Grounding Road Tankers (Tank Trucks)
Resistance Vs Impedance Vs Capacitance,
Ground Resistance & Continuous Ground Loop Monitoring

Grounding road tankers during hazardous gas, liquid & powder transfers can be a difficult business due to lack of training of the driver (e.g. lowering the trailer legs and connecting hoses before the grounding system has a GREEN LED flashing), lack of routine maintenance of the system, weather and ground conditions (snow, ice, rain and salt).

An Ideal Road Tanker Grounding installation:

• Must have a verified ground connection that is checked by a responsible electrical engineer on a routine basis.
• Must have a designated ground point on the truck with a metal to metal connection to the chassis and tank of less than 10 Ohms. Designated grounding points are usually brass pins or stainless-steel tabs and must be clearly identified.
• Must have a grounding system that complies with Industry Standards, Guidance and Recommended Practices (IEC TS 60079-32-1, NFPA77 and API RP 2003).
• Must have a grounding system installed to Ex/manufacturers specifications and has routine maintenance carried out by a responsible electrical engineer.
