Keep the original container
Product identity and label information should stay with the material while it is stored for disposal.
Do not improvise disposal
Do not pour products into drains, onto the ground or into other containers unless the responsible local authority or product information specifically directs it.
Use local collection programs
Municipal or regional household hazardous-waste programs are the appropriate place to check accepted materials and drop-off procedures.
Avoid accumulating excess products
Buying only what is likely to be used reduces future storage and disposal problems.
General household information only. Follow product labels and manufacturer instructions. Electrical, gas, structural, hazardous-material and other safety-critical work belongs to appropriately qualified professionals.
