A placard is required for a combustible liquid at what quantity?

A placard is required for combustible liquids when the quantity exceeds 110 gallons. This requirement is based on the guidelines set forth in the Department of Transportation (DOT) regulations, which categorize combustible liquids and specify the conditions under which placarding is necessary.

When transporting combustible liquids in bulk, it's essential for safety reasons to clearly mark the vehicle or container with the appropriate placard. The volume threshold of 110 gallons is established to help ensure that emergency responders and personnel can quickly identify the potential hazards in the event of a spill or accident. By placarding at this quantity, the transportation industry can maintain a higher standard of safety and preparedness when dealing with hazardous materials.

Smaller quantities, such as those below 110 gallons, do not necessitate placarding under the current regulations. Therefore, understanding this threshold helps ensure compliance with safety regulations while also facilitating effective response measures in emergencies.
