How do I remove a false positive breathalyser result site block


Occasionally, breathalyser equipment on site can record a false positive breathalyser result and a site block will automatically be applied to the cardholder.  This situation needs to be managed as per the Contractor In Charge's Drug and Alcohol Management Plan (DAMP) and appropriate information and documentation provided to the RIW Service Desk for removal of the site block if appropriate.


It is important that the Contractor In Charge provides evidence and authorisation to the RIW Service Desk that their DAMP has been applied in the decision making process to remove the site block.




This instruction applies to the following RIW System User Roles:

Step 1: Establish the non-negative result

The Contractor In Charge (CIC) needs to be satisfied that the breathalyser result is a non-negative result.


Step 2: Refer to the DAMP for secondary confirmation testing requirements

The CIC is to refer to their DAMP to confirm the procedure on how to conduct a secondary confirmation test to contradict/affirm the primary result.


The DAMP may outline that one of the following conditions are part of the confirmation testing requirements:

  • Testing has to be conducted by a third party company
  • Confirmation of the secondary test is to be documented with the result confirmed
  • Other conditions or protocols


Step 3: Conduct secondary confirmation testing and collect evidence

Conduct the secondary confirmation test and capture the evidence of the test. If the test proves that the primary test was a non-negative, proceed to Step 4.


Step 4: Raise a Service Request

Raise a ticket with the RIW Service Desk by sending an email to info@riw.net.au with the cardholder details, site, and reason for removal of the site block.  This request has to explicitly state that the person providing the request has authorisation to remove the site block as per the CIC's DAMP.  Documentation supporting the authorisation is required to be attached to the email.



Removing site blocks has safety risks and is only performed by the RIW Service Desk once the appropriate authorisations and evidence for the removal have been received.
