Pharmaceutical industry is one of the most rising industries in Bangladesh where various types of medicines are administrated to people with a view to curing them. Many workers as well as top and middle management are responsible to run the industry successfully. But because of not taking proper precautions, different failure causes result in various failure modes in each section of the industry that may affect the safety issue of the workers and effectiveness of the industry. In this research work, failure caused and failure modes were determined through performing a survey. Risk priority number method was evaluated for each failure modes caused by subsequent reasons of failures by learning the severity, detection and occurrence of each failure form. The higher risk priority number resulted in the greater criticality caused by failure modes. Proper preventive methods were encouraged to carry out to mitigate the criticality and to ensure proper working environment for all the workers involved in the pharmaceutical industry.
