  • What is a Breathing or Respiratory Zone?

    In the past, vehicle exhaust gas detectors have been installed on or near the ceiling. In contrary, Critical Environment Technologies Canada Inc. (CETCI) has always recommended that they be installed in the breathing zone. Recently, Quebec’s regulation has reinforced CETCI’s recommendations. It states that “dusts, gases, fumes, vapours and mists found in the workplace ...

  • Compressed breathing air safety - how important is it?

    At first glance the physiological demands of the firefighter, the scuba diver and the hospital patient have little in common. One is trained to deal with fire and rescue, one swims underwater and one is concerned with either regaining or improving their health. Yet all three depend to some extent on a safe source of compressed breathing air, which is where our gas detection systems come in. ...

  • Carbon Tetrachloride and Prop 65, What You Need to Know

    In 1986, California voters approved an initiative to address increasing concerns about exposure to toxic chemicals. That initiative, the Safe Drinking Water and Toxic Enforcement Act of 1986, is better known by its original name of Proposition 65.  Proposition 65 requires businesses to notify Californians about significant amounts of chemicals in the products they purchase, in their homes or ...

  • Firmness evaluation of melon using its vibration characteristic and finite element analysis

    Analysis of the vibration responses of a fruit has been suggested as a non-destructive measure of its elastic properties (firmness). In this study, 'Huang gua' melons were excited using three types of balls (wooden, steel and rubber) and the vibration was detected by an accelerometer. The modulus of elasticity of the inner, middle and outer portions of melon flesh were determined using flat plate ...

  • Typical Sensor Location Considerations

    The sensor mounting location within a space may be dependent on many variables. There are no specific formulas since each application will have it’s own determining factors and priorities. These include, but are not limited to: source of gas: Is the source a combustion exhaust from a vehicle or furnace or a vapour from a tank spill, pipe leak, or faulty valve? density of ...

  • Elimination half‐life as a metric for the bioaccumulation potential of chemicals in aquatic and terrestrial food chains

    The assessment of chemicals as bioaccumulative in the regulatory process makes use of the bioconcentration factor as a metric. However, this metric does not account for the dietary uptake route and therefore cannot be applied to terrestrial food chains. In recent years, the biomagnification factor (BMF) and the trophic magnification factor (TMF) have been suggested as standard metrics for ...

  • New and dangerous mold

    Cryptococcus gattii was considered to be a mold found only in semi tropical and topical climates until it was found recently in the Pacific Northwest. It seems to have adapted to the cool, wet environment on Vancouver Island, Canada and spread from there to western Canada, Washington (state) and Oregon. It may have already spread to Idaho and California. Normally, Cryptococcus molds are capable ...

  • The relationship between asthma and ambient air pollutants among primary school students in Durban, South Africa

    We examined the prevalence of asthma among students in Grades 3 and 6 at a primary school located in the highly industrialised South Durban Industrial Basin. After baseline interviews and methacholine challenge testing (MCT), students completed bihourly symptom logs during an 18-day study period. Continuous measurements of ambient contaminants at the school included sulphur dioxide (SO2), oxides ...

  • Case Study: Singapore Airlines

    Ellis was contacted after a client had several complaints from employees related to air quality. Ellis conducted exposure monitoring for CO2 and CO, and also took measurements of temperature and relative humidity. Results of the study showed CO2 and CO to be well under the PEL (Permissible Exposure Level) for those two gases. However, elevated temperatures occurring later in the day appears to ...

  • Refractories, plastics, insulation or textiles containing chromium compounds - Case study

    Purpose The original version of this Plant Service Bulletin (PSB-43) was issued in April of 1990 to alert owners and operators of boilers and steam generators that certain materials containing chromium may, under certain operating conditions, produce hexavalent chromium (Cr + 6), a carcinogen. It also suggested remedial action and substitute materials. The initial issue of PSB-43 ...
