Basis for Recommendation
The Signalman involved in the incident was required remain on duty without having undergone drugs and alcohol testing. There is no specific guidance in HR-QMS-006-005 or IMO-SMS-030 on whether a staff member should be relieved of duty if it is decided that a drugs and alcohol test is required.
Recommendation
IÉ should review their current documents that reference drugs and alcohol testing with a view to clearly addressing how staff should be managed where it has been decided drugs and alcohol testing is required i.e. should staff who are in safety critical roles be stood down until after a negative drugs and alcohol test.
