Background:Worldwide more than three billion people continue to depend on solid fuels, including biomass fuels (wood, dung, agricultural residues) and coal, for their energy needs. Cooking and heating with solid fuels on open fires and/or traditional stoves may result in high levels of health–damaging pollutants (including particulates and carbon monoxide).  The use of traditional stoves in poorly ventilated houses may cause particulate pollution. According to the World Health Report 2002, indoor air pollution (IAP) is responsible for 3.9% of the global burden of diseases such as chronic bronchitis, pulmonary disease and lung cancer.Objectives: To assess pre interventional knowledge regarding smokeless chulah among people of slums. To assess the effectiveness of awareness programme. Materials and Methods:pre–experimental design was conducted on 60 villagers in Mohal Nagar who were using traditional chulah to cook food.In pre–test knowledge levelof villagers regarding smokeless chulah was assessed with the help of set of questionnaire. On 7th day after awareness programme post–test was conducted using the same tool.Result:Paired t–test used andwas found to be 3.82 with 59 degrees of freedom at this 0.05 level which is more than the table value and also the corresponding p–value was small (less than 0.05),hence the null hypothesis is rejected. Awareness programme was effective among the villagers. Conclusion:In this studywe got to know that the knowledge of villagers was very poor regarding smokeless chulah. They were still using traditional chulah to cook food which may result in one or the other health problems.After providing awareness programme in the form of a role play, their knowledge level regarding smokeless chulah increases as compared to the previous reviews.
