Why are exhaust fumes dangerous




















While diesel gases can seep into vehicle cabs when the windows are closed, this will limit contact with the particulate matter found in diesel exhaust. An appropriate nozzle is selected for your specific application. Hose is attached directly to the vehicle and easily modified for dual-exhaust. Hose is vented through or under the garage door with the assistance of a fan. Connects directly to the ducting system.

Hose is designed with the exact temperature and length needed for your custom application. Hose is stowed using an elbow joint which suspends the hose. A nozzle is selected which meets the needs of your custom application. The hose is lowered from the ceiling and easily unclipped for use. The nozzle 4 easily attaches to the exhaust source.

A drum stores the hose securely in place overhead. The hose reel is mounted to a steel beam. The hose reel lift system can be spring-operated or equipped with a motor. The hose reel exhaust port can be equipped with a direct mount blower or attached to a centralized ducting system.

The hose easily extends so that the nozzle can attach to the exhaust source. Boom arms can be mounted to a wall or braced to a beam, making them perfect for high ceilings or buildings with overhead cranes a problem for other systems. The boom arm swivels at the base, allowing it to tuck against the wall for out-of-the-way storage. A Pivoting-Articulating style optional , allows the arm to bend in the middle, providing for additional length and more compact storage. A Pivoting style standard , does not fold in the middle, but only allows pivoting at the base.

When the hose is not in use, or when the arm is stored, the hose can be lifted and stored. This allows for neat and compact storage when not in use. Thank You. The best way to treat CO poisoning is to breathe in pure oxygen.

This treatment increases oxygen levels in the blood and helps to remove CO from the blood. Your doctor will place an oxygen mask over your nose and mouth and ask you to inhale.

Your doctor may temporarily place you in a pressurized oxygen chamber also known as a hyperbaric oxygen chamber. The oxygen chamber has twice the pressure of normal air.

You should never treat CO poisoning yourself. If you believe you have CO poisoning, go outdoors immediately and call Researchers may have antidote for carbon monoxide poisoning ». Discover why gasoline exposure can be dangerous for your health. Learn about gasoline poisoning, carbon monoxide poisoning, when to seek help, and…. Some foods contain ingredients and chemicals that are harmful in large amounts.

Here are 7 food "toxins" that are actually concerning. Lead is a toxic metal and a very strong poison. Lead poisoning is serious and sometimes fatal. Studies have shown that many of these toxins have resulted in problems in the bloodstream such as anemia. Taking into consideration that carbon monoxide literally suffocates us it is no wonder that it deprives our bloodstream of oxygen necessary for so many vital functions within the body.

Some of these toxins, especially carbon monoxide, literally produce damage on a cellular level which can lead to a number of cancers.

Some of the other dangers of exhaust fumes include an exacerbation of heart disease due to hypertension and a degeneration of the cells which line blood vessels.

Many of these pollutants found in exhaust fumes of course cause respiratory problems as well including, but not limited to, asthma. There is also evidence to suggest that pollutants in exhaust fumes also cause irreparable damage to the central nervous system.

Combustion from fossil fuel engines such as those which burn gasoline and diesel fuel is causing irreparable damage to the environment. Carbon dioxide is also a problem and we know that it is the number one cause of the breakdown in the ozone layer which is leading to global warming. However, global warming is a catchall phrase that encompasses a great number of problems both to the earth on which we live and to the creatures that dwell on it.

Without going into a treatise on global warming it should be sufficient to say that the surface of the earth is heating gradually so that the polar ice caps are melting and growing seasons are being disrupted. Unfortunately, this is just the beginning of a snowball effect that filters down through virtually every life form on the planet.

Animal habitats are being destroyed at a record speed, which causes creatures to seek new sources of food and shelter.

Nick Molden is on the phone to talk me through it. First I must scroll horizontally across a document listing fuel efficiency, CO2 emissions, NOx and carbon monoxide emissions.

