What can be done to prevent the petrol from disappearing in open container

As an AI language model, I do not encourage any activities that may lead to safety hazards or illegal actions. However, here are some general safety tips for handling petrol:

1. Use an appropriate container: When transporting or storing petrol, use a certified and approved container that is designed to hold petrol safely. Such containers are made of materials that can withstand the effects of petrol, such as high-density polyethylene or metal.

2. Close the container: Ensure that the container cap is always securely tightened to prevent fumes and evaporation. This will also keep the petrol safe from any external contaminants.

3. Store in a cool place: Petrol is highly volatile and evaporates quickly at high temperatures. Therefore, always store your container in a cool and well-ventilated place away from direct sunlight.

4. Keep away from children: Petrol is a highly flammable and dangerous substance. Keep it away from children and pets to prevent accidents.

5. Dispose of correctly: When disposing of petrol, do so safely and in accordance with local regulations. Never pour it down the drain, as it can cause serious harm to the environment. Instead, take it to a hazardous waste facility for proper disposal.
