SO EVERYONE IS STILL SCREENING FOR COVID-19 –
BUT IS IT EFEFCTIVE?
On 28 February our president announced the return to Lockdown Level 1, but we’re definitely not out of the woods. In fact, we’re of the opinion that screening now becomes even more important again to ensure we do not have another spike in infection rates.
But, when it comes to screening, it is so important to understand that we are not taking body temperatures but skin temperatures with the IR scanners that most companies and organisations use.
The norm also seems to have become to scan the wrist for some reason, but actually, the best place to take an accurate reading is from the inner canthus of the eye (tear duct) as this is the hottest part of the body, and is as per ISO Screening Standards. Or you can take a reading on the temporal artery on the forehead. i.e. between the eyes where the unibrow would meet or just above, on the forehead.
The reason why we take from these two areas is that these are normally the hottest areas of the body and research has shown that there is a direct correlation between the canthus of the eye (skin) and body temperature.
WHAT IS THE CORRECT TEMPERATURE SCREENING RANGE?
The devices that will most likely be used to complete temperature screening of their pupils, staff and customers will be contactless IR Thermometers due to their cost.
Most IR Thermometer’s range is between 32 deg – 42.5 deg Celsius. Most IR Thermometers also have a surface and body setting – ensure you correctly set these devices for ‘body’.
To ensure that correct readings are attained bearing in mind that the statutory alarm or threshold has been set by government at 38 deg C, hence most IR thermometers alarm setting have been set at 38 deg C.
What is very important to note however is that all testing must be completed in an environment that has a constant temperature of between 23 – 27 deg C. This will be challenging for South Africa going into winter this cannot and will not be achieved in the mornings where our ambient temperatures can drop as low as -3 deg C, and hence a vital floor in setting the fever threshold at 38 Degrees.
WHEN IS THE OPTIMAL TIME TO SCREEN INDIVIDUALS FOR COVID-19?
Understanding that there is a direct relationship between skin temperatures and ambient external temperatures, necessary adjustments of devices need to be assessed.
Many people using IR thermometers have already asked the question ‘why in the mornings are we getting “LO” on our thermometers – the answer is simply, the skin temperature has dropped below what the thermometer can read, as well as people possibly not understanding where readings can and should be taken from.
Therefore in the mornings many people taking temperatures will often get a “lo” reading or temperatures between 32.5 – 33.8 deg and this is purely due to the ambient outside temperature affecting the skin temperature.
The problem that very few people realise, is that the alarm threshold or ‘Fever Temperature’ on the device used, needs to be dropped in accordance with the average skin temperature, for instance in the mornings when temperatures are attained at between 32.5 and 33.9 an average needs to be established which in the above case is 33.2 deg, add a differential of 1.5deg C and your fever threshold is now 34.7 and not 38 degrees Celsius.
The problem with taking temperatures more so in the morning, is that should a person have a fever or mild fever, due to the setting of the fever threshold at 38 deg, these people would still gain entry to the place they are entering, as the ambient temperature has decreased their skin temperatures below the “alarm threshold” of 38 deg.
HOW DO WE PREVENT INCORRECT READINGS WHILST SCREENING?
Organisations need to be proactive in setting up a ‘constant’ ambient environment prior to each screening session (as three have been dictated during the course of a school day) and understanding that they are taking skin temperature and not body temperatures and the anomalies that can occur.
When screening it is important to keep the environment temperature stable and the individual screened has to be given 5 – 10 minutes within the confines of the screening environment for their skin temperature to adjust accordingly and a second test completed.
In the adverse affect, where the skin temperature does not drop after allowing that person to remain within the confines of the ambient temperature and remain at 36.5 deg we decern that that person could well now have an EST (Elevated Skin Temperature) and now requires a medical thermometer to again check that they in fact do or don’t have a relevant fever or EBT (Elevated Body Temperature) On checking with a medical thermometer by medical personal then again that person will either be allowed or not allowed to proceed dependent on the medical practitioner completing the reading of the temperature and the screening process.
Remember that having a fever or EST or EBT does not necessarily mean that you have Covid 19 or the Corona Virus – only further testing will and can determine that.
