Final answer:
A waste class 3 material (flammable liquid) can be exempt from the specification packaging requirements if it meets certain conditions.
Step-by-step explanation:
According to the Hazardous Materials Regulations (HMR), a waste class 3 material (flammable liquid) is NOT subject to the specification packaging requirements if packaged in certain conditions:
- The chemical in the waste must be unused.
- The chemical in the waste must be in the form of a commercial chemical product.
By meeting these conditions, the waste class 3 material can be exempt from the specification packaging requirements of the HMR.
