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

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
 Immediately inform the CERN Fire Brigade or

Internal Accident Report (EDH – Code A2)
Electronic form for application of the Code A2 – Internal Accident Report – available for all persons with a CERN account
Implementation of the safety code A2
Call-out reports (Fire and Rescue & Medical Services)

5. 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

7. 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

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

10. Follow-up / Lessons learned from accidents & near-misses at CERN
Figure 1 : Main causes of absence from work – e.g. falls = 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) 
