Network Rail Drug and Alcohol Testing

Crystal Health Group is an approved and audited supplier to Network Rail for the provision of drug and alcohol testing. View the certificate here.

The company maintains this important accreditation through the official Achilles audit process. Drug and alcohol tests are performed for Network Rail and its subcontractors and uploaded to the Sentinel system. We offer both Pre-appointment (Pre-employment) drug testing, random drug and alcohol testing and periodic testing for organisations and contractors. At this time, we are unable to provide drug and alcohol testing ‘For Cause’ situations.

The official definition of the RISQS drug and alcohol testing accreditation is as follows:

RISQS supports Network Rail, LUL/Transport for London, passenger, light rail and freight train operators, rolling stock organisations, main infrastructure contractors and other rail products and services providers in the management of supply chain risk. RISQS is an independent, third party qualification assessment of a supplier’s capability to supply products and services.

In addition, Crystal Health Group can provide ‘Rail Standard’ Drug and Alcohol testing for non-Sentinel purposes. For example, this could be for Euro Star rail services that do not fall under Network Rail jurisdiction.

As required, the following drug groups are tested using the Urine Laboratory Screen and Confirmation Drug and Alcohol Test for all Network Rail tests:

  • Amphetamines
  • Benzodiazepines
  • Cannabis
  • Cocaine
  • Methadone
  • Opiates
  • Propoxyphene
  • MDMA (Ecstasy)

Alcohol is screened for using a Home Office approved Breath Alcohol device as required by Network Rail protocols.
