Sistemas de Espuma

Se conoce también como sistema de inundación. Se usa en áreas de alto riesgo donde las características combustibles de los materiales involucrados, hacen necesario un cubrimiento completo a fin de evitar una rápida propagación del incendio.

La red de tubería recorre todas las áreas a proteger y los rociadores “abiertos” están distribuidas adecuadamente. La espuma es un agente extintor que es empleado principalmente para combatir incendios que involucran sustancias inflamables. La espuma se forma a base de un agente espumante, el cual se mezcla con agua en un equipo proporcionador, formando una solución.

Esta solución pasa luego a los dispositivos generadores de espuma, en los cuales se produce una aireación de la solución, transformándola en espuma, la cual sale por las regaderas abiertas.

La espuma forma una capa que cubre las superficies combustibles, produciendo un doble efecto de enfriar y evitar el contacto con el aire. Además evita la emanación de vapores combustibles, previniendo la reiniciación del fuego. Tiene además la característica de adherirse a las superficies que cubre, protegiéndolas de los fuegos adyacentes. Los agentes espumantes son de varios tipos, dependiendo del tipo de espuma a generar y de la naturaleza de las sustancias inflamables a proteger.

Por lo general, los sistemas de espuma se usa en sistemas de inundación total, controlados por una válvula tipo «Diluvio», accionada mediante un sistema de detección (que puede ser mediante regaderas comunes de ampolla o fusibles, detectores de humo, detectores de calor, etc.…).

 

 

 

 

 

ALLEN PARK, Mich. -- Periodically during training camp and then on Saturdays during the regular season, we’ll answer at least one of your questions in a weekly mailbag. Golden Tate III Jerseys This is an interesting question because so much goes into it for the Detroit Lions running back. Marvin Jones Jr Jerseys Start here, that the Lions have never had a strong running game under Jim Caldwell. Caldwell has never had a run game in the top half of the league in his time as a head coach in Indianapolis and Detroit or as an offensive coordinator in Baltimore.

With that knowledge, set expectations accordingly. That said, Ameer Abdullah is in a good spot with the Lions. Matthew Stafford Jerseys He clearly is the team’s No. 1 running back and should get almost all the work on early downs with Theo Riddick being a pass-catching specialist and Zach Zenner having more of a goal-line presence. Ameer Abdullah Jerseys Dwayne Washington is a wild card, but at this point Abdullah is the better player -- and it isn’t close. From what I’ve seen from Abdullah, the Lions should be pleased with what they have. He has looked sharp throughout training camp and appears to have retained the speed and agility that made him an intriguing back before his foot injury.

With all of that knowledge, I’m going to make a bold prediction: If Abdullah stays healthy for all 16 games this season (or even if he plays 15), he ends up as the team’s first 1,000-yard rusher since Reggie Bush in 2013. Barry Sanders Jerseys Not going to say he’s going to go much over 1,000, and I think his touchdown numbers could be low because of Riddick as a pass-catcher and Zenner or Washington as a bigger option, but the yardage and volume should be there for Abdullah. That said, if you're looking for a true over/under line, I would probably be safe setting it at 750 yards (which I think he'll be way over). If Abdullah averages 15 carries a game -- and that’s fairly reasonable -- he would have 240 carries over 16 games. At that rate, he would have to average 4.17 yards per carry to reach 1,000 yards.
