1 ASBESTOS AWARENESS Steve Adamthwaite PEHO City of York Council
2 ASBESTOS AWARENESS WHAT IS ASBESTOS? WHERE DOES IT COME FROM? WHY IS ASBESTOS CONSIDERED TO BE POTENTIALLY DANGEROUS? WHERE COULD WE POSSIBLY FIND IT IN BUILDINGS?
3 What is asbestos? Derived from Greek word --- unquenchable, unscathed by fire Based on silicates formed from oxygen and silicon
4 ASBESTOS Chrysotile - Serpentine Amosite - Amphiboles Crocidolite Anthophylite Tremolite Actinolite
5 ASBESTOS RELATED DISEASES Asbestosis Mesothelioma Bronchial cancer Pneumoconiosis
6 Examples of asbestos in buildings
7 Asbestos Applications Sprayed Coating Lagging Insulation Board Ropes and Yarns Cloth Millboard Paper Asbestos Cement
8 Asbestos Applications Asbestos Bitumen Products Flooring Materials Textured Coatings and Paints Mastic Sealants, Putties and adhesives Wall Plugging Compounds Domestic Appliances
9 Commercial Buildings Pre Chrysotile Lagging Asbestos Cement Sheeting 1939 Chrysotile Lagging and Asbestos Cement Sheeting 1980 Chrysotile lagging,sheeting Preformed Lagging, Amosite Partitioning, Ceiling tiles and Amphibole sprayed coating
10 Commercial Buildings Present Very little asbestos used in new buildings, some asbestos cement sheeting used externally 1999 All forms of asbestos banned
11 Sprayed Coating Use Content Remarks Thermal and acoustic insulation and fire and condensation protection products 85% in hydrated asbestos cement.crocidolite amosite and chrysotile used Extremely friable.high potential for fibre release.increases as material ages
12 Sprayed Coating Remarks Repair and removal must be carried out by licenced contractor. Found on structural framwork and the ceilings of swimming pools and as fire breaks in ceiling voids
13 Sprayed asbestos
14 Sprayed asbestos
17 LAGGING Use Content Remarks Thermal insulation of pipes, boilers,calorifiers.preformed pipe sections,corrugated paper, quilts,felts, blankets Variable.Can be up to 100% in blankets, felts Potential for fibre release unless sealed.
18 Lagging Remarks Widely used in public buildings.on pipework. Can contain all types of asbestos.don t t go by colour
21 INSULATION BOARD Use Content Remarks Fire Protection, thermal & acoustic insulation Amosite,chrysotile and in boards before 1965, Crocidolite Trade Names Asbestolux, Marinite Likely to give rise to high levels of fibre if worked or removed.
22 Asbestos insulating board
24 Ropes & Yarns Use Lagging,jointing,packing,gaskets, boiler and flue sealing Content 100%.All types prior to 1970, since then only chrysotile Remarks Fibre may be released when large quantities of unbonded material are handled.
25 Cloth Use Content Jointing & packing.thermal insulation.fire blankets,gloves etc 100%.All types mostly chrysotile Remarks Fibres may be released if material is abraided or frayed
26 Asbestos textiles
28 PAPER Use Content Remarks General heat insulation and fire protection.electrical and heat insulation.vinyl flooring.corrugated pipe insulation 100%.All types.chrysotile after 1965 Uncoated products liable to release fibres on abrasion or wear can be a hazard when handled.
