  • A Comparison of Point Sensors and Open Path Monitors For Toxic Gas (esp. HF) Monitoring

    Point Sensors Ion Mobility Spectroscope (IMS) – a gas sample is ionized by a radioactive source (Ni63). Differences in ion drift under the influence of an applied electric field produce a spectrum that is dependent on the mass, charge, and shape of the component ions. The detector signal and strength is tuned to the drift time of the ion of interest (in this case HF) and signal strength is ...

  • Monitoring Multiple Gas Hazards in Ice Arenas

    The equipment used in an arena such as an ice re-surfacer, ice edger, floor sweepers, lift trucks and other special equipment are more often powered by fuel than electricity. The exhaust produced by the gas, propane or diesel fuel powered machines emits, into the air, carbon monoxide (CO), nitrogen dioxide (NO2) and particulates. Ammonia (NH3) is commonly used in the ice chiller mechanical room ...

  • Electrochemical Sensors for Specific Gas PPM Monitoring

    Echem sensors are able to read a specific gas even when it is mixed in a background of other gases. Echem sensors are typically used to read very low PPM concentrations of toxic gases. The Echem sensor consists of a small cell holding an electrolytic solution. This solution needs a specific gas in order to produce an electrical signal. When the specific gas passes through a permeable membrane and ...

  • Gas Monitoring for Ventilation Control and Energy Management

    The growing demand for underground and enclosed parking and maintenance garages (resulting from limitations on land availability) has increased the awareness and need for proper ventilation and control systems. In addition, increased health and safety programs have only added to the concerns of toxic and combustible gases in confined or enclosed spaces. Historically, ventilation and make-up air ...

  • PureAire Universal Gas Monitor Receives UL Listing

    PureAire is pleased to announce that its PureAire Universal Gas Monitor received the UL/CUL listing for models 99030 and 99031. PureAire’s Universalmonitors comply with national and international safety standards, including UL 61010-1, CSA C22.2 NO. 61010-1-12-CAN/CSA, and IEC/EN 31010-1.  Designed to protect against toxic gases including ammonia, bromine, chlorine, hydrogen ...

  • 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 ...

  • Monitoring And Analysis of Landfill Gases

    CoGDEM is the trade association representing manufacturers and service providers who are active in the field of gas detection instrumentation and environmental monitoring apparatus. Crowcon Detection Instruments Ltd was one of the founding members of CoGDEM, and in this article their Product Manager of Fixed Systems, Andy Avenell, gives an update on Landfill Gas. Landfill is by far the most ...

  • The Toxic Effects of Hydrogen Sulfide (H2S) Gas from Sewers on Health & Infrastructure - Case study

    How is Hydrogen Sulfide Created? Hydrogen sulfide emitted from sewers and septic tanks can cause serious health issues. Hydrogen sulfide gas is created and released into the air when waste water remains stagnant for a long period of time, and becomes depleted of dissolved oxygen. Although sewer workers are most likely to be affected by hydrogen sulfide overexposure, people living or ...

  • Understanding the Benefits of Fixed Gas Detection

    "Fixed gas detection is an essential method of ensuring maximum protection for personnel and plant. There are a variety of technologies available for a multitude of applications. Understanding fixed gas detection is the first step in providing safety." What is fixed gas detection? Fixed gas detection is installed with the aim of providing continuous, area and personnel protection. ...

  • Gas Safety in Confined Spaces

    Introduction An offshore worker ensures a vessel is safe to enter; a plant manager enters a small plant room; a contractor inspects the lining of a sewage pipe.  All these personnel face common dangers, despite working in widely different industries.  Gas-related injury poses a serious threat in any confined space where the free movement of air is limited. A confined space ...

  • Installation of the fixed gas detection

    OC-F08 fixed gas monitor with the original imported sensor used to detect the Oxygen gas, combustible gas, toxic gas, CO2, etc. With the different working principle, Electrochemical sensor for O2 and toxic gas, Catalytic combustion sensor for combustible gas, PID sensor for the VOC, Infrared sensor for the CO2 ...

    An engineer repairs buried cables; a plant manager enters a small plant room; a contractor inspects the lining of a sewage pipe.  All these personnel face a common danger, despite working in widely different industries.  Gas-related injury poses a serious threat in any confined space where the free movement of air is limited.  ...

  • Pollutant monitoring in sludge treatment wetlands

    Phragmites australis for sludge dewatering and stabilization processes have been widely proved. The presence of reeds, indeed, efficiently allows solids dewatering and organic matter stabilization in order to obtain a stabilised product that can be suitable for land application, even if its environmental impact has to be considered. The actual revision of the European Union's Working Document on ...

  • Gas detector communication technology for offshore oil and gas platforms

    In few applications is safety as important as on offshore oil and gas platforms. Explosive hazards from hydrocarbon gases and vapours are an ever-present risk, whilst toxic hydrogen sulphide gas and depleted oxygen environments can pose significant risks to personnel. Gas detectors are therefore essential to provide dependable early warning of gas hazards. Gas detectors are permanently installed ...

  • Gas Safety in Confined Spaces

    Introduction A confined space is any space large enough for someone to enter and perform assigned work, which has limited means of entry or exit, and which is not designed for continuous worker occupancy. This covers just about every industry, including utilities, construction, hydrocarbon exploration and processing, petrochemicals, marine, agriculture, food processing and brewing, as ...

  • PureAire Combines Oxygen and CO2 Sensors to provide a Dual Gas Monitor to the Marketplace

    As a recognized leader in O2 safety monitoring, PureAire recently explored the need for an O2 monitor where carbon dioxide is used. There are four key cryogenic gases; nitrogen, helium, argon, and carbon dioxide (CO2), which can create an oxygen deficient atmosphere. Material Safety Data Sheets (MSDS) covering cryogenic gases cite that a cryogenic leak can create an unsafe ...
