spraying, paint suppliers generally recommend a NIOSH Type C air
line respirator with a full-face piece or hood operated in a positive
mode. Whatever respirator you choose, ensure that it complies with
all applicable codes or regulations in your jurisdiction. In Canada,
3M recommends that you follow the CSA Standard Z94.4 or the requirements
of the authority having jurisdiction in your region.

to read and follow these instructions very carefully and to conduct
a fit check or user seal check every time the respirator is put
on. The user instructions are usually provided with the original
packaging of the respirator.
