Charlie,

As long as the product is certified to UL 61010-1 by a third party that is 
accepted by the AHJ, you should be fine.  You could also field label it at the 
installation site.  NFPA 79 would not be needed.  The AHJ's are typically 
looking for a third party mark.  Just make sure the third party is accepted by 
the AHJ.  OSHA NRTL does not necessarily mean local AHJ acceptance.  Many 
jurisdiction have their own rules and approval schemes for field labeling.

Ron / Jody



Product is covered by Semi S2, and 3rd party report.

We apply 61010-1 standards as the equipment is "industrial process control" - 
and will be NRTL listed.



The equipment is going to be sold into more than one jurisdiction - is 
applicability, or not, of NFPA 79 going to come down to interpretation of local 
AHJ, or is there a way I can get a definitive in/out scope decision?



regards

Charlie

You might want to ask your Customers what they require. Since your equipment 
processes semiconductor gases then SEMI S2 will most likely come into play. 
Also, depending on who your Customers are, they might require field labeling to 
comply with local OSHA requirements, and the standard mostly used in these 
cases is NFPA 79.

Subject: [PSES] Scope of NFPA 79


All



I'm trying to determine whether a product falls within scope of NFPA79 for USA.



EU Machinery Directive determines whether a product is within scope by what it 
does, but my reading of NFPA79 is that the latter also considers "what it does 
it to".



Looking at the 2015 version, NFPA79, Chapter 3, section 3.3.54  defines 
'Industrial Machinery'  as:
" A power-driven machine (or group of machines working together in a 
coordinated manner),  not portable by hand while working, that is used to 
process material by cutting; forming;  pressure; electrical, thermal, or 
optical techniques; lamination; or a combination of these  processes. Machine 
can include associated equipment used to transfer material or tooling,  
including fixtures to assemble/disassemble, to inspect or test, or to package. 
[The associated  electrical equipment, including the logic controller(s) and 
associated software or logic together  with the machine actuators and sensors, 
are considered as part of the industrial machine.]"



The product in question processes gases (in silicon wafer and flat panel 
manufacturing plants) - so I don't think it processes "material".



If that is the case, it would be outside scope of NFPA79, and just within scope 
of NFPA70. Comments?



regards

Charlie
