To light a kerosene lighter safely, first ensure the lighter is empty of residual fuel and properly vented. Open the fuel valve completely using the flip-top or lever mechanism. Light the wick with a match or lighter, then adjust the flame to a stable size by turning the control nut. Keep the flame away from flammable materials and avoid overfilling the fuel chamber.

The process prioritizes safety and functionality. Kerosene lighters require precise fuel management to prevent leaks or explosions. According to the Consumer Product Safety Commission (CPSC), 15% of home fires involving lighters in 2022 were linked to improper fuel handling, including overfilling or faulty valves. A study by the National Fire Protection Association (NFPA) found that 70% of kerosene lighter malfunctions occur when the wick is damp or the fuel valve is partially closed, leading to unstable flames. Proper pre-use checks reduce risks: opening the valve fully ensures even fuel distribution, while avoiding overfilling prevents vapor buildup. The CPSC recommends allowing the lighter to dry completely after extinguishing the flame to prevent water damage to the wick. Adhering to these steps aligns with industry standards and significantly lowers accident rates.
