Asbestos Management Services Brochure

ASBESTOS SURVEY AND REMOVALSince expanding our service range toinclude asbestos surveying and removal in1999, Sureclean has built up a large team ofoperatives, supervisors and management, alltrained by industry association specialists toprovide asbestos management services.Surveys and Bulk SamplingOur team is fully qualified to undertakebuilding surveys and bulk sampling in orderto locate asbestos still present withinbuildings, factories and installations. On aproject-by-project basis the best course ofaction is determined, based on the conditionand location of the asbestos and other localconsiderations. Dependent on the projectthere are several alternatives - it may be thatthe asbestos is safest left in placeundisturbed, or it may be necessary toencapsulate the asbestos using non-asbestosmaterial, or it may be determined that thebest course of action is to carry out acontrolled asbestos removal.Asbestos RemovalWhen removal is deemed the best option weuse the most appropriate stripping techniqueor a combination of techniques to minimiseasbestos fibre release, taking into account thetype of material containing the asbestos, theconditions and control of the work area andthe ultimate disposal of the debris.The most advanced environmenta lmonitoring equipment, wetting techniquesand decontamination facilities are selectedon a project-by-project basis to ensure thatthe asbestos is removed in a safe andefficient manner.Carrier’s LicenceIn addition to our survey andremoval capabilities, Surecleanholds a Carrier’s Licence andWaste Management Licencewhich enables the stripped asbestos to betransported to our Alness Transfer Station ordirectly to the ultimate disposal site asappropriate.Sureclean provides a turnkey asbestosmanagement and handling service whichcan, in a single operation, solve the problemof locating asbestos and ensuring its safemanagement thereafter.Asbestos survey and removalAsbestos surveying and removal are specialist serviceswhich demand the highest standards of operation andprocedural control. Our philosophy is not only to complywith the onerous legislation pertaining to working withasbestos, but to exceed these requirements.ASBESTOS SURVEY AND REMOVALSmoke Generators (illustrated bottom-centre overleaf)Powerful hand-held smoke machines used toprove the integrity of enclosures prior tocommencing asbestos removal activities.Proprietary chemicals held within a canisterreact when heated to emit a form of smokethat is non-toxic and non-hazardous.
