Development of a novel second-hand smoke reduction device

الملخص EN

Smoking remains a worldwide health hazard.

Smokers don't only put themselves at risk of serious health problems, but people around them are also exposed to such potential danger.

This passive exposition is called: Second Hand Smoke (SHS).

To limit the SHS contamination in an Environmental Tobacco Smoke a new “Healthy Second Hand Smoke (HSHS)” device was developed.

In this paper, we will explain the functioning basics of the HSHS device.

It is mainly based on an insulated smoke compartment with transparent view, placed in the area where smokers and non-smokers exist together.

Smoker inhales and exhales smoke through an “HSHS” accessory called “hand” which is related to the compartment by two hoses.

In this compartment, an aspiration system is used to evacuate the smoke.

The efficiency of the “HSHS” device is then evaluated.

For four hookah smokers, the Carbone monoxide gas concentration was measured during 30 min in a 5.3 m3 unventilated experimental room.

A comparison was made between the smoke concentration in the unventilated room, with and without the use of the HSHS device.

Statistical tests were performed in order to insure the validity of the results that were taken for four smokers only.

The results show that the use of HSHS device reduces second hand hookah inhalation smoke, in a 5.3 m3 unventilated room, by 95.9 % ± 28.2 %, 91.8 % ± 37.5 %, 97.8 % ± 15.7 % and 98.5 % ± 66.2 % during 10, 15, 20 and 25 minutes respectively.

As a conclusion, this new smoking concept opens the way for less invasive smoking habits in crowded environments.
