EIN Flir covid19 400Many organizations are at risk of continued interruption to operations due to coronavirus and possible future pandemics. Thermal Imaging solutions from FLIR can help screen frontline employees for elevated body/skin temperature – a possible sign of fighting infection – before they enter crowded workspaces. Organizations that deploy these screening systems can help provide a more safe and secure workplace for a productive workforce.

Because thermal imaging cameras can detect and visualize heat, it seems logical to use one in non-contact screenings for elevated skin temperature (EST). But this application is not appropriate to every camera model or brand.

Thermal cameras that offer temperature measurement as well as a high thermal pixel resolution and accuracy are the best choice. Popular FLIR models like the Exx-Series and T-Series cameras meet these base requirements, but more importantly, also offer a built-in Screening mode designed for EST applications.

A thermal imaging camera can be an effective screening device for detecting individuals with an elevated skin temperature. This type of monitoring can provide useful information when used as a screening tool in high-traffic areas to help identify people with an elevated temperature compared to the general population. That individual can then be further screened using other body temperature measuring tools.

Although thermal imaging cameras are primarily designed for industrial and night vision uses, public health organizations have used FLIR cameras around the world at airports, seaports, office buildings and other mass gathering areas to provide rapid, efficient screening in high traffic areas. FLIR thermal cameras are particularly well suited to this because they can provide a temperature reading of a person’s face in a matter of seconds.

 

What to look for:

  • Accuracy/Resolution
  • Screening firmware
  • Service/Calibration/Support
  • Dual use of technology (Screening and maintenance)

 

How thermal imaging works

A thermal imaging camera produces infrared images or heat pictures that display small temperature differences. This allows thermal cameras to create and continually update a visual heat map of skin temperatures. In addition, FLIR thermal imaging cameras are sensitive devices capable of measuring small temperature differences.

Many of the FLIR thermal cameras that are appropriate for measuring skin temperatures also offer built-in functions like visual and sound alarms that can be set to go off when a certain temperature threshold is exceeded. The operator can then instantly decide whether the subject needs to be referred for further screening with additional temperature measurement tools.

As the thermal imaging camera produces images in near-real time, the total evaluation process takes mere moments, making thermal imaging technology very useful for rapidly screening large numbers of people.

Measuring the temperature of the human body

It is true that a person’s general skin temperature is typically not equal to the person’s core temperature. That does not detract from the use of thermal cameras to detect elevated skin temperatures, however. Thermal cameras are useful in this role because the goal is not to measure absolute skin temperature, but to differentiate people who have an elevated skin temperature compared to others while also considering the environmental conditions of the location.

Some FLIR camera models offer an elevated skin temperature screening mode that is helpful in comparing the person being screened against the temperature of other people previously screened. When in Screening mode, the operator can save ten thermal images of faces that the camera automatically averages as a reference.

Sound and color alarms

All areas on the subject’s face that are hotter than a predefined temperature value can be displayed as a designated color on the thermal image. This built-in alarm allows users to make an immediate decision regarding whether the subject may need further screening with additional screening tools. In addition, some FLIR cameras are equipped with an audible alarm that can be activated to sound if the detected temperature exceeds a predefined value.

A small investment to enable high-traffic screening

Airports all over the world are using FLIR cameras and have applied this methodology to screen people entering and leaving the country. It is a quick, non-contact method that is safe for both the camera operator and the people being screened.

Vallen CanadaIn the midst of the pandemic crisis, safety & MRO specialist Vallen Canada moved its 6,000 square foot West Edmonton, Alberta branch to a new 20,000 square foot location, enabling the branch to triple its inventory. How did the company keep everyone safe during the transition? Vallen Canada simply relied on its own expertise.

“We had to really do a good gut check on whether this was the right decision to move the branch during the pandemic,” says Vallen Canada President Karen Chester. “The reality is the show must go on… our culture is such that we pull together in tough times and we need to get the job done. The final step in the process was to make sure we keep people safe.”

Emergency HospitalsAs the battle against COVID-19 continues, medical providers all over the world are expanding their capacity to treat patients through the construction of temporary hospital facilities and tents. Eaton and its partners recently helped realize a project by the United States Army Corps of Engineers at Stony Brook University Hospital in New York, supplying essential power distribution equipment for four temporary medical facilities with the capacity to treat more than 1,000 patients. Construction on the facility is expected to be completed this week, with nearly 100 Eaton heavy-duty safety switches providing reliable power distribution to support life-saving ventilators and other devices.

Step-Down TransformersBy Max Ezzati

Step-down transformers allow any electrical product to be installed on 347V circuits, which is why many electrical contractors keep a few in their car stock. Selecting the correct step-down transformer ensures the physical dimensions of the transformer are as small as possible to fit easily in the junction box while keeping costs as low as possible. Here are our tips on selecting the best step-down transformer for your job.

Louis Poulsen Lamp SeriesIn 2020, Louis Poulsen and BIG Ideas present a comprehensive new lamp series, Keglen, especially characterised by its distinctive design as well as classic superior lighting quality.

The key pieces in the Keglen series are four pendants (Ø175), (Ø250), (Ø400) and (Ø650) that each provide their very own diffusion of light using a curved glass insert, which is built into and adapted to each version of the shade.

The main feature of the lamp is the organic shaped glass that sits perfectly beneath the cone as a small water droplet shaped by physics and cohesive forces in nature, says Jakob Lange, Partner, BIG Ideas.
