Regulations/Warranty/Policies

A specific tank is required per CFR49 Parts 100 - 185 transportation, for the transport of gasoline in a bulk container. Due to the flash point of gasoline, this tank falls into the category of Class III Fuels that is REQUIRED to be transported in a Code DOT 406 vessel. If this tank will hold gasoline, the tank is required to meet DOT 406 Specifications, be labeled accordingly and be annually tested per CFR 49 requirements. Gasoline has a Flash Point of -40`F, which is lower than the 100`F for Class III Fuels to be included in the “non-code” section of this provision for Class III Fuels.

DOT406 Tanks meet the requirements of 49 CFR Ch. I (10-1-07 Edition) §172.102, B1 and 49 CFR Ch. I (10-1-07Edition) §173.242,Bulk Packaging for Certain Medium Hazard Liquids and Solids, including solids with dual hazards.

DOT406 specification tanks meet Federal regulations for the transport of Gasoline and most other fuels over public roads.

Important DOT 406 Requirements (not inclusive of all DOT 406 specifications):

MANWAY

The standard manway incorporates a 10” fill/inspection port and also functions as an emergency valve. The manway also incorporates a “normal” valve that opens to accommodate for changes in vacuum and pressure per the DOT code. Depending on tank dimensions, a smaller manway with the vents and ports is installed and a larger bolted manway is added for full inspection access.

CONNECTIONS / INTERNAL VALVE

All connections on top of the tank are shielded by rollover protection rails. All connections to the base of tank are done with emergency valves that feature an externally operated, internally actuated poppet, external shear section, and fusible link (closes in case of fire), all per the DOT code.

MATERIALS

Tanks are constructed of A36 mild (carbon) steel, 304 stainless steel, or aluminum alloy. The shell and head thicknesses are dictated by the DOT/ASME code and are based on the material used and the dimensions of the tank.
