That is the basic principle that I'm trying to establish from the debate. Then the rest of the "stuff" can be brought into it.
I'm doing this for my education as well as others that I know can learn and possibly be safer because of this discussion.
The last time I got into a HAZMAT discussion with Turtle, all kinds of stuff got brought into it and the thread went on and on. Determined to avoid that this time, I made sure we were trying to answer the same question before I offered my answer. To that question (defined above) I have nothing more to say.
Regarding your education, Rocketman, there are no shortcuts when it comes to HAZMAT. Drivers hauling the stuff are expected to know and follow the applicable regs, and exactly what is applicable varies depending on the circumstances. I do not hold myself out as someone who is educated in HAZMAT, and I would never advise anyone to rely on what is written in an online open forum for HAZMAT information. HAZMAT is a complicated topic. It is important to master it at the driver's level if you are going to haul the stuff.
I like to keep things as simple as I can when dealing with HAZMAT questions, and the very first step in that is to be crystal clear about what question you are trying to answer. That will likely lead you to another question, and another. The trick is to be clear on each question and take them one at a time.
So, having said all that, let me demonstrate with the questions Rocketman asked above. He said, "It is illegal to placard a vehicle that is carrying non-hazmat materials, correct? So, if it is, would using placards on a hazmat load that does not require placards (table 2, less than 1,001lbs) not be a violation also?"
Let's take the questions one at a time:
Question 1. It is illegal to placard a vehicle that is carrying non-hazmat materials, correct?
Answer: Yes, Rocketman, that is correct. It is illegal to placard a vehicle that is carrying non-HAZMAT materials (assuming you are talking about standard HAZMAT placards used in the transportation industry).
How do I know? Well, I just do. It's something I learned when studying for my HAZMAT CDL-endorsement, and taking various HAZMAT training classes offered by my carriers over the years.
Is that an answer you wish to rely on? Not if you want to be confident in the answer. You and I will both want to know that the answer is right and based on an authoritative source.
So I go to Google and ask your question there. After clicking a few links I figure out that you are asking about "placarding." I then go to the online regs and use the search engine there to find:
49 CFR 172.502 (a) Prohibited placarding. That is the reg that says placards are prohibited on vehicles that are not carrying HAZMAT. See the reg itself for the exact language.
Thus, Rocketman's question 1 is asked and answered. It did not need clarification because the question was clear enough.
Question 2: "So, if it is (illegal to placard a vehicle carrying non-HAZMAT materials), would using placards on a hazmat load that does not require placards (table 2, less than 1,001lbs) not be a violation also?"
Answer: No. It is not a violation to use placards on a vehicle that is carrying a HAZMAT load when placards are not required. You may use placards on that vehicle if you wish. (Diane and I would never have such a wish for a number of reasons.)
How do I know? Well, I just do. It's something I learned when studying for my HAZMAT CDL-endorsement, and taking various HAZMAT training classes offered by my carriers over the years.
Is that an answer you wish to rely on? Not if you want to be confident in the answer. You will want to know that the answer is right and based on an authoritative source.
So, once again, I go to Google and ask your question there. Links there take me back to the regs and I find the answer to the specific question you are asking. It turns out the be the same reg that answers question number 2:
49 CFR 172.502 (c) Permissive placarding.
Now notice this, and this is very important for anyone wishing to get into a HAZMAT discussion (debate). In asking question number 2, Rocketman built in an assumption. Referring to answer number one, he said, "So if it is (illegal) ...."
In saying "So if it is ...." he is assuming that the answer to question 1 has some bearing on question two. Well, it might or it might not. In this case, it did not.
Question 1 is about placarding a vehicle that is not carrying HAZMAT.
Question 2 is about placarding a vehicle that is carrying HAZMAT but circumstances are such that placards are not required.
These are two different questions and the answer to one has nothing to do with the answer to another.
The secret to HAZMAT understanding lies not in finding clear answers (though that is the ultimate goal), the secret to HAZMAT understanding lies in dropping all assumptions and then asking clear questions.
The better you get at that, the quicker you will get to the clear answers you seek. HAZMAT is complicated because the answers vary so much from item to item and circumstance to circumstance. But for a particular item in a particular circumstnace, clear answers can be found.
As a driver who transport different kinds of HAZMAT in different circumstances, I don't think about the big picture or what so-and-so said about a load he once did or a customer he once served. I think only about the particular item and the particular circumstances.
