Full title and description

STB VDI 2263 Blatt 6: Staubbrände und Staubexplosionen – Gefahren – Beurteilung – Schutzmaßnahmen – Brand- und Explosionsschutz an Entstaubungsanlagen (English title: Dust fires and dust explosions — Hazards — Assessment — Protective measures — Dust fires and explosion protection in dust extracting installations). This VDI guideline provides requirements and practical guidance for assessing hazards and implementing protective measures against dust fires and dust explosions in dust extraction and dust collection systems.

Abstract

VDI 2263 Blatt 6 (2017-08) addresses the assessment of hazards and selection of protective measures for dust fires and dust explosions occurring in dust-extracting and dust-collection installations. It covers conditions under which combustible dust/air mixtures, vapour/air mixtures or hybrid mixtures can form, and gives guidance on risk assessment, zoning, explosion prevention and mitigation, fire protection, and measures specific to filtering and separation equipment. The guideline is intended to support designers, manufacturers and operators in meeting the state of the art for explosion protection in these systems.

Scope

The guideline applies to measures for explosion and fire protection in dust extraction / dust-collection systems where, during intended operation, combustible dust/air mixtures, vapour/air mixtures or hybrid mixtures may be present or can form. It covers risk assessment methodology for separators and filters, selection and application of protective measures (prevention, explosion isolation, suppression/venting, ignition source control), and practical recommendations for planning, operation and maintenance of dust-handling installations.

Key topics and requirements

• Risk assessment for dust fires and dust explosions in dust extraction equipment (filters, separators, ducts).
• Identification and evaluation of combustible dusts, hybrid mixtures and potential ignition sources.
• Definition of hazardous zones and guidance on likelihood of occurrence as a function of zoning.
• Preventive measures: process design, material handling, housekeeping, filtering choices to minimise dust accumulation.
• Protective measures: explosion isolation, explosion suppression/relief/venting, fire detection and extinguishing, and safe layout of plant.
• Equipotential bonding / earthing recommendations to prevent electrostatic ignition.
• Guidance specific to filtering separators and examples illustrating application of measures (annexes and examples provided in companion document VDI 2263 Blatt 6.1).
• Integration with applicable normative references and regulatory context for plant operators and designers.

Typical use and users

Used by process and plant engineers, safety engineers, equipment manufacturers, operators of dust-producing processes, maintenance teams, EHS professionals, and notified bodies or authorities assessing compliance. Typical applications include design and retrofit of dust collection systems, preparation of explosion protection documents, zoning and ignition-source control, and selection of explosion protection equipment and layout measures.
