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.
