Hi Kelly, you should not get any smell from your monomer, if in it's original container sealed and put away. I store both my gallon bottle and my smaller one i use for mobile in my garage which i can acces from inside house. I decant into smaller bottle from large,, and can never ever smell a thing in my garage.
Only time there is a smell is when I am working from home and have not use correct extraction, or opened a window lol,,, or emptied my bin,, always always will be from soaked up monomer the smell or from my hands down wipes etc (on a wipe) etc, and not from the actual container.
HTH xxx
