4 Gas Detection The fi rst BS8484:2022 certifi ed gas detector
G7c personal wearable by Blackline Safety is the world’s fi rst connected gas detector and lone worker safety monitor certifi ed to the newly-upgraded BS 8484:2022, the standard that underpins the UK’s lone worker safety leadership. Lone workers are those who work by themselves without close or direct supervision. Employers have a legal obligation to manage any health and safety risks before their employees can work alone. In addition to the almost 700,000 incidents of violence at work in the UK in 2019/20, lone workers face the risks of slips, trips, falls, health events, extreme weather, vehicular accidents and a number of other potentially harmful events. There are also concerns related to stress and mental health, medical suitability to work alone, and the workplace itself, for example, if working in an isolated or remote area. Ensuring the safety of these at-risk workers has always been a top priority for Blackline Safety.
“Considering employee safety, wellbeing and security at a strategic level leads to a culture of safety at work at the operational level,” said Natalie Hays, QHSE & Compliance Manager, at Blackline Safety Europe Ltd, a fully-owned subsidiary of Blackline Safety Corp. “BSI (British Standards Institution) states that ‘lone worker protection might be a consideration for both safety and security strategies. It contributes to the organisation’s governance, management of risk and compliance with both company policies and legal obligations.’” Lone Worker monitors enable organizations to maximise workers’ safety with incident detection and emergency response services to ensure most vulnerable team members are always accounted for and return home safely to their families at the end of each working day.
Due to stringent Health and Safety laws, outlining the responsibilities of employers in signifi cant detail, the UK is considered one of the safest places in the world to work. Strict regulations and industry best practices help ensure employers offer an unparalleled duty of care to their workers. BS 8484:2022 defi nes the industry-leading code of practice for lone worker equipment and monitoring services in the UK. “The UK’s thorough safety regulations help ensure we consistently achieve success in keeping people safe while at work,” Hays said. “The BS 8484:2022 standard underpins the UK’s safety leadership by providing lone worker product and service providers with a code of practice that allows the despatch of a police Level 1 response,” she explained. “Blackline Safety Europe, Ltd are very proud to be among the fi rst businesses in the UK to be accredited to the new upgraded BS8484:2022 standard.”
Blackline’s G7c is the all-in-one cloud-connected solution, disrupting the safety monitoring and gas detection space by integrating 4G connectivity and industry-fi rst capabilities to enable effi cient and reliable lone worker monitoring. The risk that an employee’s call for help could go unanswered is mitigated by connecting workers directly with live monitoring personnel, from wherever they are working. BS8484 enables certifi ed service suppliers to offer the highest level of emergency response, bypassing the central 999 system to make the process as effi cient as possible. Robust lone worker policies combined with innovative employee-worn technology can mitigate potential risks faced every day by those working alone. G7c’s lifesaving man-down and lone worker protection features integrated connectivity, which wirelessly links your team to live monitoring personnel along with True Fall Detection™ and no-motion alerts. Missed check-ins are immediately identifi ed when a team member fails to confi rm their safety status within a scheduled confi rmation timeframe. The G7c also provides reliable communication with two-way text messaging, two-way voice calling and push-to-talk options.
G7c’s emergency SOS latch generates an instant visible and audible alarm, alerting monitoring personnel should a worker be faced with a threatening or dangerous situation. The Silent SOS feature enables users to discreetly call for help by pressing the red latch for three seconds so there are no obvious signs of activation to an aggressor. This can be used in situations where a user knows they need help, but may not want to draw attention to themselves. G7c automatically communicates man down and gas alerts to monitoring personnel who are equipped to deploy a potentially life-saving emergency response when and wherever needed, up to and including the police. Worker location and safety status are easily viewed on a live map, so responders know exactly where to go. Connectivity is necessary to ensure the fastest possible emergency response. The live monitoring team follows tailored emergency response protocols and when required, escalates to the highest levels of police, ambulance or fi re service, only permissible when using a BS 8484:2022 certifi ed solution. G7c is the only BS 8484:2022-certifi ed combination lone worker monitoring and gas detection product currently on the market.

methane, oxygen, nitrogen and hydrogen. The reading is carried out in a matter of seconds, applying the thermal conductivity measurement principle. This technology ensures a longer service life for the measurement cell. The new WITT analyser is particularly user-friendly. It is operated via a 7” touch screen with password protection. Gas combinations can be selected and alarm limits defi ned quite intuitively. If the limits are exceeded, an acoustic and/or visual alarm is triggered, and (where specifi ed) an alarm acknowledgement requirement. All measurements can be viewed and exported via the measurement history function.

Unlike other devices on the market, the MFA 10.0 does not have to be recalibrated when the gas combination is changed. This simplifi es handling and saves valuable working time. Thanks to its compact dimensions, low weight and integrated handle, the new MFA 10.0 with its robust stainless-steel housing can be used as a mobile unit. However, it is also suitable as a stationary unit for continuous monitoring of gas mixtures. An RJ45 network connection, an analogue output and three potential-free relay contacts are available for signal transmission. The input pressure may be in the range of 1.5 to 10 barg, the temperature range in the range of -5°C to 50°C. 100 - 230V are required for operation.

INIR2 and INIR4 - for leakage detection of refrigerant gases
Cheaper, more effi cient and the most important: more environmentally friendly - this is how we could briefl y describe the advantages of the refrigerant R32 over R410A. With a Global Warming Potential (GWP) of 675, it has a much lower environmental impact, but the impact is still negative. This is why, for us and our planet safety, early detection of even the smallest leak of R32 gas is so important.
As SGX Sensortech, we would like to introduce you our latest INIR2 and INIR4 sensors for leakage detection of refrigerant gases with low Global Warming Potential (GWP).
INIR2 R32 INIR4 R32
The INIR2 and INIR4 are user friendly digital Gas Sensors, which are designed to use the latest SGX Sensortech’s infrared technology. They are primarily designed for the purpose of the gas leakage detection in both industrial and residential environments. Designed with the latest generation of power effi cient microcontrollers allows for high fl exibility and functionality. Temperature compensation, good accuracy and simple implementation into end user system make this sensor a perfect solution for gas leakage detection.
About R32 gas
The refrigerant R32 (difl uoromethane) is used in air conditioning systems and is increasingly replacing R410A. Refrigerant manufacturers and industry organizations also recommend switching to R32 as soon as possible. Its unquestionable advantage, which has undoubtedly contributed to its rapid rise in popularity, is the substance’s very low environmental impact. The global warming potential (GWP) of R32 is almost three times lower than that of the R410A it displaces. In addition, when fi lling the equipment, the amount of agent used can be reduced by up to 30% compared to the R410A it displaces, making it signifi cantly more environmentally friendly. Thanks to this parameter, it is also possible to reduce the size of pipelines and increases the effi ciency of the entire system. Another advantage of R32 gas is its cost, which is approximately 20% lower than R410A gas.
