At first, when I watched it, I thought it was absolutely ridiculous that Starfleet engineers built spark and flame generators into the Discovery's bridge, but thinking about it, given that you have inertial dampers and other things that minimize or completely eliminate the physical feeling you would receive from the ship receiving damage, having visceral feedback mechanisms that are not themselves all that inherently dangerous to give more physical cues to the ship taking damage actually makes sense. At least, that's my head canon I'm choosing to go with.
