The fact that nobody was injured in the previous incident is fortunate for anybody who might have been injured then, but doesn't diminish the importance of addressing whatever flaw caused the explosion. Considering that we're talking about a lot of liquid helium being improperly vented, the next time something goes wrong it could end up asphyxiating a hundred people.

Just because nobody was in the danger zone the first time it exploded doesn't mean you should count on nobody being in the danger zone the second or third time it might explode. This is the reason work site safety officers yell at people to report all near-miss incidents, not only the accidents that get people hurt. If something went wrong and nobody got hurt by chance coincidence, it might happen again when people are actually near it. Therefore a near miss incident needs to be addressed with the same seriousness as an accident that actually caused injury.

Even if it doesn't suffocate you, helium leaks can be pretty bad since they'll temporarily brick any modern phone with a MEMS oscillator (like a quartz time crystal, but smaller) in it. Not great if you need assistance.

As far as i know, you shouldn't bring your phone near a MRI machine.
