How to Improve Safety with a Personal Dust Detector from Dust Canary
June 9, 2023

Typically, we don’t give much thought to the air around us and even less to dust. In fact, we often use it to describe how little we are interested in something, comparing it to a speck of dust in our thoughts. But the reality of dust inhalation and its impact on our health and well-being is astounding. 


At Ultra Protect, we are experts in air quality and dust management and understand the implications of dust inhalation. We’re constantly looking for ways to improve air quality in the workplace and keep our customers safe. We have an innovative approach to keeping individuals safe. A personal dust detector  like DustCanary is a revolutionary way to keep those working in industrial and construction settings safe. But why is it important, and how does it work?


Dust Inhalation in the Construction Industry


Did you know that a staggering 12,000 deaths yearly result from occupational lung disease? This is as reported by the HSE, which also advises that regularly inhaling construction dust could lead to the development of various diseases. These include asthma, lung cancer, silicosis, and Chronic Obstructive Pulmonary Disease (COPD). 


From these diseases, a worker may be subject to permanent disability and premature death. 


Tasks that Create High Dust Levels 


Anyone working in the construction industry is at risk of high dust inhalation, and that is due to the many different tasks that produce high levels of dust. These include:


  • Cutting tiles and paving blocks
  • Scabbing or grinding 
  • Chasing concrete and raking mortar 
  • Dry sweeping 
  • Sanding 
  • Soft strip demolition 


The risk of occupational diseases caused by dust inhalation is high for those working in these settings. So, what options are available to minimise the risk and protect themselves? 


What is a Personal Dust Detector? 


Exposure to dust is often inadvertent as we naturally avoid large dust clouds and plumes. But what about when the dust isn’t visible and is stagnantly airborne? In this instance, it is difficult to avoid, and you are subject to constant inhalation. 


With the DustCanary personal dust detector, you can remain vigilant to accidental exposure to respirable dust. Plus, you can do so without heavy and bulky equipment! A personal dust detector is a wearable piece of technology that highlights the variability and hotspots of dust exposure. It provides a temporal record profile of dust exposure during a construction worker’s average day. 


When the dust levels precede the pre-set safe levels, the DustCanary detector will warn the wearer with audible and visual alarms. They can then remove themselves from the environment and the threat of respirable dust or don appropriate respiratory protection equipment (RPE). 


How Does the DustCanary Personal Dust Detector Work?


The DuctCanary detector works in real-time to detect, monitor and alarm about the levels of respirable dust in the given space. It does this through a robust Optical Particle Counting technology, which provides the qualitative monitoring of dust in an exposure range of 0–4mg/m3. 


The personal detector is sensitive to dust levels below 0.05mg/m3. It enters a dust protection mode at higher dust levels of 1mg/m3-4mg/m3. Each detector also has an inlet filter that should be regularly changed to remove non-respirable particles.


Benefits of a Personal Dust Detector 


Utilising a personal dust detector is a worthwhile investment for those working on the front line of dust exposure and others who may be in contact with dust less often, for example, managers and site supervisors. 


There are a number of benefits of using a personal dust detector that extend beyond the most important job of keeping the wearer safe in the first instance. The technology can also monitor the variations in dust exposure to understand and track the different sources of dust to help inform mitigation plans. 


Changes in dust levels are also monitored instantly by the personal dust detector, triggering preventative action immediately. The detector gives a reliable indication to the wearer on the most suitable course of action, such as to completely move away from the area with high dust levels or whether donning RPE is more appropriate. 


Plus, the personal detectors are capable of long-term monitoring, ensuring you can keep accurate records of how much dust a single person has inhaled over a given period. This allows for accurate data collection to improve safety on site.


Practicality


While beneficial for several reasons, the practicality of the DustCanary personal dust detector makes it a worthwhile investment for your workforce. Lightweight and easy to wear, the dust detector securely attaches to workwear without impacting productivity. Plus, each personal detector has a battery life on average of around 12 hours, ensuring a full shift is completed before it needs to be recharged. 


Invest in Safety Today


Ensure total safety compliance with Workplace Exposure Limits (WELs) with personal dust detectors from Ultra Protect. We offer a wide range of dust management equipment, including dust blockers and industrial vacuums

If you're responsible for health and safety in your workplace, you've probably encountered the terms "workplace exposure level," "TWA," and "STEL." But what do they actually mean, and why do they matter for dust management? The simple answer: these are legal limits set by the Health and Safety Executive (HSE) to protect workers from harmful dust exposure. If you're not monitoring them, you're flying blind and potentially breaking the law. What is Workplace Exposure Level? A workplace exposure level (WEL) is the maximum amount of a harmful substance that a worker can be exposed to during their working day without suffering adverse health effects. For dust, it's measured in milligrams per cubic metre of air (mg/m³). The HSE sets these limits based on scientific evidence about how different dust types affect human health. Different dusts have different exposure limits because they pose different risks. For example, the WEL for respirable crystalline silica is far stricter than for general inert dust, because silica is significantly more harmful to the lungs. Think of it this way: the WEL is your compliance baseline. If dust concentrations in your workplace stay below this limit, you're meeting your legal obligation. If they exceed it, you have a duty to investigate why and take corrective action. Download the HSEs guidance on workplace exposure limits If you want to understand the levels in your workplace contact us about our silica air sampling services TWA: The 8-Hour Average TWA stands for Time-Weighted Average, and it's the most commonly referenced exposure limit. The TWA measures the average concentration of a substance over a standard 8-hour working day. Here's why that matters: dust exposure isn't constant. Workers might face high concentrations during certain activities (cutting, grinding, demolition) and lower concentrations during others. The TWA accounts for these fluctuations by averaging them out over the full shift. This recognises that workers can tolerate brief periods of higher exposure, provided the average stays within acceptable limits. For example, the current WEL for respirable crystalline silica is 0.1 mg/m³ as an 8-hour TWA. This means that if a construction worker is grinding stone for part of their shift but doing lower-dust tasks for the rest, the daily average should not exceed this level. The advantage of TWA is that it's practical for real-world work. Few jobs maintain constant dust levels. The disadvantage is that it can mask dangerous peaks, if a worker is exposed to very high concentrations for a short period, the TWA might still look acceptable. STEL: The Short-Term Exposure Limit STEL stands for Short-Term Exposure Limit, and it's your safety net for peak exposures. A STEL is the maximum concentration a worker should experience during any 15-minute period in a working day, and no more than four such periods should occur, with at least 60 minutes between them. The STEL exists precisely because the TWA can obscure dangerous peaks. Imagine a worker exposed to very high silica dust for 15 minutes whilst cutting stone, then lower levels for the rest of the day. The TWA might be within limits, but those 15 minutes could still cause significant lung damage. There should be a maximum of 4 STEL's in a single working day and there must be at least 60-minutes between each STEL period. Not all dusts have a STEL, but those that do (like respirable crystalline silica) reflect a recognition that short, intense exposures carry genuine health risks that the 8-hour average doesn't capture.
