Air Monitoring 33 Standalone warning system reduces risks of lightning hazards


Lightning strikes the ground in the UK around 300,000 times a year, putting at risk those who are often outdoors in exposed, unsheltered locations. Although there is no full-proof protection from lightning, measures can be taken to reduce the risk of getting struck. With this in mind, meteorological equipment specialist Biral is offering its BTD-200 self-contained, standalone lightning warning system so that employers can take precautions to prevent exposure to lightning and ensure their workers’ safety.


Statistics show that 30-60 people are struck by lightning each year in the UK and on average, three (5-10%) of these strikes are fatal. Because of this, workplaces have a duty of care to ensure the health, safety and welfare of their workers under the Health and Safety at Work Act 1974, so if staff are working outdoors in exposed areas a lightning safety plan should be in place. Many victims of lightning strikes are struck because they do not behave correctly during a storm, or do not have sufficient warning to get to a safe place. Workers should not begin any task they cannot quickly stop when signs of bad of weather are approaching and must follow a lightning safety protocol to vacate open spaces quickly.


The only reliable and consistent way of issuing a lightning warning is with a dedicated lightning detection system. About 90% of thunderstorms are already producing lightning by the time they are within 12 miles (20 km), so a professional, real-time lightning warning system should provide adequate notice of an approaching storm. However, in the case of the remaining 10%, the first flash will occur nearby or overhead – which is the most dangerous. Therefore, it is important not to rely on systems which only detect lightning as it occurs, as these cannot provide any advanced warning of the threat of overhead lightning and its implicit danger. Ideally, what is required is a reliable thunderstorm detecting system which gives adequate warning time to prepare before the storm moves overhead and one which is also able to warn of the threat posed by potential overhead lighting before it has begun, if the thunderstorm is developing overhead.


For the best chance of getting a thunderstorm threat warning, the detector should be able to alert for both distant lightning and the presence of a strong electric field at a location. This strong electric field is indicative of a lightning threat developing overhead – so potentially a very serious situation and one to take immediate action over. The innovative BTD-200 lightning warning system from Biral is able to do both. It detects distant lightning up to 22 miles away as well as warning about a developing strong electric field overhead, even if there is no lightning being produced. The Lightning Works software will then alert the staff and managers to these threats in real time, allowing them to review and manage the situation and to staff to the potential danger. It can also activate warning sounders automatically if required. The BTD-200 lightning warning system represents the next generation of lightning detection and warning system. It has been developed from proven professional technology currently used worldwide at airports and by national meteorological organisations.

and Legal Standings In todays’ world of ever-increasing liability and risk aversion, it is so important you make the correct decision with your instrument calibration. Does your calibration certificate provide you with a bullet proof line of traceability and have a legal standing in a court of law? Having a UKAS accredited calibration helps you ensure your measurement system has the fundamental foundations for legal interrogation and provides you with added confidence in your measurement system. The Young Calibration laboratory is UKAS accredited (Lab 0604) for air flow, fluid flow, electrical, air velocity, pressure and temperature simulation.


UKAS Gas and Fluid Flow Calibration


High accuracy water meter calibrations for infusion, batch, volume flow rate and mass flow for all types of flowmeters from 0.1% accuracy. Hydrocarbon flowmeter calibration of turbine, helical, gear and coriolis flowmeters from 0.4% accuracy. With over five accredited air flow calibration rigs flowmeter calibrations across 1 cc/min to 1250 l/sec can be completed on laminar, thermal, variable area, vortex and turbines flowmeters.


UKAS Air Velocity Calibration


The UK’s leading high accuracy UKAS accredited wind tunnel, covering 0.05 to 80 m/s. Air velocity calibrations and anemometer calibration services are completed in the UKAS accredited wind tunnels, offering extreme accuracy in both low and high-speed wind. The offers independent, UKAS accredited air velocity calibrations for all types of pitot tubes, isokinetic probes, omni-spherical probes, vanes, cups and thermal anemometers.


The World Health Organisation identifies Radon gas as the second risk factor in the occurrence of lung cancer with over 10% of cases linked to excessive Radon exposure.


We are all exposed to radiation from natural and man-made sources. Radon is a colourless, odourless radioactive gas formed by the radioactive decay of the small amounts of uranium that occur naturally in all rocks and soils.


Radon in soil is the biggest source of Radon in indoor air and presents a greater risk than Radon in drinking water. Properties built in certain areas around the world are more likely to contain high levels of Radon due to the underlying geology and varying amounts of uranium present. When it permeates the ground into open air, Radon is quickly diluted to low concentrations. However, if it rises into a building, it can become trapped and increase to dangerous concentrations. Alpha particles produced by the radioactive decay of inhaled gas cause irreparable damage to lung cells.


The Euro-Gas Radon SS sensing component detects field range of 0-65,000Bq/m3 levels. With a uniquely designed high performance phototransistor sensor, it has a standard range of 1750pCi/l Rn. Its easy-to-use advanced technology makes it an ideal sensor for installation into both portable and fixed detection equipment in air quality and gas detection, delivering a complete set of information for instantaneous and average Radon alpha particle concentrations.
