  • Monitoring personal noise exposure in West end theatres with the doseBadge5 - Case study

    When the audience sits in the stalls of a West End theatre they have very little idea of the technology that goes into giving them the ultimate live show experience. Some shows enjoy runs that last for years, others aren’t so lucky, but each night there is a team of front of house staff and stagehands that bring the magic to life. The noise risks of working in a live music venue are ...

  • Personal exposure to particulate air pollution in transport microenvironments

    Personal measurements of exposure to particulate air pollution (PM10, PM2.5, PM1) were simultaneously madeduring walking and in-car journeys on two suburban routes in Northampton, UK, during the winter of 1999/2000.Comparisons were made between concentrations found in each transport mode by particle fraction, between differentparticle fractions by transport mode, and between transport ...

  • Exposure to environmental tobacco smoke at work, at home, and during leisure time: personal exposure measurements by diffusive sampling of airborne 3-Ethenylpyridine

    Environmental tobacco smoke (ETS) is associated with an increased risk of several diseases. In 2002, the ETS exposure level was studied in a Finnish cross-sectional population sample with a sub-sample of currently working nonsmokers. In all, 123 nonsmokers (25-64 years) reporting at least 1 h of daily exposure to ETS participated in personal exposure measurements. Two 3 M organic vapor monitors, ...

  • Outdoor/Indoor/Personal Ozone Exposures of Children in Nashville, Tennessee

    An ozone (O3) exposure study was conducted in Nashville, TN, using passive O3 samplers to measure six weekly outdoor, indoor, and personal O3 exposure estimates for a group of 10- to 12-yr-old elementary school children. Thirty-six children from two Nashville area communities (Inglewood and Hendersonville) participated in the O3 sampling program, and 99 children provided additional timeactivity ...

  • SDS Authoring Software

    When creating an official SDS that will be distributed via SDS software, it is critical that those who are responsible for SDS services follow the standardized document format. This format ensures that all information deemed essential to understanding a chemical and the potential hazard it presents is provided on one easily referenced sheet. SDSs must be generated to include sixteen specific ...

  • Tracking pollution at a personal level

    Two big stories from 2014 were the amount of air pollution in cities, especially in China, and the rise of “wearables” and other personal technologies people use to track things about themselves, often having to do with health and fitness measurements, such as steps taken, hours slept, heart rate and more. Now, the ...

  • Personal Noise Solutions for Miners

    Throughout the working day, miners are continually exposed to varying levels of noise which can result in hearing loss. For safety reasons it is important to monitor employees’ noise exposure and Cirrus Research has created such a device in the form of the CR: 110A doseBadge. The Cirrus Research doseBadge is the original wireless personal noise dosemeter. It is the ideal tool to carry out ...

  • Now It’s Personal

    Prosecutors are targeting executives in environmental liability cases. LET’S ASSUME THAT YOUR WASTE COMPANY- by virtue of its operations — is a risky business. Potential environmental liability lurks everywhere. Not too many years ago, state and federal regulators were content to target corporations for environmental criminal investigations. Today, however, their focus is on ...


  • Low-dose monitoring for occupational exposure and the influence of measurement accuracy

    This paper presents the evolution of individual radiation doses received by occupationally exposed workers. The individual doses accumulated over the period 2000-2007 correlated to nuclear laboratory and radiation source (gamma, X-rays) types are in the low radiation range. Dose equivalent Hp(10) was measured by a film dosimeter system; the influence of the measurement accuracy on the results was ...

  • What is the REACH of your exposure?

    Margarethe Jaroszewski of 3E Company looks at the extra burden REACH Exposure Scenarios will bring The REACH Regulation went into effect on 1 June 2007, simplifying but also complicating the compliance work for companies manufacturing or importing chemicals in Europe. As a result, all companies manufacturing, importing, distributing or using chemical substances on their own, in mixtures ...

  • A numerical analysis of the aspiration efficiency of a personal sampler

    The impact on sampling efficiency of increasing the flow rate of a low flow personal sampler has been examined. Increases in flow rates were required to obtain sufficient particle mass over the duration of a typical rush hour commute (3.5?16.7 litres/min). Computational Fluid Dynamics (CFD) modelling has been used to assess the implications of this higher flow on the aspiration efficiency of the ...

  • Noise Measurement

    Definitions Threshold and criterion levels The threshold level is the A-weighted sound level at which a personal noise dosimeter begins to integrate noise into a measured exposure. For example, if the threshold level on a sound level meter is set at 80 decibels (dB), it will capture and integrate into the computation of dose all noise in the employee's hearing zone that equals or exceeds 80 dB. ...


  • In-Vehicle exposures to particulate matter and black carbon

    ABSTRACTIn-vehicle exposures to particulate matter (PM) and black carbon (BC) can be a significant part of personal totalexposure. The purpose of this study was to identify determinants of the in-vehicle pollutant level. This study measured in-vehicle exposure to PM number concentrations using an aerosol spectrometer and BC concentration by an aethalometer. The measurement was repeated 3 ...

  • Meeting the challenges of employee noise exposure in the oil and gas industry

    Noise exposure legislation, designed to protect the hearing of employees and prevent noise nuisance, is becoming tougher and more widespread. Cirrus Research plc provides a range of noise measurement instruments which have been designed to provide noise measurement solutions. In particular, the doseBadge Personal Noise Dosemeter is widely used in the Petrochemical and Mining industries where the ...

  • Exposure to dust, endotoxin and airborne microorganisms in wastewater sludge thermal drying units

    The objective of this study was to assess workers' exposure to bioaerosols in sludge drying units. Simultaneous collection of inhalable dust and airborne biological agents was carried out using rotating cup samplers (CIP 10, Arelco). Sixteen stationary and 30 personal measurements were performed in three drying plants, during summer and winter. Microbial content of air was characterized by high ...

  • Symptoms vs. Systems: are we taking safety too personally?

    In the US our fatality rate has been flat (total fatalities are actually up a bit the last couple of years) for a decade despite our incident rate’s steady decline to an all-time low.  In addition recent disasters such as the chemical exposure fatalities at La Port Texas, the Texas City Refinery explosion and the Deepwater Horizon have demonstrated ...

  • Dispersion models and air quality data for population exposure assessment to air pollution

    Evaluating the extent of exposure to chemicals in absence of continuous measurements of their concentration in air and direct measures of personal exposure is crucial for epidemiological studies. Dispersion models can be a useful tool for reproducing spatio-temporal distribution of contaminants emitted by a specific source. However, they cannot easily be applied to short-term epidemiological ...
