By R. Post –Since the re-discovery of regenerative energy sources wood processing has seen a considerable growth due to the demand of easy to handle fuel. In view of the ignitability and explosibility of the developing wood dust provisions must be taken to minimize/prevent the impacts of dust explosions.

By M. O’Brian – After emptying a powder from a plastic drum into a metal hopper, a spark occurred when the operator removed the drum, igniting the dust distributed in the air. The following paper presents an explanation about the “why” and “how not” of this accident. Continue reading Static Electricity Hazards – Dust Cloud Ignition caused by Static Electricity
West Lafayette (IN), USA – An increase in grain dust explosions were reported in the U.S. at grain handling, feed manufacturing and biofuel facilities in 2018; however, resulting injuries and fatalities were down from the previous year, according to an annual report issued by Purdue University’s Department of Agricultural and Biological Engineering. Continue reading The Number of Dust Explosions in the USA increased in 2018, Injuries and Fatalities decreased
By L. Williams – For a great many reasons, the conveyor belts used to convey coal or other bulk materials are highly unlikely to be suitable for carrying biomass. Sadly some very expensive lessons are already being learnt. Here Les Williams of Dunlop Conveyor Belting discusses the essential and very specific characteristics that biomass-carrying belts must have in order to perform safely and efficiently. Continue reading Belts for Conveying Biomass – The Safety and critical Importance of Conveyor Belt Technology
Ratingen, Germany – IEP Technologies recently introduced the IFV and IFV-M Isolation Flap Valves. These self-actuating devices are cost effective, easy to install, and reliable. Used in a wide range of industries where dust hazards may exist, such as food, wood processing, power generation, chemical, pharmaceutical and plastic, isolation flap valves are designed to provide explosion protection between process vessels such as dust collectors and cyclones.
Zug, Switzerland – Effective February 1, 2018, IEP Technologies, a member of the HOERBIGER Group, has acquired business operations, the portfolio, patents and trademark rights of Atexon Oy, a company headquartered in Oulunsalo, Finland, specializing in spark detection and extinguishing for industrial explosion protection. Continue reading IEP Technologies acquires Spark Detection Specialist Atexon
Only a small time window exists for successful explosion mitigation.
First there is the shock wave, then follows the flame: Time is of the essence when it comes to preventing a catastrophe after an undesirable ignition has taken place inside a plant prone to explosions. What exactly is involved in this process, and how can risk be averted? IEP Technologies, the explosion protection expert within the HOERBIGER Group, explains the critical phase of a dust explosion and how reliable suppression and isolation systems can save lives. The most important realization is that the first 75 milliseconds are crucial. A comparison with a blink of a human eye, which lasts an average of 100 milliseconds, demonstrates just how little time this is.
