Requirements for design and testing of vacuum cleaners and dust collectors for use in potentially explosive atmospheres
|Publication Date:||1 January 2019|
|ICS Code (Cleaning appliances):||97.080|
This document specifies requirements for design, construction, testing and marking of hand-held, portable and transportable vacuum cleaners and dust collectors, including their accessories, constructed to Group II categories 2G and 3G and to Group II categories 2D and 3D, intended for the collection of combustible or non-combustible dusts and flammable or non-flammable liquids in potentially explosive atmospheres. A potentially explosive atmosphere may 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 and dust collectors, 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 shall 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 element.
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 dust loaded volume of maximum 200 l.
This document does not apply to pumps, where the inlet nozzle is submerged into a liquid, and all conveying applications.
This document does not apply to Group I vacuum cleaners and dust collectors for mining.
For an easier readability, all types of equipment concerned by this standard are referred as "Vacuum cleaner" in this document.
NOTE Collecting dust is recognized as a suitable action in view to participate to prevention against explosion.
