Prepare for a Malfunction | Corona, CA

fire sprinklersWe all assume that if we have fire protection, it will work when the time comes to use it. Whether it be something simple like a fire extinguisher or as elaborate as a customized fire suppression system, these tools are things we need to rely on when a fire breaks out. If it doesn’t, the result can be a disaster.

It’s important to note that simply installing a suppression system is only one step in staying safe. Fire suppression systems are often complex pieces of engineering, and they require care, testing, and maintenance in order to remain functional.

The type of system installed, and the nature of the building it is protecting, will determine how often it must be inspected, how often it should be tested, and what type of labor will be required on the system over time. A skilled system designer, such as CJ Suppression, will not only design the system, but can also assist you in establishing and meeting the maintenance and inspection requirements in order to keep your system functioning properly so that if a fire were to occur, lives and property can be saved.

The exact maintenance regime needed depends on the suppression system and use case. The National Fire Prevention Association (NFPA) has guidelines not only for the types of systems that should be used in various settings, but also for the ongoing maintenance of those systems for proper compliance and safety purposes.

To ensure their reliability, fire systems must be inspected, tested and maintained. CJ Suppression Services’ qualified and experienced staff stands ready to provide fire protection service and maintenance that will keep your fire protection systems reliable and code compliant.

Dozens of Massachusetts Homes Exploded. A Gas Expert Weighs In. | Corona, CA

by RACHEL GUTMAN

SEP 14, 2018

WCVB / AP

Investigators still don’t know what happened, but there’s one likely explanation.

Late Thursday, dozens of explosions erupted in three towns in northern Massachusetts. As many as 70 fires, explosions, and suspected gas leaks were reported to state police, with at least 39 homes affected in Lawrence, Andover, and North Andover. One person was killed when a chimney collapsed on his car, and at least 25 more people were reportedly treated for injuries.

In a statement, Columbia Gas said a total of 8,600 customers will be without service until safety teams can ensure that their homes and businesses are leak-free.

A widespread series of explosions like the one in Massachusetts is “really rare,” says Robert Jackson, a professor of energy and environmental science at Stanford University. Jackson’s studies focus on the environmental impacts of natural gas, and he has mapped thousands of gas leaks in cities around the country, including Boston. He told me that such an event is “unprecedented in recent years,” since explosions are usually isolated to a single building.

Jackson is not involved in investigating the Massachusetts explosions, but he was able to offer some insight into what could have caused such a strange, dramatic incident. The most likely explanation, he says, is the one most reports have speculated: Pipelines in the towns became suddenly over-pressurized. In the same way that high-voltage power lines traverse hundreds of miles before breaking off into lower-voltage tributaries in neighborhoods, natural-gas delivery systems consist of both long-distance, high-pressure pipelines and local ones that are only nominally pressurized and deliver gas into homes. Neighborhood pipelines are usually designed to withstand two to three times their normal operating pressure, but any increase makes gas more likely to escape.

“I can’t imagine another explanation for this event than a flush of pressurized gas,” Jackson says.

If local lines indeed were suddenly inundated with high-pressure gas, Jackson says, that could result in an explosion in one of two ways. First, the pipes themselves could explode. Second—and more likely, according to Jackson—excess pressure could have caused gas to leak out of pipes and valves and into homes, where it could be ignited by a pilot light and send whole buildings up in flames.

In most cases, according to Jackson, such rapid pressurization would be caused by a failure at a valve that separates high- and low-pressure pipelines. As for what would lead to such a failure, Jackson says, it could be that “somebody made a mistake. To flip the wrong valve, leave a junction open. Human error is the most common source of natural-gas explosions.”

Columbia Gas’s website announced an improvement campaign just a few hours before the explosions began, though no evidence has yet linked the explosions to pipeline updates or botched repairs. (A spokesperson for Columbia Gas did not respond to a request for comment.)

A flush of gas could also occur if older valves leak or break. In 2015, Jackson and his colleagues found that cities like Cincinnati that replaced their aging pipelines had 90 percent fewer gas leaks a mile than older cities like Boston that relied on older, cast-iron pipes. Across the country, Jackson says, many local pipelines are more than a century old—including in Boston, the closest major city his team studied to Thursday’s explosions.

Even though natural-gas leaks are fairly common, serious consequences aren’t. From 1998 to 2017, 15 people a year, on average, died in incidents related to gas distribution in the U.S. “Significant incidents”—those that do things such as cause an injury or death, result in at least $50,000 of damage, or lead to a fire or explosion—happen about 286 times a year.

