Nitric acid and bromine combination is generally used for aromatic bromination. It can be safely manipulated inside a chemical fume hood using proper PPE and by using proper reaction set-ups.

Good luck.

I‰??m posting the question on behalf of a Canadian colleague. His direct e-mail is andrewcutz**At_Symbol_Here**hotmail.com

This is Andrew Cutz, CIH in Toronto, Canada. Would you be aware of any specific chemical laboratory guidelines when working with Bromine in combination with Aqua Regia? A client would like to inspect the chemical laboratory fume hood and associated mechanical exhaust system - addressing on-going occupant "bromine odour" complaints and concerns. Looks like that this is a pretty nasty (hazardous) stuff... not to be used by novices!

Any guidance and potential leads would be much appreciated at this stage.

Thank you in advance,

Andrew Cutz
