Certified Hazardous Materials Manager (CHMM) Practice Exam

Question: 1 / 400

Which characteristic is used to define a waste as hazardous?

Decomposition

Non-reactivity

Ignitability

A waste is defined as hazardous based on several key characteristics, one of which is ignitability. This characteristic refers to the ability of a material to catch fire easily and sustain combustion. Wastes that can ignite under certain conditions or have a flash point below a specified temperature are categorized as hazardous due to their potential to cause fire hazards.

By emphasizing ignitability as a criterion, regulatory frameworks, such as the Resource Conservation and Recovery Act (RCRA) in the United States, highlight the critical nature of managing substances that can pose immediate risks to public safety and the environment. Other factors like toxicity, reactivity, and corrosivity also help define hazardous wastes, but ignitability serves as a key indicator of potential danger, particularly in waste disposal and storage scenarios.
