"How Safe Is Hydrogen?
Mirai’s hydrogen fuel tanks have been rigorously tested and proven to meet 
Global Technical Regulation No. 13. * If the hydrogen sensors detect a 
leak or a collision, the hydrogen tank valves will automatically close to 
prevent more hydrogen from escaping while any hydrogen that is leaked will 
safely return to the atmosphere."

That doesn't address the integrity of the composite fuel tanks.

Amend1e.pdf

That's a definite tl;dr document but as far as I got it seemed to 
recommend controlled leakage before the tanks burst and tried to determine 
the number of cycles before problems occur. However one paragraph was a 
disclaimer saying they don't have enough real world data to be sure.
