IMPORTANT INFORMATION
1.1 SURVEY DETAILS
Re-inspection survey
A visual Re-inspection of asbestos containing materials previously identified at ALE, New Road, Hixon,
Staffordshire. Supplement to report No’s 1126 01919, and 02104.
The re-inspection included material assessment of all previously identified asbestos items in
accordance with Regulation 4 of the Control of Asbestos Regulations 2012
Inaccessible area/reasons for no access:-
N/A
Reservations and Concerns:Extensive Asbestos cement debris was identified to the permitter were the original Storage Hut 2 was
located. Material now requires removal

Report No. 2319
1.2 BRIEF
Re-Inspection Survey:
The purpose of a re-inspection is to locate as far as reasonably practicable; Asbestos Containing Materials
identified within the original survey to assess their condition and update the site register.
This re-inspection is produced directly from the original survey report. Any information such as clearance
certificates should also be retained along with the report, to give confirmation of any asbestos removal and its
scope. Where no such confirmation exists at the time of re-inspection, it may be presumed that the asbestos
containing material remains.
Areas not accessed during the original survey will generally be omitted from the re-inspection and must be
presumed to contain asbestos until confirmed otherwise.
The survey findings have been compiled into a register format that includes photographs and plans showing
sample locations. All samples of asbestos materials taken during the original survey are numbered with the
original report number to identify their origin. Where additional samples are taken as part of the re-inspection,
these will normally be numbered with the re-inspection report number
.

Report No. 2319
1.4 MATERIAL RISK ASSESSMENT
A risk assessment incorporates a scoring system for each asbestos item relating to its potential for fibre
release. This provides a simple and effective method by which priorities for action can be assigned.
Points are accumulated according to the product type, extent of damage, surface treatment and asbestos
type.
The risk assessment code ranges between 2 and 12 with:-
V-Low = 2 - 4
Low = 5 - 6
Medium = 7 - 9
High = 10 - 12
The material risk assessment identifies asbestos containing materials most likely to release fibres into the air,
and will give a good initial guide to the priority for management.
Management priority however must be determined by undertaking a priority assessment in addition to the
material assessment. This will determine the likelihood of the asbestos containing materials being disturbed
by taking into account maintenance activities, human exposure potential, likelihood of disturbance and
occupant activity.
The combined risk assessments are then to be used to form a management plan in accordance with the HSE
Management of Asbestos Containing Materials Regulations.
'High' Risk Category
Materials in the 'high' category require urgent consideration. Factors to be taken into account include future
use of the building, company policy and available finance. The following options may be appropriate:1)
Complete removal.
2)
Encapsulation, sealing or other protection including marking with appropriate warning labels.
3)
Decontamination works.
4)
Close monitoring of condition and potential for persons to be exposed to airborne asbestos fibres.
(This may involve air sampling adjacent to the material to determine whether airborne asbestos fibres
are being produced).
'Medium' risk category
The condition of any material in the 'medium' category requires regular monitoring and a programme of
encapsulation or removal may well be appropriate in the medium to long term.
'Low' risk category
'Low' risk category materials are generally not considered to cause any immediate concern and are unlikely to
present any significant risk under reasonably foreseeable circumstances. Periodic condition monitoring is
however advisable.
'Very Low' risk category
'Very Low' risk category materials are generally of a cement, resin or plastic based material and are not
considered to cause any immediate concern, as these are unlikely to present any significant risk under
reasonably foreseeable circumstances. Periodic condition monitoring is however advisable.

1.5 SUMMARY
When a summary of the asbestos samples taken is included in a survey report it is located in Appendix A.
This summary must be read in conjunction with the test reports to categorically determine the extent of the
Asbestos Containing Materials present in this building. The summary in Appendix A is of sample locations
only. This report must be read in its entirety.
Each sample containing asbestos, identified within the survey, has been given a recommendation based on
the surveyor’s assessment of that material.
1.6 REVIEW OF REGISTER
It is normal practice to review all asbestos registers on an annual basis or more frequently where there is
potential for rapid deterioration. This involves re-evaluating all risk assessment codes during a 'walk around'
inspection then amending the register accordingly.

