So I am going to start a set of experiments involving the following metal nitrates:
- Cobalt nitrate hexahydrate
- Barium nitrate
- Cerium nitrate hexahydrate
- Ammonium nitrate nonahydrate
- Iron(II) nitrate nonahydrate
All the products are from Sigma-Aldrich. As I was going through the SDS data sheets, my gloves and googles matched the safety standard on all these products, except my gas mask.
I have a P2 level gas mask, but the recommended is a P3 level mask. I will be performing all my experiments in a standard fume hood and it has all the required ventilation.
Do I still need the P3 level mask or the fume hood is enough? Asking this because I am kinda scared doing these experiments as I will be working with heavy metals for the first time.
