explosion proof boroscopes...?

[jettison valve]

Good evening,

does any of you have an explosion proof boroscope/flexiscope/videoscope? If yes: Where can I get it from...!?

We need to inspect something in the A330/A340 Trim Tank during maintenance - but as the tank cannot be considered non-hazardous then, we need that sort of special equipment...

Any help?

Cheers,
J.V.
