caustic attacks any body tissue upon contact. the degree of injury depends upon
the extent and duration of contact and the temperature and concentration of the caustic.
its corrosive action on tissues causes burns and frequently deep ulcerations.
its contact with the eyes rapidly causes severe damage.
caustic solution is detectable by a slippery feeling like soapy water.
