CLAKS

Requirements for Hazardous Substance Management

In research facilities, in-house laboratories, and production areas, chemical inventories are constantly changing: new substances are procured, quantities fluctuate, and responsibilities shift due to projects, shift work, or personnel changes. Without centralized tracking, containers can end up without clear accountability, leading to duplicate orders and gaps in documentation. At the same time, Section 6(12) of the German Hazardous Substances Ordinance (GefStoffV) requires that the hazardous substances inventory be kept up to date at all times. Violations of the GefStoffV or REACH can result in fines.

CLAKS addresses these requirements in a centralized software solution and keeps the hazardous substances inventory, stock levels, and responsibilities continuously up to date.

Integrated Substance Database

CLAKS comes with a pre-populated substance database: over 244,000 substances and over 81,000 validated GHS classifications, updated annually. The database includes, among other things, H- and P-phrases, storage classes, occupational exposure limits, and registration numbers. Current safety data sheets from manufacturers are directly linked.

This saves time when creating containers and prevents serious errors—substances need to be manually created and classified only in exceptional cases.

Data Sovereignty Through On-Premises Operation

CLAKS is operated exclusively on-premises within your own IT infrastructure. Substance data, structural formulas, and research results remain within your network.

Resilience

As an on-premises solution, CLAKS operates independently of external data centers and cloud services. Even in the event of outages by external providers or internet connection failures, CLAKS remains available within your own network. The software is therefore designed for organizations with high security requirements—particularly operators of critical infrastructure (KRITIS) and security-critical research.

Container History

Each container is tracked via barcode or QR code from order placement through disposal and is assigned to a workgroup and a responsible employee at all times. Before placing an order, CLAKS displays existing internal inventory—this prevents duplicate purchases.

Key Figures

• 244,000+ substances pre-loaded
• 81,000+ GHS classifications
• 30+ years of experience
• 100% on-premises

Efficiency: CLAKS handles recurring data entry and documentation tasks—from substance entry and the provision of safety data sheets to label printing in accordance with the CLP Regulation.

Compliance: The hazardous substances inventory pursuant to Section 6(12) of the German Hazardous Substances Ordinance (GefStoffV) is continuously updated, and inventories are reconciled with requirements from the REACH Regulation and the German Chemicals Act. Operating instructions, data for risk assessments, and analyses to support internal controls or regulatory audits can be provided in a structured manner directly from the system. This reduces the amount of preparation required for regulatory audits. For management, this means that demonstrably fulfilled organizational obligations reduce liability risk.

Integration: Integration with existing ERP systems such as SAP is possible, for example, for inventory reconciliation and budget approval.

Experience: CLAKS was developed on the initiative of the University of Hamburg and has been further developed by LCI Systems GmbH for over 30 years. The software is in use at numerous universities, research institutions, and industrial companies.
