In my young adult years, I had three car batteries explode on me at work.
One, I was out on the tow truck, jump starting a car in an agricultural setting. I was lucky that the customer who owned the car worked there, knew where a source of running water was from a garden hose located in a nearby barn, and was able to guide me to it. I'm sure it wasn't sterile water, but I'm equally sure it was better than the acid that was at that time etching my eyeballs.
The other two, I was working in the garage at the gas station, so I knew that the nearest source of running water was the chilled water fountain in the corner of the garage. Also not sterile, but also way better than the acid.
I'm fortunate that none of these incidents seem to have permanently damaged my eyes.
Back then, I had never seen or heard of a dedicated eyewash station of any kind, and PPE was not something that was ever even mentioned to me or anyone else I worked with there.
Two of those incidents resulted from broken internal connections in the batteries. The third resulted from an accidental dead-short from +Battery to chassis ground when I inadvertently bumped a wrench from atop a covered fender.
I have taken PPE and safe work practices very seriously in the ensuing decades, after my youthful naivete was gradually supplanted by knowledge.
Reminds me of a story from college... I was deliverering pizza to pay my way through (at least, an apartment, food and basic necessities). One of the other drivers claimed to have been robbed (highly doubtful given the area, but anything's possible). So, I went out and bought a canister of pepper spray, and attached it to my key ring...
...Fast forward a few years, and a girl i started dating said she wanted to "see what the pepper spray smelled like." I repeatedly told her "Don't do that," but she insisted. I told her that she could NOT do it in my room, or anywhere in the house, but needed to go outside. But, please don't try it...
Well, she insisted, and as predicted, came back inside crying and unable to see out of one eye (I didn't go out there with her, so I don't know how she administered the stuff to herself).
So, then it became MY problem to help her out. I'd had enough First Aid training (Eagle Scout) to know she needed to get water into her eye immediately.
She didn't want to do that, no matter how many times I told her. So, I wasted more (of her recovery) time calling 911, who told me to hang up and call the poison control center (I still think that was odd).
Anyway, the poison control center told me that she needed to rinse her eye with... water.
I basically had to hold her head down in the sink and use the sprayer to help her out, she refused to do it herself. It was hard enough to convince her to hold her eye OPEN, or the water wasn't goint to do much. (I also told her the other option was to hop into the shower and stand under the flowing water, but she didn't want to do that, either.)
The water worked, but her eye was red for a day or two.
Needless to say, I threw away the pepper spray (wasn't sure if it would leak once activated the one time), and didn't bother replacing it.
This is the same girl that refused to cook, because she claimed to have set her mother's kitchen curtains on fire, trying to put a flaming paper bag out in the sink, after it caught fire in the microwave (she was trying to DIY microwave popcorn, using just a paper lunch bag). I'd always thought she just made that up to get out of cooking for me, but now I'm starting to wonder, LOL...
We eventually broke up, for a variety of unrelated reasons.

The second story (thankfully) didn't involve eyes, but did involve an exploding car battery, and saline...
One night, I came upon a car, crashed into a guardrail on an offramp, in a rainstorm in June. Called 911, and stayed on the scene (I don't do that anymore, due to a different incident, but that's another story)...
Anyway, police, FD and rescue show up, and block the exit (thankfully, as it was insanely slippery, first rain in over a month). They take the driver back to the rescue (he wasn't hurt, but they always check).
Then they send a rookie fireman (alone) down with a pair of bolt cutters to cut the battery cable. Being the former Boy Scout (and already wet), I figured I'd help by holding a flashlight so he could see what he was doing.
Needless to say, he shorted the wire with the cutters, and the battery exploded, spraying acid everywhere.
Even though he was completely dressed in turnout gear, they took him into the rescue and started throwing sailine at him.
When I mentioned that I'd been sprayed on the arms, they looked at me with disgust, but eventually capitulated and rinsed my arms. Oddly, it never really burned, but I'm sure it would have eventually.
