I store liquid chlorine (the picture of the gallon jug of blue whale shock) in a cool dry place like my garage or in a plastic storage shed. It is similar to household bleach so you can store in your cabinet in laundry room if needed. LC tends to degrade more over time so keep out of the heat. I have found that the tablets give off more odor because the top is not very well sealed. I would keep that outside in a plastic storage container. You can store those 2 items together if needed outside if no other option. It is best to store MA separately from the chlorine. It is also best to store MA in a plastic shed outside due to fumes. It will attack anything iron so do not put in your garage.
