01

Define the traceability unit

A delivery note identifies a shipment, but may not identify where each supplied group was installed. Before replacement, agree whether the record will distinguish compartments, rows or another practical location unit. Use the actual equipment drawing and preserve its revision.

Retain supplier identifiers

Record the bag specification, supplier reference, delivery batch and available inspection documents. Keep unresolved identification issues visible before the materials are mixed. Do not infer identical material construction from equal dimensions or similar appearance. This is a purchasing and maintenance record recommendation, not a new material specification.

03

Connect replacement history to observations

Record installation date, affected locations and whether the work covered all bags or only part of a compartment. EPA notes that fabric-filter behavior depends on operating conditions [2]. A location and batch record helps organize later observations but does not, by itself, prove a manufacturing defect or a service-life claim.

04

Preserve changes rather than replacing history

Keep earlier location maps when bags are moved or replaced. Link returned samples and photographs to their original positions, where known, and mark uncertainty where the position was lost. The archive’s maintenance theme [1] becomes more useful when every later assessment can identify the actual supplied group.

05

FAQ: Is the purchase order enough?

It identifies the commercial order, but installation locations and partial replacements may need a separate record.

06

FAQ: Does one damaged bag condemn a batch?

No. Assess the observation with location, handling and operating history before drawing that conclusion.
