LEV / Dust Extraction Learning

LEV / Dust Extraction Learning

LEV / Dust Extraction Learning

Hi All,

I'm normally a provider of answers on the Safety Relief Valve Forum.

For my sins, I am now employed in the Dust Extraction Industry. This not a student request by any means. The company I now work for has a unique automated system that can be applied to existing dust extraction systems, and works by closing and opening individual pick up points on demand saving substantial energy costs for fan operation. Thus I want to gain knowledge on the bigger picture of LEV.

Can any of you experts in the LEV field advise on any good material, in the form of books, papers etc., for me to study in order to bring myself up to a reasonable level? I am based in UK, but my company is involved globally.

I am particularly interested in basic design od Dust Extraction (like woodworking), what is required to know, understand etc., and of any particular codes and standards used in this field.

Thanking you for any advice.

My go to reference for everything having to do with industrial Ventilation is
ACGIH: Industrial Ventilation Manual
by American Conference of Governmental Industrial Hygienists
You can read it here https://archive.org/details/gov.law.acgih.manual.1...
or purchase it here https://portal.acgih.org/s/store#/store/browse/det...

ACGIH has some related training available from their website https://www.acgih.org/

in the US the prescriptive OSHA code is 29CFR1926.57 - Ventilation. But meeting the prescriptive code does not assure meeting required exposure limits (TLV). That is where engineering comes in to play.

You will want to look carefully at the discussion about transport velocity if transporting combustable dusts like sawdust is part of your business.

Many Thanks FacEngrPE - That info will get me on my path.

*** Per ISO-4126, the generic term 'Safety Valve' is used regardless of application or design ***

*** 'Pressure-relief Valve' is the equivalent ASME/API term ***
