certainly not going to the hospital in the event it gets on my skin.
Welcome to TFP.
Just wanted to aleve some scare here.

WARNING .. I have very delicate skin, and have spent my life avoiding products that irritate me.
I've used MA for many things, most of my adult life, with NO problems or issues. I've been a "handy person - girl scout" since I was a tot.

Almost forgot; DH is M.D., I'm RN among other training.
My mother told me (many years into adulthood) that, when I a newborn, the first time she put clothing or blanket, etc., on me, that wasn't cotton and double/triple rinsed I started screaming and instantly broke out in a rash. It's been that way all my life, as far as fabrics, dyes, and perfumes, additives, etc.. Most medical tapes, used on my skin cause open blisters after a few hours. If my dentist, who has the tiniest hands, uses the wrong gloves I come home with fever blisters starting. On and on and on. There are a few fabrics that have worked well, especially with new, sustainable products, like hemp, bamboo, Tencel, etc. Many Rayon fabrics hold dyes well and are easy care but not linen. Thank goodness for Polyester blends, too, for ease of care. Nylon and acrylic torture me.
Many here know that gg can't be "delicate". Mainly it's her skin only. And aging typically makes skin get more and more delicate. I passed over the big 60 last year. Animal teeth and nails tear my skin more easily now than just a few years ago.
I've acid washed my pool three times in 24 years, last time as I was approaching 60. I wear safety goggles, and put heavy baby sunscreen on my face for protection and place several box fans around the pool edge to pull fumes away especially when working in the 10 ft deep end.
See how I dress when acid washing my pool.

As long as I rinse the acid off within a few seconds, 10 or so, I don't even feel much sting. I've never, ever gotten a burn from 3x.x MA AND there's always water around for a quick rinse ........ that's the secret.
Another secrete is to always assume that there will be fumes, and like smoke from a camp fire, it will always "head right in your direction", so check the wind and keep your face as far away from the bottle as possible opening it our using it.
Just my un-humble opinion.
