Final answer:
Scales for weighing DOT cylinders with LP-gas capacity of less than 101 pounds must be registered with state agencies involved in weights and measures. The exact agency may vary by state, but ensuring correct calibration and standard adherence is essential for safety and compliance with both state and federal regulations.
Step-by-step explanation:
Scales used to weigh DOT (Department of Transportation) cylinders with an LP-gas (liquefied petroleum gas) capacity of less than 101 pounds must be registered with specific state agencies, which can vary depending on the state. The regulation of these scales falls under state jurisdiction, often managed by the state's department of weights and measures or a similar regulatory body. This is because accurate weighing of DOT cylinders is crucial for safety, transportation, and commerce reasons. The regulations for hazardous materials, including the weighing of LP-gas cylinders, need to comply not only with state-level requirements but also with federal regulations such as those enacted by the United States Department of Transportation and the Environmental Protection Agency (EPA).
Registration of scales is important as it ensures calibration to the correct standards and adherence to safety practices. Although the exact state agency responsible for registration can differ, businesses and individuals dealing with DOT cylinders should check with their local and state regulations to ensure compliance. Proper registration and regulation of these scales help to prevent accidents and maintain the integrity of the transportation system.
