Improper disposal of old petrol is not only harmful to the environment, but also illegal. Pouring petrol onto the ground or into storm drains poses a significant risk to humans, animals, and the environment due to its toxic nature. It’s crucial to follow proper guidelines and regulations when disposing of old petrol to avoid fines and potential legal consequences.

By disposing of old petrol properly, you protect the environment and adhere to legal regulations. In the next section, we’ll discuss how to safely store and transport old petrol before disposing of it.
