x UK Focus on Personal Safety at Work Protect your workforce from chlorine dioxide exposure
Chlorine dioxide or CLO2 is commonly used in the disinfection of water across a variety of processes and industries. It is a powerful oxidising agent that dissolves on contact with cold water which is why it is so widely used throughout water treatment plants, food and beverage production and paper processing.
However, Chlorine Dioxide is a highly toxic and fl ammable gas that can cause serious harm and even death if it is inhaled. It is estimated that up to 1400 tonnes of aqueous chlorine dioxide are used per year in the United Kingdom which is why occupational exposure incidents are high and gas detection equipment is essential for the health, safety and welfare of the workforce.
Chlorine Dioxide is widely used in water treatment plants to control a wide range of harmful bacteria and microbes. Compared to other disinfection agents, CLO2 can disinfect and sanitise in seconds and remains effective even when the pH level of water rises. It is also extremely effective when it comes to controlling legionella bacteria and preventing Legionnaires Disease and is widely used in hot and cold domestic water systems, cooling water systems, swimming pools, hot tubs and spas.
Chlorine dioxide is a bi-product from the process of using chlorine to prepare poultry, fruit and vegetables prior to packaging. As well as providing exceptional microbiological control in packaging operations, Chlorine is one of the most powerful, yet environmentally safe biocides in common use in the food industry, as it is an extremely effective biocide at levels that are considered safe for human consumption and does not produce carcinogenic by-products.
Chlorine dioxide was fi rst used in Sweden in 1946 for the purposes of pulp bleaching. Since then it has become the most widely used oxidizing agent in paper processing and production due to its solubility in water and its ability to attack phenolic groups of lignin without degrading cellulose fi bre which produces an increased yield and higher strength bleached pulp.
But although there are many production process benefi ts to using chlorine dioxide, it can be harmful if your workforce is either exposed to it over long periods of time or if a leak should occur as it reacts quickly with water and moist body tissues which can cause damage to the nose throat and lungs and in high enough doses, prove fatal. The HSE has set WELs for both long term and short term exposure to Chlorine Dioxide of 0.1ppm and 0.3ppm respectively. The only way to measure these exposure limits is through the use of both fi xed and portable gas detection equipment depending on the processes carried out and positioning of plant equipment.
GfG has a variety of both fi xed and portable gas detection equipment that can protect workers from CLO2 exposure and are most effective when used together. The GMA36 pro is one of their most popular units for measuring CLO2 exposure as it is a combined transmitter and controller. It includes a display, sensor, both audible and visual alarms and is mains powered with a battery backup. GfG’s EC-28 series of highly confi gurable toxic gas transmitters can be equipped with exactly the right confi guration of sensors, displays, relays and local alarms needed for your specifi c application. The units can be installed as a customised installation with controllers located in a ‘safe’ area that will prevent entry into affected areas in the event of a leak. Workers that are on the frontline of production will benefi t from portable gas detection equipment located within their breathing zone to ensure that occupational exposure limits are not being exceeded. A simple one gas portable measurement device such as the Micro IV and Micro V provide a cost-effective solution to risk management and employee welfare. As part of their fl exible approach to customer service, GfG offers a free gap analysis of your business gas detection needs. There is no obligation to take up this service and it can be used as part of your health and safety and risk management process.

offers fi ve day lead time as standard In a move to safeguard the quality of measurements and eliminate the costs associated with unreliable monitoring equipment, AcSoft is offering traceable calibration of a wide range of noise and vibration instrumentation with a fi ve-day lead time as standard.
AcSoft’s state-of-the-art acoustic calibration laboratory is capable of calibrating a variety of noise and vibration equipment from its subsidiaries, Svantek UK and GRAS UK, as well as instruments from other manufacturers. The laboratory calibrates sound level meters, microphones, preamplifi ers, calibrators and pistonphones, accelerometers (frequency response and sensitivity), analysers and dosimeters. The company uses the goCA calibration systems from GRAS for calibration of microphones, sound level calibrators and pistonphones.

For calibration of sound and vibration meters, AcSoft uses a bespoke calibration system from Svantek Poland. A full factory calibration is performed on Svantek products ensuring all new instruments have a fresh calibration certifi cate every time. A bespoke shaker system from Data Physics is used for sensitivity calibration of accelerometers over a range of frequencies. A Dytran 3123AK reference accelerometer set is used.
AcSoft’s equipment is located in an air conditioned, purpose-built laboratory and is calibrated to nationally traceable standards. Return shipping is free of charge – within the UK – and the company can also arrange collection of kit, if required.

New dosimeter take the Edge off noise pollution
Quest noise dosimeters, from TSI, are powerful and intuitive instruments designed for identifying hearing loss threats in all environments. After acquiring the Quest brand of products from 3M in 2018, TSI recently launched the Quest Edge 4+ noise dosimeter. The Edge 4+ lets safety professionals monitor a worker’s noise exposure in real-time with the Edge dB mobile app. The ability for a safety professional to program, monitor, and capture survey data at a safe distance allows the worker to perform their tasks without interruption. The Edge 4+ noise dosimeter with Bluetooth option syncs to the Edge dB mobile app for total management of the dosimeter.
“After demonstrating the benefi ts of the new Quest Edge 4+ at AIHce and ASSE industry conferences, we have received tremendous positive feedback regarding the ability to monitor noise levels without disrupting workers,” said Troy Tillman, Business Director for Test & Measurement Instrumentation at TSI. “This innovative offering adds to our comprehensive portfolio of solutions for Occupational Health and Safety Professionals.”
The Edge product line of noise dosimeters is shoulder-mounted, providing ergonomic, convenient measurements. Units are compact, with large displays and intuitive interfaces to provide crucial information at a glance and in real-time.
