ABSTRACT
Ergonomics studies the criteria needed to adapt the environment and products to human characteristics. In order to do this, it applies theories, principles, data and methods that can previously preserve human life in aspects related to health, safety, comfort and satisfaction. The ballistic vest, being a protective equipment that is next to the body of the user, causes a great majority of police officers to feel a lot of discomfort, causing worsening of low back pain, since the lumbar segment already suffers constantly with the weight that supports, both of the upper segments of the column and of gravity itself. In this context, understanding that ballistic protection equipment does not present any criteria for the comfort of the policeman, the present work aims to analyze ergonomic aspects of the Baltic vests, seeking to understand the user-vest relationship.
