Importance of Dust Extraction
According to an HSE report, Occupational Lung Disease Statistics in Great Britain 2023, approximately 12,000 people each year die of lung disease deaths related to dust exposure. Statistics from the Labour Force Survey (LFS) uncovered that in the last three years there were approximately 19,000 new cases of lung disease amongst people employed in the previous year, 43,000 new or longstanding cases, and 152,000 new or longstanding cases amongst people who have ever been employed.
It's clear that exposure to dust has serious consequences, which is why understanding the different dust classifications and correct extraction methods is paramount to safeguarding everyone's health and well-being, whilst remaining compliant with all legislative regulations.
The Different Dust Classifications
Low Risk (L-Class)
L-Class classification presents a moderate risk when inhaled, ingested, or absorbed through the skin and is commonly associated with softwoods and Corian. The exposure limit is >1mg/m³ and successful extraction is only achieved with a dust extractor that captures 99% of dust with a grain size of under two microns.
Medium Risk (M-Class)
M-Class classification presents a medium risk when inhaled, ingested, or absorbed through the skin. It's commonly associated with a wider range of materials including repair compound and wood dust, filler and clear coats, cement, concrete, and tile cement dust. The exposure limit is >0.1mg/m³ and successful extraction requires a dust extractor that captures 99% of dust with a grain size of under two microns.
High Risk (H-Class)
H-Class classification presents a high risk when inhaled, ingested, or absorbed through the skin. It's commonly associated with mould spores, asbestos, mineral fibres, bitumen, and artificial mineral fibres such as glass wool, and includes carcinogenic or pathogenic particles. The exposure limit is >0.1mg/m³ and successful extraction requires a dust extractor that captures 99.995% of dust with a grain size of under one micron.
Reasons Why Workplace Dust Extraction Is Paramount
Respiratory Concerns
Fine particles suspended in the air can be inhaled easily, resulting in respiratory tract irritation, coughing, and shortness of breath.
Skin Irritation
Dust exposure can cause skin irritation and allergies, notably for people with allergies to specific types of dust such as wood dust. Symptoms can range from mild itching to dermatitis.
Material and Mechanical Contamination
Very fine dust particles, especially those generated by industrial processes, can compromise the quality, safety, and integrity of products and raw materials. Because dust absorbs moisture, it is a breeding ground for mould and corrosion, leading to reduced product lifespan and increased repair costs.
Fire and Explosion Risks
Certain types of dust are fire hazards. Combustible wood, coal, and metal dusts can easily accumulate in workplace environments. If not extracted comprehensively, fire and explosions are a clear threat. Fine particles of combustible dust can become airborne during sanding, grinding, or cutting, and electrical sparks or heat can ignite them.
Permanent Damage to Respiratory Health
Prolonged exposure to airborne dust and particles, especially silica, can lead to severe respiratory health illnesses including COPD, lung cancer, and silicosis. Silica dust is commonly found in construction, mining, and manufacturing — concrete, stone, and brick all contain silica. When inhaled, these dust particles can cause irreversible lung damage.
Employer's Legal Responsibilities
Key legislation employers must be aware of includes: The Factories Act 1961, The Health and Safety at Work Act 1974, The Coal Mines (Respiratory Dust) Regulations 1975, and The Control of Substances Hazardous to Health Regulations 1988. Employers are legally responsible for maintaining a safe workplace for all employees.
How to Choose the Right Dust Extractor
- Level of filtration needed: L-Class, M-Class, and H-Class dust extractors feature ascending levels of dust extraction.
- Power source: Choose from 110v or 240v corded and cordless options. Mains powered dust extractors typically have greater power efficiency.
- Power take-off point: Allows operators to use a single plug socket for both the dust extractor and power tool.
- Auto on/off: Various M-Class and H-Class dust extractors connect to the power tool via Bluetooth and automatically run when the machine is in use.
- Capacity: V-TUF's range offers anywhere from 15L to 80L. Cordless dust extractors feature smaller capacity sizes to accommodate the battery.
- Wet or dry pickup: Some M-Class and H-Class dust extractors provide both wet and dry pickup, making them ideal for specific environments.
- Auto Clean: Many dust extractors feature an auto clean function with two filters operating in tandem - one cleaning the surface and one removing harmful substances.
