Rapport om trafikkulykke med mobilkran ved Karussveien i Kristiansand 7. mars 2017
Road traffic report 2018/01
Statens havarikommisjon for transport (SHT) har undersøkt en ulykke med mobilkran som førte til at en 5 år gammel gutt omkom ved Karuss skole i Kristiansand den 7. mars 2017. Mobilkranen var midlertidig parkert før et arbeidsoppdrag da den skled/rullet bakover og ned en gangvei. Fire personer befant seg på gangveien, og disse ble påkjørt.
Ulykken skjedde i forbindelse med at mobilkranen skulle utføre et oppdrag på byggeplassen ved Karuss skole. Kranføreren rygget inn på en snødekket gangvei, satte på parkeringsbremsen og gikk ut av kranen. En kollega og kranfører skulle vurdere nødvendige sikkerhetstiltak, som bruk av kjetting.
Undersøkelsen har vist at parkbremsen på mobilkranen kun virket på framakselen, men ikke på den midtre akselen. De låste forhjulene var ikke tilstrekkelig til å holde mobilkranen i ro på den snødekkede veien, og den skled/rullet ukontrollert nedover.
Det er påvist at den sertifiserte sakkyndige kontrollen av mobilkranen som ble utført ca. to mnd. før ulykken ikke avdekket denne bremsefeilen. Kranfirmaet hadde heller ikke avdekket denne bremsesvikten. De mangelfulle bremsene, sammen med veiens helling og den lave friksjon på den snødekkede gangveien, førte til at mobilkranen skled/rullet ukontrollert ned bakken.
Undersøkelsen har påvist at sikkerheten var mangelfullt ivaretatt fra byggherres side, da Kristiansand kommune ikke kunne framlegge noen risikovurdering med tilhørende skiltplan for denne bruken av gangveien, slik regelverket krever. Den avvikende bruken av gangveien var derfor ikke skiltet eller regulert under byggeprosjektet, og det var kun en følgemann som skulle ivareta sikkerheten for de som benyttet gangveien.
Havarikommisjonen har avgitt tre sikkerhetstilrådinger i denne undersøkelsen.
Safety recommendation
Safety recommendation ROAD No 2018/01T
The accident outside Karuss Kindergarten and School in Kristiansand on 7 March 2017 occurred on a pedestrian walkway, at a time when children and families were on their way to school/ kindergarten. A child died in the accident. The walkway was being used as an access route to the building site during the renovation of a primary school. The investigation has shown that Kristiansand Municipality, being the client, failed to identify the need to include a work notification plan in the health, safety and working environment (HSE) plan for the project. The AIBN believes that a work notification plan and related risk assessments would have been capable of identifying potential conflicts between vehicles and pedestrians/cyclists, and ensuring the posting of appropriate signs and proper adaptation of the access route.
The Accident Investigation Board Norway recommends that Kristiansand Municipality implement procedures to ensure road safety by requiring that work notification plans be prepared in connection with municipal building works that affect public roads.
Safety recommendation ROAD No 2018/02T
The accident outside Karuss kindergarten and school in Kristiansand on 7 March 2017 claimed the life of a child who became trapped under a mobile crane with inadequate braking power. The official inspection of the mobile crane had not been able to identify these defects. The mobile crane was initially registered in 2006 and was thus exempt from the Road Traffic Act's requirement for periodic roadworthiness tests. Pursuant to Section 13-1 of the Regulations on the Execution of Work, mobile cranes and other work equipment are subject to a requirement for certified inspection by an enterprise of competence. The AIBN's investigation has shown that the inspection regime does not include unambiguous guidelines for the inspection of brakes and other technical driving equipment.
The Accident Investigation Board Norway recommends that the Norwegian Labour Inspection Authority, in its capacity as supervisory body, ensures that inspections by enterprises of competence of brake systems on mobile cranes and other plant and machinery not subject to periodic roadworthiness tests are carried out in a uniform manner and so as to ensure an adequate level of road safety.
Safety recommendation ROAD No 2018/03T
The accident outside Karuss kindergarten and school in Kristiansand on 7 March 2017 claimed the life of a child who became trapped under a mobile crane with inadequate braking power. The official inspection of the mobile crane had not been capable of identifying these defects. Mobile cranes that were registered before 15 September 2012 are exempt from the requirement for periodic roadworthiness tests, and the certified inspections by enterprises of competence are not subject to uniform guidelines for inspection of brake systems.
The Accident Investigation Board Norway recommends that the Norwegian Public Roads Administration initiate measures to ensure that all registered mobile cranes, plant and machinery used on roads are subject to uniform brake system inspections.