That might sound like a lot. But then again, the streets of Boston carry an average of four gas leaks a mile.

 

How to Protect a Datacenter from Fire | Corona, CA

Do you know what a datacenter is? Datacenters are built specifically to house millions of dollars of expensive electronics and contain custom-built solutions for everything from cooling to power continuity and generation. Due to the 24/7 nature of datacenters, most systems are designed for redundancy and fail-safe operation with cabinets of battery-powered, uninterruptible power supplies reside to complement generators.

But what if there’s a fire? Computers present a unique fire suppression challenge – they’re easily damaged by water, are typically contained in a metal box that will shelter a fire from overhead sprays, and they require significant amounts of electricity that presents an electrocution risk for standard suppression systems. Because of this, typical datacenter suppression systems come with two complementary systems – one wet, and one dry.

Modern alternatives tend to be either inert gas systems (where an inert gas is pumped into the datacenter to smother the fire by depriving it of oxygen) or clean agent systems, where halocarbon molecules are pumped in and absorb heat, extinguishing the fire.

While dry systems are often the first line of defense, due to their ability to extinguish fire without damaging equipment, a second water-based system is typically available. Best practices often dictate that the pipes above the datacenter itself be dry – that is, pipes are not filled with water until a fire is indicated, at which point the pipes are filled. Typical configuration allows the clean agent or inert gas system to attempt to put out the fire long before the heat allows a sprinkler to discharge.

Inert Gas Fire Suppression

ThinkstockPhotos-479155414Inert gas fire suppression systems are considered one of the safest and most natural ways of extinguishing fires. The system relies on the use of naturally occurring inert gasses, which are found all around us, such as from the air we breathe.

How Does The System Work?

The air we breathe is composed of around 21% oxygen. Aside from being what exactly helps sustain life, oxygen is also a key factor in sustaining a fire. This means that if you remove oxygen from the air of the hazard area, the fire always goes away as well. Although, doing so creates another problem, how do you sustain life without oxygen?

The answer is simple – by removing enough oxygen to prevent fire from burning, but also keep enough to ensure survival.

In a hypothetical scenario, the system works by reducing oxygen from 21% to lower than 15%, but still higher than 12%. Doing this, the system is able to extinguish all flames and sustain life at the same time.

It is, however, important that the system be checked, maintained and most important of all, properly installed to prevent it from reducing oxygen levels to below 12%.

Should that happen, you will be at risk for the following:

  • Shortness of breath. Once oxygen levels are below 12%, the respiratory system will no longer be able to function properly. You’ll experience shortness of breath, even when you’re resting or sitting down, and your blood oxygen saturation will steadily fall.
  • You will get tired and feel more exhausted faster than normal. You may not even be able to move much at all.
  • Confusion and disorientation. As your body, mainly the brain, is starved of oxygen, your cognitive abilities will become hampered and you’ll find yourself confused and disoriented.
  • You’ll soon experience headaches as your brains are further starved of oxygen. If the oxygen levels drop even further, your symptoms will become worse and you may find yourself in a life-threatening situation.

Is The System At Risk Of A False Alarm? 

These systems often utilize detection and activation systems consisting of a network of detectors, commonly referred to as a double knock. The use of the double knock system ensures that the system will only go into a fire stage alarm if the first detector senses fire. However, the system will reset automatically or remain in the first stage until a second detector senses an even worse threat. If that happens, the second detector activates the second alarm and a countdown to gas discharge begins.

A High Sensitivity Smoke Detection Aspiration System or HSSD can also be installed. The system allows potential fires to be investigated early to prevent additional expenses and unnecessary gas discharge.

With the world leaning more towards “green” and cost-effective systems, inert gas fire suppression systems have become a popular option today. It also doesn’t hurt that the system is not only cost-effective, but also safe and efficient enough to help control fires and make sure that accidental damage is kept to a minimum. However, it is important to remember that the system has to be maintained, inspected and most important of all, installed properly to ensure the safety of your people and your assets.

Inert Gas Fire Suppression Systems – CA

CJ Suppression installs inert gas systems as one of the clean agent alternatives replacing traditional Halon 1301 systems. Inert gas is a high-pressure agent stored in cylinders similar to carbon dioxide. This agent is a blend of naturally occurring inert gases, namely Nitrogen and Argon. Because the gas blend is inert, it has a broad spectrum of application, being both safe for human exposure and very effective on many types of fires, including industrial-based and flammable liquids.

Inert gas systems are designed with a central bank of cylinders manifolded together, with the agent distributed through a pressure reducing piping network utilizing engineered nozzles.
