First of all if you spill it on youre favorite shirt the muriatic acid will knock holes on it. If you spill it on youre hand it's ok as long as you dilute it ASAP by saying Asap i really mean it. because if you don't you'll get burned in a really really bad way. The fumes are also dangerous and if you ever you accidentaly drink muriatic acid youre guts would probably dissolve so yeah muriatic acid is dangerous if it came in contact with our body