PREVENT BREAKDOWNS BEFORE THEY HAPPEN
WITH THE A320
Condition monitoring (CM) is the process of monitoring machinery in real-time and is a major component of predictive maintenance.
Heat is one of the most important indications of failing components. As such, thermography can be successfully applied to the monitoring of high-speed bearings, fluid couplings, conveyor rollers, electrical contacts and terminations, motors and engines, and many other industrial processes.
Intervention in the early stages of deterioration is almost always more cost-effective than allowing the machinery to fail and losing valuable production time.
Using Thermographic condition monitoring for CM has a unique benefit in that the actual heat dissipation that represents normal service can be seen and conditions that would shorten normal lifespan of equipment, can be addressed before failures occur, large financial outlays and maintenance downtime are required.
EARLY FIRE DETECTION & PREVENTION ADVERTS DISASTER
Fires that are not caught early or extinguished quickly can cause serious financial, environmental, and commercial distress for a company, as well as distress to the community. Most current fire systems are designed to contain a fire once it starts—which isn’t always the most effective solution. A system that allows companies to avoid fires or stop them before they spark can save lives, save money, and prevent downtime.
Fire is caused by rapidly increasing and excessive heat. As the heat on an object continues to rise it eventually bursts into a flame combusting and spreading even faster. However, if a fixed-mount thermal imaging camera is trained on the target area, temperatures can be monitored to catch the rising heat before the target combusts.
Fixed-mount thermal cameras provide live temperature data updates up to 60 times per second to find rapidly heating areas before they catch fire. These thermal smart cameras use built in software to isolate regions of interest (ROIs) and report minimum, average, and maximum temperatures from the regions the user creates.
Live data can be analysed internally by the camera to report unfavourable conditions or be connected to other devices such as PLCs and computers to implement additional fire prevention action.
ELECTRICAL INSPECTIONS WHEN THEY COUNT
When electrical components and equipment break down unexpectedly, the result may be unplanned downtime, costly repairs and production loss. There is also the increased risk of fire due to electrical short-circuits or cables burning out.
That’s why it is important to perform routine checks to ensure that your electrical distribution systems and machinery are in proper working order. Often this equipment is housed in enclosed cabinets or in hard-to-reach places making them difficult to inspect for impeding failures.
Fortunately, electrical components and machinery with working parts shows signs of overheating before they fail. Thermal technology can provide key information that the eye cannot detect and can prevent malfunction and disaster.

WE’RE PROUD TO INTRODUCE SEC-Q-FENCE
It is with great pride that we introduce our latest product Sec-Q-Fence.
Our new Sec-Q-Fence system is designed and developed to bring maximum perimeter protection to a site, without impeding visibility (which is important for guard patrolling or video surveillance).
Our new Sec-Q-Fence is an anti-climb fence which has been universally accepted as the most secure form of welded mesh panel, commercially available with significant inherent advantages over products such as chain link fencing or other forms of welded mesh fencing, owing to its unique configuration.
Our new see-through fencing is ideal for both residential or commercial property security measures. Our range of products have been designed in such a way that it offers customers a completely customizable fencing solution, from welded mesh panels to a selection of spikes and posts, which affords them the opportunity to build the perfect security barrier specific to their lifestyle requirements.
Sec-Q-Fence is highly durable and lasts much longer than conventional fencing. The Fence is ‘anti-cut’ which means that it cannot be cut by conventional tools and its coatings makes it weather resistant, making it last even longer.
Our coating ensures that the base wire is coated to perfection using the very latest Plascoat technology.
This process ensures a bond to the base metal to ensure no moisture can penetrate between base metal and the Plascoat. This ensures a long lifespan in very hostile environments.
We guarantee that we never compromise on our quality standards. This product aims at ensuring cost effectiveness and service excellence.
We encourage you to give us the opportunity to assist with any fencing requirements you may have.
We also provide gates that are made in the same durable fashion as our Sec-Q-Fence to ensure complete your see-through perimeter security.
We manufacture two levels of protection. Residential will be a lighter manufactured gate as the threat is significantly less than a commercial structure.
