  Background & Objectives: Educational and research laboratories in universities have a high risk of fire, because they have a variety of materials and equipment. The aim of this study was to provide a technical plan for safety improvement in educational and research laboratories of a university based on the design of automatic detection, alarm, and extinguishing systems .

  Methods : In this study, fire risk assessment was performed based on the standard of Military Risk Assessment method (MIL-STD-882). For all laboratories, detection and fire alarm systems and optimal fixed fire extinguishing systems were designed.

  Results : Maximum and minimum risks of fire were in chemical water and wastewater (81.2%) and physical agents (62.5%) laboratories, respectively. For studied laboratories, we designed fire detection systems based on heat and smoke detectors. Also in these places, fire-extinguishing systems based on CO2 were designed .

  Conclusion : Due to high risk of fire in studied laboratories, the best control method for fire prevention and protection based on special features of these laboratories is using automatic detection, warning and fire extinguishing systems using CO2 .
