Full title and description

VDI 2263 Blatt 6.1 (2017-08) — Staubbrände und Staubexplosionen: Gefahren, Beurteilung und 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 - Examples).

Abstract

Guidance for assessing hazards from dust fires and dust explosions in dust-extracting/filtration systems and for selecting and implementing protective measures. The document provides practical examples and complements VDI 2263 Blatt 6 by illustrating risk assessment steps, protective measures (including structural, organizational and technical measures), bonding/earthing examples and zone considerations for dust-extraction equipment. It is intended to be applied together with VDI 2263 Blatt 6.

Scope

This guideline applies to explosion- and fire-protection measures for dust extraction and filtration systems in which, under intended use, combustible dust/air mixtures, vapour/air mixtures or hybrid mixtures can be present or can form. It offers practical examples and concrete implementation guidance to support the risk assessment and the selection of protective measures for operators, designers and manufacturers; it is intended to be used in conjunction with the more principle-focused VDI 2263 Blatt 6.

Key topics and requirements

• Risk assessment methodology for dust fires and dust explosions in dust-extracting installations.
• Examples of protective measures: prevention, suppression, containment and mitigation adapted for extraction systems.
• Fire protection examples specific to filtering/separator equipment and ducting.
• Equipotential bonding and earthing examples to prevent ignition by electrostatic discharge.
• Zone classification guidance and likelihood estimation of fire/explosion events for operational scenarios.
• Practical implementation notes complementing the principles in VDI 2263 Blatt 6 (organizational and technical measures).

Typical use and users

Used by plant operators, safety and EHS managers, process and mechanical engineers, filter and dust-collection equipment designers, maintenance staff, and consultants responsible for explosion protection and fire safety in industries handling combustible dusts (e.g., food processing, wood working, metal powder handling, chemicals, pharmaceuticals). The guideline is used when performing risk assessments, designing protective measures for extraction systems, and preparing exploded-mitigation plans and documentation.

Related standards

Primary companion: VDI 2263 Blatt 6 (principles for dust fires/explosions and protective measures). The guideline should be considered alongside national and international explosion-protection standards and regulations (for example, regulatory frameworks on explosion protection and standards on hazardous-area classification and explosion safety).
