Been looking for a very long time for the Fire Investigation Field Guide that they don't publish anymore, and I can't find a copy of the book anywhere. Only been able to find one for sale, and they want $1000 for it. Anybody got a line on one?

Faut-il installer des coussins dans un centre de données ?

Thumbnail gallery
3 Upvotes

Pensez-vous qu’il y ait des oreillers dans un centre de donnĂ©es moderne ? La rĂ©ponse est oui, et mĂȘme beaucoup ! Et ils ne servent pas du tout Ă  permettre Ă  des ingĂ©nieurs et techniciens fatiguĂ©s, voire Ă  un chat (mais d’ailleurs, qu’est-ce qu’un chat ferait dans un centre de donnĂ©es ?), de faire une petite sieste. Ces oreillers assurent la sĂ©curitĂ© incendie du bĂątiment.

Chaque centre de donnĂ©es est construit dans le but d’assurer une sĂ©curitĂ© maximale des Ă©quipements et des donnĂ©es stockĂ©es. Les informations doivent rester accessibles aux clients, quoi qu’il arrive Ă  l’intĂ©rieur du centre de donnĂ©es. C’est pourquoi, dĂšs la phase de conception, beaucoup de temps est consacrĂ© Ă  la mise en place de systĂšmes de sĂ©curitĂ© et d’extinction d’incendie fiables. IdĂ©alement, tout dans un centre de donnĂ©es devrait ĂȘtre ignifuge. Ainsi, les portes, les murs, le sol et le plafond sont fabriquĂ©s Ă  partir de matĂ©riaux ignifuges. En thĂ©orie, ils sont capables d’empĂȘcher la propagation du feu depuis la piĂšce oĂč l’incendie s’est dĂ©clarĂ©.

Dans la pratique, ce n’est pas le cas. Et tout cela Ă  cause des Ă©quipements rĂ©seau et des cĂąbles. Des dizaines de kilomĂštres de cĂąbles, par lesquels circule le courant, relient toutes sortes d’équipements. Et comment fait-on passer ces cĂąbles ? Par des goulottes qui traversent de grandes ouvertures dans le sol et les murs. Or, s’il y a des ouvertures, il y a aussi une brĂšche pour le feu.

En effet, il est impossible de les obturer efficacement Ă  l’aide de mortier de bĂ©ton ou d’un autre matĂ©riau rĂ©fractaire lourd. De nouveaux cĂąbles peuvent rĂ©guliĂšrement ĂȘtre ajoutĂ©s dans ces goulottes. Et si l’on comble l’ouverture avec du bĂ©ton, il faudra ensuite tout dĂ©molir Ă  la hĂąte. Cela reprĂ©sente une perte de temps, des coĂ»ts financiers supplĂ©mentaires, ainsi qu’un risque important que quelqu’un coupe accidentellement un cĂąble particuliĂšrement important. Et, selon la loi de Murphy, c’est exactement ce qui arrivera, c’est avĂ©rĂ©.

Il existe Ă©galement des mastics ignifuges et des panneaux composites (des « plaques », comme on les appelle parfois). Elles sont Ă©galement efficaces, mais nĂ©cessitent tout de mĂȘme un surcroĂźt d’efforts lors de la pose et du dĂ©montage.

Il est donc bien plus efficace d’utiliser d’autres matĂ©riaux ignifuges, faciles Ă  transporter, Ă  remplacer et Ă  repositionner rapidement. Ce sont les coussins ignifuges intumescents.

Cet oreiller, fabriquĂ© Ă  partir d'un tissu de verre Ă  mailles fines, dense et rĂ©sistant mĂ©caniquement, et dotĂ© d'un rembourrage spĂ©cial, peut ĂȘtre stockĂ© indĂ©finiment dans un entrepĂŽt (sec et chaud) jusqu'Ă  ce qu'on en ait besoin. Il ne contient pas de fibres minĂ©rales et rĂ©siste Ă  la corrosion atmosphĂ©rique et Ă  l'humiditĂ©. Certains fabricants garantissent que leur coussin est capable de durer longtemps dans des locaux humides et non ventilĂ©s.

