What are the safety precautionary measures in using fuels or fire?

When using fuels or fire, it's essential to maintain proper ventilation to prevent the buildup of harmful gases. Always store fuels in designated, approved containers away from heat sources and open flames. Keep a fire extinguisher nearby and know how to use it, and never leave a fire unattended. Additionally, wear appropriate protective gear and follow safety guidelines specific to the type of fuel or fire being used.
