Asbestos Removal Clearance
We don't remove asbestos, but we're fully licensed to conduct asbestos removal clearance inspections following asbestos removal
An asbestos assessor provides a new pair of eyes, using an internationally recognized procedure to ensure and validate that an area where asbestos has been removed is fit for reoccupation.
When conducting asbestos removal clearances our aim is to provide a fair pragmatic approach to help our clients complete the job without compromising our duties.
All of our licensed asbestos assessors are qualified in the British Occupational Hygiene Society’s proficiency certificate IP404 for Air Monitoring, Clearance Inspections and Reoccupation Following Removal of Asbestos.
Asbestos assessor licenses are issued by Worksafe NZ. An individual must be a suitably qualified and experienced practitioner and have relevant experience conducting asbestos clearances. They must have a strong understanding about asbestos materials, their nature when disturbed, and how they affect the surfaces around them.
When asbestos is being removed, whether it is an A Class friable material or B Class non-friable material, a clearance inspection must be carried out by a licensed asbestos assessor. An asbestos assessor must be separate from the company removing the asbestos to ensure impartiality.

The Four Stage Clearance Procedure
Stage 1: Preliminary Check
We’ll come have a look at the sites condition and level of completeness
Inside the Enclosure
A thorough inspection will take place inside the work area
To detect whether fibres released during and after removal are below trace level, we’ll conduct air monitoring
Stage 4: Without the enclosure
If all requirements are met, we’ll conduct the final assessment of the work area to check it is fit for reoccupation
With all stages of the four stage clearance complete we will then issue a clearance certificate for your client and for your records.
It is important to note that some items usually considered as B Class materials have the potential to become friable depending on their condition, how they will react during removal, or if friable materials are part of a non-friable material.
Consideration should be taken as to whether an item should be removed as A Class work.
Friable A Class
Removal of A Class materials requires stronger control measures, as friable materials are very high risk. They have a higher potential for exposure to those carrying out the work. Friable removal of materials such as sprayed coating tend to bring back high air monitoring results and so the level of PPE & RPE for workers must be adequate for those conditions.
Friable A Class materials include:
Pipe Lagging & Thermal Insulation
Asbestos Insulating Board & Millboard
Ropes & Paper Products
Non-Friable B Class
Removing non-friable bonded materials is a lower risk job than working with friable materials. The same risks of exposure are present, but the amount of fibre likely to be released will differ greatly. Air Monitoring is not a requirement of a B Class removal clearance, but can be an optional method of reassurance.
Non-Friable B Class materials include:
Gaskets & Washers
Textured Coatings (Decorative Ceilings)
Asbestos Removal Company Getting a Clearance?
If you’re an asbestos removal company engaging Fibresafe NZ to conduct your removal clearance inspection, here are some tips about what we’ll be looking for before and when we come to visit your work site.
Asbestos Removal Control Plans
ARCP’s are crucial parts of your removal work, same for our assessor work. We need these documents to be spot on so that we understand the scope. They’re also mandatory.
Remember this document also needs to clearly state:
Non-asbestos hazards such as slips & trips, work at height, etc.
A Method Statement with details of the site, type of work, control measures, item types and conditions, which staff will carry out the work, and transport routes for waste and disposal.
There needs to be a Work Area Plan detailing where decontamination and negative pressure units are, enclosures, all entrances and exits for the removal site, warning signage, and where waste will be contained.
Planning & Time Management
We understand the time pressed nature of removal work. But we like a heads up when we’re needed to conduct a clearance, or when you need a little more time before we pop round.
To schedule a clearance you can send an email to email@example.com or contact us here, or give us a call on either (04) 568 4142 or 0800 333 212. We’ll make sure we’ve got a team member ready for the times you need.
You also need to make sure your notification to Worksafe NZ has been sorted for the right time period. This is a great time to let us know to set aside time for your clearance inspection.
We need to know your control measures. It’s always important to remember which measures work most effectively. This helps to decide whether you are using the best controls for the job.
From most effective:
Elimination & Substitution – You’re removing the asbestos, so you could say you’re physically removing the hazard, but have you eliminated non-asbestos hazards?
Engineering Controls – reducing the fibres at the source
- Wetting Techniques
- H-Class Vacuuming with shadowing
- Access Restrictions, barriers & warning signage
- Tools & equipment
- Glove bags
- Wrap & cut methods
Administration controls – Training is a must, but also those toolbox talks & communication can go a long way in improving worker health & safety. Also your SOP’s and JSA’s.
PPE & RPE – The last line of defense.
Personal Protective Equipment & Respiratory Protective Equipment needs to be adequate for the job. Boots, gloves, eye protection, hearing protection, hard hats & coveralls must be appropriate for asbestos removal work.
By knowing which control measures are best to use from the start, you can avoid having to elevate the measures used when air monitoring results come back too high.
Removal Work & What We Check
Our duty as asbestos assessors requires us to check much more than just the item being removed. We must assess the job as a whole.
Things we need to check include:
- Enclosure integrity & design
- Decontamination units & routes
- Airlocks & baglocks
- Negative Pressure Units
- Worker Personal Protective Equipment (PPE)
- Worker respiratory protective equipment (RPE)
- Non-asbestos hazard management
- Site access control
- Settled dust
- Waste management
- Asbestos Removal Control Plans
- Worksafe notifications
- Removal area wetness
- Compliance with the Health & Safety at Work (asbestos) Regulations 2016
