Which practice helps minimize static electricity when connecting hoses and fittings?

• A. Use non-conductive hoses only.
• B. Bond and ground the system, use conductive hoses, and minimize movement that generates static.
• C. Avoid grounding to prevent shocks.
• D. Keep hoses disconnected during operation.

Answer: (B)

Static electricity can build up when propane flows through hoses and fittings, creating a potential spark if charges aren’t safely managed. Bonding and grounding the system provides a path for any electrical charge to equalize with earth, so a spark is far less likely when connections are made. Using conductive hoses helps conduct those charges away from the connection points, rather than letting them accumulate on insulating surfaces. Minimizing movement that generates static through friction also reduces how much charge is produced during handling. In contrast, using non-conductive hoses traps charges, avoiding grounding increases the risk of a spark, and keeping hoses disconnected prevents safe operation.
