  • Asbestos Awareness: Preventing a Hazardous Workplace

    Many on-the-job hazards are obvious... leaking machinery... dangerous chemicals... slippery floors. However, other hazards aren't so obvious. There may be no visible signals that they are present at all. That's why Asbestos is often known as 'the silent killer.' While you often can't see, taste or smell it..., prolonged periods of exposure to Asbestos can cause lung disease, cancer... even death. ...


  • CO2 Gas Hazards in the Brewing Industry

    The hazards associated with CO2 in the brewing industry are well known, yet people still die needlessly every year in tragic and completely avoidable accidents in breweries. Just last year in Germany, which has a good safety record, two workers died in separate incidents at the same brewery. In the first incident, the owner was found dead with his head and torso in a beer mixing tank. It is ...

  • A Methodological Approach to Land Use-Based Flood Damage Assessment in Urban Areas: Prague Case Study

    In recent years, extreme river flooding has occurred in several regions of Europe. This phenomenon, which includes the dramatic flood events in central Europe in summer 2002, is mainly due to an increase in the vulnerability of regions to flooding. As a result, there is currently great public interest in this issue, and it is necessary to intensify research activities in order to understand ...


  • The impact of urban areas on the deposition of air toxics to adjacent surface waters: A mass budget of PCBs in Lake Michigan in 1994

    The impact of urban air toxics on the proximate water bodies was investigated as part of the AEOLOS Project (Atmospheric Exchange Over Lakes and Oceans). The hypothesis of this project was that emissions of hazardous air pollutants into the coastal urban atmosphere increased atmospheric depositional fluxes to proximate Great Waters. Areas of major field and modeling campaigns were located in ...

  • The determination of major and minor elements in air filters and urine for hazard assessment, using a new CCD DUAL-VIEWED ICP optical emission spectrometer

    This article describes the application of a new type of CCD-based, dualviewed ICP optical emission spectrometer for the analyses of industrial hygiene types of samples. Several trace elements in air filter media are determined by ICP-OES. Urinary electrolytes and trace elements are determined in a single dilution automatically in both the axial and radial plasma viewing orientations. Results of ...

  • Community Response to Broadcast Media for Cyclone Warning and Disaster Mitigation: A Perception Study of Coastal People with Special Reference to Meghna Estuary in Bangladesh

    Abstract: Coastal belt and offshore islands of Bangladesh are vulnerable to catastrophic cyclone hazard. The broadcast media - radio and television - play a very important role to disseminate cyclone warning news bulletins to the people living in those areas, and also act to bridge the gap between the decision makers and the public. Information collected from 400 respondents at nine different ...


  • 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 ...

  • What is Intrinsic safety and ATEX?

    What is intrinsic safety? Intrinsic safety (IS) is a low energy signalling technique that ensures the safe operation of electrical equipment in hazardous areas by limiting the energy – both electrical and thermal – available for ignition. ...

  • 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 ...

  • 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 ...

  • Heavy Lifting with Cranes

    Extend extra care not carelessness For any kind of lifting due care and consideration of risks should never be disregarded; as loads increase so to do the risks and level of care required to manage safely with crane operation being one of the most precarious examples. Heavy lifting operations are considered to be complex for a ...

  • Hydrogen-cooled electric generators case study

    Application Moisture contamination is measured in the hydrogen gas used to cool large stationary electric generators. Problem Hydrogen is used to cool the bearings and other rotating parts of large stationary electric generators. Hydrogen is the best choice for a cooling gas because of its unique combination of high thermal conductivity and low viscosity. In ...

  • Ensuring personnel safety in a confined space

    “There are no second chances with a confined space entry. It has to be right first time.“ Identifying a confined space… The HSE Confined Space Regulations 1997 define a confined space as: “A space of an enclosed nature where there is a risk of death or serious injury from hazardous substances or dangerous conditions” Some confined ...

  • 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 ...

  • Upgrading from Pellistor Gas Sensors to Infrared Technology

    In this article Andy Avenell, Crowcon’s Fixed Systems Product Manager, considers the shift towards infrared (IR) gas sensor technology in the oil and gas industry. Abstract Flammable gases and vapours can present considerable dangers in many industrial applications, none more so than the processes involved in extracting, transporting and processing oil and gas. Fast and reliable ...

  • 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 ...

  • Gas safety in confined spaces

    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.  ...
