Which position in the NFPA 704 system represents flammability?

In the NFPA 704 system, flammability is represented by the position colored red, specifically found at the second position in the numerical system of the diamond-shaped label. The scale for flammability ranges from 0 to 4, where 0 indicates materials that will not burn and 4 signifies materials that can ignite easily at normal temperatures.

The correct answer points to the fact that the second position in the NFPA hazard signal identifies flammability and uses this specific color-coding to help responders quickly assess the risk associated with a hazardous material in the event of an emergency. Understanding this system is critical for safe handling and effective response to hazardous materials incidents, as it helps responders to prioritize their actions based on the dangers presented by the material.

Confidence in utilizing these symbols enables emergency personnel to minimize risks while managing incidents involving flammable substances effectively.
