Hazards of hexavalent chromium in aluminum conversion coating
I use Alodine 1132 regularly to conversion coat aluminum plate. I understand that Type 1 conversion coatings utilize hexavalent chromium which is a constituent of Alodine 1132. What are the associated health risks and what precautions can be taken to avoid exposure to this hexavalent chromium.
Thank

The MSDS on the product you mentioned should contain all of the appropriate safety precautions to use when using that product.

Hi Peter,
There are a lot of concerns when working with Hexavalent. If you go to the Osha site you can find out a lot of information.
The usual PPE and perhaps a respirator should be used. If you have tanks they should be properly ventilated.
If this is a production line you may need to test your employee's or yourself for exposure.
The Osha site can really help you out - Small Entity Guide for the Hexavalent Chromium Standards.
Hope this helps,
