6. Material Description and Class B Assessment

Decramastic roofing commonly consists of pressed metal tiles with a textured bituminous and stone-chip coating. Some older coatings may contain asbestos. For this ARCP the material is treated as asbestos-containing material confirmed by sample, survey or presumption. Removal is Class B only if the material is non-friable and can be removed whole or in manageable sections without breaking, grinding, sanding, drilling or creating airborne asbestos dust.

  • No water blasting or high-pressure cleaning is permitted.
  • No dry sweeping, compressed air, uncontrolled scraping, grinding or abrasive cutting is permitted.
  • Damaged, brittle or loose coating must be dampened, stabilised and handled carefully. Stop work if friable conditions are suspected.
  • Disposable Type 5/6 coveralls with hood; taped cuffs if required by site conditions.
  • P2/P3 half-face or full-face respirator suitable for asbestos work and fit-tested to the worker; clean-shaven seal area required.
  • Safety boots that can be decontaminated or disposable boot covers as required.
  • Nitrile/disposable gloves and cut-resistant outer gloves where handling sharp roofing edges.
  • Safety helmet, eye protection and hearing protection where required.
  • Fall prevention equipment: scaffold/edge protection, safe access ladder, roof ladder/crawl boards, exclusion below work area.
  • Low-pressure sprayer/mist bottle with amended water/wetting agent.
  • H-Class asbestos vacuum with suitable HEPA filtration and current inspection/service record.
  • 200 micron polythene, asbestos waste bags, asbestos warning labels, duct tape, wrap, wipes, buckets and waste bins/skip lined for asbestos waste.
  • Warning signs, barricades, cones, barrier mesh and site contact signage.
  • Emergency spill/fibre release kit.
  • No water blasting or high-pressure washing of asbestos roofing.
  • No grinding, sanding, abrasive cutting, drilling or use of compressed air on ACM.
  • No dry sweeping or use of domestic/general-purpose vacuum cleaners.
  • No eating, drinking or smoking in the asbestos removal area.
  • No unauthorised access into the exclusion zone.
  • No continuation of work if ACM becomes friable or conditions exceed Class B controls.
  • Use double bags or double wrapping with minimum 200 micron polythene or approved asbestos waste bags.
  • Do not overfill bags; maintain manageable weight and prevent puncture.
  • Seal all packages with tape and label clearly as asbestos waste.
  • Clean the outside of waste packages before removal from the asbestos work area.
  • Secure loads during transport and prevent damage to wrapped packages.
  • Retain disposal receipts/dockets and photographs as close-out evidence.
  • Hold Point 1: Asbestos survey/sample confirmed and Class B suitability accepted by supervisor.
  • Hold Point 2: WorkSafe notification completed where required and ARCP available on site.
  • Hold Point 3: Scaffold/edge protection inspected and signed off before roof access.
  • Hold Point 4: Exclusion zone, signage, decontamination and waste area established before removal starts.
  • Hold Point 5: Stop work and reassess if ACM breaks down, becomes friable, or weather conditions change.
  • Hold Point 6: Final visual inspection/clearance completed before handover or follow-on trade access.
  • Workers must be trained and competent for Class B asbestos removal work and understand this ARCP.
  • Workers must have respirator fit testing and be trained in correct PPE/RPE use, limitations and maintenance.
  • Workers must be trained in decontamination, waste wrapping/labelling, emergency response and working at height controls.
  • The supervisor must verify competency before work starts and record attendance at the pre-start briefing.

10. Step-by-Step Removal Method

Step

Action

Key Controls / Hold Points

1

Site arrival and setup

Park safely. Sign in. Confirm site address, work area and emergency access. Set up signage, barriers and exclusion zone. Confirm first aid, fire extinguisher and emergency contacts.

2

Review documents

Review asbestos survey, ARCP, SWP, WorkSafe notification, training records, respirator fit test records and disposal arrangements.

3

Confirm access and fall controls

Inspect scaffold/edge protection, ladders, roof access, fragile roof areas and ground exclusion zone. Do not access roof until controls are confirmed.

4

Prepare decontamination and waste area

Set up clean/dirty transition area, wet wipes, H-Class vacuum, asbestos bags/wrap, labelled waste storage and lined waste bin/skip.

5

Pre-wet work area

Lightly mist the immediate removal area to suppress dust. Avoid water run-off. Do not water blast.

6

Remove fixings carefully

Remove fasteners by hand or using controlled low-speed methods only if they do not abrade or damage ACM. Do not grind or cut through ACM.

7

Remove tiles/sheets whole

Lift and remove decramastic tiles/sheets whole where practicable. Avoid snapping, dropping or scraping coating. Lower materials in a controlled manner.

8

Manage damaged pieces

Mist damaged edges/pieces, place directly into asbestos waste bags or wrap. Treat all debris, stone chips, wipes and disposable PPE as asbestos waste.

9

Progressive cleaning

Use H-Class vacuum and wet wiping as work proceeds. Do not dry sweep. Keep gutters, scaffold platforms and ground protection clean.

10

Waste wrapping and labelling

Double-wrap or double-bag waste in 200 micron polythene or approved asbestos bags. Seal with tape and apply asbestos warning labels. Clean external surfaces before moving through clean areas.

11

Final clean

H-Class vacuum and wet wipe roof structure, scaffold platforms, gutters, ground protection and affected surfaces. Inspect for visible asbestos debris.

12

Clearance / handover

Arrange clearance inspection/visual clearance as required. Do not allow follow-on trades or demolition until the asbestos removal area is confirmed clean and released.

11. Prohibited Work Practices

12. Decontamination Procedure

13. Waste Transport and Disposal

All asbestos waste must be packaged to prevent fibre release, labelled as asbestos waste, kept secure, and transported to an approved asbestos waste facility. Disposal dockets and waste records must be retained with the project file.

14. Air Monitoring and Clearance

For Class B non-friable asbestos removal, air monitoring may be required based on client requirements, site conditions, proximity to neighbours/occupied areas, deterioration of ACM, enclosure decisions, or risk assessment. Clearance must confirm the asbestos removal area is visually free of asbestos debris before reoccupation or follow-on work. Where required, engage an independent competent person/licensed asbestos assessor.
