Jeremy Saint-Peyre Posted January 5, 2022 Share Posted January 5, 2022 Hello everyone, I am home processing 16mm, mostly Fomapan R100, and i am also home brewing my chemistery (hardening bath, bleach, clearing, developper is a photo paper one) : Sulfuric Acid, Potassium Permanganate, Potassium Alun, Sodium hexametaphosphate, Sodium Bisulphate and Sodium Metabisulphite. I use caoutchouc gloves (the pink kind you use for house cleaning) and safety goggle. My question is more about the mask and filter, i use this mask : https://www.cazabox.com/47353-demi-masque-a-filtre-nu-avec-soupape-d-expiration-sup-air.html and those filters : https://www.cazabox.com/7160-galette-filtrante-ammoniac-en14387-vendu-par-2-sup-air.html. What are your opinions/gear ? Thanks, Jeremy Quote Link to comment Share on other sites More sharing options...
Site Sponsor Robert Houllahan Posted January 5, 2022 Site Sponsor Share Posted January 5, 2022 If you are mixing powdered then that mask is fine as you just want to ensure that you do not inhale any dust. We mix liquid chemistry at Cinelab under a vent hood so no masks are really needed for that with proper ventilation. Quote Link to comment Share on other sites More sharing options...
