What is the definition of ignitability in the context of hazardous waste?
-
The ability of a waste to catch fire and burn easily.
-
The ability of a waste to produce toxic gases when burned.
-
The ability of a waste to corrode metal.
-
The ability of a waste to react violently with water.
A
Correct answer
Explanation
Ignitability is the ability of a waste to catch fire and burn easily. This property is important because it can pose a fire hazard if the waste is not properly managed.
What is the flash point of a hazardous waste?
-
The temperature at which the waste will catch fire.
-
The temperature at which the waste will boil.
-
The temperature at which the waste will produce toxic gases.
-
The temperature at which the waste will react violently with water.
A
Correct answer
Explanation
The flash point of a hazardous waste is the temperature at which the waste will catch fire.
What is the boiling point of a hazardous waste?
-
The temperature at which the waste will catch fire.
-
The temperature at which the waste will boil.
-
The temperature at which the waste will produce toxic gases.
-
The temperature at which the waste will react violently with water.
B
Correct answer
Explanation
The boiling point of a hazardous waste is the temperature at which the waste will boil.
What is the vapor pressure of a hazardous waste?
-
The pressure exerted by the vapor of the waste at a given temperature.
-
The pressure exerted by the liquid of the waste at a given temperature.
-
The pressure exerted by the solid of the waste at a given temperature.
-
The pressure exerted by the gas of the waste at a given temperature.
A
Correct answer
Explanation
The vapor pressure of a hazardous waste is the pressure exerted by the vapor of the waste at a given temperature.

-
The temperature at which the waste will catch fire without an external source of ignition.
-
The temperature at which the waste will boil.
-
The temperature at which the waste will produce toxic gases.
-
The temperature at which the waste will react violently with water.
A
Correct answer
Explanation
The autoignition temperature of a hazardous waste is the temperature at which the waste will catch fire without an external source of ignition.
What are the three main categories of ignitable hazardous wastes?
-
