Xylene is a flammable liquid, so it is important to store it in a safe and secure container. The best type of tank for xylene is a metal or plastic tank that is specifically designed for storing flammable liquids. The tank should be equipped with a lid that can be securely closed, and it should be located in a well-ventilated area away from sources of heat and ignition.

Here are some additional tips for safely storing xylene:

* Keep xylene away from open flames and other sources of heat.

* Do not smoke or eat in areas where xylene is stored.

* Wear gloves and eye protection when handling xylene.

* If xylene spills, clean it up immediately with a cloth or paper towels.

* Dispose of xylene properly by contacting a hazardous waste disposal company.
