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 [...]

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?

Accident Study Findings On Malicious Acts Perpetrated In Industrial Facilities

Accident study findings on malicious acts perpetrated in industrial facilities

Study
-
Beyond criminal acts targeting “Seveso” installations and having a strong media impact, the fight against "ordinary malicious acts" is a stake for all operators! Indeed, 4% of accidents occurring in Classified Facilities are related to malicious acts. This accident cause, often overlooked in risk analyses and safety reports, therefore deserves to be dealt with. This synthesis report is based on an analysis of 850 accidents involving malicious acts.

Analysis Of Pressure Equipments Related Accidents

Analysis of pressure equipments related accidents

Study
-
Pressure equipments are everywhere in our daily life: fire extinguishers, LPG tanks, compressors, oxygen bottles are just examples. The knowledge of their potential danger, both in operating or in maintenance phase, can limit the consequences of accidents. This study based on 247 French events extracted from the ARIA database, paints a portrait of pressure equipments related accidents.
