  • NEC Classifications and Divisions for Hazardous Locations

    Electrical equipment in hazardous (classified) locations present a serious threat for workers due to the existence of explosive dust and vapors. Examples of such facilities range from grain mills and gasoline stations to aircraft hangars and chemical manufacturing plants. To prevent devastating explosions that may occur from the ignition of combustible particles in the atmosphere, the National ...

  • Explosion Proof Lights and Hot Environments

    Fixtures that are exposed to high ambient temperatures are prone to failure and malfunction. In industrial facilities with high lighting consumption rates, this is can be a complex issue to address, especially in hazardous locations where explosive dust and vapors are present. As a solution, establishments may apply explosion proof metal halide and incandescent fixtures with external ballasts. ...

  • Reducing the risk of dust explosion hazards

    In the wake of recent tragic and highly publicized dust explosions, companies are asking, 'Could that happen here?' and 'What can I do to prevent such an incident at my facility?' One approach is to manage dust explosion hazards as though they were subject to OSHA’s Process Safety Management (PSM) requirements (29 CFR 1910.119), even though dust hazards often are not covered under this ...

  • When are Oil Wells an Explosive Hazard?

    Contrary to popular belief, an oil well can be an explosive hazard even when it is not in operation (pumping steady). An EnergyWire review of federal labor statistics cited that the oil and gas sector experiences the most deaths from fires and explosions, compared to other private industries. Risks of Explosive Elements around Oil Wells A recent explosion in ...

  • Explosion Proof vs Intrinsically Safe Gas Detectors

    It only takes a spark to start a fire or cause an explosion, especially when flammable gases or vapours are present under the right conditions. There are industries that operate in these types of hazardous environments where the potential for explosions is extremely high, such as chemical plants, oil refineries, paint shops, cleaning facilities, tanks and loading facilities for flammable gases, ...

  • How To Avoid Dust Explosions In Your Baghouse

    A massive fire and explosion in the dust collection system of a New Hampshire wood pellet manufacturer demonstrates the need for adequate system design to prevent combustible dust explosions in general industry.  We recently published a news article on Environmental-Expert.com about OSHA’s enforcement actions concerning last year’s combustible dust fire and explosion at the ...

  • A Cost-Effective Approach to Explosion Consequence Modeling

    Failure to identify and mitigate explosion hazards is a persistent cause of industrial accidents, impacting sites ranging from fertilizer storage facilities to refineries. While some explosion consequence assessments are performed to comply with regulatory requirements or industry-specific process safety standards, in many cases the potential for loss of life and property damage is overlooked ...

  • How a wet dust collector can prevent a violent explosion (and more!)

    Explosive dust is a major concern among metal finishing operations, and recent changes in the National Fire Protection Association regulations have made compliance more difficult. Metalwork grinding and sanding produces a fine metallic dust that, even after being filtered from the air, can smolder, catch fire, or even explode violently if it’s exposed to a spark. Aluminum, lithim, ...

  • Incineration of Explosives-Contaminated Soil and Reactive RCRA Waste at the Former Weldon Spring Ordnance Works

    ABSTRACT This paper presents the results of a Combustion Risk Assessment (CRA) and Trial Burn Testing Program for a transportable hazardous waste incinerator at the former Weldon Spring Ordnance Works (WSOW), Missouri, USA. From 1942 to 1945, the Ordnance Works was the largest TNT manufacturing plant in the world, producing approximately 1 million pounds of TNT per day. The Transportable ...

  • Re-examining the health effects of radiation and its protection

    The health effects of radiation from atomic explosions in Japan were completely different from those due to radiation from the Co-60 contaminated apartments in Taiwan. The sudden exposure to acute radiation in extremely high doses killed Japanese people, and harmed the survivors in lower doses as shown by increased cancer mortality, especially the leukemia based on the LNT model. The chronic ...

  • Selecting and Placing Gas Detectors for Maximum Application Protection

    Many industrial processes involve dangerous gases and vapors: flammable, toxic, or both. With the different sensing technologies available, and the wide range of industrial applications that exist, selecting the best sensor and locating them properly for the job at hand can be a challenge. To ensure a high level of safety, know the latest sensing technologies, which technology is best for the ...

  • Dynamic analysis of glass curtain walls with protective films subjected to blast loading

    Recent terrorist events have underscored the importance of designing glass curtain walls as engineered systems. Glass panels which shatter in the explosion produce high velocity fragments, the cause of majority of injuries in such incidents. Glass curtain walls with protective films have proven to be well suited for use in glazing systems that resist blast loading. The rectangular glass plates ...

  • A review of layer of protection analysis techniques for oil and gas industry

    The paper indicates advantages (and disadvantages) of layer of protection analysis (LOPA) over other methods to support its paramount position among different process safety analysis (PSA) methods in use today. Its simplicity (using order-of-magnitude estimates for all elements that constitute an accident scenario), universality (easy adaptation to particular needs), directness to indicate the ...

  • Fire and Gas Protection Systems as Part of Safety Instrumented Systems and Risk Management

    Garth Watkins, Director Europe, Middle East, Africa, Detector Electronics Corporation, Presented at HazardEx International Conference 2008 Process-systems operators today face increasing demands for lower costs and higher safety standards in an increasingly regulated environment. In addition, companies desire to provide a working environment that is as safe as possible. As a result, plant owners ...

  • Role of DNA protection and repair in resistance of bacillus subtilis spores to ultrahigh shock pressures simulating hypervelocity impacts

    Impact-induced ejections of rocks from planetary surfaces are frequent events in the early history of the terrestrial planets and have been considered as a possible first step in the potential interplanetary transfer of microorganisms. Spores of Bacillus subtilis were used as a model system to study the effects of a simulated impact-caused ejection on rock-colonizing microorganisms using a ...

  • Lighting the way for disinfection - Case study

    Pharmaceuticals manufacturing involves the handling of powders and volatile, flammable solvents such as iso-propanol. Consequently there is every opportunity for explosive atmospheres to form. Where this is the case, the Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR) require that new equipment and protective systems must be selected on the basis of the requirements set ...

  • A user–layered approach for modelling and simulating terrorist attacks

    Modelling and simulation techniques offer a comprehensive method for assessing the impact of a terrorist attack, allowing multiple scenarios to be simulated with ease without imposing extensive time or cost constraints. The aim of this paper is to provide a comprehensive model for the different categories of users who are likely to be involved in the modelling and simulation of a terrorist ...

  • Combustible Dust: It Doesn’t Take Much

    A dust accumulation of 1/32 of an inch deep—about the thickness of a dime—covering just five percent of a room’s surface area doesn’t sound like much, but it’s enough to cause a catastrophic explosion, according to the National Fire Protection Association (NFPA). Although good engineering and safety practices to prevent dust explosions have existed for decades, there ...
