2. Placarding 49 CFR Part 172 Subpart F

3. Placarding Objectives
Upon completion of this presentation, you will be able to:
Recognize the conditions that do not require placarding
Define the difference between the two placarding tables
Select the appropriate placards for a given hazmat shipment or vehicle load
Identify the requirements for placarding for subsidiary hazard classes or divisions
Identify placard specifications, visibility, and display

4. Placarding Overview
When certain hazardous materials are transported or handled or certain quantities of hazardous materials are shipped, it is imperative that the materials can be quickly identified by the handlers, transporters, and emergency response personnel. Consequently, we use placards to help communicate the hazards of the material that we are shipping.

5. Placarding Overview
Placards are similar in shape, color, and design to a hazardous material hazard class label but are larger than labels.
Placards help communicate the material’s hazards that are being transported.
Placards also help guide emergency responders during a hazardous materials incident.

6. DOT Placards –

7. Applicability
Depending on the hazard class and quantity of hazardous material being shipped, placarding may apply to each person who offers (shipper) for transportation or transports any hazardous material under the DOT regulations.
Placarding does not apply to:
Limited Quantities (Ltd. Qty.);
Other Regulated Materials (ORM-D);
Infectious substances (6.2);
Class 9 materials, domestic shipments by highway;
Combustible liquids (non-bulk);
Small Quantities (173.4);
Materials of Trade (173.6 MOTs); &
Hazardous materials prepared in accordance with
NOTE: Also see (f) for additional placarding exceptions.
UN1263

8. Providing and Affixing Placards: Highway
The shipper must offer/supply placards, unless that placard is already displayed on the motor vehicle and the carrier must affix placards to the motor vehicle.
Shippers are not responsible for materials already on the transport vehicle.
NOTE: For special placarding provisions for highway & rail, see , , &
Joe Carrier
Jane Shipper

9. Prohibited and Permissive Placarding
Placards may not be displayed or affixed for materials that are: not hazmat; do not represent the hazard(s) of the hazmat; and do not conform to placarding requirements.
Any sign, advertisement, slogan (such as “Drive Safely”), or device that, by its color, design, shape or content, could be confused with any placard prescribed in this subpart may not be displayed.
Placards may be displayed for a hazardous material, even when not required, if the placarding otherwise conforms to all applicable requirements.

10. Selecting Placards – Table 1 or Table 2
Placarding applies to each bulk packaging, freight container, unit load device, transport vehicle, or rail car containing any quantity of a hazardous material.
To determine the placard type, find the proper shipping name in the Hazardous Materials Table (HMT) and refer to Column 6, Label Codes. Generally speaking, the primary hazard class or division defines the placard which should be used.
In order to determine placarding applicability, you need to look at Placarding Tables 1 & 2 ( (e)).
Table 1
Table 2

11. Selecting Placards – Table 1
Always placard for Table 1 hazardous materials.
NOTE: Think of Table 1 as the really “nasty” stuff, such as Poison Gases (2.3), Poison Inhalation Hazard (PIH) Liquids or Solids (6.1 with a PIH), and Dangerous When Wet Materials (4.3).
(a)

12. Selecting Placards – Table 2
Placarding for materials in Table 2 is based on aggregate (combined) gross weight (total hazmat weight + packagings):
Unless excepted, bulk packaging placarding is required for any amount.
If the aggregate gross weight is 454 kg (1,001 lbs) or more, placarding is required for non-bulk packaging.
In other words, placards are not needed for less than 1,001 lbs.
“Gross weight” is the weight of the packaging plus the weight of its contents.
“Aggregate gross weight” is the accumulated (combined) totals of all Table 2 hazardous materials.
This exception does not apply to bulk packagings (IBC/totes) or hazmat subject to subsidiary placarding under
(c)

13. Selecting Placards – Table 2
(c) (continued)

14. Table 2 Exceptions
When non-bulk Table 2 hazardous materials are transported by highway or rail, placards are not required on:
A transport vehicle or freight container which contains less than 454 kg (1,001 lbs) aggregate gross weight of hazmat covered by Table 2; or
A rail car loaded with transport vehicles or freight containers, none of which is required to be placarded.
NOTE: This exception does not apply to bulk packagings or hazardous materials subject to subsidiary placarding under
< 1,001 Pounds
Toluene UN1294
(c) (continued)

