Ammonia fumes are irritating to the respiratory system and eyes. Some people are more sensitive than others. Keep all solutions of ammonia covered or in the fume hood. Clean up spills immediately.
Nitric acid used in the synthesis will burn skin. Gloves provide only a temporary layer of protection. If you spill HNO3 on your glove, remove it immediately, wash your hands, and get a new pair. Follow this procedure if your gloves develop holes or become discolored. Clean up any bench top spills immediately, to avoid accidental burns. Use caution when dispensing from repipets, to avoid splatter of reagents.
Aluminum tops of the hot water baths are hot enough to cause burns. Use caution when using the water bath to heat reaction mixtures.
Goggles must be worn at all times in the laboratory. Do not remove them from their proper position, in front of your eyes, until you leave your room. Goggles worn on the forehead do not provide eye protection!
All reaction mixtures and cobalt-containing solutions should be placed in the labelled waste drums. Unused acid and base solutions can be rinsed down the drain with lots of water.
