Submitting a sample to our laboratory
-
Preparation for taking a sample
· Make sure no one else is in the vicinity when sampling is done.
· Shut down any heating or cooling systems to minimise the spread of any released fibres.
· Turn off any fans if you’re inside. If outside, then sample on a non-windy day.
· Do not disturb the material any more than is needed to take a small sample.
· Collect the equipment you will need for sampling, including:
· pliers, resealable plastic bags, disposable coveralls, waterproof sealant, plastic drop sheet, water spray bottle, labelled heavy duty plastic (200 µm polyethylene) asbestos waste disposal bags
· P2 respirator, rubber gloves.

Taking a sample
· Wear disposable gloves.
· Put on respiratory protective equipment (RPE).
· Wear a pair of disposable coveralls.
· Lay down a plastic drop sheet to catch any loose material that may fall off while sampling.
· Wet the material using a fine mist of water containing a few drops of detergent before taking the sample (generic handheld spray bottle is suitable). The water/detergent mist will reduce the release of asbestos fibres.
· Carefully cut a thumbnail/10 Cent piece size sample from the entire depth of the material using the pliers.
· For fibre cement sheeting, if possible, take the sample from a corner edge or along an existing hole or crack.
· Place the small piece into the resealable ziplock bag.
· Double bag the sample in another resealable ziplock bag, on the exterior of the sample bag write the date, sample number, location and an asbestos caution warning.
· Tightly seal the container after the sample is in it.
· Use a damp paper towel or disposable rag to clean up any material on the outside of the container or around the area sampled.
· Check the surrounding area for any debris as a result of sampling, wipe/clean any residual debris with the disposable cleaning cloth/paper towel.
· Patch the sampled area with a plaster based gap filler. However, if the material is to be immediately removed/handled by a licensed contractor post-sampling, a small piece of duct tape may be placed over the sampling area to prevent fibre release during the interim rather than applying gap filler.

Post-sampling cleanup
· Seal the edges with waterproof sealant where the sample was taken.
· Carefully wrap up the plastic drop sheet with adhesive (cloth or duct) tape and then put this into a labelled heavy duty plastic asbestos waste disposal bag.
· Wipe down the tools and equipment with a disposable dampened cloth or paper towel.
· Place disposable gloves and coveralls into labelled heavy duty plastic asbestos waste disposal bag, along with the used disposable cloth/paper towels and drop sheet.
· Seal the plastic bag and then place it in another labelled heavy duty plastic asbestos waste disposal bag (i.e. double bag).
· Wash hands.
· Continue to wear the RPE until the clean-up is completed.
· Follow a decontamination procedure (personal washing) and wash non-disposable RPE upon completion of the task (if applicable).
· Store non-disposable RPE in a sealed and labelled container. If disposable RPE was utilised place the used RPE in the asbestos waste bag with other used sampling materials.
· Dispose of asbestos materials according to state or territory and local procedures. Consult your local council website for clear directives.