15. Placarding for Subsidiary Hazards
Subsidiary placards are only required for:
Poison Inhalation Hazards (PIH),
Certain types of Radioactive (7), &
Dangerous When Wet (4.3).
The class or division number is required for subsidiary hazards; it became mandatory on 10/1/05.
NOTE: You may placard for other subsidiary hazards (such as 2.1, 2.2, 3, 5.1, or 8) even though subsidiary placarding is not required for those materials.
EXAMPLE:
Corrosive liquids, water-reactive, n.o.s.
Primary Placard
Subsidiary Placard
Kob’s Transportation Services

16. Placarding Example 1
From the given information, does a shipment containing a 250 lb cylinder of Boron Trifluoride require placarding?
From the HMT, you can see that Boron Trifluoride is a Division Division 2.3 materials are listed on (e) Table 1. All materials on Table 1 require placarding for any amount, thus placards must be used for this 250 lb shipment.

17. Placarding Example 2
From the given information, does a shipment containing 300 lbs of Arsine require placarding?
From the HMT, you can see that Arsine is a division 2.3 & 2.1 material. Division 2.3 materials are listed on (e) Table 1 & 2.1 materials on Table 2. If a material is both on Table 1 and Table 2, then you always placard. All materials on Table 1 require placarding for any amount, thus placards must be used for this 300 lb shipment.

18. Placarding Example 3
Which of the following placards are required for a shipment containing 800 lbs of Paint (Class 3); 900 lbs of Paint Related Material (Class 3); & 700 lbs of Phosphoric Acid Solution (Class 8)?
Flammable placard
Corrosive placard
Both Flammable & Corrosive placards
No placards are required
First you should look up the materials in the placarding tables, as shown on the next slide:

19. Placarding Example 3 Continued

20. Placarding Example 3 Continued
As you can see, none of the materials are listed on Table 1.
Each of the materials is listed on Table 2, although if they were shipped by themselves, none of them meets the weight requirement for placarding 454 kg (1,001 lbs).
However, the aggregate gross (combined) weight of the three materials is 2,400 pounds, which exceeds the weight requirement for Table 2 placarding. As a result,
Both Paint and Paint Related Material are Class 3 hazards (Flammable Liquids) and require the Flammable placard.
Phosphoric Acid Solution is a Class 8 hazard (Corrosive) and requires the Corrosive placard.
This means that both the Flammable placard and the Corrosive placard are required for this shipment.

21. Dangerous Placard Exception
If a freight container, unit load device, transport vehicle, or rail car which is carrying two or more different hazard classes from Table 2 in non-bulk packaging, and the aggregate weight of the shipment is 454 kg (1,001 lbs) or more, then a Dangerous placard may be used instead of the separate hazard class placards.
However, if 1,000 kg (2,205 lbs) aggregate gross weight or more of one hazard class (category) of hazardous materials is loaded on the freight container, unit load device, transport vehicle, or rail car at one facility, then the placard specified in Table 2 must be applied for that material.
(b)

22. Placarding Example 4
You saw earlier that for a shipment containing 800 lbs of Paint; 900 lbs of Paint Related Material; & 700 lbs of Phosphoric Acid Solution, both the Flammable & Corrosive placards were required because they were both Table 2 materials & the aggregate gross weight (2,400 lbs) was greater than or equal to 454 kg (1,001 lbs).
However, instead of using both the Flammable & Corrosive placards, you may replace both placards with one Dangerous placard. By using one placard instead of both placards, placarding costs may be reduced. + =

23. Placarding Example 5
Suppose you wanted to ship 1,600 lbs of a Class 3, 700 lbs of a Class 8, & 220 lbs of a Division 2.3 material all on the same truck. What would be the required placards?

24. Placarding Example 5 Continued
A Poison Gas placard MUST be displayed because Division 2.3 materials are listed on Table 1. +
Since there is greater than 1,001 lbs of Table 2 materials (2,300 lbs), placards are required for them as well. In this example, you can use both Flammable & Corrosive placards. +
Or, the Dangerous placard could be used instead of the Flammable & Corrosive placards, thus eliminating one placard!

