Asbestos is not a thing of the past. Despite being banned in many countries, the material still lurks in the nooks and crannies of older buildings. That's why understanding how to conduct a comprehensive asbestos survey is vital for the safety and health of workers and residents in these properties. Navigating the complexities of asbestos survey and best practices can be daunting, but with this guide, you can ensure that no stone is left unturned in your survey efforts.
Understanding the Necessity of an Asbestos Survey
Before any renovation or demolition activity in a building constructed before the 2000s, you must have comprehensive knowledge of your asbestos situation. Disturbing asbestos-containing materials (ACMs) can lead to serious health risks, especially if the fibers become airborne. An asbestos survey is not just a regulatory burden; it's a critical tool to protect lives and prevent potential liabilities.
Regulatory Requirements
Different countries and regions have varying regulations, but the overarching theme is clear – asbestos awareness and handling are strictly controlled. The Control of Asbestos Regulations (CAR) is the key piece of legislation in the UK, whereas the United States enforces the regulations through the Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration (OSHA).
The Importance of an Up-to-Date Survey
An asbestos survey is a snapshot in time that should be regularly updated. Buildings age, materials degrade, and surveys become outdated. Thus, an asbestos survey should be a living document, updated each time there's a change to the building or when a previous survey becomes invalid.
Types of Asbestos Surveys and When to Use Them
There isn't a one-size-fits-all approach to asbestos surveys. Different scenarios call for various types of surveys, each with its own focus and methodology.
Management Surveys
The most common type of survey is the management survey. This survey's purpose is to locate, as far as is reasonably practicable, the presence and extent of any suspected ACMs (or materials which may become ACMs) within the building that could be damaged or disturbed during normal occupancy, including foreseeable maintenance and installation.
Refurbishment and Demolition Surveys
When more invasive work is planned, a refurbishment or demolition survey is necessary. This process is fully intrusive and may involve destructive inspection, as the surveyor must locate all ACMs before the work begins.
The Process of Conducting an Asbestos Survey
The process of conducting an asbestos survey is meticulous and requires a step-by-step approach to ensure nothing is overlooked.
Building a Competent Team
Conducting a survey is not a one-person job. It requires a team of competent professionals, including a surveyor with the right qualifications, a project manager to oversee the survey, and possibly some additional support staff to assist with the inspection and sample collection.
Gathering the Right Tools and Equipment
Proper tools and equipment can make or break a survey. From personal protective equipment (PPE) to sampling kits and labeling materials, your team must have the right gear to ensure their own safety and the integrity of the samples taken.
The Survey Itself
During the survey, areas of the building are to be inspected and samples taken. The surveyor's role here is to identify and assess all potential ACMs, record their locations, and take samples for analysis. This process should be meticulous, thorough, and well-documented.
Interpreting and Acting on Survey Results
The final step in the survey process is to interpret the results. What do the analysis and report mean for the safety of the building and the people within it?
Understanding the Report
Survey reports can be complex documents. Surveyors should work closely with stakeholders to explain the findings and the implications for any planned work.
Taking Appropriate Action
Based on the survey results, different actions will be necessary. For identified ACMs, it might be a case of monitoring or encapsulation. For areas being refurbished or demolished, the ACMs will need careful removal by a licensed contractor.
Conclusion
The process of conducting a comprehensive asbestos survey is not a one-off event but a continuous effort to manage risks and ensure the safety of buildings and their occupants. By following this guide, you set the stage for meticulous surveying that honors not just legal requirements, but the commitment to health and safety that goes beyond regulation. Remember, the diligence you put into a survey today can protect countless lives from the silent dangers that asbestos still presents.
