What 178.345-5 means in plain language
FMCSR 178.345-5 governs specific requirements for the handling and transport of hazardous materials in bulk containers or tanks. The regulation establishes standards for how these containers must be prepared, marked, and managed during transport to prevent spillage, contamination, or exposure.
In practical terms, if you're hauling hazmat in bulk—whether that's chemicals, fuel, or other regulated substances—this code requires that your equipment and procedures meet precise federal standards. Violations typically involve improper container preparation, inadequate sealing, or failure to follow required procedures before the load begins moving.
What our enforcement data actually shows
Across our 13 million+ inspection records, 178.345-5 has been cited only once in our all-time database. In the last 12 months, there have been zero citations nationwide. In the last 90 days, zero citations.
The one citation on record did not result in an out-of-service order. The OOS rate for this code is 0.0%—substantially lower than the all-FMCSR average OOS rate of 31.4%. This code ranks #2796 of 3,036 FMCSR codes by citation volume, making it one of the least-frequently enforced hazmat-related violations in roadside inspections.
The rarity of citations suggests either strong compliance across the industry or that inspectors encounter this violation infrequently relative to other hazmat infractions.
Who gets cited most
Our inspection records show that enforcement for this code is extremely limited. The only citation in our database was issued to a carrier operating a bulk equipment vehicle. Because there is only one citation on record, there is no meaningful geographic or carrier distribution to report. This singular enforcement event provides little basis for predicting which states or fleet types face higher risk.
How severe is this compared to similar codes
Other hazmat regulations in the same category show dramatically higher enforcement volume and severity. For example:
- 177.834A-HMC (General loading/unloading hazmat) has 3,954 citations with a 99.2% out-of-service rate, indicating that nearly every inspection finding results in immediate vehicle removal from service.
- 177.817(a) (Placarding violation) has 2,274 citations with a 75.1% out-of-service rate, reflecting the critical importance of proper hazmat identification.
- 172.602(c)(1) (Maintenance/accessibility of Emergency Response information) has 1,464 citations with a 0.0% out-of-service rate, showing that some hazmat documentation issues are treated as correctable defects.
By comparison, 178.345-5's single citation and 0.0% OOS rate place it at the bottom tier of hazmat enforcement severity. This suggests the violation, when detected, is typically not considered an immediate safety threat warranting vehicle removal.
How to avoid it
Because this violation is rarely cited, specific co-occurring patterns in our database are minimal. However, hazmat bulk transport requires rigorous pre-trip discipline:
- Inspect container integrity before loading. Check for cracks, leaks, dents, or corrosion on the tank or bulk container. Any damage must be repaired or the container replaced before transport begins.
- Verify proper sealing and closure systems. Confirm that all access plates, valves, and hatches are securely closed and that gaskets are in place and intact.
- Confirm proper placarding and labeling. Ensure placards are legible, properly positioned, and match the material being transported.
- Review your shipper's paperwork. Cross-check the manifest, bill of lading, and safety data sheets against your load before departure. Discrepancies signal that preparation may be incomplete.
- Document pre-trip findings. Write down what you inspected, any defects noted, and corrective actions taken. This creates a clear record if an inspector questions your compliance later.
- Know your vehicle's specifications. Understand the maximum load capacity, weight distribution limits, and any equipment-specific requirements for your particular bulk tank or container.
Hazmat transport demands precision. The low citation rate for 178.345-5 does not mean the rule is unimportant—it may instead reflect the fact that carriers hauling bulk hazmat operate under intense regulatory scrutiny and tend to comply closely with all preparation requirements.
