Safety gear for black and white reversal processing

[Jeremy Saint-Peyre]

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

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.
