Material Safety
Alcian blue is an eye and respiratory tract irritant. Solid Alcian blue is a combustible powder and should never be handled close to heat or a naked flame. Heating Alcian blue produces toxic fumes of nitrogen compounds. It can react violently if mixed with oxidising materials. The solution of Alcian blue is a skin sensitiser and corrosive (partly due to the acidic pH needed to maintain it unhydrolyzed in solution) and harmful by skin absorption. Most vendor MSDS (Material safety datasheet) mention that effect of ingestion not known or target organ not known. However some do mention that potential target organs are teeth and kidneys.

Famous quotes containing the words material and/or safety:
“We have imagined ourselves a special creation, set apart from other humans. In the last twentieth century, we see that our poverty is as absolute as that of the poorest nations. We have attempted to deny the human condition in our quest for power after power. It would be well for us to rejoin the human race, to accept our essential poverty as a gift, and to share our material wealth with those in need.”
—Robert Neelly Bellah (20th century)
“An evident principle ... is the principle of justice to all peoples and nationalities, and their right to live on equal terms of liberty and safety with one another, whether they be strong or weak.”
—Woodrow Wilson (1856–1924)
