RAMS for Asbestos-Related Work

Asbestos remains the single largest cause of work-related deaths in Great Britain. Any task that may disturb asbestos-containing materials (ACMs) in a pre-2000 building demands a RAMS that goes well beyond a generic risk assessment. Get it wrong and the consequences are criminal prosecution, enforcement notices, and — most seriously — long-latency disease in your operatives.

Legal Basis

The duty to carry out a suitable and sufficient risk assessment sits in the Management of Health and Safety at Work Regulations 1999 (MHSWR), Regulation 3. For asbestos specifically, the Control of Asbestos Regulations 2012 (CAR 2012) is the principal instrument. Regulation 4 places a duty to manage asbestos on the dutyholder of non-domestic premises. Before any work that is liable to disturb ACMs, Regulation 7 of CAR 2012 requires an assessment of the type, condition, and extent of the material to establish the risk and the appropriate work category.

The three work categories under CAR 2012 are: licensable work (highest risk — mandatory use of a Health and Safety Executive (HSE) licensed contractor, notification to the HSE, and medical surveillance); notifiable non-licensed work (NNLW — lower-risk materials, but still notifiable to the relevant enforcing authority, with health records kept for 40 years); and non-licensed work (lowest risk, no notification, but a risk assessment and appropriate controls are still required). The distinction turns on the material type, fibre release potential, duration, and frequency of exposure. When in doubt, treat the category as higher, not lower.

Key Hazards and Controls

**Identify before disturbing.** For any pre-2000 building, a CAR 2012 refurbishment and demolition (R&D) survey — or at minimum a management survey — must be completed and reviewed before the scope of work is finalised. Starting work without a survey is one of the most common enforcement triggers.

**Control limit.** The CAR 2012 control limit is 0.1 fibres per cubic centimetre (f/cm³), averaged over four hours. No work should proceed where a competent assessment suggests this will be exceeded without full licensed controls in place.

**Hierarchy of controls applied in order:**

Eliminate: where possible, leave undisturbed ACMs in good condition alone and work around them. An encapsulation or sealing approach may avoid disturbance entirely.

Engineering controls: establish a physical enclosure (negative-pressure unit where required for licensable work); use wet methods throughout to suppress fibre release; employ continuous damping of cut edges. Use H-class (HEPA-filtered) vacuum equipment — a standard vacuum will not capture asbestos fibres. Provide decontamination facilities (airlock/bag-lock system) before personnel exit the work area.

Administrative controls: restrict access with physical barriers and signage; use a permit-to-work system; limit the number of people in the enclosure; ensure all operatives hold a current UKATA (or equivalent) asbestos awareness certificate as a minimum, or the appropriate licensed-work training for licensable tasks; maintain a detailed work plan.

PPE — applied last and never as the sole control: respiratory protective equipment (RPE) must be adequate for the fibre concentrations expected. For licensable work, a minimum of a half-mask FFP3 is rarely sufficient — full-face air-purifying or air-fed RPE is typically required. Disposable coveralls (Type 5/6) are single-use and must be double-bagged in the enclosure before removal.

**Air monitoring** should be carried out during the work and as clearance testing post-removal. Only a UKAS-accredited laboratory should carry out clearance air testing.

**Waste** must be double-bagged in UN-approved asbestos waste sacks, clearly labelled, and disposed of at a licensed waste facility. Asbestos waste is classified as hazardous waste under the Hazardous Waste (England and Wales) Regulations 2005.

Common Failings That Get a RAMS Rejected

The following are the most frequent reasons an asbestos RAMS is turned back by a principal contractor or HSE inspector: no survey reference or survey findings not reviewed before the RAMS was written; work category incorrectly assigned (licensable work described as NNLW); RPE selection not matched to the fibre release potential of the specific task; no decontamination procedure described; waste segregation and disposal route absent; no air monitoring plan; operatives' training and medical surveillance records not addressed.

What the Document Must Include

A suitable and sufficient asbestos RAMS must cover: the scope of work and location of identified ACMs with reference to the survey; the CAR 2012 work category and the basis for that classification; the risk assessment showing how the control limit is to be maintained; details of enclosure design, wet methods, and H-class vacuum use; the RPE specification with assigned protection factor; decontamination procedures; air monitoring arrangements (background, during-work, and clearance); operative training evidence and, where required, medical surveillance arrangements; waste management and consignment-note process; and emergency arrangements in the event of uncontrolled fibre release. Where the work is licensable, the HSE notification reference and the name of the licensed contractor must be included.
