Focus on Personal Safety at Work 25
The essentials of air sampling So what is an essential part of air sampling that does not include
all the usual questions of Who, Where, When and What? The equipment!
The first is the sampling device, whether that may simply be a filter in a device such as the IOM sampler for dust and particulates or a sorbent tube for gases and vapours. The second is the sampling pump itself. Does it have the required Intrinsic Safety certifications, the performance requirements for the application in hand, and the necessary power to meet the required run time?
All very necessary and obvious, but what about ensuring that the flow rate is measured accurately?
This is where another essential part of the air sampling procedure comes in, the air flow calibrator and, more specifically, [SKC’s chek- mate].
Most air sampling is performed under vacuum and is a volumetric flow measured in either litres per minute for aerosols or millilitres per minute for gases and vapours.
The current [HSE MDHS 14/4] Gravimetric Methods for the Determination of Inhalable, Thoracic and Respirable aerosols refers to testing of sampling trains before and after sampling to a measurement uncertainty of +/- 2.5%.
With its accuracy specification of ±1% of reading and display resolution of 0.001 litre/min, or 1 ml/min, the chek-mate significantly exceeds the requirements of MDHS 14/4.
The unit displays continuous real time volumetric flow and is provided with a UKAS/NIST traceable calibration certificate.
If we look back just a couple of years, we will see that most air sampling pump calibrators whether electronic, bubble type or a Rotameter were, and most still are, stood on the bench. The reason being is that they have to be vertical to ensure accuracy and indeed, correct operation in order to work at all.
Several of these have some form of piston unit so are of large mass, which means that they need time to stabilise to room temperature, are sensitive to being moved around, and require a firm, stable base to sit on.
The SKC chek-mate is not of this type, it’s different. Being an orifice type flow meter, it is truly portable, can be held in the hand and is orientation free, so it is incredibly versatile without losing accuracy and takes significantly less time to stabilise for use.
The unit has no moving parts, so there is very little to possibly go wrong. It is very simple to use; just connect up, switch on with a press of the only button and take the readings.
The readings are displayed on a large liquid crystal display, showing a moving average and it utilises a standard 9 volt battery so does not need a mains power source.

Air sampling pump wins
new product of the year award Casella has won Occupational Health and Safety’s 2019 ‘New Product of the Year Award’ for its VAPex Personal Low Flow Sampling Pump.
email: For More Info, email: email:
Casella’s VAPex Personal Low Flow Sampling Pump was selected as the best new product in the Industrial Hygiene: Air Sampling category by a panel of three highly qualified judges.
Tim Turney, Global Marketing Manager at Casella, said “We’re thrilled that the VAPex has been recognised among this year’s best products by a publication as well regarded as Occupational Health & Safety. We’re proud that the user-focused features of the VAPex have put it ahead of other air samplers. It follows in the footsteps of our other award-winning products, enabling our continued growth in the air sampling market.”
The 11th edition of the annual awards program was highly competitive, as Occupational Health and Safety (OH&S) editor Sydny Shepard, explains: “OH&S’ ‘New Product of the Year Award’ saw an outstanding number of entries for 2019, proving that industry manufacturers are dedicated to producing products that not only optimise worker safety, but are comfortable, practical and convenient. Entries this year received top remarks from the judges, who complimented efforts to bring more innovative products to the industry.”
“I’d like to congratulate all the 2019 winners and thank the companies that participated. The mission of OH&S is to inform readers about the best new products available to solve their health and safety challenges, and this contest is instrumental in our outreach to the industry.”

Take action to protect employees from hearing damage with Casella’s NoiseSafe Casella, air sampling, noise and vibration specialist, has launched an advanced and reliable software package for its personal dosimeter (the dBadge2), NoiseSafe. When used alongside Casella’s dBadge2, it is the ideal tool for fast and efficient reporting and analysis of noise exposure levels.
In the UK, over one million employees are exposed to levels of noise at work, which puts them at risk of noise induced hearing loss (NIHL). In fact, last year 23,000 workers in the UK reported work-related hearing problems, with workers in the manufacturing, food and construction sectors most at risk due to noisy working conditions.
Casella’s NoiseSafe software saves the user time with its instantaneous reporting on an employee’s noise exposure levels. Linked to the dBadge2, the software downloads a typical eight-hour workplace recording in just a few seconds. Audio and motion can be analysed to determine if any of the data is erroneous, which can be quickly and easily removed from exposure data, giving confidence in the results.
Tim Turney, Technical Product Manager at Casella explains, “The new software is designed to make noise assessments easier for managers concerned with the health of their employees. The graphs and data produced can easily be customised depending on the user’s requirements, making reporting pain-free and quick.”
Casella’s NoiseSafe software is available with any purchase of the dBadge2 from April 2019. Casella is dedicated to reducing occupational health and environmental risks and supporting businesses with their monitoring and analysis needs.
