The shipping papers do not determine whether or not something is HAZMAT. Shipping papers have their own set of rules are are filled out based on what the shipment is. First thing you have to know is the definition of HAZMAT. The DOT defines it as:
Hazardous materials [HAZMAT] means any material that has been designated as hazardous under 49 U.S.C. 5103 and is required to be placarded under subpart F of 49 CFR part 172 or any quantity of a material listed as a select agent or toxin in 42 CFR part 73.
The way that materials are designated as hazardous is the Secretary of the Department of Transportation determines that a material poses an unreasonable risk to the population or the environment. Many materials pose such a risk in any and all quantities, while other materials pose such risks only in certain quantities.
The key part of the definition is
the material must be designated as hazardous, and it
must be required to be placarded. If the material doesn't meet both of these two requirements, it is not hazardous material (HAZMAT). The language is very precise. Everything in the regulations concerning hazardous material hinges on knowing the correct definition of HAZMAT. Assumptions should not be made.
There are certain materials, most notably those found on Table 2, which are HAZMAT, but only in certain quantities, and in lesser quantities are not considered HAZMAT by the Department of Transportation (for the purposes of transportation). Table 2 materials which are not in quantity to require placarding may be hauled by anyone without having to have a CDL with a HAZMAT endorsement. To refer to such material as HAZMAT (or even non-placardable HAZMAT, of which I am often guilty) is incorrect, since you must have a CDL and a HAZMAT endorsement to haul HAZMAT. I use the term "non-placardable HAZMAT" to indicate Table 2 materials which would be placardable in quantities of more than 1000 pounds, but are not otherwise required to be placarded or require an endorsement. I'm trying to get away from that.
Page 25 of the Hazardous Materials Compliance Pocketbook does, indeed indicate the three ways in which HAZMAT is to be indicared on the shipping papers (except mine is page 23, not 25). Pages 22-26 of the Hazardous Materials Compliance Pocketbook describe the requirements for shipping papers, and in all instances those requirements are for hazardous materials, including those on page 25 (my page 23). In fact, the sentence preceding the the three ways states:
"Hazardous materials are required to be identified on shipping papers in one of three ways."
One of the most important parts of that sentence is the first two words, "hazardous materials".
Since we know the definition of hazardous materials, there should be little confusion on how shipping papers are to be filled out. The "X" in the "HM" column is to denote Hazardous Materials, as defined above, not non-hazardous materials.
In fact, in the
Electronic Code of Federal Regulations:172.201 it states...
(4) A shipping paper may contain additional information concerning the material provided the information is not inconsistent with the required description. Unless otherwise permitted or required by this subpart, additional information must be placed after the basic description required by §172.202(a).
A HM column marked with an X for a non-hazardous material is not consistent with the required description and applicability of the paperwork requirements. Applicability can be found in
172.200:
§ 172.200 Applicability.
(a) Description of hazardous materials required. Except as otherwise provided in this subpart, each person who offers a hazardous material for transportation shall describe the hazardous material on the shipping paper in the manner required by this subpart.
Again, note the use of the term "hazardous material". It's very specific.
The confusion, I think, most often comes from the Table 2 stuff. If it's on that table and is 1001 pounds or more, it's HAZMAT and must be placarded. If it's on that table and is 1000 pounds or less, it's really and truly not hazardous material according to the Secretary of Transportation and thus requires no placarding or endorsement, and no indication in the HM column on shipping papers. Don't assume the shipper always prepares the paperwork correctly. If the freight is a 50 pound bag of copper sulfate and the shipping papers are marked with an "X" in the HM column, then the shipping papers are, absolutely, incorrectly prepared. The reverse is also true, where I have seen HAZMAT freight not properly marked in the HM column. That kind of stuff, either way, gets corrected by the shipper before I take the freight.
Oftentimes, and it's easy and natural to do, people read the HAZMAT regulations and will apply them outside the scope of the regulations themselves. They make assumptions and leaps based on common sense, rather than on the details of the regulations. It's not unlike the other topic in this thread, where people read the hours-of-service regulations, which apply to commercial motor vehicles, and start applying them outside the scope of commercial motor vehicles. Like the example used where someone works on the weekend at Ace Hardware, while driving a CMV during the week, and having to log their work time at Ace Hardware. The same rules apply to a cargo van driver, but only if the cargo van driver was operating a CMV during the previous 7 days. If not, then the regulations cannot be applied outside the scope of what they cover. Once those 7 days are over, your logging days are over, you are no longer required to log at all, ever, unless you operate a CMV. It's very much like your very first week in a big truck. How in the world did you log those previous 7 days? You didn't, of course, because you weren't required to. It's the same when you drive a cargo van. If you haul a HAZMAT load once in a while, you have to continue to log for 7 days after hauling the load, but once those 7 days are up, you no longer have to log, since you aren't driving a CMV anymore. If you haul one HAZMAT load per week, then you have to log essentially all the time. But if it's once a month or once a quarter, you only have to log for 7 days.
Hauling HAZMAT in a cargo van requires special diligence beyond that of most who haul it in a big truck, as you have to be more intimate with certain regulations that big truck drivers rarely need to concern themselves with. The biggest one is knowing which types of HAZMAT cannot be hauled in the cab of a truck. It's something most big truck drivers never even think about, because they don't haul freight in their cab, much less HAZMAT freight in the cab. But cargo vans do. Every load on a cargo van is considered to be in the cab of a truck, regardless of whether the van has a bulkhead.
Because of the importance of knowing the regulations of what can and cannot be hauled in a cargo van, and what is and is not considered HAZMAT, I made a concerted effort to educate myself on the matter. That included reading the rules and regulations, of course, but also included in-depth conversations with a very good friend of mine who is the DOT complainace officer in charge of highway, rail, air and marine transportation at Vanderbilt Chemical (subsidiary of
R.T. Vanderbilt) in my home town. His job is to know these rules forwards and backwards. I have benefited greatly from his knowledge.
Copper Sulfate is classified as UN 3077, with the Proper Shipping Name of:
ENVIRONMENTALLY HAZARDOUS SUBSTANCES, SOLID, N.O.S.
Other Names: Blue copper, Blue stone, Blue vitriol, Copper (II) sulfate, Copper sulfate, Cupric sulfate, Cupric sulphate, Sulfate de Cuivre
DG/ADR Class: 9
Packing Group: III
Hazchem Code: 2X
Poisons Schedule: S6
N.O.S. is used when the a chemical's name does not specifically appear in the HMT. There are lots of substances like that. Alcohol is one. While ethanol appears in the table and has a proper shipping name of Ethyl Alcohol or Ethanol, an alcohol that is not listed specifically in the table will be described as "Alcohol, n.o.s" or "Flammable liquid, n.o.s".
I used copper sulfate because it is an often expedited material used in agriculture as a soil additive, pesticide, feed additive, a germicide, a leather and textile mordant, a pigment in the printing industry, in the manufacture of batteries, in electroplating and electro refining of copper, in the production of certain medicines, as a wood and pulp preservative, in engraving and lithography, in ore, steel and rubber processing, as an asphalt treatment, and in chicken processing plants. It's a chemical that I'm very familiar with. Also because it's a Class 9, which is kind of a catch-all Class that can confuse people.
