What to do if phenol falls on skin?

Is phenol a poison?
Phenol is a general protoplasmic poison (denatured protein) with corrosive local effects. Phenol derivates are less toxic than pure phenol. The lethal dose is between 3 to 30 g, but may be as little as 1 g. Phenol is well absorbed by inhalation, dermal application, and ingestion.
How poisonous is phenol?

What does phenol do to the heart?
Abstract. The fall of blood-pressure after large doses of phenol is due to depression of the heart muscle and dilatation of the blood vessels. With small doses the increase of blood-pressure is due to stimulation of the heart muscle or of the vaso-motor center.
How long does a phenol burn take to heal?
Answer: Phenol burn
