Chemical storage help

Can powder chlorine (in bags) and PH up (in a container with a lid) be stored together? I have a plastic garden type box with hinged lid I have outside. It’s not air tight. Can those two chemicals safely be together in that small box? I googled it and get conflicting results. Any guidance for this new pool owner is appreciated. Trying to be careful. Thanks

Good morning. We would not recommend storing these two chemicals together rather, have them in their own sealed containers with a buffer in between them.
