Proper ventilation and disposal for Type II Anodizing...

[quizzical1]

Hi All,

We are considering anodizing our own aluminum parts in-house and questions have been raised as to what the proper ventilation and disposal of spent materials should be.

Some here say no extra ventilation is needed and neutralizing old sulphuric acid with baking soda and pouring down the drain is fine while others (like me) feel a ventilation hood to the outside and additional containment measures are needed prior to disposing the acid. Anyone familiar with the Standards for this?

I cant help with any standards you may need to comply with,

But i do know anodizing releases hydrogen gas, so i would pay close attention to venting unless u want to spread your baths and building over a large area... explosively!
