REPORTING & FOLLOW-UP OF ACCIDENTS & NEAR-MISSES AT CERN Presented by Carine Pividori HSE/SEE Accident/incident prevention & follow-up service 16/03/2017

Reporting of accidents & near-misses at CERN For © cf. http://www.seahealth.dk 1 10 30 600 Serious or Major Injury Minor Injury Property Damage Accident Near-miss This triangle is coming form M. Bird’s studies. He was working for an Insurance company and in the 60s he analysed more than 1.5 millions accidents reported to the company and put in evidence that there is a direct relation between serious accidents and near misses with a ratio 1 on 600. Illustration with a lifting operation. In the picture we can see «lucky workers» as the load is falling just in front of them. Most of the time, this kind of accident will not be reported & no analyse will be conduct. But in the case where the workers would have been under the load... By analysing the event we will show that, for different consequences the causes are the same. Near-misses are warnings Actions must be taken at this level 16/03/2017

Reporting of accidents & near-misses at CERN Safety Code A2 “Reporting of Accidents and Near Misses “  Any accidental event which has or might have caused personal injury and/or damage to property or the environment shall be reported https://edms.cern.ch/ui/file/335502/LAST_RELEASED/E_A2.pdf  Immediately inform the CERN Fire Brigade 7 4444 or +41 22 767 4444 16/03/2017

Reporting of accidents & near-misses at CERN Compilation by HSE Unit of the events in a spreadsheet Distributed: weekly within Departments & Large Experiments (DSOs/LEXGLIMOSes) for action monthly to TSOs for information 16/03/2017

Analysis of accidents & near-misses at CERN The HSE Unit on call accident service The factsheets produced by the HSE Unit Carine Pividori Laetitia Wohlgemuth Dorine Fallavier François Angerand Thibaut Gilles Valentin Algoet Laure Tranchand Pauline Lonjon Renaud Mouret 16/03/2017

Analysis of accidents & near-misses at CERN The analysis of an accident is the responsibility of the DSO in the Departments or the LEXGLIMOS in large Experiments 3 type of accidents must be analysed as a minimum : - accidents resulting in falls - accidents that led to days of absence from work - accidents linked to the use of a vehicle on CERN roads The DSO or LEXGLIMOS defines if an analysis is required or not regarding : • the potential severity of the event (impact on the health, in the environment, in the installations and in the equipments), • the number of corrective and preventive actions which can be identified Evénements à analyser : principales causes d’absentéisme au CERN, i.e., accidents de chutes + accidents du travail avec arrêt + accidents liés à l’usage d’un véhicule motorisé ou non sur les sites du CERN Autres analyses à la demande de l’Unité HSE ou sur initiative des DSOs/LEXGLIMOS Other analyses can be requested by HSE Unit and/or are left to the initiative of the Departments 16/03/2017

Analysis of accidents & near-misses at CERN Accident analysis report Established by the DSO or LEXGLIMOS concerned They define, with the people in charge of the implementation of the actions, the action plan to be followed Evénements à analyser : principales causes d’absentéisme au CERN, i.e., accidents de chutes + accidents du travail avec arrêt + accidents liés à l’usage d’un véhicule motorisé ou non sur les sites du CERN Autres analyses à la demande de l’Unité HSE ou sur initiative des DSOs/LEXGLIMOS 16/03/2017

Follow-up / Lessons learned from accidents & near-misses at CERN Figure 1 : Main causes of absence from work – e.g. falls 45+20 = 65% of the total days off registered in 2015 Figure 2 : Kind of calculation made for comparison with others HEP Laboratories Figures 3 : Indicators frequency & severity rates – comparison with those provided by our contractors Figure 4 : Type of events reported by an A2, increase of knowledge of near misses… source of improvement (cf. slide 1)  16/03/2017
