A chemical tank is a big container that can hold different kinds of liquids and chemicals. Just like how you have different containers for your toys or snacks, companies and factories also need to store liquids safely.
The chemical tank is very strong, made of a special material that won't break easily. It has a big cap that can be opened and closed to add or take out liquids. Think of it like a big water bottle, but for chemicals.
The chemical tank also has pipes connected to it which allow liquids to be pumped in or out. These pipes work like straws, moving the liquids in and out of the tank.
Chemical tanks are important because they help keep the liquids safe by preventing them from accidentally spilling or mixing together. This is especially important for dangerous chemicals that need special care and protection to avoid harm to the environment and people.
