The Reality of Plants Where Chemical Management Is Still Paperwork
When we visit a manufacturing site and ask for the chemical inventory, we rarely receive a single file. Purchasing has a spreadsheet of purchase orders, production has a line-by-line material list, and the EHS officer keeps a folder of scanned SDS documents. Cross-checking the three often reveals a 20-30% discrepancy in the number of substances.
The causes of these mismatches are fairly predictable.
The gap usually surfaces during an incident or an inspection. When an inspector asks which process used the substance, when, and in what quantity, spreadsheet-based management takes days to answer—because the usage history was never recorded in the first place.
What Regulations Actually Require: Submission, Posting, Training, Records
Under Korea's Occupational Safety and Health Act framework, chemical management obligations fall into four categories.
SDS preparation and submission applies to manufacturers and importers, who must file with the Minister of Employment and Labor — in practice through the submission system operated by KOSHA. Sites that merely *use* chemicals are not subject to submission but must keep, post, and provide training on SDS. This distinction is a frequent source of confusion.
The trade secret alternative disclosure system requires prior approval when a company wants to withhold component identity or concentration. Approvals carry an expiration date and require renewal tracking—a deadline easily missed in spreadsheet management.
GHS labels must be affixed to containers and packaging, and inspections frequently cite the omission of *decanted* containers. A 20L transfer can drawn from a 200L drum without a label is a finding.
Training records must be traceable by substance and by worker. Inspectors typically ask when a specific operator handling a specific substance received training; a department-level group training log alone is difficult to defend.
Without a pre-review process for newly introduced substances, risk accumulates. If hazard classification, required PPE, storage conditions, and incompatibility with existing substances are not verified at the point of purchase, they get discovered only after an incident.
The Data Model to Design Before You Digitalize
The most common reason chemical digitalization projects fail is scoping them as an "SDS file upload system." Building a document repository alone leaves the inventory consistency problem untouched.
We recommend a three-layer separation.
Connecting these three layers to purchase orders structurally reduces inventory gaps. When a new item is ordered, the system checks whether a substance master record exists and routes unregistered items through EHS approval. The key principle is that anything purchased is automatically brought under management.
SDS should be managed as versions, not files. Revision history, revision date, and reason for revision belong in dedicated fields, and when a manufacturer issues a revision, the departments handling that substance should be notified. Setting automatic alerts 90 and 30 days before trade secret approval expiry prevents missed renewals.
Tangible Gains from MES and EHS Integration
Once chemical data connects to MES, compliance work becomes operational data.
In real deployments, the two to three weeks typically spent preparing the annual release inventory report can be reduced to a matter of days.
A Phased Rollout for Small and Mid-Sized Manufacturers
Many projects stall because they attempt everything at once. We recommend three phases.
Phase 1 — Inventory reconciliation (1-2 months): Consolidate purchasing, production, and EHS records into a confirmed list of substances actually in use. This phase requires no system, and it is where missing SDS documents surface.
Phase 2 — Document digitalization (2-3 months): Build the substance master, SDS version control, label printing, and training record management.
Phase 3 — Usage history integration (3-6 months): Connect to MES work order and equipment data to automatically collect process-level consumption records.
There is no need to replace an existing MES or ERP. In most cases, building a separate compliance module and integrating BOM, purchase order, and work order data through APIs is the better path in terms of both cost and risk.