25. Placarding Example 6
A shipper wants to ship 1,600 lbs of a Class 3 (Flammable Liquid) material and 1,500 lbs of a Class 8 (Corrosive) material in non-bulk packages. The shipment does not involve limited quantity containers. Are placards required? If so, which ones and where?

26. Placarding Example 6 Continued
Option 1:
Yes, the Flammable and Corrosive placards are required because the aggregate gross weight exceeds 1,001 lbs (3,100 lbs). Placards go on each side and each end (all four sides) of the motor vehicle.
Option 2:
Or the Dangerous placard may be used instead of each individual placard. Placards still go on each side and each end (all four sides) of the motor vehicle. OR OR

27. Exception for Empty Non-bulk Packages
A Table 2 non-bulk packaging that contains only hazmat residue need not be included in determining placarding requirements.
This exception does not apply to bulk packages (IBC/totes) or hazmat subject to subsidiary placarding under
Additional placarding exceptions are found in 49 CFR (f).
(d)

28. Placard Specifications – Durability
Placards must be durable and weather resistant.
Placards should not show any deterioration or substantial reduction in effectiveness after 30 days of exposure to conditions normally encountered during transportation.
(a)

29. Placard Specifications – Design
Except for size and color, the printing, inner border, and symbol on each placard must conform to the specimen designs found in 49 CFR through , as appropriate.
The dotted line border shown on each placard is not part of the placard specification, except when used as an alternative for the solid line outer border to meet the requirements for contrast with background ( (d)).
Except as indicated, no modification in the placard specification is allowed.
Text indicating the hazard is not required, except for the Class 7 (Radioactive) or Dangerous placard.
Text can be omitted from the oxygen placard only if the specific ID Number is on the placard.
Primary placards and subsidiary placards must have the hazard class or division number on the bottom of the placard.

44. Segregation & Separation (S&S) By Highway 49 CFR 177.848

45. Segregation & Separation (S&S) By Highway Objectives
Upon completion of this presentation, you will be able to:
Identify what segregation and separation is based on
Know how to use the Segregation & Separation (S&S) Table
Determine if subsidiary hazards affect segregation & separation
Know whether or not acids and cyanides, cyanide mixtures, or cyanide solutions may be transported together
Identify the requirements concerning load securement

46. Segregation & Separation Overview
When transporting hazardous materials, sometimes the packages in the vehicle must be properly segregated and separated.
Separation means that the materials will not co-mingle.
Otherwise, an extremely dangerous situation could be created.

47. Hazard Class/Division
Segregation and separation is based on the material’s hazard class or division as displayed on the labels or placards applied to the package.
Subsidiary hazards may also affect segregation and separation requirements.
NOTE: Limited Quantities and ORM-D materials do not require segregation and separation since hazard class labels are not required.

48. Loading & Unloading of Transport Vehicles
Anyone who loads or unloads the hazardous material is subject to the carrier regulations applicable to that mode of transport.
49 CFR – addresses loading, unloading, and transport requirements applicable to hazard classes/divisions and specifically listed materials.
173.30

49. Segregation Table for Hazardous Materials (S&S Table)
The segregation and separation requirements are determined by using the Segregation Table for Hazardous Materials (S&S Table) that is found in section of the regulations.
The S&S Table identifies the hazardous materials which must be loaded, transported, or stored separately for highway transportation.
(d)

50. Segregation Table for Hazardous Materials (S&S Table)

51. S&S Table Overview
Hazard class/divisions are listed along the top and left side of the S&S Table. The list on the left shows names and hazard class/division numbers. The top row shows only the hazard class/division numbers.

52. S&S Table Overview
NOTE: The S&S Table does not list every hazard class & division.
For example, there is no listing for Division 6.1 Poisonous Solids, Poisonous Liquids in PG II or III, Division 6.2 (Infectious Substances), Class 8 Corrosive Solids, Class 9 (Miscellaneous materials), or ORM-D.
A material that is not listed has no segregation or separation requirements.

53. How To Use The S&S Table How to use the S&S Table:
To use the S&S Table, go down the column on the left until you find the hazard class/division of one of the hazardous materials.
Next go across the top row until you find the hazard class/division of the other hazardous material.
Then find the spot where the two hazardous materials intersect. Where they intersect, you’ll find the segregation and separation symbol that applies.

