Regulation and guidance referenced
CAR 2012 Regulation 7 — Plan of work for licensed and notifiable non-licensed work (HSE)
Requires a written plan of work covering nature and probable duration, location, methods, equipment, controls, decontamination and waste route before work starts.
HSG247 — Asbestos: The licensed contractor's guide (HSE)
Practical guidance on enclosures, NPUs, smoke testing, transit and decontamination — the method statement should mirror its structure.
HSG248 — Asbestos: The analysts' guide (HSE)
Defines four-stage clearance; method statements must reference how analyst hold-points are built into the sequence.
ACOP L143 — Managing and working with asbestos (HSE)
The approved code of practice supporting CAR 2012 — referenced by inspectors during enforcement.
Common mistakes that get this document rejected
No four-stage clearance hold-point
Many removal method statements describe enclosure construction but skip how Stage 1–4 clearance is sequenced before reoccupation. Inspectors and principal contractors look for this explicitly.
Generic decontamination unit reference
A DCU has to be described with location, water and waste route, transit procedure, and how it's used by everyone leaving the enclosure — 'DCU on site' is not enough.
Waste route missing the consignment note
Asbestos waste is hazardous waste — the document needs the carrier, consignment note process and destination site, not just 'removed off site'.
Worked example
Scenario: Strip-out of asbestos insulating board (AIB) ceiling tiles in a 1970s school during half-term.
What went wrong: First method statement rejected by the principal contractor for missing the smoke test record, no NPU change-rate calculation, no analyst booking confirmation, and a generic 'PPE as required' line.
The fix: Rebuilt with named NPU (rated for enclosure volume), smoke test as a hold-point before stripping, analyst booking number, PPE specified by task (RPE FFP3 with face-fit, disposable Type 5/6 coveralls), and a four-stage clearance signed by the analyst before handover.
Outcome: Accepted on resubmission. Stage 4 clearance certificate retained with the project H&S file under CDM 2015.