29 Asbestos Cement Use Profiled sheets,roofing,wall cladding.bath panels, soffits,rain water goods Content All types crocidolite amosite Mainly Chrysotile Remarks Fibres firmly bound and only released if mechanically damaged
30 Asbestos cement
31 ASBESTOS CEMENT A Material which is predominantly a mixture of chrysotile and which when in a dry state absorbs less than 30% water by weight Work with asbestos cement in most cases will not require a licence
34 Asbestos Bitumen Products Use Roofing felts, damp proof products Content Remarks Chrysotile fibre or asbestos paper 100% Fibre release unlikely in normal conditions.should not be burnt after removal
35 Flooring Materials Use Content Remarks Floor tiles and backing for PVC flooring Thermoplastic floor tiles up to 25% Fibre release unlikely under normal conditions.any residue sticking to floor after removal should be lifted off when damp
36 Textured Coatings and Paints Use Coatings on walls and ceilings Artex Content 3-5% Chrysotile Remarks Potential for fibre release when old coatings are rubbed down
37 Wall Plugging Compounds Use Wall fixings Philiplug Content >90%
38 Reinforced Plastics Use Content Remarks PVC panels and cladding for domestic goods Mostly Chrysotile Unlikely to release fibres during use but cutting with power tools should be avoided
39 Domestic Appliances Use A variety of appliances for heat insulation Hairdriers,fan and radiant electric heaters washing machines cookers, simmering mats
40 CONTROL OF ASBESTOS REGULATIONS 2006
41 ACTION LEVELS/CONTROL LIMITS No action levels. No differentiation between asbestos types Single control limit (0.1f/cu.cm) 10minute STEL (0.6f/cu.cm) ACOP Control limit not to be exceeded if measured over 4hrs
42 LICENSED WORK No longer linked to form of ACM Textured Decorative Coatings excluded Linked to exposure NOT being of sporadic and low intensity AND The RA concluding the STEL will not be exceeded. Extended to employer using own employees on own premises
43 TEXTURED COATINGS Risks much lower than previously considered. Risks lower than AC Proper control measures still required ACOP
44 RPE Needs to be worn irrespective of fibre levels. Aim to reduce exposure level to ALARP not simply below the Control Limit.
45 Duty to manage asbestos
46 Duty Holders Wide range of people have duties under these regulations including employees and self employed Extent of practical duties determined by contractual and other existing legal obligations towards the property
47 Control of Asbestos at Work Regns 2006 Require duty holders to: Take reasonable steps to find materials in premises likely to contain asbestos and to check their condition Presume that materials contain asbestos unless there is strong evidence to suppose they do not
48 Duty holders will have to: Find out if there is asbestos, how much, its condition and where. Presume unknown materials are ACMs. Make and keep an up-to to-date record of the location and condition of ACMs/presumed ACMs. Assess the risks from ACMs.
49 Control of Asbestos at work Regulations Make a written record of the location and condition of asbestos and presumed asbestos-containing materials (ACM s) and keep the record up to date (Asbestos Register) Assess the risk of the likelihood of anyone being exposed to these materials
50 Control of Asbestos at Work Regulations 2006 Prepare a plan to manage that risk and put into effect to ensure that: Any material known or presumed to contain asbestos is kept in a good state of repair Any material that contains or is presumed to contain asbestos is, because of the risks associated with its location or condition, repaired or if necessary, removed Information on the location and condition of the material is given to anyone potentially at risk
51 The Asbestos Register What should it contain? The Exact location of the asbestos Identifying features The form the material takes Whether the material is confirmed or suspected as asbestos The quantity present The condition of the material
52 What if I can t get everywhere to inspect?
53 Concealed or inaccessible locations The register must state whether these areas have been inspected to contain asbestos or whether that presence is assumed
54 What has to be done and how Delegate the task although the ACOP refers to duty holder someone else can be nominated to do all or part of the work Finding ACMs and assessing their condition Assessing the risk from ACM s Managing the risk and preparing the plan
55 Managing the risk and preparing the plan Where asbestos is present or liable to be present duty holder shall ensure that- A written plan identifying those parts of the premises is prepared The measures which are to be taken for managing the risk are specified in the written plan which shall include that any such substance is properly maintained or where necessary safely removed
56 Monitoring Arrangements Measures for managing the risk shall include measures for: Monitoring the condition of ACMs Review of the plan at regular intervals and forthwith if there is reason to suspect that the plan is no longer valid or there has been a significant change in the premises
