Rail Drug and Alcohol For-Cause Testing Nationwide
Richfield Occupational Health Solutions Limited provides nationwide rail drug and alcohol for-cause testing, supporting infrastructure providers, principal contractors and rail operators.
For-cause testing is typically undertaken following:
-
Safety-critical incidents
-
Near misses
-
Accidents
-
Suspected impairment
-
Policy-triggered events
We understand the urgency and sensitivity surrounding post-incident testing and operate with professionalism and discretion.

What Is For-Cause Testing?
For-cause testing is initiated when there is reasonable suspicion or following a defined incident under company or rail industry policy.
It is distinct from random testing and is often required immediately following an event.
Timely, compliant testing is critical in maintaining safety standards and protecting organisational integrity.
