The Experience Modification Rate and the Total Recordable Incident Rate (TRIR) are both safety metrics.  They provide an objective measurement of an organization's safety performance.  However, there are many differences between the two.  EMR gives you a long-term perspective while a company's current TRIR is a reflection of the past year.  There are many more differences between both EMR and TRIR and you can use them for different purposes or in conjunction with one another.  For more information see our post on TRIR vs EMR.
