Note: Some data may be excluded from GOS under a contractual Force Majeure with Telnet, covering exceptional events.
OUR TARGET Our aim is a 75 percent success rate for RY20, RY21 and 80 percent for the remainder of the planning period from RY22 to RY28. 2.3 SAFETY Our focus on Safety is to design assets and work practices that prioritise the elimination of hazards and harm for workers, customers and the public in the delivery of electricity services. DEFINITION The total recordable injury frequency rate (TRIFR) encompasses all network incidents resulting in a medical treatment, restricted work injury, lost time injury or fatality, which impacts Vector people including all contractors and FSPs. MEASUREMENT The incident count is divided by the number of hours worked for the same measurement timeframe, Vector reports TRIFR as a moving 12-month value which is then normalised to report TRIFR in per million hours worked. HISTORICAL PERFORMANCE Table 2-6 shows the Networks TRIFR performance in accordance with the definition of this service level metric. Over the last two years we have created a change in focus to enhance reporting and drive improved wellness which has caused an increase in this calculated rate. Increasingly, focus is being given to underlying issues and treatment with more targeted at critical risk events. This movement in the rate is a temporary situation with the RY19 showing the expected decrease. 2.3.1 TOTAL RECORDABLE INJURY FREQUENCY RATE SERVICE LEVEL

TARGET The Networks TFIFR target for RY19 is 9.58. Future years targets are yet to be confirmed but it is likely a 5% movement band will be introduced rather than a reduction only target.
2.3.2 ASSET SAFETY INCIDENT SERVICE LEVEL
DEFINITION The asset safety incident measure is a count of incidents that resulted in harm to personnel, members of the public or to property, resulting from a deficiency or failure in any equipment on Vector’s electricity distribution network. MEASUREMENT The asset safety incident measure is calculated by identifying the number of asset safety incidents in Vector’s Risk and Incident Management System (RIMS) which have caused harm or damage to people or property.
HISTORICAL PERFORMANCE Table 2-7 shows the asset safety incident performance in accordance with the definition of this service level metric.

Table 2-6 Asset Safety Incidents
The increase in the number of asset safety incidents was unusually high in RY18. Out of the seven incidents, two involved animals coming in contact with lines down, three were related to loose neutral connections and minor electric shock and
