ASSE Submits Comments on Proposed Combustible Dust Legislation

The American Society of Safety Engineers submits comments on proposed combustible dust legislation. You can read the entire article at the link above.

Among their recommendations: a more organized, comprehensive approach by OSHA is needed to facilitate compliance. ASSE’s primary concern is that an answer to the current difficulties involving combustible dust risk management be based on sound science and done in a way that affords all stakeholders due process, without any undue delay.

In Chemical Design, written by our friends at Farr, a good article for those in the chemical processing and other industries, on current explosion venting requirements:

Chemical Design | Get Up-to-Date on Explosion Venting Requirements | Chemical Processing

Operations in many chemical plants can pose the risk of dust explosions. One common potential source of such explosions is a dust collection system. It’s therefore timely to examine the latest complete revision of the “National Fire Protection Association (NFPA) 68 Standard on Explosion Protection by Deflagration Venting” to see what’s changed and how this impacts future dust-collection decisions. The standard, which can be purchased online via the NFPA web site ( ), applies to all closed-vessel dry-collection systems such as cartridge-style dust collectors. So, here, we’ll share our understanding of five key implications of NFPA 68 as they relate to cartridge dust-collection systems.

1. NFPA 68 has changed from …

Combustible Dust Explosions and Fires-ATEX: Wood Pellet Dust Fire Non-Issue?

Combustible Dust Explosions and Fires-ATEX: Wood Pellet Dust Fire Non-Issue?

This was originally posted by John Astad at

Combustible dust should be a major source of concern in process industry, and especially in the new bio-fuels industries that do not have historical experience with fire and explosion prevention. When you are drying, grinding, pulverizing, conveying, and compressing wood flour (or other organic material), you are creating the perfect storm for a combustible dust fire or deflagration. Every time you move or manipulate product in the process you are creating combustible dust. Then all you need is an ignition source for combustion. Ignition sources are plentiful in the drying, grinding and pellitizing stages. And it is very easy to convey a spark or ember into a combustible dust cloud within the pellet cooler, dust collector, and storage bin. These small fires they are currently experiencing in the bio-fuels industries are warning signs, sim…

How Fireproof Is Your Workplace?

Here is a good article from our friends at Safety Daily Advisor on fire hazards in the workplace. 

Many times while touring plants I  notice many of the common fire hazard issues listed in this article, especially layers of combustible dust on the ground and on machinery, along with other combustible materials and ignition sources.

On an average day, there are more than 200 workplace fires in this country. Annually, those fires kill hundreds of workers, injure many thousands more, and cost American businesses billions of dollars in damage and lost productivity.Unfortunately, there are dozens of ways workplace fires can start. You have to be on top of potential fire hazards all the time to make sure that your facility doesn't become part of the statistics.

Possible Increased Combustible Dust Explosions Due to the Increased Industrial Use of Nano Powders?

The interesting thing about nanopowders is the particle size and surface area, making them appear at first glance potentially highly combustible similar to vapor cloud or hybrid mixtures, but they also tend to agglomerate. Particle size, shape, charge, concentration, humidity etc. all affect agglomeration. Consequently, agglomeration (and de-agglomeration in testing) can throw off combustible testing results!  Another interesting note is that the finer the particle, the lighter and higher it will travel and settle, so dust collection (and therefore protection - fire, explosion and personal) becomes even more important.
On our Linked-In network The Combustible Dust Forum, Robert Dumbrowski at Nanoview Associates asked the following question:Possible Increased Combustible Dust Explosions Due to the Increased Industrial Use of Nano Powders?

What is a ComDust Hazard?

Different sources report that 70 - 80% of process dust and fines are combustible, depending on the process and material variables.  Keys are understanding your process hazards, the combustibility of your material and fines.  But remember, processes are not static. Processes and materials change over time.  Education, hazard awareness, testing, training, process design, controls, maintenance, housekeeping, policies and procedures are keys to long term process safety.

Inferno: Dust Explosion at Imperial Sugar

YouTube - Inferno: Dust Explosion at Imperial Sugar
Shared via AddThis


This is a very instructive video and case study from the US Chemical Safety Board entitled: Inferno - Dust Explosion at Imperial Sugar.  While this video pertains to sugar dust, it applies to most any combustible dust application.  The Imperial Sugar plant used many of the same processes and machinery used in many process industries, such as grinding and milling, belt and screw conveyors, bucket elevators, dust collectors and storage silo's.   

This video explains in detail how process, conveying, dust collection, housekeeping and safety system design, or lack of, all impacted the fires and explosions in this process - that killed 14 workers, injured dozens of others, and shut the plant down for an extended period of time.  This tragedy exposes the critical need in our process industries for inherently safe design along with housekeeping, proper safety systems design and training.

