worker exposure Applications

  • Radiation Worker Training

    Safe Training Systems (STS) are specialists in the provision of high quality, highly realistic simulated radiation monitors. STS have sold instruments for training to over 12 different countries across the world the majority of which have been used for Nuclear Worker training. The simulation system uses completely safe methods to recreate radiation fields and contaminated surfaces, this means that novice users can be taught basic principles without any exposure. There are of course also benefits to the trainer who again does not accumulate any dose and can therefore carry out more sessions. Instruments for workers vary widely from the Thermo Electra, RO2/20 and FH40G through to Ludlum model 3s and Automess 6150AD. With a wide range of instruments and sources there is always a solution to fit both budget and purpose - please contact for more information.

    Measurement solution for hospital workplace exposure monitoring

    In taking a responsible stance on the exposure of workers to any potentially hazardous gases, there is a need for workplaces using anaesthetic gases, such as hospital operating rooms or research laboratories, to control the level of waste anaesthetic gas in the ambient air.

    Measurement of methyl bromide in ambient air for monitoring workplace exposure limits in fumigation facilities

    The Series 8900 Methyl Bromide Monitoring System provides an automated, direct measurement of Methyl Bromide in ambient air. This instrument can meet and exceed the requirements for ambient methyl bromide monitoring. It is utilized in fumigation facilities and industrial plants to detect potential worker exposure to methyl bromide, resulting from mechanical failure, human error or product off gassing. Multipoint sampling options allow the analyzer to monitor multiple sample locations for greater coverage.

    Gas monitoring instruments and systems for flavoring agents

    Manufacturing of powdered and liquid flavorings and fragrances involves production phases where flavoring chemicals may be released into the ambient air breathed by workers. Exposure control by gas analyzers in the production rooms and laboratories is necessary to ensure that the Time-Weighted Average (TWA) concentrations do not exceed the maximum Permissible Emission Limit (PEL) values.

    Gas monitoring instruments and systems for print factories

    Typical modern printing processes utilize solvent-based dyes. The evaporation of the dye solvents into the ambient air during the printing process may expose the workers to various chemicals. Depending on the type of solvents in case, the solvents have different long term exposure limits, which should be obeyed. Component specific measurements are necessary to protect the workers from exposure while avoiding unnecessary interruptions to the printing process from false alarms.

    Air sampling & monitoring systems for occupational health & safety industry

    HI-Q considers the responsibility for worker health and safety to be of paramount importance. This is a responsibility that requires good documentation of facts. Many studies are conducted to evaluate workplace health and safety conditions as they relate to workers exposure to radiation, chemicals, and biological hazards during the normal work day. HI-Qs wide line of air sampling equipment, systems and accessories are used in the monitoring then documentation of these workplaces.

    Tunnel Construction and Underground Mining

    Dust can pose a particular hazard for people working in enclosed spaces such as in tunnel construction and deep mining. As the workers inhale, dust gets into their airways and can cause health problems. Poor visibility brings added exposure to risk. A reduction in the amount of dust generated also lengthens the service life of the machines. Therefore efficient dust control is particularly important in this industry.

    Analysis of Isocyanates Using the ASSETâ„¢ EZ4-NCO Dry Sampler

    Isocyanates are used as a raw material to produce a number of products . Personal exposure can occur while the products made with isocyanates are being applied, or when the materials are removed by grinding or thermal degradation. Workers who are exposed to these compounds are at risk for respiratory disorders and asthma. The highly reactive nature of the isocyanate compounds and the low occupational exposure limits put high demands on both sampling and analytical techniques for monitoring of isocyanates in air. We investigated the performance of the LC-MS and LC-MS-MS methods in the analysis of isocyanates using the new ASSETâ„¢ EZ4-NCO Dry Sampler. We found that the analytical method can successfully reach the quantitation limit for most isocyanates of 5 ng/mL in the final sample when LC-MS-MS analysis was used and the quantitation limit of 10 ng/mL when LC-MS analysis was used. All 11 compounds were well-resolved chromatographically using a 15 cm Ascentis Express C18 column.

  • Gas detection for the winery and brewery Industry

    Once an archetypal example of manual production, the winery and brewery industries now incorporate sophisticated processes to ensure high quality levels and efficient output. In some cases traditional approaches have simply been scaled up or put under more stringent monitoring, whilst in others innovations such as nitrogen-pressurised canning have been introduced. However, whichever approach has been followed there is also a growing realisation of the gas hazards that are associated with both new and old processes, and the need to protect workers from toxic gas exposure and asphyxiation risks.

  • Gas detection for the steel industry

    Regarded by many as providing the backbone to modern society, the steel industry is one which continues to evolve. Whether it is geographic shifts in demand or production, or challenges brought by energy or raw material costs, companies continue to develop their processes and facilities to meet them. Alongside these changes companies have also realised the requirement to minimise downtime due to unplanned maintenance and protect workers from exposure to toxic or flammable gas hazards.

  • HCl Monitoring in Air

    Hydrogen chloride (HCl) is a colorless, sometimes slightly yellow, gas. It is an undesired environmental component that may be damaging to workers and the surroundings. Exposure limits have thus been established by industries to make sure that the workers operate in a safe environment. HCl monitoring is especially required for incinerators, coal-fired power plants, aluminum recycling and cement plants. Unisearch offers a reliable and easy-to-use HCl analyzer – the TDLAS-based LasIR system. Studies have shown that TDLAS equipment provides data that is more accurate than conventional gas monitoring equipment. When calibrated for HCl monitoring, TDLAS is able to detect this gas among other gases present in the area and provide continuous updates with regards to the changes in its concentration.

  • Soldering Fume Extraction

    Soldering fumes are Unbreathable. Soldering enables the joining of metal parts by melting a filler metal to attach wires and other metallic components. The fumes generated from melting solder especially solder containing Lead or Tin present are dangerous and require local ventilation to remove harmful smoke from the work area. Soldering application need to be properly ventilated to prevent toxic fumes from reaching the worker`s breathing zone. There are a number of different industries such as the electronics assembly industry and electronics repair comapnies who must deal with the hazards of solder smoke. Fumes created by automated PCB soldering including wave soldering machines, handheld soldering irons, torch brazing and furnance brazing are often ignored because of the small volume of smoke generated. However, these applications still require careful consideration as dangerous fumes can impair employee’s respiratory tracts depending on the filler metals used. Because manual soldering applications require working with tiny components, workers end up positioning their heads right above toxic rosin or lead solder fumes with a direct exposure into their throat, nasal passages and lungs, and as a result, they can experience respiratory complications. Rosin irritation can cause various side effects and the inhalation of lead fumes is carcinogenic. As lead oxide smoke collects in your lungs, it can be transferred into your bloodstream. Diversitech recommends installing soldering fume extraction equipment to prevent the inhalation of dangerous fumes. These ventilation units will not only protect each person working at a soldering station when installed and positioned correctly, but they will also prevent fumes from contaminating other worker’s lungs.?
