre-Survey Preparation
a. Define Objectives: Before beginning, clearly define the objectives of the survey. Are you preparing for renovation, assessing current conditions, or complying with legal requirements? The purpose of the survey will determine the scope and approach.
b. Gather Existing Information: Review any previous asbestos surveys, building plans, and historical records. Understanding past inspections and renovations can provide valuable insights into potential asbestos locations.
c. Select a Qualified Surveyor: Choose a licensed and experienced asbestos surveyor. In many jurisdictions, surveyors must meet specific certification and competency requirements. Verify their qualifications to ensure a thorough and compliant survey.
2. Conducting the Survey
a. Initial Inspection: The survey begins with a visual inspection of the building. The surveyor identifies areas where asbestos-containing materials (ACMs) might be present, such as insulation, floor tiles, ceiling materials, and pipe lagging.
b. Sampling: The surveyor takes samples of suspected ACMs for laboratory analysis. Sampling involves carefully collecting material from various locations, using personal protective equipment (PPE) to prevent contamination. The number and locations of samples depend on the survey’s scope and the building’s size and complexity.
c. Analysis: The collected samples are analyzed in a certified laboratory. Techniques such as Polarized Light Microscopy (PLM) are used to determine the presence and type of asbestos. The results will indicate whether asbestos is present and, if so, its concentration and type.
3. Reporting and Documentation
a. Report Preparation: After analysis, the surveyor prepares a detailed report. This report includes the findings of the survey, such as the locations and condition of ACMs, their type, and any risk assessments. It may also include photographs and diagrams to illustrate findings.
b. Recommendations: The report provides recommendations for managing or removing ACMs. This may include a management plan for ongoing monitoring and maintenance or a removal plan if the asbestos poses a significant risk.
c. Record Keeping: Proper documentation is crucial. Maintain a copy of the survey report, sampling results, and any associated correspondence. This documentation is important for regulatory compliance and future reference.
4. Implementing the Plan
a. Management or Remediation: Based on the survey report, implement the recommended actions. If the report advises continued monitoring, establish a routine inspection and maintenance schedule. If removal is necessary, engage a licensed asbestos removal contractor to safely remove the ACMs.
b. Communication: Inform all stakeholders, including building occupants and workers, about the presence of asbestos and any necessary precautions. Clear communication helps ensure that everyone is aware of potential risks and safety measures.
Conclusion
Conducting an asbestos survey involves a systematic process of preparation, inspection, sampling, analysis, and documentation. By following these steps, property owners and managers can effectively identify and manage asbestos risks, ensuring the safety of occupants and compliance with regulatory requirements. A well-executed survey not only addresses immediate concerns but also contributes to long-term health and safety in the building.
