A potentially explosive atmosphere could be generated by the equipment during its intended use. It covers equipment driven by electricity and by pneumatic power.This document deals with all significant hazards, hazardous situations and events relevant to vacuum cleaners when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer.Typical applications for the concerned equipment are:- Collection of dust produced by machinery at the point of generation;- General housekeeping around machinery and of working areas; and/or- Collection of spills.For other specific applications, a specific assessment willl be performed.This document does not cover equipment used to collect toxic dusts where there is a health risk if dust passes through the filter elements. This document does not cover either the collection of dusts which have explosive and unstable properties (UN transport class 1, class 4.1 and class 5.2).This document covers vacuum cleaners with an internal dirty air volume of max. 250 l.This document does not apply to vacuum trucks.This document does not apply to applications where the material is conveyed into a separate receiving container.This document does not apply to Group I vacuum cleaners for mining.For an easier readability, all types of equipment concerned by this document are referred as “Vacuum cleaner”.
