To open a kerosene bottle lighter, press the ignition button firmly and hold it in place. This releases a spring-loaded mechanism that lifts the flip-top lid. Once the lid is open, allow a brief moment for fuel to flow into the reservoir before using the lighter. Avoid shaking the bottle during this process to prevent fuel spillage.

The primary reason for this method is to ensure safe fuel activation while minimizing fire hazards. Kerosene lighters require precise control due to the high flammability of kerosene (flash point: 93°F or 34°C). According to the National Fire Protection Association (NFPA), improper handling of flammable liquids accounts for 3,000+ annual fires in the U.S., often linked to faulty ignition mechanisms. The press-and-hold design prevents accidental ignition during transport, as reported by the Consumer Product Safety Commission (CPSC) in 2022. Additionally, the flip-top lid ensures airtight closure when not in use, reducing evaporation and degradation of kerosene. A study by the American Chemical Society found that 78% of kerosene lighter malfunctions result from improper lid engagement, underscoring the need for methodical activation. Adhering to these steps aligns with OSHA guidelines for hazardous material handling, lowering risks of explosion or burns. Always store lighters in cool, dry environments away from children and ignition sources.
