Task description & scope:
This procedure applies where holes need to be drilling in asbestos cement, decorative coatings, bitumen
products containing asbestos, floor tiles and other bonded asbestos containing materials. This covers vertical
surfaces and horizontal surfaces.
This SOP is not suitable for drilling holes in friable Low density Board.
PPE : Minimum requirements - * Indicates standard                           Washable safety boots( laced boots
                                for all ACM minor work                       can be difficult to decontaminate)
 * Half face respirator fitted with a P2 air filter approved to AS         Gloves to afford some protectiion
   1715/1716                                                                 against cuts, abrasion and skin
 * 100% synthetic disposable type coveralls meeting                         contact
    specification that prevents fibre of diameter down to 0.5 microns       * Safety Glasses
    and a maximum of 15 peneetrations of asbestos fibres eg: Tyvek
Training and Certification
Only carry out this work if you have General Asbestos Awareness training and/or specific asbestos work
procedure training relative to this task.
Exposure to airborne asbestos fibres may cause dose related asbestos diseases such as lung cancer;
mesothelioma; or pleural plaques if inhaled in sufficent quantities.
As a first priority, planning for the maintenance of ACM must include consideration of the removal of hte ACM
as the most preferred control option. Where removed , asbestos products must be replaced with non –
asbestos product.
Removal of asbestos products must be done in accordance with the QUT AMMP; Safe Work Australia (SWA)
Code of Practice for the Safe Removal of Asbestos [NOHSC:2002(2005)].
Further advice may be sought from your supervisor, FM Maintenance Manager or FM Health and Safety on
specific safety concerns
Prevent spread of asbestos fibres ( dust) from contaminating surrounding work areas. Ensure all ACM waste
is disposed of correctly as per AMMP.
The responsible supervisor MUST ensure that all personnel are trained and competent in these procedures.
Work site area must be left in a clean and safe condition.
Equipment required in addition to normal tools or             Hand drill or Battery Drill – power set at

 Sturdy foam or thin plastic cup or similar for work on      Suitable asbestos waste container (eg-
     overhead surfaces only.                                     labelled 200 micron asbestos waste bag
 Type H Vacuum cleaner;                                      Appropriate task lighting
