CERN has a variety of rules regarding the reporting and follow-up of incidents, including accidents and near misses.
Pushed by both the management and external authorities CERNs HSE unit has recently conducted a critical review of its current incident management system and is in the now working on a new set of more consistent rules and procedures as well as the related processes and tools....

When designing a complex facility, project decision makers must cope with the problem of choosing among multiple fire protection packages and emergency response service models to guarantee the compliance to the safety goals and objectives. Passive and active fire protection measures can be costly thus requiring a thorough and solid justification.

Internal arcing faults in oil insulated electrical components can lead to a severe accident scenario escalation. When dielectric breakdown occurs in this kind of component, the consequent electric arc decomposes the surrounding oil into a saturated gaseous hydrocarbon mixture by means of a pyrolysis reaction, leading to a sudden pressure build-up into the component enclosure. For severe...

At CERN, many different types of installations, such as small laboratories, experimental halls and accelerator tunnels, require the use of cryogenic liquids and gases, typically stored in cylinders, gas tanks, or Dewar vessels. Since a liquid cryogen can expand, the uncontrolled release into an enclosed space can easily cause an Oxygen Deficiency Hazard (ODH). In this paper a methodological...
