When the collected dust is determined to be hazardous special filtration and protection must be incorporated into the industrial vacuum cleaner to meet exacting standards.
But, what standards? Trying to digest the various classifications and standards for HEPA filters and Industrial Vacuum Cleaners for hazardous and toxic materials can be challenging. Many Filters in BVC Vacuum Cleaners are manufactured by a leading Worldwide filter manufacturer, and when we recently asked them to confirm the current standards they use for the HEPA filters they supply to us, gave us the following answer:-
“There are essentially 2 types of test that we use for our HEPA filters. The first is BS3928 the Sodium Flame Test. We use this for all our nuclear grade filters as it is specified in the nuclear filter standards and is the test used for all filters supplied to the MOD. The standard is now 50 years old and is likely to be reviewed in the next year or so, however the basic method, test and validation criteria are unlikely to change.
Then there are the DOP tests which are carried out on all our other, non nuclear grade HEPA filters. The standard test specification for these has been BS EN 1822 which was published in 2010. Parts of this have now been superseded by ISO 29463 from 2018. However part 1 of 1822 is still valid, this being the section that covers the classification, the nature of the performance testing and filter marking. ISO 29463 deals with the test apparatus, test procedures and how the results are interpreted and is, in effect, identical to BS EN 1822 but is designed to be a world standard rather than limited to the UK and Europe. This is particularly relevant to us in light of the Brexit.”
Relating to the two current filter tests and standards are two British standards concerning Vacuum Cleaners for hazardous dusts: BS 5415-2.2:Supplement No. 1:1986 describes “Type H” vacuum cleaners and relates to BS3928 and BS EN 60335-2-69:2012 which introduces “H-Class”, relates to BS EN 1822. Helpfully, another standard; BS 8520-1:2009 describing the correct use of vacuum cleaners for handling asbestos states that “Class H vacuum cleaners are commonly referred to as H‑type vacuum cleaners”, indicating machines complying with either standard are appropriate.
All the standards have the same objective – to ensure that Vacuum Cleaners used for hazardous dusts have high performance filtration capable of efficiently filtering tiny particles measuring a fraction of a micron.
A Vacuum Cleaner with a HEPA filter is not automatically classified as Type-H or H-Class; further tests are required on the whole machine before the classification can be confirmed.
