In general, the hazmat shipping containers are manufactured with fiberboard as well as with stainless steel. In addition to that, I will like to mention that the conventionally used hazmat shipping container holds 55 gallons and weight around 400 to 1.000 pounds.
Yet, we can notice that more and more trucking companies nowadays are performing the hazmat transportation with totes and bulk tanks. These trucks are very functional for the liquid hazardous materials. Also, bulk tanks these days are manufactured in a size that varies between the size of the drums and one of the totes.
The trucking companies that are performing the hazmat transportation process with bulk tanks shall be very careful not to perform transportation of for example food or industrial items with the same trucks.
That is prohibited because the bulk tanks are holding combustible, toxic, as well as corrosive materials. It is a rule no.1 among transportation companies, which they must follow.
Identification Number
All trucks that are performing hazmat transportation shall follow the rules and regulations that do apply for this type of transportation, and that includes an identification number. This identification number shall be placed on a hazard warning placard.
