Diazinon (CAS 333-41-5): storage and disposal

Because it is old stock, leave it where it stands and report any leaking, damaged or failing container for specialist assessment. Check that it is upright, on a tray or in a contained area, and away from watercourses and food, and it must never reach a drain. Keep it separate from feed, veterinary medicines and other agricultural chemicals. A metal can that has rusted through or a plastic drum that has split is a risk. Do not decant it into a newer container. Record the location, the number and size of containers, and the label wording. An old store that floods, or sits near a yard gully, is a concern because of the aquatic classification, so mention that when enquiring.

The container is the evidence here. Look for rust and corrosion on metal cans, bulging or cracked plastic drums, stained or peeling labels, crust or staining round the cap, wet patches on the floor under the container, a lid that has seized and a smell in the store. It gives few other visible signs, so nobody should open a container to look inside. Faded or lost labels are common on this stock. A container with a damaged seal, an unreadable label or no date should be recorded and reported, not moved or opened.

We arrange this by specialist collection. We do not publish a drain or general waste route for any chemical. It is normally packed in a general laboratory pack with compatible chemicals.

What must not be done is the first thing to say: nobody should open it, pour it out, dilute it, or put it down a yard drain or a sink, and an old dip tank or drum is not emptied to make collection easier. Record each container by size, material, label wording and condition, and whether it is leaking. Its usual codes are 16 05 06* generally and 18 02 08 for a veterinary setting. The paperwork follows the confirmed waste classification and the applicable requirements for the material. A store assessment is sensible for leaking or corroded containers, and the carrier packs sound ones in compatible groups.

Usually held as: legacy sheep dip.

Tell us the container size and how many you hold. An estimate is enough to start with, and some items cannot be priced until someone has looked at them.
