Which of the following is a characteristic of hazardous materials?

A characteristic of hazardous materials includes properties that can pose a risk to health, safety, or the environment. Explosive materials are classified as hazardous due to their potential to cause sudden and violent reactions, which can result in injury, property damage, or environmental harm. This volatility and capability for rapid energy release are key factors that distinguish explosives as hazardous.

In contrast, materials that are inert, non-reactive, or neutral are generally considered to pose limited or no hazards in typical scenarios. These properties suggest stability and a lack of immediate dangerous reactions, which do not align with the characteristics fundamentally associated with hazardous materials. Therefore, explosive materials are clearly recognized as a dangerous category within the spectrum of hazardous materials, making it the correct identification in this context.
