Step-by-Step Guide for Building Owners Suspecting Asbestos in Their Building

As a building owner, discovering or suspecting that asbestos materials may be present in your property can be a daunting realization. Asbestos, commonly used in construction materials up until the 1980s for its fire-resistant properties, is now known to cause serious health risks if fibers become airborne. This guide will walk you through the steps necessary to handle asbestos in your building responsibly and in compliance with legal regulations.

Step 1: Identify Potential Asbestos Materials

Know Where Asbestos May Be Found Asbestos was used in a variety of building materials. Some common locations where asbestos-containing materials (ACMs) are found include:

  • Roofing materials and shingles
  • Insulation (around pipes, boilers, walls)
  • Vinyl floor tiles and adhesives
  • Cement sheeting (walls, ceilings, and roofs)
  • Textured ceilings (e.g., popcorn ceilings)
  • Fireproofing materials

If your building was constructed or renovated before the 1990s, it is possible that asbestos may be present.

Handy Tip: Don’t assume that just because asbestos is present, it’s dangerous. Asbestos is primarily hazardous when disturbed and fibers are released into the air. Intact and well-maintained asbestos materials may not pose an immediate threat.

Step 2: Do Not Disturb the Suspected Asbestos

Avoid DIY Testing or Removal Asbestos becomes a health risk when fibers become airborne, which can happen if the material is broken, drilled into, or disturbed in any way. For this reason, avoid touching, cutting, or otherwise disturbing suspected asbestos materials. Keep the area sealed off and limit access until professionals can inspect the situation.

What You Shouldn’t Do:

  • Don’t attempt to sand, cut, or break up the suspected material.
  • Avoid using a vacuum or sweeping, as this can cause fibers to become airborne.
  • Don’t try to test or remove the material yourself.

Step 3: Hire a Licensed Asbestos Inspector for Testing

Engage a Professional for Testing The only way to confirm the presence of asbestos is to have a licensed asbestos inspector conduct a professional inspection. The inspector will safely collect samples of the suspected materials and send them to a laboratory for analysis. It is crucial that this is done by a licensed professional, as improper sampling could release asbestos fibers into the air.

Cost Estimate: The cost of an asbestos inspection typically ranges between $400 and $800, depending on the size of the building and the number of samples required.

What to Expect from the Inspection: You will receive a comprehensive report detailing whether asbestos is present, its location, and its condition. The inspector will also provide recommendations on whether the asbestos should be removed or encapsulated.

Step 4: Decide Between Removal or Encapsulation

Understand Your Options If asbestos is confirmed in your building, you’ll have two options: encapsulation or removal.

  • Encapsulation: This process involves sealing the asbestos materials with a special coating that prevents fibers from becoming airborne. This is often more affordable and is a good option if the asbestos is in good condition and unlikely to be disturbed.
  • Removal: If the asbestos materials are damaged, deteriorating, or at risk of being disturbed (e.g., during renovations or demolition), removal is the best option. Removal is a more permanent solution but is more costly and must be handled by licensed asbestos abatement professionals.

Cost Estimate:

  • Encapsulation typically costs between $500 and $2,000, depending on the area that needs to be treated.
  • Asbestos Removal can cost anywhere from $1,500 to $30,000, depending on the extent of the contamination and the size of the building.

Step 5: Comply with Legal Requirements and Health & Safety Regulations

Follow WorkSafe NZ and Health and Safety at Work Act 2015 Guidelines In New Zealand, asbestos-related work must comply with strict regulations set out by WorkSafe NZ and the Health and Safety at Work Act 2015. As the building owner, it’s your responsibility to ensure that any asbestos removal or management is carried out by licensed professionals.

If asbestos is found, you may also need to maintain an Asbestos Management Plan for your building. This document outlines the location of asbestos, its condition, and how it will be managed to prevent exposure.

What the Law Requires:

  • Only licensed asbestos professionals can handle testing and removal.
  • You must inform workers and anyone on-site about the presence of asbestos and how it will be managed.
  • You are required to keep an asbestos register and update it regularly if asbestos remains in the building.

Step 6: Ensure Proper Disposal of Asbestos

Safe and Legal Disposal Asbestos waste must be disposed of at approved facilities. Licensed asbestos removal professionals will transport the waste in sealed containers to prevent any asbestos fibers from being released during transportation. Never dispose of asbestos in regular rubbish or recycling bins—this is illegal and dangerous.

Disposal Tip: Ask the asbestos removal contractor for proof of proper disposal. Keeping records of the process can be important for future property transactions or legal purposes.

Step 7: Obtain a Clearance Certificate After Removal

Final Inspection and Certification Once the asbestos has been removed, a final inspection should be conducted by an independent inspector. This ensures that the removal was done properly and that no asbestos fibers remain in the air. Upon passing the inspection, you will receive a clearance certificate, which is crucial for documentation and regulatory compliance.

Cost of Clearance: A clearance certificate typically costs between $200 and $500, depending on the size of the building and the extent of the testing.

Conclusion

Managing asbestos in your building requires careful planning and adherence to strict safety protocols. Whether you opt for encapsulation or removal, always hire licensed professionals to carry out testing and abatement work. Following the steps outlined in this guide will help you manage the asbestos safely, comply with New Zealand’s health and safety regulations, and ensure the well-being of everyone in your building. Taking swift and responsible action now will protect you from future liabilities and preserve the value of your property.
