  • FTIR gas analysis improves container safety

    Introduction Entry to freight containers represents a significant hazard to staff responsible for inspection, stuffing or destuffing because of the large number of airborne chemicals that can be present. Research in Germany and the Netherlands found hazardous levels of gases and vapours in around 20% of all containers and this level of contamination is now accepted as commonplace. It ...

  • Mercury Analysis

    Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...

  • Forensic engineering applied to the analysis of a gas explosion in a residential building

    Present paper deals with the identification of the cause of an explosion in a hollow space positioned below a residential building as the result of welding operations. On field investigation clearly demonstrated that the explosion was due to the ignition of a flammable atmosphere in the basement of the building. Along the trial two hypotheses were brought to the judge: (a) explosion of an ...

  • Benefits of HART Communication-Enabled Gas and Flame Detectors

    Catastrophic results can occur when a fire or a flammable/toxic gas release goes undetected in any petrochemical facility. For early warning and prompt hazard mitigation, flame detectors and gas detectors are essential tools. Clear, usable, diagnostic information from these detection instruments is extremely valuable in ensuring the devices are properly maintained, tested, and poised to protect ...

  • Follow toxic gas standards for a smoother project

    Toxic gases, such as Hydrogen Sulfide and Sulfur Dioxide, can injure and kill quickly. Therefore, mitigation of these hazards must be fast and sure. The United States Occupational Safety and Health Administration (OSHA) and other authorities take detection of these gases very seriously. The American National Standards Institute/ American Petroleum Institute (ANSI/API) and ISA industry standards ...

  • 5 Reasons to Perform a Consequence Modeling Analysis for Your Facility

    The potential for accidental release of toxic chemicals to the environment is a daily threat for many industrial facilities and plants. These releases can occur very suddenly and unexpectedly, putting employees and the public at risk of injury or death, and the surrounding environment at risk of damage or destruction. A consequence modeling analysis is a powerful tool (and sometimes a regulatory ...

  • 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 ...

  • Medical Industry: Compliance Problems Solved by Ethylene Oxide Scrubber at Specialty Gas Plant Case Study

    The ethylene glycol produced in the ethylene oxide scrubbing operation acts as an antifreeze to allow year-round operation. Problem: A specialty gas producer was confronted with an EPA compliance problem in dealing with ethylene oxide (EtO). The chemical had been added to the toxicity lists of the U.S. EPA and the Occupational Safety and Health Administration ...

  • Chemical Industry: Compliance problems solved by Ethylene Oxide Scrubber at Specialty Gas Plant Chemical Industry The ethylene glycol produced in the ethylene oxide scrubbing operation acts as an antifreeze to allow year-round operation

    Problem: A specialty gas producer was confronted with an EPA compliance problem in dealing with ethylene oxide (EtO). The chemical had been added to the toxicity lists of the U.S. EPA and the Occupational Safety and Health Administration (OSHA). Effective August 21, 1984, the OSHA standard for EtO limited exposure to a 1 ppm, eight-hour time weighted average. Ethylene ...

  • Continuous measurement of Process oxygen for Claus sulfur recovery unit (sru) start-ups and shut-downs case study

    During start-up and shut-down, any time a sulfur recovery unit (SRU) transitions from ambient temperature through fuel gas warm up to the introduction of acid gas, measurement of 02 stoichiometry is critical. Historically, operators have manually taken samples using a portable electrochemical type Os analyzer. While giving more or less satisfactory results, the requirement for more stringent ...

  • 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 ...

  • Avoiding Sewer Fires with Vapor Space Organics Monitoring

    ABSTRACTRegulation of flammable gases released from wastewater discharges is facilitated by the use of the Vapor Space Organics test method. Such regulation can reduce the risk of a flash sewer fire, resulting damage and potential injury. The updated 2003 VSO process developed by Severn Trent Laboratories produced data that was equivalent to the 1990 VSO process developed and used by the ...

  • Solvent choices for infrared testing of oil and grease in water

    Water is a very strong absorber in the mi d infrared (I R) regio n where o il is measured. We see the effect of infrared absorbance when a cold bucket of water left in the sun is quite warm by afternoon due to the absorption of infrared energy as heat. When measuring part per million (ppm) oil levels with mid IR, the water absorbs so much of the infrared energy that the signal becomes saturated ...
