What should you never do when refueling equipment?

Leaving equipment unattended while refueling poses significant safety risks. During the refueling process, the presence of flammable fuels and the potential for spills or leaks create hazardous conditions that require constant supervision. If the equipment is left unattended, there is a higher risk that dangerous situations can develop without immediate intervention, such as a fire starting from a spark or a spill leading to environmental contamination. Ensuring that someone is present during refueling can help in quickly addressing any issues that may arise and maintaining a safe environment. This practice is essential for maintaining workplace safety standards and preventing accidents related to fuel handling.

The other practices mentioned—checking for leaks, using approved nozzles, and refueling in well-ventilated areas—are important safety measures to mitigate risks associated with fuel handling.
