Sandhya:
My experience with NO2 has all been in the environmental health arena. NO2 is nasty. The NAAQS for a 1 hour averaging time is 100ppb. The EPA documentation supporting the NAAQS is substantial and would be worth reviewing. Proceed with appropriate caution in reviewing the entire experimental set up. I would be curious as to the objectives of the experiments and the experience of the investigators and their technical staff.

Dear
All,Â
We have a laboratory planning to run experiments
with high concentrations of NO2 gas[2500-5000 ppm]. Please
advise on any specific specific safety precautions.

Thanks,Â