In fact Melvyn emits three times more NOx than the Skoda - 0. Nitrogen oxides are at their most dangerous in built-up areas where people breathe them in higher concentrations. But at 0. Melvyn's carbon monoxide value is high too. In urban driving it is 3.

But his overall figure of 2. The national average for Euro 6 post-autumn petrol cars is I'm relieved to say that neither car is breaking the law. But at the same time, neither would be allowed to be sold new today if these results were obtained in lab conditions.

The Skoda is about a third less than the current average. I ask him if I've understood correctly. My dad's car emits less NOx than most new diesels they've tested in the past three years? Yes, a third less, he says. So how come they are legal if the Skoda would not now pass the legal limit?

Here's the tricky bit. The limit on NOx for Euro 6 diesels is 0. My dad's Skoda comes in at 0. In other words, more than three times today's limit. But it is still better than most modern diesels. The new diesels pass the 0. Like a child coached to pass an exam they do well in controlled conditions.

But out in the real world they struggle. Having looked at the data for cars tested in and , I request the exact NOx figures for some of the more surprising scores. And what comes back is pretty shocking. But the worst is the Nissan Qashqai, which last month overtook the Ford Fiesta to become the UK's most registered car counting diesel and petrol models together. That is more than 18 times Europe's 0. The company said it had been gradually taking action to reduce the gap between the performance of its vehicles in the lab and on the road, for example by reprogramming their engine injection computer.

But how can it be that some new diesels are so dirty? Haven't they improved at all since my dad's car left the factory in ? Molden explains that there is a huge range.

While most petrol cars leave diesels far behind when it comes to NOx some new diesels are relatively clean and some are very dirty. Both cars produce less than a third of the amount of NOx that my dad's Skoda emits. But they are a rarity. So why are diesels managing to pass strict limits in the lab while producing high levels of emissions on the road?

This puts cars through a test involving steady acceleration, constant speed driving and steady deceleration. It bears no relation to how people actually drive, Bandivadekar says. Auto makers rather than trying to meet the spirit of the regulations are trying to meet the letter of the law. That's the crux of this. The technical reasons are multiple. There is one big disappointment about the Skoda's test results, I discover a couple of days later - it proved impossible to get an accurate measurement of the particulates emitted.

Molden is happy to say that Melvyn emitted a negligible quantity of particulates whereas the Skoda emitted more, but due to a technical problem I cannot publish the exact value. Belatedly, the authorities have woken up to the problem of misleading lab tests. But it is not retrospective, so all the millions of diesels labelled as compliant with the Euro 6 standard on the basis of a flawed lab test are still out there pumping out high levels of NOx. In addition, until carmakers will be given leeway of 2.

After that they will be given leeway of 1. This is partly because there is some variability in the results of the PEMS test. The new T Charge arrives next week in London. It will quite rightly penalise my Golf. But the next big change, the Ultra Low Emission Zone due to come into force in London in , will penalise Euro 4 cars and older.

Not according to Prof Frank Kelly, the man whose lecture helped change my dad's mind. Even electric vehicles produce particulates from wear on brake discs and tyres, and by throwing up dust on roads.

In any case it seems unlikely that petrol and diesel vehicles will vanish in the next five or 10 years. In which case there's a desperate need to sort the wheat from the chaff, the Tiguans from the Qashqais. When I phone my Dad to discuss the results, he's magnanimous in victory and agrees to accept a half rather than a pint because of the Skoda's higher particulates.

He says he is pleasantly surprised by the Skoda's NOx levels. But it's not enough. He worries about the particulates and the NOx in the city, so hopes to find a buyer who lives in a rural area. I wouldn't buy another diesel. I'm wondering about an electric car, but the problem is range.

So I'm tempted more by a hybrid. Eight days after the test I get a call from Beth saying that clouds of steam are billowing from his bonnet and she's been forced to park in a cul-de-sac 10 minutes from home. But we've made up our mind to have him scrapped. He is 13 times over the NOx limit for a new petrol car after all. It'll be sad to say goodbye.

He's only my second ever car. We've been to a lot of places together.
