The Dangers of Dust in the Workplace
August 10, 2022

Dust.  It can kill

Not just today, but years down the line


Don't risk your health, protect your lungs from dust


Construction workers die every week from lung diseases caused by exposure to dust. Many more suffer from severe chronic long-term lung conditions.

 

Don’t make the same mistake as construction workers who have not realised the health risks of exposure to dust and have worked unprotected.



Make sure you are aware of the risks and know what to do to stay safe.

DUST IS A SILENT AND SOMETIMES INVISIBLE KILLER 


Dust particles can be 100 times smaller than a grain of sand. You don’t need to see them to breathe them in – they can literally be the unseen killer. Once in your lungs, dust will start causing damage and is quite often irreversible.

 

For most, exposure to dust leads to long-term breathing difficulties and lung disease which greatly effects the quality of life. Unfortunately, it gives you very little warning as the damage is often not visible for many years and it can then be too late.

 Make sure you are aware of the risks and work in ways that always protect your lung health.

 

The many types of dust that you may experience in the workplace can be categorised into two types.


Inhalable dust is the larger of the two types of dust, most of which can be filtered out naturally in your nose and throat.


 Respirable dust is the more dangerous of the two.



In this case, the dust particles cannot be filtered out by your nose or throat due to their small size. Therefore, they can cause you serious health problems with prolonged exposure by penetrating the pulmonary alveolar region of the lungs.

 

Dust exposure in the workplace is an issue both employers and employees need to be aware of, as it can lead to many different health problems.

Dust exposure can cause and exacerbate, ranging from the mildly serious to the life-threatening.


Lung cancer – With an estimated 43% of annual deaths from lung disease at work being due to asbestos and non-asbestos-related lung cancer, exposure to dust is a serious health hazard.


Chronic obstructive pulmonary disease – 33% of current annual deaths from occupational lung disease are from Chronic Obstructive Pulmonary Diseases such as emphysema and chronic bronchitis.


Silicosis – respirable crystalline silica (RCS) causes irreversible effects of inflammation and fibrosis of the lung tissue, if exposed to over a prolonged period. Symptoms include a persistent cough and shortness of breath and can often become worse years after the initial exposure. An estimated 500 construction workers die each year from silicosis


Asthma – dust exposure radically affects how this common and long-term chronic disease is managed. Respirable dust particles are small enough to get right into your lungs, causing inflammation and swelling

of your airways, inducing your asthma symptoms

DUST - A BIGGER GLOBAL KILLER THAN SMOKING

Some frightening facts about the dangers of dust

  • Dust costs the UK economy over £20 billion a year.
  • More than 3,500 builders die each year from cancers related to their work.
  • The HSE reported that there were around 39,000 individuals suffering breathing and lung problems in the UK and there are around 8,000 deaths per year as a result of occupational cancer.
  • Health & Safety Inspectors initiative to check & investigate businesses.
  • Thousands of ill-health and working days lost due to dust.
  • Around 100 times as many workers die from diseases caused or made worse by their work than are killed in construction accidents
  • Legal requirements in the UK – the government run Health and Safety Executive (HSE) have made dust a primary focus, giving out fines of up to £2000 where inefficient, the wrong or no dust extraction is being used.
  • Minimum of a Class M dust extraction system required in commercial and industrial.
  • Last year, tiny particles of sand, wood and asbestos contributed to 12,000 deaths from lung disease in the UK, according to the Health and Safety Executive.
  • HSE will carry out excess of 1000 visits each year.
  • HSE’s inspectors across Great Britain will be targeting construction firms to check that their health standards are up to scratch during inspection initiative, starting on Monday 4 October 2021.
  • This year inspections will focus on respiratory risks and occupational lung disease, looking at the control measures businesses have in place to protect their workers’ lungs from construction dust including silica, asbestos and wood dust.
  • HSE’s chief inspector of construction, Sarah Jardine, said: “Around 100 times as many workers die from diseases caused or made worse by their work than are actually killed in construction accidents.

Dust Awareness Schemes & Risk Assessments


Dust Awareness Schemes and Risk Assessments

The effects of dust in relation to soiling (local amenity) and health can be a concern in the planning process and visible dust emissions and deposition can lead to complaints.


Dust can be generated in a number of processes including during demolition and construction activities, mineral activities such as quarrying, industrial processes such as cement batching, and waste management.

 


We provide a comprehensive Dust Awareness Schemes and Risk Assessment complete with solutions.

 

  • Dust Monitoring
  • Preparation of Dust Management Schemes and Plans
  •  Input into Construction Environmental Management Plans (CEMPs) to mitigate the impact of sites in relation to dust emissions
  • Providing evidence to planning appeals

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.
