  • Detect Hydrogen Gas and Flames

    Under day-to-day conditions, people cannot see, smell, or taste the presence of hydrogen gas. Hydrogen, however, is very flammable and requires only a small amount of energy to ignite. In fact, if leaking from a pipe at a high enough pressure, hydrogen gas can self ignite without the aid of an external energy source. Working together, ...

  • Detecting Hydrogen Gas and Fires: Seeing the Unseen

    Hydrogen usage is growing. The general public sees and reads about hydrogen as an alternative fuel for cars. However, the big use for hydrogen is found in hydrocarbon processing and other important manufacturing processes. Hydrogen is the first element on the periodic table and is an essential element in the manufacturing of many of our everyday products. We must have respect for its explosive ...

  • Developing Technologies to Detect Hydrogen Sulfide (H2S) Gas

    Abstract Hydrogen sulfi de (H2S) gas can cause nausea, headaches, unconsciousness, and death. Industries struggle to detect this deadly substance before it harms workers or communities. Safety system manufacturers have developed detectors that sense the H2S quickly and accurately. This paper illustrates, in general terms, considerations in effective placement of H2S detectors: ...

  • Danger and Detection of Hydrogen Sulphide Gas in Oil and Gas Exploration and Production

    A rig worker smells rotten eggs near the well head, rubs his itchy eyes as he investigates the frosty pipe connections. After a few moments, he believes all is fine as he no longer smells the tell-tale hydrogen sulphide odour. In this scenario, we can only hope the worker recognises the danger and quickly leaves the site. Oil fields, especially mature ones, can produce hydrogen sulphide gas ...

  • Chlorine Safety and Prevention: How to Protect Yourself from Chlorine Leaks

    While chlorine gas is widely used in swimming pools, water treatment facilities, cleaning products, pharmaceutical products, and in many other industries, the gas is highly toxic when handled improperly. Training your workers on how to safely use chlorine is one part of health and safety best practices; monitoring your workplace for chlorine leaks is another. Learn about the hidden dangers in ...

  • Fixed Versus Portable Gas Detection – Which Is Better?

    Did you know that workers are needlessly injured every year as a result of leaking toxic or combustible substances? Such incidents are known to involve a wide range of hazardous gases (including ammonia, carbon monoxide, chlorine, hydrogen sulfide, hydrocarbon vapors and so on). The sad reality is that most of these accidents are avoidable if only the workplace is adequately monitored. This leads ...

  • Detecting Gases: What You Can`t Smell Can Hurt You

    Walking through a drill-site area, a worker smells rotten eggs and stops tor a minute or two to assess where a gas leak might exist. Rubbing his itchv eves as he investigates further, he notices that he no longer smells the tell¬tale hydrogen sulphide odour. He does not realize that the gas has deadened his olfactory senses and unless he leaves the area within seconds, he could lose ...

  • Is your Plant as tight as you think? Leak Detector for extremely toxic Gases, a Field Test Report

    Leak detection of commodity gases in chemical plants is a day-to-day practice. The sensor technology available for this application is field proven and reliable. No question about it, existing sensors will do the job. However, in plants manufacturing or handling extremely toxic substances, the picture is different. For example, take phosgene. The existing sensor technology for leak detection ...

  • Wastewater force main management – internal corrosion survey using inline methods

    In our first post about Wastewater Force Main Management, we looked at how preliminary analysis helps operators develop a plan for managing their system. After completing this process, operators can begin putting the plan into action with preliminary surveys on specific force mains. For those at WEFTEC, you can visit Pure ...

  • Controoling chlorine costs

    The most widespread disinfectant used in the treatment of drinking water is chlorine, which can be applied in a variety of ways. History has taught us that, in bacteriological terms, chlorinating water is a proven way of disinfecting drinking water. After all, more than 75 years have passed since chlorine was used to disinfect drinking water for the first time. Many years of experience have shown ...


  • PureAire Universal Gas Detector Offers Protection Against Toxic Levels of Ammonia

    In March of 2016, an ammonia gas leak at a seafood processing plant in Boston left one worker dead. The fumes at the plant were so powerful that firefighters could not promptly enter the scene to mitigate the gas leak and try to save the staff member until much later. Reports show that 5,300 pounds of ammonia gas leaked out of the plant. If you work with ammonia at your facility, learn ...

  • Safety Systems Depend on Reliable Field Sensors (Emphasis on Fire and Gas Detectors)

    Abstract Because not all hazards are the same, identifying and quantifying the hazard is the starting point in choosing sensing technology. Not all detectors are the same, and they should be selected according to their ability to detect the hazard. This paper gives a broad summary of technologies that provide users reliable responses to hazardous conditions, that minimise false ...

  • 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 ...

  • Odor Eliminators For Roof Top Vents Often Called Stink-Pipes

    Every state, city, and village either has odor ordinances or treats obnoxious odors perceptible beyond property lines as public disturbances/nuisance. All plumbing vent stacks produce odors unless they fitted with a filter. OSHA warns that levels of 300-ppm (H2S) cause the olfactory nerve to lose sensitivity. At first a “rotten egg” odor is detected but on the second or third breath the odor ...
