Measurement of Occupational Health and Safety Performance, KPI & OHS formulas

 

Measurement of Occupational Health and Safety performance is key to OHS success. With the measurement of Occupational Health and Safety performance organization got a clear picture of where the organization stands to achieve Occupational Health and Safety objective and target.

 

Occupational Health and Safety performance always measure against the objective and target set in the Occupational Health and Safety policy. With the measurement of performance organization management aware of the improvements if needed. If improvement needs senior management to intervene to achieve the set objectives and targets. With the senior management's positive intervention always performance in Occupational Health and Safety improved.

 

Occupational Health and Safety highly relied on senior management commitment, As the Occupational Health and Safety roles and responsibilities or commitment travel top to bottom does not bottom to the top. So senior management commitments and interventions always matter for the Occupational Health and Safety performance.

 

For the measurement of Occupational Health and Safety organization Occupational Health and Safety department has a key role.  Occupational Health and Safety department set the KPI (key performance indicator) against each objective and target & KPI reports must be submitted to senior management every month so management can intervene in timely manners.

 

KPI (Key performance indicators) must be SMART ( specific, Measurable, Achievable, Realistic & timebound )  Occupational Health and Safety team always keep in mind these five Keyes during setting the KPI. KPI  must be set against each objective and target. From the KPI report, organization management checks the leading and lagging trend and act accordingly.

 

Leading indicators always show your achievement like Safe man-hours, safe kilometers, safe days, etc., and the lagging indicator shows need improvements, like first aid, Recordable, MTC, LTI, fatality, etc.

 

If KPI shows leading indicators management need to make s strategy to maintain the level so the leading indicator does not convert to lagging.

If lagging indicator shows mean need senior management intervention with immediate effect, Management needs to look in employee competency, resources, training, supervision, BBS program, etc.

 

HSE department is responsible to set KPI, monitor the KPI, and report KPI trends to senior management in a timely manner.

 

For measuring Leading  &  lagging indicator frequency followings formula can be used.

 

Lost Time Incident  (LTI)	Injury or illness which results in a day lost after the day of the incident
Lost Time Incidence Frequency (LTIF)	(Total Number of LTI plus Fatalities / Total Man hours worked) x 1,000,000
Severity Rate (SA)	(Total days lost/ Total Man hours worked) x 1,000,000
Restricted workday Case (RWC)	Employee not capable of fulfilling all roles/responsibilities due to injury/illness but is available for work after  the day of the incident.
Total Recordable Incidents (TRI)	(No. of Fatalities) +(No. of LTI's)+( No. of RWC) + (No. of MTC)
Total Recordable Case Frequency (TRCF)	(Total Recordable Incidents / Total Man hours worked) x 1,000,000
Total Recordable Incidence Rate (TRIR)	(Total Recordable Incident / Total Man hours worked) x 200,000
Total Recordable Occupational Illness Frequency  (TROIF)	(Total Number of Occupational Illness / Total Man hours worked) x 1,000,000
Road Traffic Accident Frequency (RTAF)	(RTA,s*1,000,000/Total Kilometers Driven)
