Is 1 shot of 95% alcohol safe?

Hi, my friend has offered to pay me $200 to take one shot of some 1410 spirytus which is 95% alcohol content. Now I am wondering would I blackout instantly or would this do serious harm to my body because I feel like 1 shot should be possible but I am just a little nervous. He was saying I have to have some breathing techniques or something or I will black out for sure, anyone know anything about this? I have a pretty high tolerance I think, I weigh 190lbs at 6’5 and I’ve drank pretty heavy before with 47% (like 8 shots or so) but that’s the highest I’ve gone.
