Attachment 1, passage 2Ullore niti torere moluptassum quiae © ARE YOU TRANSPORTING HAZARDOUS MATERIALS? Do you carry hazmat as part of your job? Liquid fuels, paint thinners, pesticides, and even lithium cells and batteries are all classified as hazardous materials (hazmat), because they can pose an unreasonable risk to health, safety, and property when transported in commerce (§ 171.8) Department of Transportation hazmat regulations only apply to the transportation of hazardous materials IN COMMERCE. Whether you are self-employed or work for a large company, it is your responsibility to know if you are dealing with hazmat. One possible starting point for determining whether a product you transport is hazmat is to consult the product’s Safety Data Sheet (SDS), provided by the manufacturer. This should include a transportation hazard classification for the product, with a four-digit ID number, a proper shipping name, the hazard class, and the packing group for the product (in Section 14: Transportation Information, per the example on page 5). In other words, they do not apply if you are transporting hazmat for non-commercial purposes in a private motor vehicle. You are responsible for transporting hazmat in accordance with the Hazardous Materials Regulations (HMR; 49 CFR Parts 171 – 180), including properly classifying and packaging the materials with all required hazard communication. These requirements may be dependent upon the quantity and hazard of the specific material (see the Hazardous Materials Table (HMT) § 172.101). 4#

Attachment 1, passage 46 6 MATERIALS OF TRADE or MOTs, are a certain category of hazmat which, when transported in small quantities as part of a business, are subject to fewer HMR requirements due to the limited hazard they pose. WHY DO MOTs MATTER TO YOU? MOTs are hazmat, other than a hazardous waste, that are carried on a MOTOR VEHICLE in certain quantities 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 (including its auxiliary equipment), such as a spare battery or gasoline; or directly support a principal business of a private motor carrier (including vehicles operated by a rail carrier) that is other than transportation by motor vehicle – for example, chemicals for landscaping, pest control, painting, or plumbing services, or gases for welding. There is an exception for MOTs that provides less stringent regulatory requirements. When transported in accordance with § 173.6 of the HMR, the following requirements are NOT applicable to MOTs: • Shipping papers • Emergency response information • Placarding • Formal training or retention of training records. The MOTs exception does not apply to transport of these hazardous materials by other modes of transport, including by aircraft or vessel. The following HMR limitations and requirements DO apply to MOTs*: • • • • Material limitations; Quantity limitations; Packaging, marking, and labeling requirements; and General knowledge of MOTs (found in § 171.8). *See § 173.6 “Materials of trade exceptions.” In addition, the exception does not apply to these materials when in motor vehicles transported by ferry.

Attachment 1, passage 6QUANTITY LIMITS Use the flow chart below to determine the quantity limitations per package of a given MOT, based on Packing Group (PG) and hazard class/division. You can find the PG and hazard class/division listed in Section 14 of the SDS, columns 5 and 3 (respectively) of the Hazardous Materials Table, or as part of the Basic Description on previous shipping paper(s). Note that the aggregate gross weight of all MOTs—that is, the total weight of all hazardous materials and its packaging loaded on a single vehicle— may not exceed 200 kg (440 lbs.). *** BE CAREFUL! MOTs have strict quantity limitations. If you exceed these limits, the material will be fully regulated under the HMR. Start with the Packing Group (PG): PG I PG II, PG III or no PG Maximum amount of material in one package is 0.5 kg (1 lb.) for solids, or 0.5 L (1 pint) for liquids What is the hazard class or division? Class 3, 8 Div 4.1, 5.1, 5.2, 6.1 Class 9 Is it a liquid in a diluted mixture not exceeding 2% concentration? Div. 4.3 Div. 2.1, 2.2 Div. 6.2 Maximum gross capacity of each package is 30 mL (1 oz.) Each cylinder may not weigh more than 100 kg (220 lbs.) gross See specific packaging and quantity limits listed in § 173.6(a)(4) NO YES Maximum gross mass of each package is 30 kg (66 lbs.) for solids, including lithium batteries contained in equipment, or 30 L (8 gal) capacity for liquids May be transported in a tank having a capacity of up to 1500 L (400 gal) ***Not including diluted mixtures (not exceeding 2 percent concentration) of Class 9 materials PHMSA | PIPELINE AND HAZARDOUS MATERIALS SAFETY ADMINISTRATION 9#

Attachment 1, passage 7PACKAGING AND MARKING REQUIREMENTS MOTs MUST BE PACKAGED AND MARKED AS FOLLOWS: Packaging Marking • • • • • • The packaging must be the manufacturer’s original packaging or of equal or greater strength and integrity. Packagings must be leak tight for liquids and gases and sift proof for solids. Packages must be properly closed, secured against movement, and protected against damage. Outer packagings are not required for receptacles (such as cans or bottles) that are secured against movement in cages, bins, boxes, or compartments. Gasoline must be transported in a metal or plastic container meeting HMR or OSHA requirements (see §§ 173.6(b)(4) and 173.202 in the HMR). Cylinders and pressure vessels must conform to HMR requirements, except that outer packagings are not required. • • • • The packaging must be marked with either a common name (such as “gas” or “spray paint”) or a proper shipping name from the HMR (such as “isopropyl alcohol”). A tank containing a diluted mixture (not more than 2% concentration) of a Class 9 material must be marked with the identification number on two opposing sides. Cylinders and pressure vessels must be marked with the proper shipping name and identification number and have a hazard class warning label. If the package contains a reportable quantity of a hazardous substance, it must be marked “RQ” (reportable quantities are found in Appendix A of Section 172.101 in the HMR). Division 6.2 infectious substances must be contained in a combination packaging which meets the following requirements: MATERIAL REQUIREMENT Liquids • • Inner packaging must be leakproof Outer packaging must contain sufficient absorbent material to absorb the entire contents of the inner packaging. Sharps • • Inner packaging (sharps container) must be constructed of a rigid material resistant to punctures and securely closed to prevent leaks or punctures. Outer packaging must be securely closed to prevent leaks or punctures. • Solids, Liquids, Sharps Outer packaging must be a strong, tight packaging securely closed and secured against shifting, including relative motion between packages, within the vehicle on which it is being transported. 10#
