NFPA 82 - Crematoriums

Posted by ericnette Employee Jun 17, 2015

A frequent question I get here is whether or not NFPA 82 covers crematoriums under the definition of an Incinerator. Let's look at the definition of an Incinerator:


"3.3.7* Incinerator.    Equipment predominantly designed for burning solid waste."


In the standard we do not define "solid waste". Therefore the definition of waste falls to Merriam-Websters Collegiate Dictionary.


"4 a :  damaged, defective, or superfluous material produced by a manufacturing process: as (1) :  material rejected during a textile manufacturing process and used usually for      wiping away dirt and oil <cotton waste> (2) :  scrap (3) :  an unwanted by-product of a manufacturing process, chemical laboratory, or nuclear      reactor <toxic waste> <hazardous waste> <nuclear waste>

     b :  refuse from places of human or animal habitation: as (1) :  garbage, rubbish (2) :  excrement—often used in plural (3) :  sewage"


Most of the AHJ that I speak to do not classify Human or Animal remains as waste.

The next edition of NFPA 484, Standard for Combustible Metals, is open for public input until July 6th, 2015. To submit a public input using the online submission system, select NFPA 484 from the Document information pages (list of NFPA codes & standards) . Once on the NFPA 484 document information page, select the link "The next edition of this standard is now open for Public Input" to begin the process.  You will be asked to sign-in or create a free online account with NFPA before using this system.


The First Draft meeting for the document is scheduled for August 25th to 27th at Oak Ridge National Laboratory in Knoxville, TN.  One goal of the committee at the first draft meeting is to work towards correlating 484 with the new NFPA 652 standard, Fundamentals of Combustible Dusts.  Additional details on the meeting can be found on the document information page for NFPA 484.


NFPA 58 - Important Building

Posted by ericnette Employee Jun 17, 2015

How do you classify an "Important Building" for separation distances in Chapter 6 of NFPA 58? In the standard we don't define this term, and leave it up to the AHJ.


I do have a couple reasons some AHJ's have declared some buildings are an "Important Building":

1. Replacement Value

2. Human Occupancy

3. Value of the Contents

4. Vital Role in the function of the Business or it's Records

5. It's role in Emergency Operations

NFPA 52 Reorganization

Posted by sbershad Employee Jun 17, 2015

The Vehicular Alternative Fuel Systems technical committee has been working on a complete reorganization of NFPA 52, the Vehicular Gaseous Fuel Systems Code.  This code covers both compressed and liquid natural gas fueled vehicles.  These vehicles have seen increased use over the past several years, particularly in fleet usage.  Natural gas is a clean burning fuel, creating less carbon dioxide emissions than gasoline or diesel.  The new edition, just finishing up second draft now, will be simpler and easier for the user, grouping material common to both fuels together, and then listing supplemental requirements for each fuel.  The new edition will be published in 2016.
