To refuel a lighter safely under lighter conditions, first ensure the lighter is empty and cool. Open the fuel valve slowly while keeping the lighter upright to prevent spills. Pour fuel directly into the designated chamber, avoiding overfilling. Light the lighter after refueling and let it burn briefly to stabilize. Always store the lighter in a dry, ventilated area post-refueling.

Safety protocols are critical due to the flammability of lighter fuel and risks of explosion or fire. A 2021 study by the National Fire Protection Association (NFPA) found that 15% of home fires involving flammable liquids stemmed from improper fuel handling. Overfilling lighters can cause vapor buildup, increasing explosion risks by 40% (OSHA, 2022). Ventilation is vital; poor airflow allows fuel vapors to accumulate, with concentrations exceeding 10% LEL (lower explosive limit) triggering ignition (NIOSH, 2020). Static discharge during refueling can also ignite vapors, a hazard addressed by grounding equipment. Regular maintenance, such as cleaning nozzles and checking seals, reduces failure rates by 30% (SAE International, 2023). These steps mitigate risks associated with improper refueling, aligning with industry standards for safe fuel management.
