The real question is; why would one work actively in a chemistry lab without gloves? However if the question needs to be answered, I would say pH of 6, 7, and 8 would be save; per experience.

Does anyone have a rule of thumb for how high pH can go before gloves are required?

Thanks for any help with this.
