The Department of Transportation (DOT) mandates that Hazmat Placards be used when transporting hazardous materials and dangerous goods in the United States. Identify hazardous truck and container loads, such as chemical, flammable, explosive, and poisonous materials clearly with bright truck placards and DOT placards. This requirement may be met by the placards displayed on the freight containers or portable tanks loaded on a motor vehicle or rail car. (b) The required placarding of the front of a motor vehicle may be on the front of a truck-tractor instead of or in addition to the placarding on the front of the cargo body to which a truck-tractor is attached. (c) Each placard on a transport vehicle, bulk packaging, freight .

Applying the wrong placards to the load, not displaying enough of them or displaying them improperly, can potentially get you placed out of service under CVSA guidelines. Did I mention CSA points? In fact, add two rtucks points if your placed out of service. For basic placarding purposes, there are three key ae of information that you need to know right under your nose — in fact, right on the paperwork that was handed to you. Every shipment contains these key pieces of information.
Identifying this information and knowing how to use it will go a long way to determining placards and checking compliance. In the picture, we see a shipping paper with two how to check internet password materials that are highlighted. The shipping papers list the following:. The hazard class is required to be listed right after the proper shipping name.
In this case, the material is in hazard class is 8 which is a corrosive for each of the materials listed on the shipping paper. Knowing the hazard class will help find the right placard that will go with the hazardous material listed on the shipping paper.
Think of a hazard class or division as a category or bucket for hazardous material. Divisions are subcategories of a hazard class. This is because there is a varying degree of risk when dealing with explosives. TNT 1. Gases hazard class 2 are divided into 3 divisions: Flammable gas, non-flammable compressed gas and poison gas.
Also, get familiar with the names for each hazard class. We arr to figure out if the placarde are bulk or non bulk. For the previous example it appears that these are on skids and in cartons, which indicate individual non bulk packages. Knowing the difference is one of the most fundamental things in hazardous materials compliance that you must know. So how do you know if things are bulk or non bulk?
It depends on the capacity of the container or packaging the hazardous material is in. Non bulk hazmat is obviously going to be less than the figures I just gave you.
In my article hazmat bulk packaging I give you the figures right out of What animal eats the black footed ferret hazmat how to make a bubble bath without bubbles, check it out. No really, you need to read it, go there right palcards then come back. At its core, the dot hazmat placard regulations are pretty simple.
The hazmat regulations break placards into two distinct groups or tables each with their own requirements:. Poison gases, volatile explosives for example, need to be taken seriously. Column 1 of the table tells you the category hazard class or division if it applies and any other information. Column 2 tells you the name of the placard. Everyone has a name, and placards are no different! But according to the chart above, that would be incorrect. When we look in the Category column for hazard class 2 we see that it is listed as 2.
The placard name for the 6 or 6. Two different names, because the reality is, is that they are two different things — one is a gas, and the other is a liquid or solid that is giving off fumes. Also, the name aare the placard can occasionally determine what hazmat regulations apply to the load.
If you are transporting any amount of a Table 1 hazardous material, you MUST put placards on the transport vehicle. If you are transporting a table 1 hazardous material in commerce on a bicycle, you must have placards on that bike. Drivers, check with your company, companies check with the appropriate authorities in your state.
You have to placard for table 2 hazardous materials once you have 1, pounds of aggregate gross weight. What is aggregate gross weight?
It simply means that you add up the weight of all packages plus their contents and include that towards the 1, pounds. Suppose you have pounds of Corrosives class 8 and pounds of Flammable class 3. You add these materials together and you get 1, pounds of aggregate gross weight.
Your vehicle would then have to be placarded like this:. Each material is below the 1, pounds but together in aggregate they are over 1,lbs, which means the load would require placarding. One of what are placards on trucks biggest mistakes that companies and drivers make is thinking that you need 1, pounds of each class before you put placards on for a specific hazardous material.
This untrue as you saw above and you will receive a violation and maybe placed out of service. So a subsidiary hazard what is iso for psp a secondary hazard or hazard in addition to the primary hazard. Chlorine gas what is good for a migraine headache 3 hazards associated with it.
The primary hazard is 2. Not all hazardous materials that have a subsidiary hazard are required to be placarded wha their subsidiary whqt. The first are Hazardous materials that are poisonous by inhalation. That would be hazard classes 2. In other words, you have to be hauling placars very specific product, Uranium Hexafluoride. In addition to using a radioactive placard, Uranium hexafluoride requires a Corrosive placard. The corrosive placard is only required as a subsidiary hazard for Uranium What are placards on trucksspecifically.
Any other time a hazardous material with a corrosive subsidiary hazard is not required to be placarded for Corrosive. Did I beat that horse enough? Back to the Chlorine gas example; I mentioned earlier. Since none of the subsidiary hazards are any of the big 3, no subsidiary placard is required for Chlorine.
If you have any amount of a hazardous material that has a subsidiary hazard of the above three materials, you must use a subsidiary placard for it.
Once you have to use a subsidiary placard again, any of the above 3 you must placard the primary hazard also. You can permissibly placard for all other hazards if you want to. Just make sure that you display the placards as required. Keep in mind that you must always consider basic placarding first and then figure out whether or not you can use a Dangerous placard. What are placards on trucks put these on a tanker, an IBC tote or turcks tank for example.
You must have 2 or more categories hazard classes or Table 2 hazardous materials onboard that require different placards. Remember the definition I gave earlier on aggregate gross weight? It applies here to. You would no longer be able use a Dangerous placard to cover that Flammable material. To be in compliance with hazmat placard regulationsyou need three key pieces of information. This information can be found on your hazmat shipping papers that you were provided. Placarding violations tgucks remained one of the biggest reasons that drivers and companies both have racked up CSA points in the Safety Management System.
Getting placed out of service will get extra points added on. I am being told it is illegal to have placards in the cab with you.

These placards are labeled flammable solid and have a fire graphic. Red and yellow Red and yellow indicate organic peroxides which have the potential to ignite or explode these fall under the division 5.
Common examples are methyl ethyl ketone peroxide and benzoyl peroxide. Yellow and white Yellow and white represent radioactive substances that are often found in medical equipment. White and black Half white and half black signifies corrosive materials that can irritate and harm the skin.
Examples include batteries, hydrochloric acid, sulfuric acid and sodium hydroxide. These signs say corrosive, show substances spilling onto hands, and have the number 8. White with black stripes A white sign with black vertical stripes at the top and the number 9 at the bottom signals miscellaneous dangerous goods.
