SO2 vs. H2S: Which is more toxic?
Friday, June 25th, 2010I noticed that API-14C recommends monitoring of 2-ppm (and higher) SO2 levels. I felt this was a really low threshold value for SO2 . What surprised me further is that the Immediately Dangerous to Life or Health (IDLH) value for SO2 is 100-ppm...same as H2S! Intuitively, I did not think SO2 was as toxic ...
Indoor Dispersion: A Simple Model To Estimate Indoor Concentrations
Wednesday, June 9th, 2010While evaluating impact of a toxic release, you may be interested in how the concentration of the toxicant increases in a room and its impact on indoor personnel. For example, if there is a H2S release in the plant and you want to estimate the increase in concentration in a nearby ...
Quantitative Risk Assessment: Will Quantifying Risks Help You Minimize Them?
Wednesday, August 19th, 2009How would you answer the following question: Is refinery A safer than refinery B? I know a few of you would recommend quantifying risks in each refinery. This will enable us to estimate how many fatalities (on-site and off-site) can occur in the two refineries. We can thus use the predicted ...
LNG Regasification Facilities: Consider High Pressure Releases
Sunday, April 26th, 2009LNG import terminals in the U.S. follow NFPA-59A and 49CFR193 standards for facility siting. As a part of the siting studies, LNG regasification facilities report thermal radiation exclusion zones and flammable vapor exclusion zones: Flammable vapor hazard zones are based on a design spill from a single accidental source, usually a ...
Building Facility Siting: Relocate, Replace, or Reinforce?
Sunday, April 5th, 2009Process and portable building siting has attracted further interest following the BP Texas city incident. Because of the proximity of office buildings to chemical processes, it is likely that people inside of a building be subjected to higher risks from process hazards than outdoor personnel. A facility siting study is used ...
How to Estimate Injury or Potential Fatality from Thermal Radiation Exposure?
Sunday, March 1st, 2009While performing consequence modeling we are often required to evaluate damage to population and property from a fire. Thermal radiation impact to humans from a fire should be based on the dosage – i.e. the intensity of exposure and the duration of exposure. Furthermore, such an impact from thermal radiation on ...
EPA RMP
Sunday, February 8th, 2009Under Section 112(r) of the Clean Air Act, the Chemical Accident Prevention Provisions require facilities that produce, handle, process, distribute, or store certain chemicals to develop a Risk Management Plan (RMP), and submit it to EPA. The following presentation provides a brief overview of EPA RMP. [slideshare id=389818&doc=epa-rmp-regulations-1210041888596002-9&w=425] Starting 2009, EPA RMP ...
