I’ve Completed My DHA–Now What?

Another great article byChris Giusto with Hallam-ICS I’ve Completed My DHA–Now What?April 9, 2019
Once your DHA is complete, you will have a list of hazards that require implementing additional protective measures.  As discussed in my last blog, 7 Steps to Complete a Dust Hazard Analysis (DHA),  important steps must be taken after this list is generated, or the DHA will be for naught. I touched on these as steps 5 through 7 in that article, and here I will explore them in more detail.

A great article byChris Giusto at Hallam-ICS 7 Steps to Complete a Dust Hazard Analysis (DHA)April 9, 2019 This blog outlines the process of completing a Dust Hazard Analysis (DHA) as required by NFPA 652.  The term DHA is often used interchangeably with the “analysis” portion of the processes (Step 4 below), but a complete DHA process involves additional steps before and after the analysis.

It is critical to recognize that just completing the analysis does not make your facility any safer without appropriate follow up actions (Steps 5 through 7 below).  My next blog, “I’ve Completed My Dust Hazard Analysis, Now What?” will explore these steps in greater detail.

A great article byChris Giusto at Hallam-ICS A Practical Guide to 5 Important Properties of Combustible DustsApril 9, 2019 In a previous blog, Combustible Dust Fundamentals and NFPA 652, I mentioned having your dust tested to determine important properties that are critical for protecting your personnel and facility.

These properties are used in calculations for designing and sizing protective devices like vent panels and isolation valves.  They are also important to understand during your Dust Hazard Analysis (DHA) to properly identify hazards.  (You can learn more about DHAs in my previous blog What is a Dust Hazard Analysis (DHA)?)  This blog will discuss five of the primary properties you must know to identify, understand, and m…

A great article byChris Giusto at Hallam-ICS What is a Dust Hazard Analysis (DHA)?April 9, 2019 In my last blog I discussed Combustible Dust Fundamentals and NFPA 652 and explained some of the background as to why NFPA 652 requires a Dust Hazard Analysis.

This blog will explain what a DHA is, and answer some other common questions about them.
What is a DHA? A Dust Hazard Analysis (DHA) is a systematic review of the processes and areas of your facility where combustible particulate solids are present.  (Figure B.4.5 below from NFPA 652 shows how an example process is broken down into individual points to be evaluated.)  The analysis will help identify the fire, flash-fire, and explosion hazards that exist in your facility.  The DHA will…

A great article byChris Giusto at Hallam-ICS Combustible Dust Fundamentals & NFPA 652April 9, 2019 With the compliance deadline for completing a Dust Hazard Analysis (DHA) less than two years away, and existing requirements already in place, it is a good time to revisit the “new” NFPA 652 Standard on the Fundamentals of Combustible Dust.

Approved as an American National Standard on September 7, 2015, this standard is “new” only relatively speaking.  While many in the combustible dust safety community knew about it while it was still being developed, and were glad to see it implemented, there remain plant managers, EHS professionals, and plant engineers three years later that still do not understand what is required of them.  Re…

Towards Compliance: NFPA 652 Standard on the Fundamentals of Combustible Dust

From out friends at OHS Online, and Vahid Ebedat
Towards Compliance: NFPA 652 Standard on the Fundamentals of Combustible Dust If explosion preventive measures alone cannot reduce the risk of a dust cloud explosion to an acceptable level, then explosion protection measures must be considered. By Vahid EbadatMay 01, 2019 Explosible dust clouds can be expected at some point during any powder/dust handling, transfer, processing, dust collection, or packaging operation. Of course, if there is an ignition source present, a dust deflagration or explosion may occur. It is clearly essential that effective precautions are taken to control the risk and protect employees, contractors, the public, and the facility against the effects of fires and explosions.
Over the past few decades, the National Fire Protection Association (NFPA) has published a number of codes and standards to help industry with its efforts to assess and control dust fires and explosions. Although very useful, the…

What Plant Manager Needs to Know About Combustible Dusts

From our friends at Fauske:
5 Things Every Plant Manager Needs to Know About Combustible DustsPosted byZachary Hachmeister on 05.08.19 By Zachary Hachmeister, Chief Operating Officer, Fauske & Associates, LLC
Combustible Dust is Fuel
This may sound obvious, but it’s really important. You need to think of dust deposits on surfaces or dust leakage from equipment as uncontrolled fuel in your facility. This, of course, is only true for dusts that are combustible. The reason this is so important is that it will help shift you and your employees’ perspective on dust from a nuisance that reflects a lack of cleanliness to a potential hazard that is putting you, your co-workers, and your assets at risk. (This slight shift in perspective can translate to an increased awareness of combustible dust hazards and by doing so, can help you identify where dust is escaping from your proce…
