In the healthcare sector (incl. nursing homes and hospitals), there are employees, patients and visitors who smoke. Patients (and particularly psychiatric patients) in nursing and care homes smoke much more than other groups. In some cases the patient has already been through a lot or had to make great sacrifices, so it would be heartless to deny them one of their last remaining comforts. Smoking is often permitted in the healthcare sector. A good provision for extracting the tobacco smoke is therefore necessary to keep the nuisance for personnel and visitors to a minimum. They must not be affected by the tobacco odour or tobacco smoke present in the smoking room that could ‘leak’ out. Therefore it must be sealed effectively and equipped with adequate smoke extraction.
