Full title and description

STB VDI 2263 Blatt 8-1 2011-03 — Dust fires and dust explosions - Hazards - assessment - protective measures - Fire and explosion protection on elevators - Examples. This part of the VDI 2263 guideline collection provides practical examples for risk analyses and protective measures specifically for elevators (vertical conveyors) where combustible dust/air, steam/air or hybrid mixtures may occur.

Abstract

Part 8.1 presents worked examples, forms and explanatory material to support manufacturers and operators in conducting hazard assessments and implementing preventive and protective measures for dust fires and dust explosions in elevators. It complements the main guideline VDI 2263 Blatt 8 by illustrating application of the principles, constructional measures, fire-fighting considerations and example assessments (including an example for a bucket elevator conveying oil seeds).

Scope

This guideline applies to measures for fire and explosion protection in elevators (vertical conveyors) used for bulk materials where, in normal operation, combustible dust/air mixtures, steam/air mixtures or hybrid mixtures can arise. It is intended to support both manufacturers (design and construction) and operators (risk assessment, operation and maintenance) by providing example assessments and recommended protective measures; familiarity with VDI 2263 Blatt 8 (the main elevator guideline) is assumed.

Key topics and requirements

• Worked examples for performing hazard and risk assessments specific to elevators and bucket conveyors.
• Illustrative constructional and preventive measures for explosion protection in elevator systems (e.g., design to limit dust accumulation, access restrictions, material selection).
• Guidance on integration of protective systems (venting, suppression, isolation) appropriate to elevator installations.
• Fire-fighting and emergency measures tailored to vertical conveying equipment and enclosures.
• Annexes with a form for hazard assessment and a full example assessment (bucket elevator conveying oil seeds) to demonstrate application.

Typical use and users

Used by equipment manufacturers, plant designers, safety and process engineers, maintenance supervisors, facility operators and insurers. Typical uses include early-stage design reviews, preparation of risk assessments (explosion protection documents), operator training, verification of constructional protective measures, and as reference examples when implementing explosion prevention and mitigation measures for vertical conveyors in industries handling dusty bulk materials (agro-food, chemicals, minerals, wood products, etc.).

Related standards

Closely related to other parts of the VDI 2263 series (notably VDI 2263 Blatt 8 — Fire and explosion protection on elevators, and VDI 2263 Blatt 8.2 — explosion suppression and combinations of structural measures for elevators). It is also frequently considered alongside national and international documents on dust explosion protection and venting (examples referenced in vendor listings include VDI 2262 series, VDI 3893, EN 14491 and other relevant EN and DIN/VDI rules).
