Previous contents matter when selling process equipment

Previous contents can affect how process equipment is inspected, handled and assessed for reuse. Record them before the sale, including what remains unknown.
A tank labelled “empty” may still have a relevant residue history. A pump described as “stainless” may have handled a product that matters to the next owner. The useful disclosure connects the equipment to its actual past use and available cleaning evidence.
Do not wait for a buyer's transporter to ask what was inside.
Build a factual prior-use record
Use the following headings for each asset or clearly defined process package.
Equipment identity. Give the asset reference, maker, model and serial where available. State which connected components the record covers.
Known materials. List the substances or products handled, with dates or periods where records exist. Include meaningful product identifiers and relevant supporting documents.
Source of information. Distinguish production records, purchase records, operator recollection and assumptions. Replace assumptions with “not established” in the confirmed record.
Cleaning or other work. Identify who carried it out, when and which document describes the scope. Attach the document rather than rewriting it as a guarantee.
Present uncertainty. State missing history, inaccessible areas and unresolved residue questions.
Specialist action. Record who must assess the gaps and what information they need before inspection, movement or reuse.
This is a disclosure record, not a decontamination certificate. Give it a date and the name or role of the person who compiled it.
Keep the equipment boundary clear
A record for the main vessel may not cover the pump, hoses, filters or associated exchanger. Identify what the history actually includes.
For process tanks, distinguish the vessel's contents from heating or cooling media in a jacket. For heat exchangers, record the known media on each side. Mixing those histories into a single “water system” description can conceal useful information.
A pump's past duty should include the fluid it handled, not only the motor rating. A plastics granulator needs a record of previous feedstock and known contamination issues, rather than an assumption that all material was clean production scrap.
These details help the right specialist assess the asset. They do not establish compatibility with the buyer's intended materials.
Ask a precise specialist question
Instead of asking whether a machine is “safe to sell”, provide the known history and ask what assessment is needed for the proposed inspection, preparation and movement.
HSE's work-equipment maintenance guidance for Great Britain identifies risks from flammable, explosive and toxic materials and the need for competent work. It also cautions against entering tanks and vessels without the necessary specialist arrangements.
Use that guidance to commission an appropriate assessment. Do not open equipment, enter vessels or improvise cleaning to fill gaps in a sales record.
Useful questions include whether the existing documents cover the whole package, what restrictions apply before further work, and what completion records the contractor will provide. The answers should name the actual equipment and work.
Handle confidentiality without hiding material facts
Some production details may be commercially sensitive. Agree a disclosure process with the responsible business contact or adviser. That may mean keeping customer names out of the public catalogue while providing necessary technical information through an agreed route.
Confidentiality is not a reason to describe unknown contents as harmless. If the information cannot yet be released, record that the assessment remains unresolved.
Keep safety data and technical documents in their original form. A shortened catalogue paragraph should point to the relevant records, not replace their qualifications.
Let the findings shape the sale
The assessment may affect the timetable, collection condition or appropriate sale route. Resolve those implications before making firm promises to buyers.
Send UK Auction Group the prior-use record alongside the inventory. Flag specialist work and unavailable history at the outset so the sale plan reflects the equipment's real condition and preparation needs.
