Which of the following is the correct control measure for fire/ignition risk during fuel handling?

Static electricity buildup during fuel handling can create a spark strong enough to ignite flammable vapors. Grounding and bonding are the direct controls that prevent that spark by giving charges somewhere to go and by making all conductive parts share the same electrical potential. Grounding ties the equipment, like the truck and fueling hardware, to earth so any charge dissipates safely. Bonding connects all conductive pieces together, so the truck, hose, nozzle, and receiving tank aren’t at different potentials when fuel is moving. Together, they prevent a discharge at the moment of transfer, which is where ignition risk is highest. Other measures have important safety roles but don’t address ignition from static discharges as effectively. PPE and ventilation protect workers and reduce vapor concentrations but don’t stop a spark from forming. Water detection paste is used to spot leaks, not to control ignition risk. Inspecting for leaks is crucial for leak prevention, but it doesn’t directly prevent static discharge ignition during handling.
