Scope

This document specifies machinery safety requirements.

This document is applicable to thermal and catalytic cleaning systems with regenerative or recuperative preheating for exhaust gas loaded with flammable substances from surface treatment equipment.

This document deals with all significant hazards, hazardous situations or hazardous events relevant to thermal and catalytic cleaning systems for exhaust gas from surface treatment equipment, when these are used as intended and under conditions of misuse which are reasonably foreseeable.

See Annex A for significant hazards.

The specific significant risks related to the use of this machinery with exhaust gases from sources other than surface treatment equipment (e.g. from chemical production, tank farms, cremation, wastewater treatment) are not dealt with in this document.

Limits of thermal and catalytic cleaning systems for exhaust gas from surface treatment equipment are specified by the interfaces given in Figure 1.

Please see draft for Figure 1 — Limits of the machinery

This document is not applicable to

— cleaning systems without preheating of input gas;

— cleaning systems for input gas with a concentration of flammable substances higher than those specified in 4.8;

— cleaning systems for input gas containing H2 or pyrolysis gases;

— cleaning systems for input gas with a O2/N2 ratio higher than in air;

— absorptive and adsorptive exhaust gas cleaning systems;

— membrane separators;

— UV exhaust gas cleaning systems;

— filter systems;

— plasma exhaust gas cleaning systems;

— biological exhaust gas cleaning systems.

This document is not applicable to the machinery or machinery components manufactured before the date of its publication.
