A yellow marking on an NFPA label indicates which type of hazard?

Health hazard
Instability hazard
Flammability hazard
Biological hazard

The correct answer is: Instability hazard

A yellow marking on an NFPA (National Fire Protection Association) label is used to indicate an instability hazard. The NFPA labeling system employs a color-coded system with a diamond shape that contains four quadrants. Each quadrant is used to represent different types of hazards: health, flammability, reactivity (or instability), and specific hazards. The specific quadrant for instability or reactivity is represented by yellow. This marking signifies the degree to which a material may react with other substances or be sensitive to heat, pressure, or shock. A higher number in the yellow quadrant indicates a greater level of instability, which is crucial for emergency responders to know when dealing with hazardous materials. Understanding the significance of these color codes is vital for safety protocols and emergency response procedures, ensuring that personnel can quickly assess the risks associated with various materials during incidents.
