In the event of a fuel leak, what material should be used to soak up the spill?

In the event of a fuel leak, sand or absorbing material is the appropriate choice because these substances are effective at soaking up the fuel, preventing it from spreading further and reducing the risk of fire or environmental contamination. Sand is often readily available and acts quickly to contain the liquid, allowing for easier clean-up and minimizing potential hazards.

Using water is not advised, as it can spread the fuel further and create a more significant hazard, especially in terms of fire risk. Soap does not have the necessary absorbent properties to manage fuel spills effectively and would not aid in containing the leak. Using leaves or plant material is similarly ineffective, as these materials do not properly absorb fuel and could also contribute to environmental damage. Therefore, sand or an appropriate absorbing material is the safest and most effective response in a spill situation.
