As an expert in the field of petroleum products, I can provide you with a comprehensive answer regarding the shelf life of kerosene.

Kerosene, also known as paraffin oil, is a petroleum product that is widely used for heating, lighting, and as a fuel for certain types of engines. The shelf life of kerosene is influenced by several factors, including storage conditions, exposure to air, and the presence of impurities. Proper storage and handling can significantly extend the shelf life of kerosene.

Storage Conditions:
The ideal storage conditions for kerosene are crucial to maintaining its quality and extending its shelf life. Kerosene should be stored in a cool, dry, and well-ventilated area. Exposure to heat can cause the kerosene to evaporate or degrade, while exposure to cold can cause it to become more viscous.

Exposure to Air:
Kerosene can react with oxygen in the air, which can lead to the formation of gum and other impurities. To minimize this, kerosene should be stored in airtight containers that are designed to prevent the ingress of air.

Presence of Impurities:
Impurities such as water, rust, and other contaminants can significantly reduce the shelf life of kerosene. It is essential to check storage containers frequently for rust and ensure that they are clean and dry before filling them with kerosene.

Metal Storage Containers:
Using metal storage containers for kerosene is recommended, as they are less likely to harbor bacteria and other microorganisms that can contaminate the fuel. It is important to inspect these containers regularly for signs of rust and to keep them in good repair.

Concrete Surfaces:
Storing kerosene on a concrete surface is not recommended, as the moisture from the concrete can seep into the storage container and contaminate the kerosene. Instead, kerosene should be stored on a pallet or a metal oil drip pan to prevent contact with moisture.

Shelf Life:
The shelf life of stored kerosene can vary, but under optimal conditions, it can last for approximately 12 months. However, this can be shorter if the kerosene is exposed to poor storage conditions or impurities.

In conclusion, the shelf life of kerosene is dependent on proper storage and handling practices. By following the guidelines mentioned above, you can ensure that your kerosene remains in good condition for an extended period.
