More About Our Vehicle Exhaust Extraction Products
By installing an exhaust fume extraction system, you will be providing a pollution-free environment for staff, leading to better health and reducing the number of sick days taken.
How Can Exhaust Fumes Harm Your Health?
Engines, whether they are in cars, buses, trucks or locomotives, produce exhaust from the combustion of fuel. This exhaust fume is a mixture of organic and inorganic constituents (products of incomplete combustion). In simple terms, the exhaust is a mixture of gases and carbon-core particles that have a coating of various inorganic/organic compounds (POM/PAH). Diesel engines produce 20 to 100 times more particles than petrol engines.
Emissions include over 40 substances that are listed as hazardous air pollutants and 15 of them are listed as carcinogenic to humans.
Exhaust can either appear as grey or black smoke or maybe invisible. People can see particles down to 20 microns. Ninety percent of exhaust particles are smaller than 1 micron. In comparison, a strand of human hair is 70 microns thick. This sometimes misleads people. Many believe that if they don't see the exhaust, that there is no danger to their health. The new generation of "clean" diesel engines with their invisible emissions have contributed to this problem.
New-generation diesel engines produce 15 to 35 times more small particles than old-generation diesel engines.
The difference between the old and the new generation of engines is in the size of the particles. New-generation diesel engines produce more ultra-fine particles, invisible to the naked eye, and it's because of this, it seems that the dangers have disappeared, but this is far from the truth...
How are People Exposed to Emissions?
People, typically employees are exposed to emissions when working in confined spaces in which engines are running.
Occupations with potential exposure to emissions include:
- Truck drivers
- Mine workers
- Vehicle maintenance workers
- Loading-dock workers
- Tunnel workers
- Material-handling machine workers
The particles remain airborne for a long time and this problem became larger with the ultrafine particles produced by new-generation engines. Ultra-fine particles are more easily transported by air currents and penetrate deeper into our lungs.
Because of this, not only are the people who are in the same confined spaces as running engines exposed to the harmful emissions but as a result of ineffective ventilation, people (such as office workers) working in adjacent spaces are also exposed to the dangers of the airborne particles.
Health Effects from Exhaust Fumes
We inhale airborne particles without even thinking about it. This is how the particles enter our respiratory system and fasten in our lungs. This can affect human health in both the short and the long term.
The problem with the particles is that they remain in our lungs. This is in contrast to the gases we inhale. Gases are transported to our blood vessels. In the worse case, this can cause blood poisoning. The difference between the lungs and blood is that blood regenerates itself and there is no permanent damage. With the lungs, this is not the case. Every time we inhale particles, more particles accumulate in our lungs and they are there to stay.

We Have the Right Exhaust Fume Extraction Solution for Your Business...
Above all, it is important is to deal with the problem at the source. Using a roof-mounted ventilation system for a confined space is most often useless because people working in the space still inhale the polluted air.
The most economical solution is a vehicle exhaust fume extraction system. But in many cases, such a system is either impossible or impractical to use. Examples of such cases might be when you need to move vehicles in confined spaces or when it's logistically and/or economically impossible to use an extraction system.
What Do The HSE Recommend?
The HSE state: “Exhaust fumes can irritate the eyes and respiratory system and are a risk to health by breathing in. Carbon-fuelled engine fumes contain carbon monoxide, a poisonous gas. Prolonged exposure to diesel fumes, especially blue or black smoke, may lead to coughing and breathlessness. Long-term repeated exposure to diesel fumes over a period of time may increase the risk of lung cancer.”
The HSE also advises: “Keep the workplace well ventilated. Connect an exhaust gas scavenger system to the tailpipe when static running, particularly when working in an inspection pit. It should ventilate to a safe place in the open air — where fume will not be drawn back into the workshop or affect other premises or people nearby. Maintain couplings and flexible connections in good condition to prevent leaks. You should not rely on access doors being left open to provide ventilation as in winter these will be kept closed.”
