Ashtead develops bespoke dust monitoring/alarm solution

Following advice from the Health & Safety Executive (HSE), a large UK manufacturer was required to monitor airborne particulates in and around its paint shop, and to automatically raise visual and audible alarms when potentially dangerous conditions arise. Ashtead Technology was therefore contacted, and Jay Neermul, Environmental Sales Manager, visited the site to assess the requirements.

With remote communication and the ability to measure all of the key dust fractions simultaneously, Jay concluded that the most appropriate instruments would be the TSI DustTrak Environmental 8543 MCERTS Outdoor Dust & Aerosol Monitors (TSI DTE). “By continuously monitoring total PM, PM10, PM2.5 and PM1, these instruments provide a complete picture of the particulate levels that represent a threat to staff health,” he comments. “With MCERTS certification these monitors also have the proven levels of performance that are required to operate continuously and reliably.”

The TSI DTE instruments continuously monitor particulate levels and transmit data to a cloud-based system which can be accessed via PC or mobile APP. This provides an opportunity to view secure monitoring data 24/7 from any location, which means that staff will be able to correlate process conditions with aerosol levels so that opportunities for operational improvements can be identified. The system is also able to issue alarms via text or email, however, this application demanded visual and audible alarms so that staff can be evacuated immediately. The TSI DTE does not provide this function, so Ashtead’s engineers developed and trialled a solution that incorporates the advantages of the monitoring system with a bespoke audible and visual alarm capability.

The resulting monitoring system demonstrated full compliance with the site’s monitoring requirements, so three systems were ordered in July 2019 and delivered in the first week of August.

“This project exemplifies Ashtead’s ability to develop a monitoring solution that meets the precise needs of a client,” comments Jay Neermul. “Our website details the wide range of standard products that we stock, but a quick call to our technical staff allows customers to ensure that they buy or rent the best equipment for their specific application, even if that requires systems engineering on our part.”

Beyond Expectations: Bam Ritchies and Cassella

The collective movement for solving issues surrounding work related ill health continues to gain momentum, highlighted in the HSE Help GB Work Well Scheme calling for “greater awareness of the harm, costs and preventability of the issue” which should “drive collective action to improve health outcomes”. In an effort to raise awareness of dangerous substances in the workplace, the European Agency for Safety and Health at Work (EU-OHSA) has recently launched a ‘Healthy Workplaces Manage Dangerous Substances campaign’ to promote a culture of risk prevention. The campaign is intended to heighten awareness of risks linked to exposure, targeting workers with specific needs.

Each year, there are 12,000 lung disease deaths estimated to be linked to previous exposures at work. A 2017 HSE report highlighted 18,000 annual incidences of self-reported work-related breathing or lung problems in the previous 3-year period up from the 10,000 per year actually estimated. Although Health and Safety Executive (HSE) statistics show that work related deafness incidents have generally gone down since 2008, 20,000 people a year still suffer with work-related hearing problems.


BAM Ritchies prides itself on being one of the first geotechnical contactors to carry out extensive hygiene monitoring of its workplaces. The company is a division of BAM Nuttall, a £60 million business with 400 employees throughout the UK providing ground engineering services for government, local authority, utilities and public/private companies.

Mark Sherwood has been an occupational hygienist at the company for 3 years, responsible for dust, noise fumes and vibration monitoring nationally for BAM Ritchies as well as supporting BAM Nuttall. A typical day includes a range of dust assessments, from wood, welding fumes, quarry dust, and respirable crystalline silica. He undertakes personal exposure monitoring across the workforce to control exposure levels and where necessary, provides recommendations with preventative health measures to control any hazards from dust, noise and vibration. Options such as elimination, substitution and engineering controls are explored, or PPE/RPE is recommended from the accurate exposure measurements.

When Mark first started as an occupational hygienist, the workers were curious, asking questions about the equipment, and the reason for it being used. Individuals were interested to learn the results from the monitoring equipment and what the data meant. To ensure Mark was able to establish accurate measurements for dust, noise and vibration exposure, working closely with regulatory limits, he used Casella’s equipment, and still does today.

To adhere to compliance with EH40 2005 workplace exposure limits (WELS) Mark uses 8 Casella lightweight, rugged bodily worn Apex2 personal air sampling pumps to monitor contaminants that may pose a health risk, including hazardous dusts like silica in quarrying or fumes during welding or dust created during evacuation. Noise exposure is measured with the 620 Sound Level Meter and a Noise kit which includes 6 dBadge2 dosimeters for noise at work applications, recording the audio of noisy operations, storing noise dose and performing octave band analysis, as well as general environmental measurement. This ensures regulatory compliance and encourages improvement initiatives to protect worker hearing. This thorough method ensures exposure levels are assessed with the wireless capability via Casella’s Airwave app meaning monitoring does not need to disturb worker operations and data can be transmitted for assessment and alerting purposes direct to inboxes of nominated personnel.


BAM Ritchies prioritises protecting their people. Mark had previously used Casella’s HAVex meter to measure the vibration levels of the tools employers were using to ensure they weren’t over exposed to hand arm vibration during their daily routine. However, a proactive initiative by senior management has since removed vibration tools and the need for monitoring. In the event of there being no alternative method, a request to use a vibration tool requires a Permit to Work system authorised by the appropriate/nominated person.

There are instances where Casella’s noise and dust monitoring equipment has resulted in positive changes across sites around the country. This has included an additional dust extraction system at a material testing laboratory in Scotland to further eliminate risk of substance exposure. Results from noise monitoring at quarries fortified the introduction of filter 3 hearing protection to ensure workers have the upmost protection, as a precautionary method rather than an essential one. Other sites have also decided to upgrade RPE with the same sentiment of protecting workers as much as possible with the current and future exposure levels being carefully considered.

