Tankerman · Bonding & Static
During tank cleaning or gauging, a recommended precaution against static ignition is to:
- AInsert equipment immediately after stopping loading
- BDisconnect the ship-shore bonding cable
- CUse only nylon ropes for sampling cans
- DWait a relaxation period after loading before introducing metallic equipment into the tank✓ Correct
Explanation
After loading, a relaxation/settling period (commonly about 30 minutes) allows accumulated static charge to dissipate before metallic gauging or sampling equipment is introduced, reducing spark risk.
