# DuBois Chemical, Inc. — Hazardous Materials Safety Interpretation **Citation:** 16-0146 **Type / status:** guidance / guidance **Agency:** Pipeline and Hazardous Materials Safety Administration **Effective:** Not stated **Published:** 2016-12-09 16-0146 response to DuBois Chemical, Inc. concerning 172.506. ## Document text <<>> Regulatory Specialist DuBois Chemicals, Inc. 3630 East Kemper Road Sharonville, OH 45241 Reference No. 16-0146 Dear Mr. Polk: This letter is in response to your September 6, 2016, email requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to providing hazardous materials placards to motor carriers under § 172.506(a). We have paraphrased your questions and answered them in the order you provided: Q1. You ask the meaning of "provide" as it is enforced in § 172.506(a) of the HMR. A1. The HMR do not define the word "provide." However, according to conventional resources, such as the Merriam-Webster Dictionary, it means "to make something available" and "to give something wanted or needed to someone or something." Q2. You ask if § 172.506(a) requires those who offer hazardous materials to: (1) physically hand placards to motor carrier drivers or present them along with shipping papers before or at the time the hazardous material is offered for transportation; or (2) have placards readily available and accessible in organized files for carriers to pick up as needed. You further ask which manner meets "provide" as enforced. A2. Section 172.506(a) specifies that the placards are to be offered to a motor carrier prior to or at the same time a hazardous material is offered for transportation, but it does not specify how they are to be made available. Therefore, the offeror may use any method that meets the requirements in § 172.506(a). It is the opinion of this Office that the following examples comply with this requirement: the offeror (1) physically hands applicable placards to the motor carrier; (2) physically applies applicable placards to the container/vehicle; or (3) makes applicable placards available to the motor carrier in <<>> T. Glenn Foster Chief, Regulatory Review and Reinvention Branch Standards and Rulemaking Division <<>> Please submit this as a letter of interpretation. Mr. Polk spoke with Shelby. Please let me know if you have any questions. Thanks, Jordan From: jay.polk [mailto:jay.polk@duboischemicals.com] Sent: Tuesday, September 06, 2016 2:06 PM To: INFOCNTR (PHMSA) Subject: Interpretation for §172.506(a): Providing and affixing placards: Highway §172.506(a) simply states that the shipper "shall 'provide' the motor carrier with the required placards for the materials being offered... unless the carrier's motor vehicle is already placarded for the material." What is the enforceable definition / interpretation of the term "provide"? I have been unable to find a definition or an official interpretation for what is meant or intended by the term "provide". Do the required placards have to be physically handed to the driver or presented with the shipping papers, either prior to or at the time the material is offered? Or by having the required placards for all materials being offered made readily available in organized, readily accessible files for the carriers to pick-up as needed, is this meeting the intent for the term "provide"?
