Just came to think of it, there is no such thing such as a difference
between the dusts and the fumes in Quebec's exposure limits for
1-Chromate (processing of chromite),
2-Butyl chromate, tertiary,
3-Chrome metal,
4-Chrome II compounds,
5-Chrome III compounds,
6-Chrome VI hydro-soluble,
7-Chrome VI hydro-insoluble, certain compounds.
Only 2 of these carry a C designation, item 1 and 7
But, there is such a difference between the fumes and dusts for =
manganese
as I told the list recently.
