Characters can immediately yell at you to stop straying into globadier gas even if you didn’t take any damage from it and was close to it for just a split second. Gas voice lines can also get interrupted, which doesn’t give a cooldown to it, resulting in repeated voice line spam. I’ve had Victor tell me to “Stop straying into the gas!” 4 times in a row, because the voice lines kept getting interrupted by abilities and what have you. Both of these issues cause them to nonsensically get spammed.
Those voice lines should only fire if you’ve spent several seconds in gas, and have taken at least a couple ticks of damage. And should they get interrupted, it should incur a cooldown like normal.