Safety Pros Are Not Expendable

ASSE Prez: Safety Pros Are Not Expendable DES PLAINES, IL -- In his address this week to attendees of the Canadian Society of Safety Engineering's Conference in Calgary, Alberta, ASSE President C. Christopher Patton, CSP, discussed how safety, health and environmental professionals are weathering the difficult economic times and how businesses could lose productivity, efficiency and profitability without their expertise. [full story]

Take Heed

Take heed. The CSB US Chemical Safety Board has finalized their report on the Imperial Sugar disaster, and concluded that the combustible dust explosions and consequential injuries and loss of life were preventable. While we do not necessarily believe all explosions are preventable, we do believe this report characterizes the sate of industry in this country. European countries have long implemented ATEX standards as law for preventing fires and explosions in process industry. In the United States, we have had current best engineering practices, NFPA and FM Global standards for preventing these type incidences for decades, but many in industry have ignored them, unless prompted by OSHA or their insurance company. This attitude gets people hurt. It opens your company up to lawsuits and affects your reputation in your community, industry, and with your customers. I have had many mangers tell me they have run their plants for years with no incidences of fires. Many ti…

Sawdust Fire Difficult to Extinguish

Sawdust fires can indeed be hard to fight. First you are dealing with a very combustible product. Second it is conveyed to a dust collector with all the ingredients for a fire and deflagration. All that is needed is a spark to complete the Fire Triangle. As per NFPA 664, a listed Spark Detection & Extinguishing System in the conveying system is a very effective tool in preventing this type of fire. Third, saw dust is typically stored in a silo or bin with enough volume that it is hard to extinguish any embedded embers or fires not matter how good your sprinkler or deluge system, because the water will tunnel through the material instead of wetting it thoroughly and consistently. And fourth, with enough combustible dust disbursed within the vessel, as you empty it you create an increasingly explosive atmosphere . Firefighters are at risk of injury when opening a dust collector or storage vessel as they are adding oxygen to a combustible dust cloud with an embedded embe…

Sugar Case Gets Hearing

Imperial Sugar is finally getting back up and running. A tragedy that should never have happened. Adequate and properly engineered dust control systems, dust collection, controls and interlocks, systems and procedures, safety equipment, and housekeeping can prevent most if not all combustible dust fires and explosions. Fire prevention is both a science and an attitude. It must come from the top down.

OSHA continues crackdown on combustible dust hazards

A good article from our friends at Wood & Wood Products magazine on the continuing and stepped up OSHA Combustible Dust hazard inspections, and what it means for your plant. Repeat violations are being levied with large fines. For wood dust, the most cost effective protection is a listed Spark Detection & Extinguishing System to prevent fires and explosions in the incipient stage. With the addition of sprinkler and deluge systems, explosion vents, and an abort gate on any return air systems, you will typically be well covered.

From our friend Dr. Saraf with the Risk & Safety Blog, comes another excellent brief, this time on Expanding Vapor Explosions. This is not on our usual topic of combustible dusts fire & explosion prevention, but is relevant for our customers in many industries we deal in. BLEVEBLEVE stands for Boiling Liquid Expanding Vapor ExplosionIf a tank containing liquid is subjected to external fire, the heat from the fire lead to boiling of the liquid. This in turn leads to increased pressure in the tank. This “boiling” liquid and “expanding” vapor may increase the pressure significantly and cause the tank to rupture. If the released liquid is flammable , it can catch on fire resulting in a fire and explosion.The following video demonstrates the BLEVE

Recent Recycling Plant Explosions

Recent Recycling Plant Explosions

In reference to combustible dust and in the wake of recent recycling plant fires and explosions, we need to increase awareness of combustible dust hazards in the recycling process industry.

We have protected many types of recycling plants in many industries. Many forms of recycling plants including paper, wood, rubber, aluminum, lead, even batteries and tires, etc. often create combustible dust as a byproduct, similar to their parent primary manufacturing processes. We have even helped protect military installations where they were grinding everything from paperwork to munitions! However the recycling industry can be as, or even more hazardous because of the nature of the byproducts from recycling, as well as the creation of sparks from fractioning recycled materials. Of course any time you have fugitive dust it is typically conveyed to a dust collector containing the comdust and oxygen, two of the three main ingredients to the fire triangl…

