The laboratory is a place to simulate actual conditions equipped with equipment. All equipment has potential hazards: mechanical, electrical, chemical, physical, biological and ergonomic. This study aims to determine the potential risks, assess the risks' level, and then provide solutions for each hazard found. The method used in this research is HIRA and HAZOP. The results obtained in this study are that three laboratories have several extreme risk values, five laboratories have a highrisk value. Then five laboratories with medium category and eight laboratories with low class.