Through Casella’s equipment, Mark is also able combat one of his biggest issues – time. He praises the equipment for providing information that a hygienist is able to interpret and feedback to management in a summary/reporting format. “My work involves me travelling around the country to ensure I meet as many employees as possible and that their working environment does not impact their long-term health. Casella’s equipment enables me to work quickly and efficiently, with the confidence that all appropriate data is being accurately captured.”

The very nature of how Mark’s role is perceived by staff has also completely shifted. Now, individuals instantly understand the value behind what Mark is doing, knowing how the equipment works and the role it plays in protecting them from potential hazards. “I make it a priority to understand different working patterns and movements in a working day so that my role can slot neatly into this. Workers appreciate this as it’s clear their time and tasks are being valued”.

Bam Ritchies prides itself on being a company that achieves extraordinary things, pushing boundaries and providing ground engineering solutions that bring engineering to life. Without a healthy workforce this vision cannot be realised. “Casella site monitoring equipment is a crucial part of my everyday kit that I carry everywhere, without fail” said Mark. The company is an industry leader for its effort to monitor and protect its workforce, and this process has now come full circle, with the workers completely in tune with the benefits and process, collectively working towards a healthy working environment.

Cassella Solutions Air Sampling

Casella launches game changer in air sampling calibration – Flow Detective™

Casella, air sampling, noise and vibration monitoring specialist introduces the Flow Detective™ air sampling pump calibrator. The product is the first in the industry with the ability to measure pulsation, with a 70-hour battery life; the longest on the market and double the duration of competitive products.

There is an estimated 18,000 new cases of breathing or lung problems a year caused or made worse by work, and an estimated 12,000 deaths from lung diseases linked to exposure at work. It is an employer’s duty to protect the health of employees through health surveillance and exposure monitoring. Air sampling is crucial and Casella’s latest Flow Detective™ is a robust solution allowing air sampling pumps to be calibrated, ensuring the pump has the correct flow, with traceable measurement results.

The Flow Detective™ is an electronic flow meter calibrator, designed to measure the flow of air sampling pumps to within 2% accuracy. The device will be the first on the market with a Bluetooth connectivity, through Casella’s Airwave App. Airwave is the only app of its kind providing remote control for dust and noise monitoring devices, enabling calibration results to be sent via email, ensuring improved traceability and pump calibration procedures. As well as detecting air flow, the Flow Detective™ is the first calibrator on the market with the ability to measure pulsation, indicating if the air flow pulsation exceeds 10%. Air sampling pumps must have a pulsation level less than 10% if they are to adhere to ISO 13137. Excessive pulsation means an unsteady flow and has a detrimental effect on the ability of cyclone air samplers to collect the correct fraction of respirable dust.

The Flow Detective™ can be used with any manufacturers air sampling pumps, but for Casella’s Apex2 personal dust sampling pump, the Airwave App allows for closed loop airflow calibration with the ability to remotely set the flow via Airwave, so no manual settings have to be done on the pump or flowmeter, drastically saving time when calibrating pumps.

The Flow Detective™ will save professionals additional time due to its simple user inter-face, colour-screen and wide flow measurement range, which can be used for all personal flow use with any pump. The Flow Detective calibrator saves significant time compared to other electronic or traditional bubble flow meter calibration methods minimizing set up prior to undertaking calibrations and enabling tagging pre and post calibration data. The device is also functional for both dust and vapour sampling from 25mL to 5L per minute. As it also measures temperature and pressure, this gives peace of mind that the units will always be accurate, regardless of the environment.

Automotive Component Supplier eradicates compressed air for removing debris

DURA Automotive Systems is an independent designer and manufacturer of automotive components, including control systems, exterior systems and lightweight structural systems. DURA markets its automotive products to Global Original Equipment Manufacturers (OEM), including leading Tier 1 automotive suppliers.

At Dura Automotive Body & Glass Systems, based in Birmingham (UK) they manufacture products that includes Steel and Aluminium Doors, Impact Beams, Glass Encapsulation, Plastic Cappings, Exterior Trim and Electric Park Brakes.

The Problem
Within their large facilities, DURA operative regularly handle a variety of materials that includes glass, plastic, steel and aluminium alloys.

Manufacturing high volume parts from these materials inevitably creates a working environment where machine operators are being frequently exposed to airborne particles and fragments. So dust and swarf can quickly contaminate clothing and even stick to operator’s skin.

“The use of compressed air lines to clean oneself is a disciplinary issue, however some have previously used this”, states Olii Lebrun, Engineering Manager for Dura Automotive. He continues, “As a company dedicated to Health & Safety best practice we searched for a solution that would eradicate the use of compressed air lines for removing this, and any other debris, as it is a dangerous practice phentermine weight loss with potential to cause gross harm to operators. A safer alternative had to be found”.
The Solution
To address the problem, DURA installed a wall-mounted ACI JetBlack blow-off cleaning station in the work zones that have the highest exposure and / or risk.

“Since the JetBlack system operates on the principle of low pressure, high volume airflow it is categorically safe to use, even directly against human skin. This technology also ensures strict Occupational Safety and Health Standards (OSHA) are responsibly met by the company. The installation of our JetBlack unit ensures all DURA personnel have an effective and efficient way of clean down in the safest possible manner”, continues Oli.
The Outcome
Oli concludes, “The installation of JetBlack cleaning stations has provided the ideal workplace solution for removing dust and debris safely. The ease of use in which the unit operates and functions has been a triumph with all integrated teams and employees. We would highly recommend any company that is currently seeking replacement of compressed air lines to look no further and use ACI JetBlack Cleaning Stations!”.
