How do I find out if 2% of Isopropyl Alcohol in a mixture is still considered a dangerous good? There are no other flammable ingredients.

Basically, at what point does it become flammable? We have a few products with 2% ISO, and one with 3% and one with 5%. Need to know if we need to put flammable pictograms on them.

Thank you xoxoxo

I used to estimate by figuring; 70% (alcohol) x some number = 50%. I’d arrive at ~.71 and .~29 for water, and then I’d round it to 70% and 30%.
