  • Landfill gas explosive for global warming

    In response to EPA’s 1991 landfill rules that pushed the industry to larger facilities, landfill operator’s today pile and compact trash on the ground into giant mounds in the shape of a four sided pyramid. As originally contemplated, these mounds of trash were encased in liners to keep the wastes dry so contaminants would not be mobilized to leak into groundwater, along with ...


  • 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 ...

  • 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, ...

  • 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 ...

  • Biochar‐mediated reductive transformation of nitro herbicides and explosives

    Biochar, a subset of black carbon produced via pyrolysis of biomass, has received much attention in recent years due to its potential to address many important issues, from energy and climate to agriculture and environmental quality. Biochar is known to influence the fate and transport of organic contaminants, although its role has been generally assumed to be as an adsorbent. In this study, ...

  • Measurement of Explosive Residues from Munitions and Armaments by Isocratic HPLC

    The government and the military have spent millions of dollars on making millions of tons of explosive materials. Most of these materials are warehoused in storage depots and often-present problems with leaking containers and contamination of the surrounding environment. Some are still used for testing and need to be checked for residual contamination and combustion efficiency. The industrial ...

  • A Tale of Two Sites - Enhanced Bioremediation of Explosives Impacted Soils

    The problem with OE compounds in soil A variety of organic explosive (OE) compounds have been used for military, geological and industrial applications throughout North America, and in most industrialized nations. During their manufacture, formulation and storage, these compounds have migrated to the soil. Compounds such as 2,4,6-trinitrotoluene (TNT), hexahydro-1,3,5-trinitro-1,3,5-triazine ...


  • Reliable explosion protection in an oil tanker vapor recycle plant – Case Study

    In-situ gas analyzer monitor oxygen in real-time Project The world-class transshipment and storage facility Kiire, Japan, contains 46 million barrels of crude oil in 57 storage tanks, an amount equal to Japan’s two week demand. Continuous loading and unloading of oil tankers generates odorous gases and additionally results in losses of volatile ...

  • Explosion Proof UV Lights for Commercial and Industrial HVAC systems

    In the past decade, more and more people have been installing UV lights in their HVAC systems to eradicate harmful bacteria. A timely study from Duke University Medical Center has proven the effectiveness of using UVC bands to disinfect a myriad of dangerous microbes, including drug-resistant bacteria, such as Acinetobacter, Clostridium difficile and vancomycin-resistant enterococci (VRE). During ...
