Type 11 applies only when this condition holds: cyanides are used in the process.

Quenching bath sludge from oil baths in non-precious metal heat treating where cyanides are used. Oily and cyanide bearing.

Is B.C. Type 11 hazardous waste?

Yes, when the Schedule 7 description and definition conditions are met. Type 11 is a listed B.C. hazardous waste with a Schedule 7 shipping name. The waste must match the entry's description and stay inside the hazardous-waste definition after exclusions.

For a regulated listed-waste shipment, Type 11 is the shipping name on the B.C. hazardous waste manifest. The B.C. exclusions and shipment rules apply.

What does B.C. Type 11 cover?

Type 11 covers cyanide heat-treatment oil-bath sludge. It applies only when cyanides are used in the process. It is a B.C. listed-waste shipping name. It is not a TDG class, and not a general code for similar material from another process.
