Compliance sampling - assessment of the suitability of respirator protection Please note that it is a requirement of CAWR2006 that all air monitoring for the presence of airborne asbestos fibres is undertaken by an accredited laboratory to ISO/IEC 17025.

Identification of Asbestos Material (Bulk Sample Analysis)
The company has facilities to undertake asbestos bulk samples analysis at the Main Laboratory based at head office or from specified satellite laboratory site set-ups that meets the quality objectives and requirements of the Health and Safety Executives "Methods for the Determination of Hazardous Substances 77" Asbestos in bulk materials (MDHS 77), HSG 248 , the International Standard ISO/IEC 17020, UKAS and current legislation. To meet the quality objectives and requirements of the standard, Spectra has attained accreditation by the United Kingdom Accreditation Services ( Accreditation Number 2621) for asbestos bulk sample analysis at the main laboratory. Normal turnaround for analysis of bulk materials from the time samples are received at our laboratory is within 24 to 48 hours (exclusive of bank holidays and weekends) depending on the number of samples. However when urgent analysis of sample batch is required, special arrangements can be negotiated for immediate turnaround depending on number of samples and availability of staff.

Asbestos Surveys and Registers

Spectra Analysis Services Ltd is accredited by UKAS to ISO/IEC 17020 for each of the two types of asbestos surveys detailed in HSG 264 as described below:

Management Surveys
A standard survey, formally known as a type 1 or with sampling type 2 survey , the purpose of which is to locate as far as is reasonably practicable, the presence and extent of any suspect asbestos containing materials in the property/building etc . Further taking into consideration the likelihood of damage or disturbance during normal occupancy or future maintenance works, as well as maintaining an ongoing management plan.

Refurbishment and Demolition Survey
Formally known as a type 3 survey, as  discussed in detail below in our recent overview paper published on the Asbestos Inspection Bodies website;
Refurbishment and Demolition Surveys have been carried out as ‘Type 3’ surveys since the introduction of
MDHS 100 in July 2001. This document provided advice and methodology for surveyors engaged in all asbestos survey types. However, the guidance for Type 3 Surveys was nominal which inevitably led to varying degrees of inspection procedures by the surveying companies. The Health and Safety Executive have now issued Asbestos: The Survey Guide (HSG264) which was published on January 29th January 2010. The new guidance is specifically aimed at surveyors who carry out asbestos surveys and those who commission the surveys. (Client / Duty Holders) The client / duty holder has been given more guidance in the selection of the inspection body / surveyor and their own responsibilities under the Control of Asbestos Regulations 2006 reinforced. Greater emphasis has been placed on ‘pre-survey communication between the surveyor and the client. The scope and area of the survey must be established and fully understood by both parties prior to commencement of survey procedures. Imposed restrictions from either party must be agreed and documented and caveats should only be included within the report where absolutely necessary and should be fully justified.
It is recognised that the contracted surveyors experience is a vital element in obtaining a successful survey. The surveyor must be more than ‘P402 qualified’ and is required to show sufficient expertise and relevant practical experience. To achieve this standard the HSE strongly recommend the use of accredited inspection bodies or certified surveyors. (UKAS Accreditation ISO 17020 or ISO 17024 respectively) Refurbishment and Demolition surveys are intended for all work that is liable to disturb the fabric of the building. Their intention is to locate all the asbestos materials within building (or area surveyed) as far as reasonably practicable. It is a ‘fully intrusive’ survey and will involve aggressive inspection techniques to gain access to all specified areas including penetration to the fabric of the building. Dependant on the scope of works the surveyor may need specialist equipment or assistance and additional advice may have to be sought from a competent person e.g. Structural Engineer, where brickwork is to be removed or Licensed Asbestos Removal contractor where an asbestos material must be removed to enable access.
Refurbishment / Demolition surveys should only be conducted in unoccupied areas, ideally the building / structure should be vacant and all furnishings removed. For minor survey works this would apply to the room or area to be surveyed only.

Non-accessed areas must be clearly defined within the report to allow the demolition / refurbishment process to be progressive in these areas. It is widely recognised that even with complete access to the area surveyed all asbestos containing materials may not be identified, and will only become apparent during the demolition process. The survey must be carried out in a structured and methodical manner and the final report should be ‘fit for purpose’ comprehensible to, and useable by the client.
