Federal Department of Transportation (DOT) Placarding of the Most Commonly Used Agricultural Chemicals in Ohio

AEX-595.3-92

Ohio farmers use a variety of chemicals to aid in the production of various commodities. When used correctly with adequate personal protection, these chemicals pose little if any threat to the farmer. Similarly, under normal circumstances, agricultural chemicals pose virtually no threat to the surrounding community or the consumers of treated farm products. One potential concern occurs when some of these chemicals are transported on public highways.

In the event of a traffic accident involving a vehicle carrying a hazardous material, there is a clear and imminent danger to the operator, emergency response teams and the surrounding community if these materials spill or catch fire. For this reason the Federal Department of Transportation (DOT) developed a system for rapid identification of these materials by emergency response teams. Certain specified hazardous materials require that placards, which readily identify the hazard, be placed on four sides of the vehicle transporting materials in quantities in excess of one thousand pounds (there are some exceptions that require placarding regardless of the amount). Furthermore, shipping papers (shipping orders, bills of lading, manifest or other shipping documents) must accompany the hazardous materials being transported.

Accessibility of shipping papers is important to emergency crews. By placing papers in areas prescribed by DOT, papers will be readily retrievable in case of an accident or emergency. Papers should be carried in a separate hazardous materials envelope, readily visible and within the drivers reach when restrained by a seat belt, or they should be in a pouch on the driver's door. When the driver is not in the vehicle, the papers should be placed in the door pouch or on the driver's seat.

In the state of Ohio, materials being transported to and from the farm are exempt from Ohio Public Utilities Commission jurisdiction. However, farmers may be covered under federal regulations. In the case of an accident, farmers may be held liable if they have not included shipping papers or properly placarded a load of hazardous material. Contact legal counsel for specifics of your potential liability.

Emergency responders in rural areas are often volunteer fire fighters, local sheriff deputies or the highway patrol. When responding to an accident or emergency, these individuals are trained to look for DOT placarding and hazardous material shipping papers. Loads of hazardous materials either not placarded or improperly placarded could put the lives of these individuals and the vehicle operator in jeopardy. This may result in rescue delay, loss of life and significant increase in costs.

The table on the back of this sheet contains important DOT identification information on 32 of the most commonly used pesticides in the state of Ohio. The chemicals are listed in alphabetical order of the trade name. Some of the more common brand names are also listed. Contact your agricultural chemical dealer for a copy of the material safety data sheet (MSDS) for verification of the information listed here or if you are unable to locate a particular chemical.
