The intent of a dust hazard analysis (DHA) is to identify potential process operations (normal and upset) that could lead to fires and explosions. To successfully accomplish this goal, owner/operators must establish a credible basis of safety that removes one or more of the elements of the combustible dust explosion pentagon. Control of ignition sources is a credible basis of safety. However, many DHAs overlook the wide variety of ignition sources that are not electrical or electrostatic in nature.
This presentation will describe a disciplined approach that identifies potential electrical and non-electrical ignition sources when conducting a DHA, including an appropriate focus on mechanical equipment ignition sources. Topics to be covered include:
- Global approaches to identifying ignition sources, based on EN 1127-1:2019, “Explosive atmospheres – Explosion prevention and protection”
- Common electrical & electrostatic ignition source
- Common mechanical equipment ignition sources & scenarios
- Basic method for conducting a Mechanical Equipment Ignition Risk Assessment (MEIRA)
- How to integrate ignition source analysis into a comprehensive DHA.

This webinar will talk about problems with a feeding device that result from how the material is handled in the associated bin and the relationship between the device controlling discharge and the vessel from where the material is supplied.
Often a feeding device is evaluated independent of the feed bin supplying material. When a problem arises, a deficiency in the feeding device is assumed. Yet in many cases, these issues may result from what is taking place with the material in the bin above. This webinar addresses some of the more frequent feeder issues that often result from the storage of material in the feeder's associated storage vessel.

Many products created today are a mixture of several components, each with a unique purpose in the product design. Processing operations in the production or packing facilities, as well as customer handling of point-of-use products, can result in segregation. Regardless of the reason, segregation observed by the end-user is always a problem for the manufacturer. What can production and packing facilities do to mitigate segregation of their product? An intriguing question is: Can an understanding of bulk flow properties be coupled with simple lab scale segregation measurement to predict and quantify the expected segregation in a process or bulk handling system? Can segregation be mitigated by changes in the process or does it also require changes in the product? This webinar addresses the issue of process-based segregation using a systematic approach based on sound scientific principles.
Segregation prevention based on process changes requires knowledge of several things. The solution of segregation from a process point of view is all about velocity control in the process vessels. First, it is necessary to understand how the basic bulk flow properties effect the velocity profile in the process. Second, how to effectively measure the segregation pattern and magnitude in a lab scale test must be known and understood. Finally, it is necessary to combine the velocity profile in the process with the segregation profile and magnitude so as to determine what effect the whole handling system and/or packing process might have on the enhancement or mitigation of segregation in the process. Once this is understood, steps can be taken to modify the process to reduce or eliminate the segregation.
Sometimes fixing segregation problems requires modification of the process. The trick is to know what things about the process are causing the lion's share of the segregation problems and fix those things.
Attend this webinar and learn:
- Key flow properties that relate to predicting velocity and velocity profiles in process equipment
- Segregation measurements and how segregation might occur in process vessels during normal handling
- How to use flow properties to predict velocities in process equipment and couple these velocity profiles with segregation patterns to mitigate segregation in the process
- How to modify the process to prevent segregation in the plant or packing facility
- Examples of real-world segregation issues and their solutions.
The people that will benefit from this discussion will be process engineers, plant managers, quality assurance engineers, design engineers, and product formulators.

The NFPA is making significant changes in the combustible dust standards by combining them into a new code called NFPA 660. This will be the new single source standard/code for combustible dusts and their associated compliance issues. One of the major components for the fundamentals and commodity chapters (food, metals, chemical, wood) is combustible dust compliance for dust collection systems. This webinar will seek to explain what combustible compliance means for those companies with dust collection systems handling combustible dusts regarding the requirements of the fundamental chapters and for each of the major commodity chapters of the new 660 code.
Osborn has 45+ years-experience in the concept, design, project management, start-up, and operations/maintenance for an extensive range of mechanical equipment systems, including dust collection, ventilation, bulk handling mechanical systems (pneumatic and mechanical), storage, weighing, mixing, batching, etc. He is also a member of all six NFPA committees on combustible dusts (61, 484, 652, 654, 664, and Correlating).

Screening/separation technology operates 24/7 with little or no attention. When screens/separators are down, cleaning, sanitizing, and maintenance functions must take place rapidly and effectively. The webinar begins with an overview of screening/separation technology in the food and ag industry and specifically how screening/separation equipment is cleaned, sanitized, and maintained. In practice, operations, cleaning, sanitizing, and maintenance functions are frequently compartmentalized. Separation of these functions may not achieve best results. Interweaving of operations, cleaning, sanitizing, and maintenance can save time and money and enhance product safety.
Strategies to interweave these functions will be introduced and discussed. Brief case studies will be presented to illustrate the concept of interwoven operations, cleaning, sanitizing, and maintenance activities.

In process facilities, the risk of an industrial explosion always exists. The risk can be reduced or minimized with proper deflagration protection; either administrative or engineered. However, for that protection to be optimally effective it should be based on genuine experimental data. This data may be readily available for gases and vapors. Explosibility data for dusts are commonly sample-specific and not material-specific. Thus, data for the actual process dust is required. The data may have been previously generated during a safety review. But often safety reviews overlook the added complexity of a hybrid mixture (dust in the presence of gas/vapors). In a hybrid mixture the vapor from a solvent or a process gas can exacerbate the explosion severity and ignition sensitivity of dust. If these considerations were neglected during the Dust Hazards Analysis (DHA) then the explosion protection schema may be insufficient to mitigate the hazard because it relied only on dust cloud explosibility data.
Attend this webinar and learn:
- Factors to consider for protecting against hybrid dust explosions
- Nuances in testing that can skew the data

In this webinar, we will discuss feeder design and the importance of knowing your material’s flow properties. Knowledge of solids flow properties is very important when you are designing bins and hoppers to ensure reliable flow. However, remember that the feeder design is of equal importance and solids flow properties information is critical to proper feeder design as well.
We will discuss your material’s physical and environmental properties along with how to interpret a flow report that details your material’s arching and ratholing dimensions, bulk density, and friction properties. This will include how these properties effect your feeder design whether you use a screw feeder, belt feeder, rotary valve, or a vibratory pan feeder.
Marinelli is a bulk materials handling expert who has taught hundreds of highly acclaimed engineering seminars. Since 1972, he has been active in testing bulk solids and consulting on materials handling systems design. Marinelli worked with Dr. Andrew Jenike (who is recognized worldwide for his work in bulk solids handling), for many years. He received his Bachelor of Science degree in Mechanical Engineering, from Northeastern University in Boston, MA.
Marinelli lectures frequently, teaching courses on solids flow principles and flow property testing and has authored several papers and an encyclopaedia section on the subject.

One of the significant contributors to production downtime and quality issues is segregation (or separation) of material blends during processing. Therefore, it is critical to understand and control segregation in process equipment. This webinar will address this issue using a systematic approach using sound scientific principals as a guide.
Segregation prevention based on in-process blending requires knowledge of several things. First, an understanding of how easily measured flow properties can/will influence the velocity and velocity profiles in process equipment. Second, an understanding of how to measure the segregation pattern and magnitude for the material placed in a given process. Finally, an understanding of how combining information about velocities and velocity profiles with segregation patterns can enhance (or mitigate) segregation present in the system. To fix a segregation problem, information regarding the velocity of material in the process equipment must be matched with the expected segregation profile or pattern. Some velocity profiles increase segregation, and some velocity profiles decrease segregation as material leaves handling systems. The trick is to know what velocity profile will help with a material’s unique segregation behavior.
