<blockquote>''We are proud, but we are under no illusions as we move into the pre-implementation phase of going smoke-free. The journey doesn’t stop here. In many ways this is just the beginning. There is already talk of legal action from sectors of the hospitality industry, and we know from experiences in other countries that we will face further opposition in various shapes, forms and guises. There are many tobacco industry battles to come, in Scotland, in the UK and internationally. Our tale of victory isn’t sufficient in itself to force the tobacco industry to concede.''</blockquote>

This raises quite a number of questions.  The expected “many tobacco industry battles to come” justify delaying research and development of essentially life saving technologies, such as ventilation/air cleaning.

Declaring that “there was no safe level” for second hand smoke and concluding that nothing other than an indoor tornado would be effective and therefore only a smoking ban would ensure this illusive “safety” air filtration research<ref>http://www.repace.com/pdf/iaqashrae.pdf</ref>  and development has been and is being seriously compromised.

In a hospital environment when it comes to eliminating hospital acquired infections, such as MRSA (methicillin resistent staphylococcus aureus), air filtration is a vital tool.  Would this development and deployment of air filtration in hospital environments not have come much sooner if it wasn't for ASH's negativity?

Furthermore, the benefit of air filtration outside the hospital environment is becoming a possibility in controlling other potentially lethal viral infections. (http://www.iqair.com/uk/newsroom/2009/05/airborne-infection-control-of-swine-flu-virus/)

It is a well known fact that micro-organisms adapt at an alarming rate; bacteria become resistant to antibiotics and relatively harmless viruses show mutations changing them into something deadly.

''“The air pollutant sources in kitchens and bakeries are well known to the BGN (Berufsgenossenschaft Nahrungsmittel und Gastgewerbe), as we have spent a long time dealing intensively with them. Ventilation and air conditioning has been also an issue for the BGN for a long time, long before technical solutions for non-smoker protection became an issue of interest.

Conventional ventilation and air condition installations in kitchens usually transport the hazardous materials right past the airways of the chefs before they are being passed into the air. Therefore our experimental and research work concentrated on developing a ventilation type and making it operational, with which this can be avoided.

The results of our research were installations, which are based on the principle of layer ventilation. Such systems are naturally not only suited to eliminate the carcinogens produced during cooking and baking, but the principle is also applicable for use in smoking areas. Tests with such equipment installed in catering businesses have already taken place and in our opinion the results were convincing''.</blockquote>

If nothing other than zero exposure ensures health, not even “proper ventilation” can. Would the provision of acceptable air quality, thus “Zero Exposure”,  in coal mines require the equivalent of an “in mine tornado”?

High levels of methane and other airborne contaminants in underground workings are often most easily controlled through dilution with increased ventilation airflow.
