Hazmat Grounding & Bonding
Site Considerations
•
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 uphill and outside of the
H
ot Zone.
•
Resistance measurement should be compliant with your local jurisdiction which
usually follows NFPA 472 @ 1000Ω or less, or NEC @ 25Ω or less; lower is
always better. Higher resistance means longer static discharge time.
Installing the Grounding System
STEP 1:
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.
•
Install/establish three separate static grounding systems, one for the distressed
tanker
pum
•
The grounding sites should be uphill and upwind, as well as outside of the
distressed tanker's Hot Zone.
NOTE:
