Highly toxic by all routes of exposure. Highly corrosive to skin or eyes; considerable heat evolved when mixing with water. Use a fume cupboard if practicable, otherwise use small quantities in a well-ventilated area. Use eye and skin protection when splashes are possible.
ALWAYS ADD SULFURIC ACID TO WATER, SLOWLY, WITH VIGOROUS STIRRING; evolves toxic fumes on heating. Do not mix concentrated sulfuric acid with potassium permanganate since violently explosive manganese heptoxide is formed, or with chlorate salts since violently unstable chlorine dioxide is produced.
The reaction with sugar produces a large quantity of toxic gases (carbon monoxide and sulfur dioxide), and the voluminous char should be washed thoroughly with water to remove acid before handling. Senior students Years 11-12 may be given small quantities (<5 mL) of the concentrated acid for experiments, and only after careful explanation of safety requirements. The use of dropper bottles is highly recommended. Students in years 7-10 can only use solutions <4 M.
Disposal: Waste solutions of this chemical may be disposed of down the sink (to sewer), after making the solution pH: 8-10.