54. S&S Table Symbols The following symbols are used on the S&S Table:
Blank space (or absence of any hazard class/division): usually no segregation restrictions apply.
X: materials cannot be loaded, transported, or stored together.
O: materials must be separated when being loaded, transported, or stored together.
*: These materials are referred to in a separate segregation table ( (f)) for Class 1 explosives.
A: applies only to ammonium nitrate or ammonium nitrate fertilizer.
(e)

55. S&S Table Example 1
Suppose you wanted to transport a Class 3 Flammable Liquid with a Class 8 Corrosive Liquid. What does the S&S Table say about this?
There are no segregation or separation restrictions because there is a “blank space” where the two hazard classes intersect.

56. S&S Table Example 2
Suppose you wanted to transport Methyl Ethyl Ketone (Class 3) with Phosphoric Acid Solution (Class 8 Corrosive Liquid). What does the S&S Table say about this?
There are no segregation or separation restrictions because there is a “blank space” where the two hazard classes intersect.

57. S&S Table Example 3
Suppose you wanted to transport a Class 2.1 Flammable Gas with a Class 8 Corrosive Solid. What does the S&S Table say about this?
As you can see, no Class 8 Corrosive Solids Columns are listed in the S&S Table, thus no segregation and separation restrictions apply for the materials.

58. S&S Table Example 4
Suppose you wanted to transport a Class 3 Flammable Liquid with a Division 5.1 Oxidizer. What does the S&S Table say about this?
Since the symbol “O” is listed where the two hazard classes intersect, the materials must be separated if they are going to be transported together.

59. Subsidiary Hazard Classes/Divisions
Subsidiary hazard classes/divisions must also be considered when determining segregation and separation requirements.

(e)(6)

60. Subsidiary Hazard Classes/Divisions
There may be some times when the subsidiary hazard represented by a material will impact the segregation and separation even though the primary hazard doesn’t.
The S&S requirements for subsidiary hazard classes/divisions are also determined by using the S&S Table.
You look up the subsidiary hazard in the S&S Table and compare it with the primary hazard or subsidiary hazards of the other material.
Let’s look at an example:
(e)(6) (continued)

61. Subsidiary Hazard Example
Suppose you wanted to transport a Class 3 Flammable Liquid with a Class 8 Corrosive Liquid that also has a subsidiary hazard of Division 5.1 Oxidizer. What does the S&S Table say about this?

Isopropanol UN1219
From: Infotrac Inc. 200 N. Palmetto St. Leesburg, FL 34748

62. Subsidiary Hazard Example Cont.
First compare the primary hazards: the Class 3 Flammable Liquid with the Class 8 Corrosive Liquid.
So far, there are no segregation or separation restrictions because there is a “blank space” where the two primary hazard classes intersect.

63. Subsidiary Hazard Example Cont.
Now compare the Class 3 Flammable Liquid with the subsidiary Division 5.1 Oxidizer. What does the S&S Table say about this?
Since the symbol “O” appears where the two hazard classes intersect, the materials must be separated if they are going to be transported together.

64. Subsidiary Hazard Example Cont.
As you just saw, there were no separation & segregation (S&S) requirements for the Class 3 & Class 8 Liquid. However, there were S&S requirements for the Class 3 & Division 5.1, in this case, an “O”. Consequently, the most restrictive segregation & separation requirements must be followed.

65. Cyanides And Acids
It’s extremely important NOT to transport or store cyanides, cyanide mixtures, or cyanide solutions with acids because when they are mixed, they produce hydrogen cyanide gas, which is deadly to humans.
Always check for the name “cyanide” and “acid” in chemical names.
NOTE: Cyanides and acids may be transported together if they are shipped under (e).

66. Loading/Unloading Requirements
Anyone who loads the transport vehicle is responsible for assuring load securement.
All loads must be secured to the transport vehicle so that moving, shifting, tipping, & falling cannot occur.
Some common load securement methods are to physically tie, block, and brace the load. Tarps, coverings, enclosed vehicles, side rails, gravity, and pallet configurations should not be assumed sufficient securement.
See 49 CFR for additional info.
Packages with orientation arrows must remain “up” in the transport vehicle.
