A frac tank is like a really big bathtub. But instead of holding water, it holds liquids and chemicals that are used in things like oil and gas drilling.
When workers need to transport or store these liquids, they use frac tanks. Think of it like moving water from one pool to another - you need a container to hold it while you move it.
Frac tanks are made of strong metal and have special features to help workers use them safely. For example, some have stairs and platforms so workers can get on and off the tank easily. Others have valves and pipes that let workers control how much liquid comes in and out of the tank.
Overall, frac tanks are an important tool that help people retrieve resources from the ground. But just like any tool, they need to be used carefully to make sure everyone stays safe.
