What is a characteristic of ignitable hazardous waste?

The characteristic of ignitable hazardous waste is that it has a flash point below 60 degrees Celsius. The flash point is the lowest temperature at which a liquid can form an ignitable mixture in air, meaning that at or above this temperature, the substance can easily catch fire if an ignition source is present.

Materials with a flash point below 60 degrees Celsius are considered hazardous because they can ignite at relatively low temperatures, posing significant risks in environments where such materials are stored, handled, or disposed of.

In contrast, a flash point above 60 degrees Celsius indicates that the material is less likely to ignite under normal conditions, and materials with a flash point below 10 degrees Celsius would be extremely volatile and dangerous. Non-toxic waste may not necessarily be ignitable, as it refers specifically to the absence of toxic properties, rather than to the material's flammability. Therefore, identifying ignitable hazardous waste hinges on the flash point categorization, making the correct answer about the threshold of 60 degrees Celsius.
