What color is typically associated with flammable materials on a placard?

The color that is typically associated with flammable materials on a placard is red. This color is universally recognized as a warning sign that indicates the presence of a fire hazard. Red placards effectively communicate the danger posed by flammable substances, alerting first responders and others to take caution. The use of red is consistent with other safety protocols and regulations, making it an essential aspect of hazard communication in the context of handling hazardous materials.

In contrast, other colors used for placards may represent different types of hazards, such as blue for health hazards, yellow for reactive materials, and green for specific safety instructions or non-hazardous substances. Understanding these color codes is crucial for ensuring safety during the transport and handling of hazardous materials.
