Behind the Walls: Demystifying Asbestos Surveys for Homeowners and Businesses

The mere mention of asbestos often conjures images of dusty industrial settings or concerns over home renovations. But understanding asbestos and its impact is a crucial aspect of maintaining a safe and healthy living and working environment. This comprehensive guide will walk you through the essentials of Asbestos survey, empowering homeowners and businesses alike to make informed decisions about their asbestos-related concerns.

What is an Asbestos Survey?

Before we venture into the depths of what an asbestos survey is, it’s essential to understand the context behind its necessity. Asbestos is a group of naturally occurring minerals found in the environment. Due to its excellent insulating properties and high tensile strength, asbestos gained widespread usage in the late 19th century. However, its microscopic fibers, when inhaled, can lead to significant health risks, such as lung cancer, asbestosis, and mesothelioma.

An asbestos survey is a systematic examination of a building or structure to determine the presence and location of asbestos-containing materials (ACMs). The survey aims to identify any ACMs within the surveyed area, assess their conditions, and recommend the appropriate response. Understanding this process is vital for ensuring safety and compliance with local regulations.

Why Are Asbestos Surveys Important?

The importance of asbestos surveys cannot be overstated. The primary goal of these surveys is to prevent the inhalation of asbestos fibers that can be released from disturbed ACMs. By identifying the location of these materials, property owners can make informed decisions about managing or removing asbestos in a way that is safe and compliant with regulations.

For businesses, a comprehensive asbestos survey forms a part of their duty of care to their employees and customers. Similarly, homeowners who are planning renovations or are concerned about the history of asbestos in their residence can benefit from these surveys to safeguard their families and ensure the integrity of their property.

The Types of Asbestos Surveys

You may be surprised to learn that there isn’t a one-size-fits-all approach to asbestos surveys. The type of survey required depends on the nature and location of the property, the intended refurbishment or demolition work, and the occupancy history. Here are the primary types:

Management Survey

A management survey is the standard survey for most everyday cases. Its purpose is to identify ACMs that could be damaged or disturbed during normal occupancy, including foreseeable maintenance and installation work. The survey findings serve as the basis for managing the risks associated with ACMs.

Refurbishment and Demolition Survey

More comprehensive than a management survey, the refurbishment and demolition survey is required before any refurbishment work, and definitely before a total demolition. The survey is used to locate and describe all ACMs in the area, or the whole building if need be, where the work will take place. The survey findings are used to inform the subsequent management and refurbishment or demolition plan.

Reinspection Survey

Once an asbestos-containing material has been identified, a reinspection survey is conducted to inspect and monitor the condition of the ACM over time. Its goal is to ensure that the ACM remains in a good state and that the risk it poses has not changed.

The Process of Conducting an Asbestos Survey

Irrespective of the type of survey necessary, there is a standard method for performing asbestos surveys. It involves a series of steps that are detailed and thorough:

Pre-Survey Planning

Before the actual survey takes place, the surveyor should thoroughly plan the site visit. This planning phase includes researching the building’s history for any known use of asbestos and preparing the necessary equipment, such as personal protective gear and sampling tools.

On-Site Inspection

The surveyor will conduct a detailed and systematic inspection of the building’s interior and exterior, including all spaces where asbestos could potentially be present. The surveyor will examine all materials suspected of containing asbestos and record their location, extent, and condition.

Material Sampling and Analysis

In areas where asbestos is suspected, the surveyor will take material samples. These samples will be sent to a laboratory for analysis to confirm the presence of asbestos and determine the type and concentration of fibers in the material.

Documenting Survey Findings

All survey findings are documented in a survey report, which includes detailed information on the location and condition of asbestos, risk assessments, and recommendations for managing or removing the materials. The survey report is a legally required document and should be kept in the building’s asbestos register, available for reference by workers, or anyone planning work in the building.

Understanding Asbestos Survey Reports

The survey report is the most important takeaway from the asbestos survey process. It includes a wealth of information that you need to understand to act on the survey findings. The report typically consists of several sections, including:

Executive Summary

The executive summary provides an overview of the survey’s purpose, key findings, and any immediate actions recommended. It’s a useful section for those who want to quickly grasp the state of asbestos in the building.

Sample Data

Details of the samples taken—where from, the material type, and the analysis—will be included in the report. This data is crucial in understanding the extent of asbestos in the building.

Recommendations

This section outlines the suggested actions to take based on the survey findings. These recommendations could include anything from in-situ management to full asbestos removal, depending on the risks identified.

Laboratory Analysis Results

The laboratory results should be straightforward, stating the type and concentration of asbestos found. Sometimes, ‘presumptive’ or ‘materials containing asbestos’ conclusions may indicate a requirement for further action, such as treating the material as if it were ACM.

Risk Assessment

A risk assessment evaluates the condition of the materials and the likelihood of fibers being released. It aids decision-making around management and can help prioritize actions.

Responding to Asbestos Survey Findings

The response to survey findings depends on the nature and location of the ACMs, as well as the recommendations provided by the surveyor. There are a few possible courses of action:

Managing In Situ

This means leaving the asbestos-containing materials in place but managing them to prevent exposure. Actions can include sealing, covering, or encapsulating the materials to make sure they can’t be disturbed.

Enclosure

Physical enclosure can be used for materials in good condition, preventing anyone from coming into contact with the ACMs.

Regular Monitoring

If the asbestos is in good condition, it may be sufficient to keep it under regular supervision to ensure that the risk remains low.

Removal

In some cases, the safest option is complete removal of the asbestos-containing materials. This must be carried out by a licensed contractor following strict regulations.

Emergency Removal

If the asbestos is highly damaged or in an area where disturbance is imminent, it may need to be removed as soon as possible.

Information, Instruction, and Training

It is crucial to provide information on the location and condition of the identified ACMs to anyone who may be affected, along with the necessary instructions and training.

Hiring an Asbestos Surveyor

Choosing the right asbestos surveyor is a significant task. The surveyor should be competent, accredited by a recognized authority, and have sufficient experience in conducting surveys. When hiring a surveyor:

Request and review their qualifications and training records.

Inquire about their previous experience, particularly in properties similar to yours.

Ensure they have professional indemnity insurance.

Obtain references from their previous clients if possible.

Discuss the proposed survey methodology and ensure it aligns with the expected scope of work.

The Future Role of AI in Asbestos Surveys

Artificial Intelligence and machine learning technologies are making their foray into asbestos surveying, promising to revolutionize the field. These technologies can be used to automate some aspects of surveys like data collection and analysis, reducing human error and subjectivity. Such advancements will possibly result in more efficient surveys and faster insights into asbestos risks.

The Law and Asbestos Surveys

Understanding legal requirements is crucial for any business or homeowner when it comes to asbestos. Different jurisdictions have varying regulations, and it is important to stay updated. In the United States, for example, the Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration (OSHA) enforce regulations pertaining to asbestos surveys in different contexts, such as residential properties, public buildings, industrial settings, and construction sites.
