How can the build up of static electricity be prevented so that a static spark does not ignite flammable vapors?

🔍 Key Concepts

• Static electricity and how it is created during fuel transfer or cargo operations • The role of bonding and grounding on vessels handling flammable liquids • How flammable vapors can be ignited by even a small static discharge

💭 Think About

• Which option talks about directly connecting equipment to safely discharge any static build-up? • Do any of the choices sound like they address a different hazard (like humidity control or shutting down power) rather than static itself? • Think about standard procedures during bunkering or tank-cleaning: what is ALWAYS done with hoses and metal parts before starting transfer?

✅ Before You Answer

• Verify which choice refers to bonding/grounding of all conductive parts used in the transfer operation. • Check whether dehumidifying air is a standard maritime safety practice for static control around flammable liquids (look at what your textbook emphasizes). • Confirm that the correct practice deals with controlling the charge on the equipment and hoses themselves, not just the surrounding environment.

How can the build up of static electricity be prevented so that a static spark does not ignite flammable vapors?

Each machine and hose involved in the operation should be grounded.

All electrical circuits near and around the fueling operations should be opened.

A dehumidifier used in spaces containing flammable liquids will significantly reduce the possibility of static charges being generated.

Static neutralizers can be used to reduce ionization in the air.
