Advice
Unseen fuel system risks can become business-critical failures
Many commercial sites operate diesel storage that:
- Has not been formally inspected in years
- Has undetected corrosion, leaks, or containment failures
- Presents a hidden pollution or fire risk
- Could fail when generators are needed most
A single issue can lead to:
- Environmental enforcement action
- Insurance claim disputes
- Generator failure during outages
- Costly remediation and downtime
How often should you inspect?
Annual inspection is the widely adopted best practice.
Higher-risk systems may need more frequent checks:
- Has not been formally inspected in years
- Has undetected corrosion, leaks, or containment failures
- Presents a hidden pollution or fire risk
- Could fail when generators are needed most
We can help you define the right risk-based inspection schedule.
