How to Prevent Asbestos Exposure

Owner-Led Direct Scope · Verified Owner NL01 Training · Providers Confirmed Per Instruction · Work Category Checked Before Work

Asbestos exposure can cause serious disease, and the practical prevention priority is to stop avoidable disturbance before it occurs. Adequate asbestos information, correct work classification and task-specific controls are more useful for a current building decision than using a historical disease statistic to judge the risk of one material or incident.

The UK banned all asbestos use in November 1999. The materials that remain in buildings are known, their locations can be identified through surveys, and the legal framework governing their management and removal: the Control of Asbestos Regulations 2012 (CAR 2012): is comprehensive. The exposures that still occur today happen primarily because ACMs are disturbed without prior identification, because non-licensed work is carried out without appropriate RPE, or because licensed work is attempted by unqualified individuals.

Prevention starts with knowing whether asbestos may be present in the work area, using controls appropriate to the assessed task and using an HSE-licensed contractor where the work is licensable. The exact duties depend on the work category, so a generic checklist does not replace the job-specific risk assessment and plan of work.

01

Before maintenance, refurbishment or demolition disturbs suspect building fabric, make sure the asbestos information is adequate for the area the work will affect. Existing records may be enough in some situations; where they are not, use the competent survey or sampling route appropriate to the planned work.

02

Confirmed asbestos-containing material in good condition may sometimes be managed in place where it is unlikely to be disturbed. Record what is known, monitor the condition where a dutyholder arrangement applies, and reassess before later work that could damage or disturb it.

03

The material, condition and task determine whether work is non-licensed, notifiable non-licensed work (NNLW), or licensable. Sprayed asbestos coatings and asbestos thermal insulation such as pipe lagging require an HSE-licensed contractor, and most AIB removal is also licensable. Some short-duration minor AIB tasks can be non-licensed or NNLW, so do not classify work from the material name alone.

04

For non-licensed or NNLW work, the risk assessment and plan of work determine the controls needed for the actual task. HSE Asbestos Essentials provides task sheets for lower-risk work. This guide does not turn wetting, drilling or removal techniques into a DIY instruction.

05

Respiratory protective equipment must be selected for the task, wearer and expected exposure, and tight-fitting RPE must be face-fit tested. A generic mask recommendation on a webpage is not a substitute for the job-specific risk assessment, training and equipment selection required for asbestos work.

06

The containment, enclosure, decontamination and air-monitoring arrangements depend on the work category and task. Licensed enclosure work uses the controls set by the HSE-licensed contractor and, where four-stage clearance is required, an independent analyst. Non-licensed and NNLW tasks use the controls appropriate to those tasks rather than a universal enclosure rule.

07

Asbestos waste must be packaged, transported and disposed of through the applicable hazardous-waste route. Where a hazardous-waste consignment note is required, it forms part of the movement records. The carrier, receiving facility and exact paperwork are job-specific rather than one universal document bundle.

Respiratory protective equipment is one part of the control system and must be suitable for the assessed task, wearer and required protection factor. HSE asbestos task guidance commonly specifies suitable RPE such as FFP3 or a half-mask with a P3 filter for particular non-licensed tasks, but this page does not set one respirator as a universal rule for every asbestos job. Face fit, correct use and the rest of the task controls still matter.

RPE must be face-fit tested before use. An incorrectly fitted respirator: even a P3-rated one: provides significantly reduced protection. Face-fit testing is a legal requirement under CAR 2012 for all asbestos work.

Property age or appearance cannot prove what a material is. Check existing records and use a competent survey or sampling route where planned work could disturb suspect material.

Breaking or substantially damaging asbestos cement can increase fibre release and can change the work classification. Keep sheets intact where the approved task method requires it and use a competent work route.

Drilling, cutting or abrading can disturb asbestos fibres. HSE task guidance and the job-specific risk assessment determine whether the work is permitted and what controls are required.

Asbestos waste follows the applicable hazardous-waste route. Check the accepted packaging, carrier and receiving facility before waste is moved.

Visual inspection cannot confirm asbestos content. If the answer matters before disturbance, use reliable records or the appropriate sampling and laboratory-analysis route.

Most AIB removal is licensable, but some short-duration minor AIB tasks can be non-licensed or NNLW. The material condition, task and risk assessment determine the route.

The Control of Asbestos Regulations 2012 (CAR 2012) is the primary legislation governing asbestos management and removal in the UK. It applies to all non-domestic premises and to domestic premises where work is being carried out. The key duties relevant to exposure prevention are:

Regulation 4

Duty to manage asbestos in non-domestic premises: requires the dutyholder to identify ACMs, assess their condition, and implement a written management plan.

Regulation 7

Plans of work and asbestos information must be adequate for the work. Before intrusive refurbishment or demolition, use the appropriate survey route where existing information is insufficient for the areas to be disturbed.

Regulation 8

Licensable work must be carried out by an HSE-licensed contractor. Sprayed asbestos coatings and asbestos thermal insulation such as pipe lagging use this route, and most AIB removal is also licensable; some short-duration minor AIB tasks can fall outside licensing where the criteria are met.

Notification duties

Licensable work and NNLW use different notification routes and duties. The contractor responsible for the assessed work category must follow the notification requirements that apply to that job.

Information & training

People liable to disturb asbestos need information, instruction and training appropriate to the work. Awareness training is not sufficient for carrying out non-licensed/NNLW work, and provider branding is not a legal substitute for task-appropriate competence.

Waste duties

Asbestos waste follows the applicable hazardous-waste route, with packaging, carrier, receiving-facility and consignment-note requirements determined by the actual movement.

Enforcement note: Asbestos duties are enforced by the relevant enforcing authority. The practical compliance point for this guide is to establish the material and work category before disturbance, use competent people for the task and keep the required work and waste records. This page does not publish penalty figures or enforcement fees as a substitute for current regulator guidance.
