• Locate grounding points on the tankers and transfer pump.
• Make connections to damaged tanker first to avoid a potential spark.
• When possible, grounding systems should be established up hill and outside of the
Hot Zone.
• Resistance measurement should be compliant with your local jurisdiction which
usually follows NFPA 472 @1000or lessor NEC @ 25or less, lower is always
better. Higher resistance means longer static discharge time.
STEP 1:
Hazmat Grounding & Bonding
Site Considerations
Installing the Grounding System
NOTE: One or more rods may be needed for each grounding system to obtain an
acceptable grounding resistance. Multiple rods should be 3to 6feet apart and
connected to each other via jumper cable.
• Install/establish three separate static grounding systems, one for the distressed
tanker (X1), one for the recovery tanker (X2) and one for the pump (X3). When the
pump is not mounted to the fire truck, they should be at least 10 feet apart.
• The grounding sites should be up hill and up wind as well as outside of the
distressed tanker’s hot zone.
WARNING: Make sure the ground rod is fully screwed tight into the Driver /
Extractor tool before driving it into the ground to avoid thread damage.

STEP 2:
Conduct independent Fall-of-Potential tests on each of the
grounding systems.
1. Insert the auxiliary test electrode Za few inches into the ground and 50
to 80 feet away at a location that is central to the three grounding system
Xrods.
2. Insert the auxiliary test electrode Ya few inches into the ground at a
distance approximately 30 to 45 ft from the first ground system X1 and in
a straight line with the Zelectrode.
3. Connect the Red, Blue and Green test wires to the grounding rod(s),
electrodes and instrument as shown.
4. Press and hold the Test button until reading stabilizes to measure the
resistance.
5. Repeat steps 2, 3 and 4 for grounding systems X2 and X3.
After achieving the acceptable resistance, disconnect the meter and auxiliary rods Y
and Zbefore Step 3, connecting the tankers and pump to their grounding systems.

STEP 3:
Following the diagram, perform the below steps in the following order:
Connect a grounding cable to the distressed tanker first and then to
its grounding system X1.
Connect a grounding cable to the recovery tanker first and then to its
ground system X2.
Connect a grounding cable to the transfer pump first and then to its
grounding system X3.
Connect a bonding cable to the distressed tanker first and then to
the recovery tanker.
Connect the hoses to the pump and tankers.
Begin the transfer process.
NOTE: X3 is not needed if the pump is mounted to a fire truck.
