ComplyOnSiteIs Ontario 148 hazardous waste?
Not from the code alone. Ontario 148 describes the waste stream, not whether it is hazardous. Ontario decides that from the hazardous characterization or liquid-industrial status, and from the exclusions. The 3-digit class needs a primary characterization letter to form the waste number.
For subject waste, the generator enters the class-and-letter waste number in the waste details of the Ontario hazardous waste manifest. Ontario’s exclusions and shipment rules also apply.
What does Ontario 148 cover?
This is the catch-all class for inorganic chemicals that no more specific class describes. It takes discarded laboratory chemicals, surplus stock and off-specification inorganic chemicals. Acid, alkaline and other named streams have their own classes, so an unwanted chemical doesn't select this one by itself.
Is other inorganic waste chemicals Ontario 148 or another class?
| Code | When it fits |
|---|---|
| 148 | The stream is surplus, off-specification or laboratory inorganic chemicals without a specific class. |
| 263 | The discarded chemical is organic and no more specific class describes it. |
| 114 | The waste is an inorganic acid described by the acid classes. |
Find out whether the chemical is inorganic or organic, then use the named process or material class before the miscellaneous one. The 2 miscellaneous classes aren't interchangeable.
