Tankerman · Static — Settling Time
After loading a static-accumulator oil, gauging/sampling with metal equipment through an ullage port should wait approximately:
- AAbout 30 minutes for the charge to relax/settle✓ Correct
- BNo wait is needed
- CSeveral days
- DUntil the next port
Explanation
Static-accumulator (low-conductivity) products retain an electrostatic charge after flow stops. A settling (relaxation) time of about 30 minutes lets the charge dissipate before introducing conductive equipment, reducing the risk of an incendive spark.