1.8 REMOVAL AND WORKING WITH ASBESTOS CONTAINING MATERIALS STATUTORY REQUIREMENTS
This short summary is intended to provide an overview of legal requirements and is not comprehensive. The relevant
statutes, statutory instruments and official publications should be consulted as necessary.
Legislation
The Control of Asbestos Regulations 2012 places numerous obligations on persons removing, working with or
disturbing asbestos containing materials. The Regulations cover the following main areas:•
•
•
•
Licensing of contractors for work with most asbestos containing materials
Working procedures and methods
Management of asbestos which is left in situ
Prohibitions on the use and re-use of materials containing asbestos
Further practical information is then given in two Health and Safety Commission Approved Codes of Practice – Work
with Materials Containing Asbestos, L143 and The Management of Asbestos in Non-domestic Premise, L127.
In addition to the above asbestos specific regulations it is important to appreciate that other safety related legislation
may be relevant in some circumstances. For example The Health and Safety at Work etc Act 1974 places general
duties on employers and persons in control of premises to ensure the health and safety of employees and others. The
Management of Health and Safety at Work Regulations 1999 obliges employers assess risks from work activities
(including potential exposure to asbestos) and The Construction (Design and Management) Regulations 2015 place a
range of safety related duties on clients, planning co-ordinators and principal contractors.
Work Which Requires an HSE Asbestos Licence
Most work with asbestos containing materials may only be carried out by a specialist contractor licensed by the Health
and Safety Executive under Regulation 8. The only exception is where the work is extremely low risk (ie when worker
exposure is below 0.6 fibres of asbestos per millilitre of air over any 10 minute period, below the 4 hour Control Limit
of 0.1 fibres of asbestos per millilitre of air and is restricted to work on bonded materials or consists of resealing of
asbestos containing materials that are already well sealed).
Working Procedures and Methods
There is no known safe level of exposure to asbestos, therefore very detailed and onerous working procedures have
been published by the Health and Safety Executive – see Asbestos: The Licensed Contractors Guide, HSG247 and
Asbestos Essentials, HSG210.
Work on inherently friable (dust producing) asbestos materials requires full enclosure with negative differential
pressure produced by air extraction plant equipped with high efficiency filtration. Entry to the working area is by an
airlock system and on site personal decontamination facilities must be provided. Workers must be subject to medical
surveillance and receive detailed certified training.
Work for which an asbestos licence is required must be notified to the enforcing authority at least 14 days before
commencement on form ASB5 and upon completion it is necessary to obtain a Certificate of Reoccupation from an
independent testing laboratory. The issuing laboratory is required to hold accreditation from the United Kingdom
Accreditation Service (UKAS) for the certification procedure.
Procedures for work on bonded materials do not necessarily require full enclosure but this must be fully justified in the
written assessment and plan of work which should be prepared before the work starts.
Page 9
Report No. 2319
Waste Disposal
Virtually all materials which contain asbestos are classified as ‘hazardous’. This includes asbestos cement, asbestos
vinyl floor tiles etc. Transport from the site requires pre-notification to the Environment Agency and wastes may only
be deposited at specially licensed disposal sites.
Using Unlicensed Contractors for Work with Low Risk Materials
As described above it is occasionally permissible to use non licensed contractors, such as general builders or
demolition contractors, to work on low risk asbestos containing materials. Griffin Environmental would strongly advise
against this approach as the other provisions such as non specialists are unlikely to produce the necessary
documentation such as exposure assessments and waste consignment forms, they will not have appropriate
equipment and their operatives are unlikely to have received the training required by Regulation 10.
It is also important that adequate insurances are in place for work with asbestos which are generally not available to
un-licensed companies and without which a client will be in difficulty should a claim arise against the contractor.
MANAGING ASBESTOS CONTAINING MATERIALS LEFT IN SITU
It is permissible to leave asbestos containing materials in-situ in appropriate circumstances providing that the risks are
properly managed. The Approved Code of Practice, L127 and The Comprehensive Guide to Managing Asbestos in
Premises, HSG227 provide much useful information including the development of an asbestos management plan.
Retained asbestos materials must also be regularly re-inspected to confirm that their condition has not deteriorated.
Comprehensive records should be retained for inspection by enforcement inspectors.
Further Information and Assistance from Griffin Environmental
The proper management of asbestos is highly complex and failure to adequately control risk can lead to asbestos
related disease, reduced property values or result in enforcement action. Griffin Environmental is always pleased to
provide information and assistance for comprehensive asbestos removal and asbestos management services.

1.9 CAVEAT
Every reasonable effort has been made to ensure that the information contained in this report is as accurate
and as comprehensive as was practicable at the time of preparation. However due to the nature of asbestos
survey techniques, it is not reasonably practicable to categorically state whether all asbestos containing
materials were identified.
Certain asbestos products contain asbestos fibres that are so well bound into the matrix of the parent material
that they do not readily generate respirable asbestos fibres under reasonably foreseeable circumstances.
Examples of such materials include sealing mastics, rubber gaskets, bitumen patches and damp proof
membranes. All such materials have therefore been excluded from the report.
Certain ‘Artex’ type textured coatings and decorative plasters may contain very small quantities of asbestos.
In situ these coatings are often composed of different batches of product or may have been repaired/patched
at different times. It is therefore possible that any ‘Artex’ samples taken may not be representative of the
entire coating. Recent research suggests that in some cases, the fibres may have diameters below 0.1µm.
These may not be visible by the optical microscopy method described in HSE publication HSG 248 (2005).
Where asbestos containing materials were installed during construction it is possible that unidentified
contamination may exist within or below other components, for example below floor screeds. It is also
possible that unidentified asbestos residues resulting from earlier asbestos removal works may be present in
relatively inaccessible locations e.g., behind claddings, plant services or fixtures and fittings. Where such
residues are found, these may be more extensive than those identified, due to previously mentioned areas of
restricted access or due to paint finishes etc., encapsulating the residues.
Access to electrical and process equipment was not possible due to safety and technical considerations.
Such items may therefore contain unidentified asbestos materials or components. We would be pleased to
make appropriate arrangements to complete the inspection if required but would require your authority to
isolate or dismantle the relevant items using competent tradesmen where necessary.
Griffin Environmental cannot therefore accept liability for loss, injury, damage or penalty caused by omissions
or errors contained in this report. The report does not waive the responsibility of the building owner,
contractor etc. to ascertain for himself as to the composition of materials which may be disturbed or with which
he may work.
Fuel burning boilers and associated flues were not dismantled or sampled for safety reasons. Where samples
are required of these, qualified engineers are to be provided by yourselves to isolate or dismantle the relevant
components.
Any areas not accessed during the survey are to be presumed to contain asbestos until proved otherwise.
