Module 9 Materials of Trade Introduction

• DOT has established Materials of Trade (MOT)
  exceptions that allow companies to transport
  small quantities of certain hazardous materials
  used in support of their primary business. These
  materials must meet specific guidelines to be
  classified as MOT.
• Materials classified as MOT are exempted from
  many regulations of the Hazardous Materials
  Regulations (HMR), such as shipping papers,
  emergency response information, or placarding,
  and do not require drivers to have any formal
  training in handling them.
• After completing this module, you will be able to
  explain
• What qualifies as MOT.
• What hazard classifications can qualify for the
  MOT exception.
• MOT quantity limitations and packaging
  requirements.
• MOT marking and labeling requirements.

LESSON 1

• What is a Material of Trade (MOT)?

4
Material of Trade Introduction

• DOT defines MOT as limited quantities of a
  hazardous material, other than a hazardous waste,
  that may be carried on a motor vehicle to
• Protect the health and safety of the motor
  vehicle operator or passengers, such as insect
  repellant or a fire extinguisher.
• Support the operation or maintenance of a motor
  vehicle, such as a spare battery or gasoline.
• Directly support the operations of the principal
  business, such as landscaping, pest control,
  painting, plumbing, or welding services.
• In the propane industry, a common example of MOT
  is a bobtail driver transporting a small
  container of methanol to assist in removing water
  from within a propane tank.
• Not all hazardous materials qualify for the MOT
  exception. Lets review the requirements for both
  hazard classification and quantities permitted.

5
Classification Requirements

• To be transported as MOT, the hazardous material
  must belong to one of these specific classes or
  divisions
• Flammable Gases such as acetylene and propane.
• Non-flammable Gases such as oxygen, nitrogen.
• Flammable and Combustible Liquids such as
  gasoline, paint, paint thinner.
• Flammable Solids such as charcoal.
• Dangerous When Wet Materials such as some
  fumigants.
• Oxidizers such as hydrogen peroxide.
• Organic Peroxides such as benzoyl peroxide.

6
Classification Requirements, cont.

• Poisons such as pesticides.
• Some Infectious Substances such as diagnostic
  specimens.
• Corrosive Materials such as muriatic acid, drain
  cleaners, and battery acid.
• Miscellaneous Hazardous Materials such as
  asbestos and self-inflating lifeboats.
• Consumer Commodities such as hair spray and spray
  paints.
• You may not deal with all of these hazard classes
  as part of your day-to-day job, but you should
  know what they are in case you are asked to
  transport these MOT.

7
Quantity Limits

• The amount of hazardous mterial that can be
  transported under the MOT exception is limited.
  Drivers must know the capacity and weight of
  containers they are transporting to ensure they
  are in compliance with the quantity limits. This
  is especially important if more than one MOT is
  being transported. The total gross weight of all
  MOT carried on one motor vehicle cannot exceed
  440 lb.
• The following limits are based typically on
  hazard class divisions and packing groups
• If a material is a high-hazard material
  (PackingGroup I), the maximum amount in one
  package is one pound for solids, or one pint for
  liquids.
• If the material is a medium- or lower-hazard
  material (Packing Group II or III) with the
  exception of Division 4.3 and Consumer
  Commodities (ORM-D), the maximum amount in each
  package is 66 lb for solids, or 8 gallons for
  liquids.

8
Quantity Limits, cont.

• For Division 4.3 materials (Packing Group II and
  III), the maximum amount in each package is one
  ounce.
• Each cylinder containing a gas (Division 2.1 or
  2.2) may not weigh more than 220 lb.
• A diluted mixture of a Class 9 material may be
  transported in a tank having a capacity of up to
  400 gallons.

9
Packaging Requirements

• According to DOT regulations, MOT must be
  packaged in the following ways
• Liquids and gases must be packaged in enclosed,
  leak-proof containers and secured to prevent
  movement or damage during transport.
• Cylinders used to transport Division 2.1
  (Flammable Gas) or 2.2 (Non-flammable Gas) MOT
  must conform to the packaging, qualification,
  maintenance, and use requirements of the HMR,
  except that outer packaging is not required.
• Manifolding cylinders are authorized if valves
  are closed tightly.
• Gasoline must be in metal or plastic packaging
  and conform to HMR and OSHA requirements.

10
Packaging Requirements, cont.

• Materials must be packaged in their original
  packaging, or in a package of equal strength and
  quality.
• Nonbulk packaging, other than cylinders, must be
  marked with the name of the material being
  carried. DOT-specification cylinders must be
  marked and labeled as required by the HMR.
• NOTE Outer packaging is not required for cans
  and bottles secured in cages, carts, bins, boxes,
  or compartments to prevent movement. However,
  they cannot simply be placed in a can inside a
  bin. They must be secured to prevent movement.

11
Safely Transporting MOT

• As with all hazardous materials, MOT must be
  handled properly to minimize risk to yourself and
  others. Treat all of these materials with the
  same care and precaution you would if they were a
  placarded load. A driver who does not comply with
  these guidelines for transporting MOT may sustain
  fines ranging from 275 to as much as 100,000
  per day as well as possibly face criminal
  penalties.
• In addition to HMR requirements, you should also
  follow any safety precautions present on the
  materials commercial packaging.
• If you have any questions about how a particular
  hazardous material should be handled or
  transported, refer to its Material Safety Data
  Sheet (MSDS).
