Asbestos surveying and risk assessment
Candidates for this course are expected to be aware of the contents of HSG264 Asbestos: The survey guide and have a minimum of six months prior experience of carrying out asbestos surveys.
To provide candidates with background and practical knowledge in the surveying of buildings for asbestos and to provide general guidance on management procedures necessary to minimise exposure to any identified asbestos.
1. Introduction and Legislative Requirements
- Introduce the requirements for management of asbestos in buildings under the Management of Health and Safety at Work Regulations 1999, the Control of Asbestos Regulations 2012 and the Construction (Design and Management) Regulations 2007.
- Communication and reporting: explain the requirements to communicate clearly with colleagues and clients and report findings in a formal manner.
2. Asbestos in Buildings
Types and Uses of Asbestos in Buildings
- Use of reference documents (1) (2) (9) as a primary source of information on products and their locations in buildings.
- Explain the physical and chemical properties of asbestos which have determined the use to which it has been put by industry.
- Discuss the three types of asbestos which have found significant commercial use (Amosite, Chrysotile and Crocidolite) in relation to sprayed and thermal insulation, insulating boards, coatings, cement products and other reinforced products (eg vinyl tiles, roofing felts) commonly used in building construction.
- Describe the full range of health effects ranging from the benign (pleural plaques) to the terminal (mesothelioma) in the light of results from epidemiological studies carried out on asbestos workers. Review influential publications. Cover dose-response relationships, the effects of smoking whilst working with asbestos and the risks to health from low-level exposure.
- Discuss the uses and composition of other asbestos products likely to be used or found inside buildings on plant, machinery or domestic appliances (eg textiles, friction materials, seals, gaskets etc).
- Describe the use and occurrence of the other types of asbestos particularly as possible contaminants in other minerals.
Surveys of Asbestos-Containing Materials in Buildings
- Discuss the types of survey which can be carried out.
- Discuss how to plan, organise and conduct surveys. The importance of the survey plan, what information should be collected and included within the plan and the requirement to involve the client in this process.
- Discuss what parameters need to be assessed and recorded during the survey. i.e. location, product type, accessibility, condition, surface treatment, materials which could be confused as containing as asbestos.
- Discuss typical errors and how to present results and record location of asbestos containing materials, including the use of caveats and the requirement for these to be site specific and not generic.
- Discuss the level of access required for each type of survey and the potential for a phased approach for demolition/refurbishment surveys.
- Discuss the quality control measures which the client will be expected to implement following receipt of survey reports.
- Discuss the various safety precautions required during survey work including an initial risk assessment and PPE requirements.
- Discuss the detailed reporting requirements for asbestos surveys.
3. Risk Assessments and Management of Asbestos
- Risk Assessment of Asbestos-Containing Materials in Buildings
- Examine the purpose and strategies for risk assessment of asbestos containing materials in buildings and the compilation of asbestos registers. Outline the types and sources of information required and discuss the uses to which this information is put.
- Describe the different assessments that are required and how these help determine control actions. Outline possible control actions. Describe common errors in the survey and risk assessment process.
- Discuss the steps necessary to manage identified asbestos in buildings i.e. location survey, asbestos register, risk assessment, written plan of control actions.
- Outline the on-going management actions necessary to minimise exposure to identified asbestos in buildings, ie maintain register, monitor condition, label, restrict access, inform, train, define and use safe systems of work, operate a permit to work system.
4. Bulk Sampling and Personal Decontamination
- Outline the numerous reasons for bulk sampling ranging from the collection of one small sample for identification purposes through to a complete survey of a building in order to compile an asbestos register.
- Discuss the quality and quantity of information required to enable valid conclusions to be reached and relevant recommendations to be made.
- Discuss sampling strategies for all types of asbestos containing materials i.e. spray coatings, pipe insulation, insulating board, ceiling tiles, cement materials.
- Describe fully the techniques used and precautions required when collecting bulk samples.
- Discuss face fit testing, the selection and use of PPE and RPE, its place in the control hierarchy and likely protection it affords.
- Discuss transit and decontamination procedures that may need to be followed and medical records that may need to be kept together with other risk assessments that may be necessary.
5. Practical Work
- Identifying the presence of asbestos and its types in different locations.
- Understanding of buildings and structures.
Surveying and Sampling Techniques
- Level of intrusion required for the different types of survey.
- Situations where segregation would be necessary plus the appropriate methods to achieve this.
- Sampling protocol and strategies.
- Procedures for taking samples from a range of products and locations.
Safety Requirements for Surveying
- Personal protection and safety including requirements of risk assessments.
- The range of appropriate PPE and RPE and techniques for decontamination.
Post Survey Evaluation
- Calculation of material assessments.
- Calculation of priority assessments.
- Advice to building managers and occupiers.
- Reporting requirements.
