A long time ago I did some work on a hydrated lime spill at a Tarmac operation.
I put in, what I thought was a crazy price (at the time it was!) to get the work. £500.00 per day, per man.
We had Tyvex suit, eye defence, gloves and everything necessary apart from the mouth defence.
We used the paper mouth covers - big mistake.
When hydrated lime picks up any moisture it turns to acid and it will and did burn on every surface it got on that got wet. We sweated profusely in the suits and round the neck and wrists the lime got through, Wow that stuff can burn.
I obviously breathed a great deal in and although I would say that it hasn't affected my life I have lost 25% of my lung capacity and wease a lot of the time.
Never ever compromise on PPE. The £500.00 per day we found out should have been several thousand pounds per day to deal with the spillage properly.
Good luck
