Yes , its considered extremely caustic for human consumption. Healthy PH level for drinking water is somewhere around 7.2 to 7.4 Inhaling Acidic or caustic moisture could really hurt your lungs tissue . It's not worth it to chance for me. Only reason I am chiming on this thread is I really don't want anyone hurt or sick . There is big health risks if you don't know what your doing on this subject. stay healthy
