Yes. PH level 14 is Toxic to humans. But substances like drain cleaner have a PH of 14
A normal or neutral pH level is 7. Caustic soda is highly basic with a pH of between 13.5 and 15. Caustic soda is a dangerous base and should be handled carefully.
Depends what the substance is! Yes, a pH of 13 is VERY high. Depending on the substance, it can be safe to touch (such as bleach), but probably not to drink. There is more to consider than pH when deciding whether something is dangerous, though.
According to Proctor and Gamble in 2002, the pH level of Tide is around 10-11. In the "dangerous" category... The safest category for human skin is from 5-9.

6.5 pH is too low pH for the blood. It is dangerous. You have got acidosis. The physician will take prompt action. The same pH in the stomach is too high. It is not dangerous. But it may hamper proper digestion of the food.
