Calcium can burn and become something else because it is a metal on the periodic table. Like many metals, calcium is highly reactive. It is reactive to both water and air. This is because the air has oxygen in it. Therefore, the calcium should be stored in containers where air can’t seep in and all of the air should be withdrawn from this container.
Also, water should not be able to get into this container as well. Even if there is a flood, the container should not be able to have the water seep in. The container itself is important too because the container should not corrode or being able to corrode later. The container should be kept out of extreme temperatures as well.
I cannot find information specific to calcium. The general principles of storage of chemicals in a lab is to keep like with like. You must avoid contaminating one substance with another.
That is, always segregate antagonistic substances to prevent dangerous interactions. My guess is that you keep calcium away from air and moisture, so in a dry cabinet. It may be that it is normally stored in a mixed form.
In it pure state, calcium is highly reactive. It can react with air or water. If it is kept freely, it will react with air or water.
To prevent calcium from reacting with air or water, it is stored in the laboratory in a dark glass that has a tightly closed lid under a layer of paraffin, kerosene or any other similar mineral oil substance.
Paraffin and kerosene are commonly used to store calcium because it does not contain water which protects calcium from being exposed to any moisture in the air that may cause it to react.