Leading Indicators to Improve Safety Programs

Using Leading Indicators to Improve Your Safety Program
By Terrie S. Norris, CSP, ARM, CPSI
Terrie S. Norris is the risk control manager for Bickmore Risk Services & Consulting.
How are you measuring the success of your safety program? Many entities, whether private or public, use one or more of the following: OSHA incident rate, severity rates, claims per $100 in payroll, number of fatalities, average cost per claim, and/or experience modification. These are all great trailing indicators. The problem is that they are measures of failure. A loss must occur before a value can be established. An analysis of the losses may provide a focus for the entity’s safety and health or its liability programs, but it does not drive improvement.
A better equation for the improvement of safety, health, and liability performance is focused attention on leading indicators plus measured performance. Leading indicators are those that focus attention on activities that can contribute to i…

Dust Characteristics and Venting

Collecting and Testing Dust
Knowing dust characteristics facilitates ventilation equipment selection
By Lee Morgan, Farr APC

In 1998, both the Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health (NIOSH) issued more stringent requirements relating to the use of respirators in plants. Though respirators are critical to shielding workers from ambient dust and fumes, they are not the total answer.
The new OSHA standard (29 CFR 1910.134) states that employers are expected to use engineering controls to protect workers from air contaminants and not rely on respirators alone. While respirators do a good job of protecting workers' lungs, they do nothing to safeguard machinery and process areas from contamination that may result in costly equipment failure, constant rework, or general cleaning nuisances.
The equipment currently used in fabricating plants has reached a new level of sophistication. High-definition plasma cutters, lase…

Clarifies Dust Explosion Venting Requirements for California

Jupiter, FL (OPENPRESS) June 9, 2009 -- Recent projects in California uncovered a concern that may be unique to that state. Since similar concerns had been raised in previous California projects international dust explosion protection leader, CV Technology was motivated to clarify dust explosion requirements specific to the state of California.During a recent risk analysis for dust explosion hazards at one of the largest food processing plants in California, several vessels that handle combustible dusts were found to be unprotected.
The client required verification of compliance with applicable NFPA Standards, and if shortfalls were found, the client required recommendations for rectification. In this particular facility all of the vessels requiring protection were indoors and it would be quite straight forward to protect them using explosion vents ducted to the outside.

Safety Forecast for the 21st Century
May 24th, 2009 by Dr. Saraf
The 20th century was a time of great technological change that forever transformed how we live and work – changes that necessitated the birth and development of the field of Process Safety Management. The early years saw the evolution of mechanization into assembly lines and true industrialization. Lack of access to South American nitrate during World War I, led to the creation of the synthetic chemical industry. World War II fostered increased industrial growth and sophistication. By the 1960s, we were building computers and beginning our race to the moon. Industries grew becoming increasingly sophisticated and reliant on automated systems. The 1970s brought the creation of the US EPA and OSHA. The 1980s witnessed one of the greatest tragedies in the last century – an estimated 4,000 people died in the 1984 Bhopal accident. Since then, the process safety community has evolved in its approaches and methodologies to better …

Good Housekeeping – Minimize Accumulation of Combustible Dust
Cleanliness in the workplace may be subjective among your employees. OSHA requires good housekeeping, as 29 CFR 1910.22 indicates, “All places of employment, passages, store rooms and service rooms shall be kept clean, orderly, and in a sanitary condition.”
However, if your organization contains combustible dust hazards, one of the best methods to avoid the potential for a combustible dust explosion is to enforce good housekeeping rules. This is not subjective. NFPA 654 warns that a dust layer >1/32 of an inch accumulated on surface areas of at least 5 percent of a room’s floor area presents a significant explosion hazard. The Chemical Safety Board found that the West Pharmaceutical explosion in Kinston, NC in 2003 was caused by dust accumulations primarily under ¼ inch.Materials that may form combustible dust include metals (such as aluminum and magnesium), wood, coal, plastics, biosolids, sugar, paper, soap, dried bloo…

2008 Dust Explosions and Fires Overview

The Combustible Dust Policy Institute found through researching media accounts in 2008 that over 150+ combustible dust related fires and explosions occurred in the manufacturing, non-manufacturing and utility sectors in the United States. Over 30% of these incidents are repeats of prior fires and explosions that fire departments are responding to. Subsequently, these reoccurring incidents mostly go unnoticed by OSHA, unless there are at least three injuries or one fatality.
The current OSHA Combustible Dust National Emphasis Program (NEP) directive does not address the majority of national industries (NAICS) where incidents are frequently occurring. For example, over 60% of incidents in 2008 occurred in national industries not listed in Appendix D-1 and D-2 of the NEP. Too much emphasis and resources is being directed toward the OSHA Dust NEP, when the majority of incidents are occurring in national industries not referenced …
