Additional requirements for licensedasbestos removal304. The laundering facility needs be constructed of smooth surfaces that are ableto be lined with polythene sheeting. Procedures need to be established forcleaning up spills. Flooding of neighbouring areas needs to be prevented.Laundering must be carried out in a manner that eliminates, so far as isreasonably practicable, the release of airborne asbestos fibres. This maybe achieved by placing the laundering room under negative pressure.305. Conventional washing machines may be used provided they are not used forother clothing. The clothing to be laundered should not be allowed to dry outbefore it is washed. Bags of asbestos-contaminated clothing need be openedin the washing machine while being further saturated with water to minimiseairborne dust. As a minimum, P1 respiratory protection needs to be worn whileunloading clothes into the washing machine.306. The containers/bags need to be disposed of as asbestos waste. Waste waterneeds to be filtered and the filtering medium disposed of as asbestos waste.307. Random air monitoring needs to be carried out to confirm employees are notbeing exposed to asbestos.308. Contaminated protective clothing must not be laundered in homes. Referto ‘Division 8 – Activities involving asbestos’ in Part 4.3 of the Regulationsfor specific requirements for the laundering of clothing contaminatedwith asbestos.Planning for removal work from hot surfaces309. If possible, the removal of asbestos from hot metal or machinery needs to bescheduled and planned around shutdowns with sufficient time allowed for themetal/machinery to cool.310. Machinery needs to be cool before removal is attempted. The removal of friableACM from hot metal presents one of the worst conditions for removal becauseairborne asbestos fibres can readily spread on convection currents in the airand the potential for burns is high. In addition, the use of fine water spraysmay not be possible as steam may be created that would make the removaltask more difficult. Hot metal removal can only be performed in emergencysituations. There may be other circumstances under which such removal workmay take place. However, a person competent in heat stress issues needs tobe consulted when making this decision.311. The person who has management and control of the workplace needs to makeevery attempt to arrange for the removal work to be done during periods whensurfaces are not hot.312. In the limited circumstances where the dry removal of ACM from hot surfaces isthe only option (eg emergency situations), particular care needs to be taken inthe selection of dust extraction equipment to cope with the convection currentsinvolved. The selection of appropriate PPE also becomes much more important.313. Heat stress must be considered when preparing the asbestos removal controlplan, particularly in the selection of PPE and the design of the work program(eg sufficient rest breaks and the provision of cool drinking water).54 Compliance code / Removing asbestos in workplaces WorkSafe Victoria
Specificrequirementsfor removal offriable ACMGeneral methods for the removal of friable ACM314. Friable asbestos removal work generally involves establishing an enclosure witha negative pressure exhaust unit and full decontamination unit attached to theenclosure. There are exceptions generally relating to small-scale removal suchas glove bag removals, mini-enclosure removals and wrap and cut removals.315. The methods used to remove ACM must prevent the release of asbestos fibresinto the atmosphere both during and after the removal operation.316. The appropriate removal method will therefore depend on the nature,condition, quantity and location of the ACM and any other health or safetyhazards present.317. Friable ACM needs to be removed using wet methods within an enclosed areaso far as is reasonably practicable. Methods for enclosing large and small-scaleremoval work are described from paragraph 314. In addition:• all ventilation and airconditioning networks servicing the asbestos removalarea need to be closed down for the duration of the asbestos removal workand all vents thoroughly sealed to prevent the entry of airborne asbestosfibres into the duct network• on completion and after final cleaning of the asbestos work area, allmechanical ventilation filters for recirculated air need to be replaced priorto start-up• care needs to be taken to ensure that airborne asbestos fibres cannotescape at points where pipes and conduits pass out of the asbestos workarea (greater attention to sealing and testing is required at these points,particularly if service riser shafts pass through the asbestos removal area).318. The methods and equipment described below are commonly used for theremoval of sprayed asbestos thermal and acoustic insulation from buildingsand structures and the removal of ACM from plant and equipment, includingsteam pipes, boilers and other industrial plant.Large-scale removal workEnclosures319. A licence holder must ensure, so far as is reasonably practicable, the areawhere the asbestos removal work is performed is enclosed so as to preventthe release of airborne asbestos fibres (this area is sometimes referred to asthe ‘bubble’).WorkSafe Victoria Compliance code / Removing asbestos in workplaces 55
