Lessons Learned From Major Events Towards Improving Hydraulic Safety

Lessons learned from major events towards improving hydraulic safety

Study
-
Since 2010, information collected on dam-related events has been recorded in the ARIA base. By the end of 2015, a total of 228 events had been entered into the database. This summary, written jointly by the BARPI and BETCGB bureau, presents the primary lessons resulting from their analysis. The study method has focused in particular on experience feedback regarding hydro-mechanical devices and command-control systems

Power Outages During Periods Of Cold Weather

Power outages during periods of cold weather

Flash
-
Periods of cold weather are characterised by low temperatures, sometimes combined with snowfall and/or wind. Synonymous with high electricity consumption, they are often the cause of power failures and other critical systems, such as telecommunication networks, can also be affected. If energy demand is higher than production, load sharing can be implemented. But what are the risks?

The End Of The Switched Telephone Network

The end of the switched telephone network

Flash
-
In an emergency situation and primarily in the event of a power outage, only switched telephone networks (PSTN) are operational. The traditional French operator’s plan to abandon these networks in 5 years time in favour of VoIP solutions should be anticipated.

Anticipating Fire And Explosion Risks In Wood Silos

Anticipating fire and explosion risks in wood silos

Flash
-
Over the past 3 years, more than 40 fires involving silos containing wood chips or sawdust have been recorded in the ARIA database. In such instances, operational difficulties are commonly encountered by emergency services (lengthy interventions, vulnerability of storage structures, etc.). Each response is therefore unique and requires comprehensive knowledge of all potential risks.

Hydrofluoric Acid : The Worst Of All Acids?

Hydrofluoric acid : the worst of all acids?

Flash
-
Despite being produced 200 times less than sulphuric acid (1 M vs. 200 M tonnes/year), the ARIA database has recorded nearly 80 accidents involving hydrofluoric acid (HF) (vs. 220 for H2SO4). A series of recent accidents serves to recall its hazards, especially the serious consequences in the event of its release...

Cooling Towers: Legionnaire’s Disease Still Running Rampant!

Cooling towers: Legionnaire’s Disease still running rampant!

Flash
-
The group outbreak of Legionnaire's Disease in the Lisbon suburbs in 2014 has provided a sad reminder: the propagation of legionellae within the water circuits of cooling towers is a likely scenario and one capable of causing major health impacts whenever water droplets are dispersed from these towers. The regulatory regime for preventing the risk of legionellae stemming from cooling towers has been substantially modified. The regulations currently in effect in France are considered by experts to be among the most elaborate. Nonetheless, new cas [...]

Automatisms accidentology

Study
-
As the second chapter of an accident analysis devoted to industrial automation within the ARIA base, this study presentes the main lessons drawn from a detailed analysis of 325 accidents of remote operated plant found in the base. These lessons and recommendations are intended to build awareness among safety professionals working at industrial facilities.

Bases For An Accident Study On The Inerting Process Practiced In Silos

Bases for an accident study on the inerting process practiced in silos

Study
-
The use of an inerting process is a means of intervention used in a fire in grain silos. However, it remains uncommon. As part of its work, the BARPI wrote a synthesis on this process based on the accidents contained in the ARIA database. This synthesis addresses the following issues : What are the conditions of use of these devices and what are the difficulties experienced by those that are involved in the implementation of these devices?
