Which type of hazard does a red placard generally indicate?

A red placard is typically associated with flammability hazards. This designation is part of the National Fire Protection Association (NFPA) labeling system and is crucial for emergency responders to quickly assess the risks present. The coloration of the placard helps indicate the level of danger posed by materials in terms of their ability to catch fire or explode when exposed to heat, sparks, or flames.

The specific use of red signifies that the material is capable of igniting easily and can contribute to hazardous situations, making it vital for safety protocols during handling and transportation. Recognizing these indicators is essential for anyone involved in dealing with hazardous materials, ensuring they take the necessary precautions to mitigate risks associated with flammable substances.
