Introduction: Brick manufacturing industry is an old and important industry in Egypt. It involves three main steps: clay shaping with water (molding), drying with solar energy and firing with fuel (baking). Aim of work: To study the respiratory health problems among workers engaged in brick kiln industry. Materials and Methods: a comparative cross sectional study was conducted among 173 male brick kilns workers in Mit Ghamr District, Dakhlia Governorate. A control group of 170 seller men matched with the exposed brick kilns workers were included for comparison. After dust sampling in the brick kiln factories, the included persons were subjected to: 1-a modified pre-constructed questionnaire inquiring about: socio-demographic data, detailed occupational history, present history of acute and chronic respiratory symptoms and relevant past and smoking history 2-pulmonary function test 3-Environmental assessment of the working place. Results: measured mean dust concentration from 10 factories was 31.2 mg/m 3 exceeding the permitted level in the Egyptian work law 2003 (10mg/m 3). This study showed that brick kilns workers had significant higher frequency of chronic respiratory problems compared to their control group and the most common chronic respiratory symptoms among them were chronic cough followed by dyspnea, chest wheeze chronic bronchitis, and asthma. Moreover, 39.91% of brick kilns workers were complaining of more than one respiratory symptom compared to 11.70% among
