  • Safe Drain® Saves My Facility From Accidental Spill

    "I am writing to thank-you for a great product. This morning we had a 25 gallon diesel spill near our Vehicle Service Area. The spill was a fluke - from the tank of a truck that was parked on a gradient - left without a gas cap. Diesel poured out of the truck onto the asphalt - directly into a newly installed Spill Safe Drain that was closed tightly. All of the spilled product was recovered, ...

  • Coupled solution of oil slick and depth averaged tidal currents on three-dimensional geometry of Persian Gulf

    Abstract: In this paper, simulation of oil spill due to tidal currents in Persian Gulf is performed by coupled solution of the hydrodynamics equations and an equation for convection and diffusion of the oil. The hydrodynamic equations utilized in this work consist of depth average equations of continuity and motion in two dimensional horizontal planes. The effect of evaporation is considered in ...

  • Impact of heavy metals on the oil products biodegradation process

    Oil products continue to be used as a principal source of energy. Wide-scale production, transport, global use and disposal of petroleum have made them major contaminants in prevalence and quantity in the environment. In accidental spills, actions are taken to remove or remediate or recover the contaminants immediately, especially if they occur in environmentally sensitive areas, for example, in ...

  • Compensation for natural resource damages from oil spills: a comparison of US law and international conventions

    The basic measure of natural resource damages in USA environmental liability statutes is the cost of restoring the injured resources, plus compensation for the interim loss of resources from the time of injury until their full recovery. In contrast, until 1996, the international Convention Protocols addressing liability for accidental oil spills did not hold the responsible party liable for ...

  • Soot level – a diesel engine lube oil condemning limit

    While there is widespread disagreement on used-diesel oil condemning limits, it is well known that excessive soot in the lube oil causes abnormal valve and injection-train wear.  It can also increase exhaust emissions and clog filters.  Typically, the suggested limit for soot is in the neighborhood of 3% but can go much higher.  With the new ASTM Method D7686, truck, bus, ...

  • Hazardous chemicals and proper storage solutions

    Many acceptable categorical storage schemes have been proposed and used by laboratories in academic, industrial, government and medical institutions. The common features uniting all these plans is the separation of incompatible materials. The differences in these various storage schemes arises in the number of groups that should be established for segregation purposes. The ten most commonly cited ...

  • Ultrasonic technology in cooling towers

    Ultrasound technology is an effective and environmentally friendly method to minimise chemical consumption and improve the efficiency of a cooling tower, says Ander Paz Blazquez. Low-intensity ultrasound has been used for more than a decade in order to control algae and biofilm growth. Latest innovations have concluded that effective algae control is achieved through the use Ultrasound ...

  • Photo‐induced toxicity of Deepwater Horizon slick oil to blue crab (Callinectes sapidus) larvae

    The 2010 Deepwater Horizon oil spill resulted in the accidental release of approximately 700 million L of crude oil into the Gulf of Mexico. Photo‐induced toxicity after co‐exposure to ultraviolet (UV) radiation is 1 mechanism by which polycyclic aromatic hydrocarbons (PAHs) from oil spills may exert toxicity. Blue crab are an important commercial and ecological resource in the Gulf of Mexico, ...

  • Development of short, acute exposure hazard estimates: A tool for assessing the effects of chemical spills in aquatic environments

    Management decisions aimed at protecting aquatic resources following accidental chemical spills into rivers and coastal estuaries require estimates of toxic thresholds derived from realistic spill conditions: acute pulse exposures of short duration (h), information which often is unavailable. Most existing toxicity data (median lethal concentration or median effective concentration) come from ...

  • Hygiene facilities vs Safety Showers

    Health and Safety guidelines surrounding hazardous substances and decontamination can often be vague. Guidelines often recommend the provision of ‘hygiene facilities’ or ‘washing facilities’ to ensure potentially harmful substances are removed before a worker moves on to another task or finishes work for the day. However, an ordinary shower or sink is not always enough to ...

  • The Missing Link in Bacteria TMDLs: Natural Growth

    INTRODUCTIONFecal indicator bacteria (FIB), including total coliform, fecal coliform (or E. coli), and Enterococcus, have long been used to indicate the contamination of fecal matters in beaches, streams, and lakes (USEPA, 1986, 2002). When the bacterial concentration in a waterbody exceeds the FIB water quality criteria, the waterbody may be identified on the Clean Water Act Section 303(d) list ...