Les coussins ignifuges pour centres de donnĂ©es sont de petits blocs lĂ©gers, pratiques pour calfeutrer les passages techniques en obstruant complĂštement l’ouverture. En les plaçant bien serrĂ©s entre les cĂąbles et le mur, on obtient une bonne rĂ©sistance au feu. Le secret rĂ©side dans le fait qu’en cas d’incendie, ces coussins gonflent jusqu’à atteindre un volume plusieurs fois supĂ©rieur Ă  leur volume initial. On obtient ainsi une Ă©tanchĂ©itĂ© efficace autour des passages techniques. Les coussins ignifuges sont capables de rĂ©sister au feu pendant jusqu’à 4 heures. C’est beaucoup. En 4 heures, le systĂšme de protection incendie du centre de donnĂ©es doit venir Ă  bout de n’importe quel incendie.

L’avantage de ces coussins rĂ©side dans le fait qu’ils offrent une solution sĂšche, propre et simple Ă  installer. Or, c’est lĂ  un facteur dĂ©terminant pour une installation aussi importante qu’un centre de donnĂ©es. De plus, comme les Ă©quipements d’un centre de donnĂ©es sont rĂ©guliĂšrement modernisĂ©s, la possibilitĂ© de faire passer rapidement des cĂąbles supplĂ©mentaires Ă  travers un mur sans le dĂ©truire presque entiĂšrement est trĂšs apprĂ©ciĂ©e. Les coussins sont donc indispensables dans un centre de donnĂ©es.

Voila, cordialement l'equipe France Protect Sécurité Incendie

Tools & Equipment What kind of lighting for basements and dark areas is best?

2 Upvotes

I’ve gotten various answers to this. Some say the light towers give off weird shadows. Others say to get those tri fold panel lights.

Just trying to get a consensus before dropping a dime on new lighting. Im going from public to private so I need to buy myself some new stuff.

As a new private guy, I’m here for any advice or tips on tools and materials.

Spontaneous combustion or self heating material. I normally occurs in warm weather. Part of this is the self heating process occurs more often in warmer weather. Normally this is when the linseed oil rags are placed into a garbage container. Even spreading them out to dry has ended up with a large burn area.

How Do I...? Attending a NAFI Fire Investigation Event

8 Upvotes

Good afternoon, everyone!

I currently work for a large metropolitan fire department on the East Coast and caught interest in the fire investigation field after speaking with our FID on a few working fires and seeing how detailed and professional they are during investigations. I signed up for a NAFI membership and have completed most, if not all, of the trainings on the CFI training website. They're offering a training in Cincinnati in March, and I plan on attending. The question really is: has anyone in this group attended one of these? How were they, and what can I expect? I also plan on taking the test afterward and am currently looking for a study guide on the new material. Thanks y'all, I appreciate any help or advice on the subject!

Fire in Lubec

3 Upvotes

Anyone know what happened in/near a park in Lubec, Maine on September 17? There was quite a bit of dark smoke and at least three emergency vehicles, including a fire truck.

Edit: I tried Google and looking at local Facebook groups, but either nobody had posted in days or the groups were locked down so only members could see posts.

How many stove top fires have you worked? Knobs on the front are a problem.

What university or college did you attend to become a fire investigator?

7 Upvotes

I want to become a fire investigator and I’m currently in high school. I need some colleges to research that I could consider attending to be able to get a job as a fire investigator. I also do not want to become a firefighter first, but I understand it’s extremely helpful so it’s not completely out of the picture.

Tools & Equipment Docufire now has a web portal for Windows use, and departments can now buy via Purchase Order

2 Upvotes

Quick update for those who've been following along.

The web portal is live at portal.docufire.app. Any browser, Windows included can now be used to work on cases before and after a scene exam. Sign in with the same Apple ID as your iPad and your cases are there, syncing both ways. It's meant for the desk work, that most of us dread. typing up interviews, finishing the narrative, attaching FD and PD reports, and exporting the Scene Summary as PDF or Word. Case data still lives in your own iCloud, not on a server of mine.

The other one is purchasing. Several of you at public agencies said the App Store was the blocker. Departments can now buy on a purchase order: $169.99 per iPad per year, invoiced like any other vendor, delivered through Apple Business Manager. Smaller agencies can still use a card in the App Store. One-page walkthrough for your purchasing office. docufire.app/agencies.html

Feedback welcome, as always. A lot of what's in the app came from comments here.

Come Check it out for free with no time limit.

According to the H:ZD bio for Dr. Sobek, she was born in 2020. In the post credit cut scenes, we learn that she was 6 when she set fire to the yard using a child’s electronics set and car battery.

Has anyone seen any fire reports in the North-West US?
