If the laser is not operating in the tunnel or if you never enter the laser hazard zone, no- no additional training required.
Course AD103 (FACET Tunnel Hazards) is sufficient.
There is no hazard associated with the laser if it is not getting transported to the tunnel. And if it is getting transported to the tunnel, the hazard only exists in the laser hazard area.
But what if you need to be in the laser hazard zone when the laser is operating? Generally speaking this is never the case! The only people who need to be in the laser hazard zone are qualified laser operators.
If you think you ought to be a qualified laser operator, discuss this with your supervisor and the SLSO (Sebastien Corde).
