What precaution should be taken when using lighter fluid?

When using lighter fluid, the most critical safety precaution is to never add it to an already lit fire. This is because adding lighter fluid to a flame can cause a sudden flare-up or explosion. The volatile substances in lighter fluid can ignite rapidly and unpredictably, leading to dangerous situations that can cause severe burns or uncontrollable fires.

It's essential to understand that lighter fluid is meant to be used as a starter for starting fires safely and effectively, but it should only be applied to unlit materials, minimizing the risk of excess heat causing a rapid ignition. Ensuring that lighter fluid is used only before lighting the fire is a vital part of fire safety and risk management practices.
