  Background: The need for high-quality education and setting principles and practices for enhancing educational policy and practice using modern techniques is self-evident. The entrance of students into the factories is sometimes limited, and of particular concern is that students likely face danger by their presence at the workplace. A review of the related literature revealed no research involving simulations of airborne particles in the occupational health labs in our country. The aim of this study was to design a producer and simulator of airborne pollutants for measuring gases, vapors and particles in the lab.

  Method: First, a comprehensive search was performed through different and present modern laboratory systems for generation and collection of dust. Then, interviews were carried out with stakeholders researchers lecturers our colleagues and students. Later, the laboratory chamber for simulation was designed and assembled.

  Results: This paper describes laboratory chamber for simulation. It is possible to suspend dust, vapors and gases inside the chamber for measurement. The assessment of dispersed dusts inside the chamber showed relative steady concentration of respirable dust the average of which was 24.3 mg/m3 after 20 minutes.

  Conclusion: Satisfaction of occupational health students about good performance of chamber for teaching of sampling method indicates that this chamber can be used in all occupational labs for enhancing education quality without taking students to the field .
