Where you store your chemicals is very important because if not stored in the proper place, they can become less effective, and also dangerous. You want to store your chemicals away from any sunlight. Ideally, you want them stored in a place that is dry and cool. You should also be aware of what chemicals you store together. You don't want any two chemicals that do NOT mix stored next to each other on the same shelf. If the chemicals fell, they could mix together, and you would have a very dangerous situation.
Also remember to keep chemicals out of reach of children and pets. These chemicals are very harmful if swallowed. In case of being swallowed, contact a physician or poison control immediately to seek medical attention.
