Accident Analysis: Talk about Bangkok Siam Commercial Bank Building fire extinguishing system of the accident March 13 – Article written by our Chinese Fire Safety Partner

All credit to Mr David Cao, our Fire Safety Partner in China for his article following the fire outbreak in Siam Bank in March. Mr Cao writes his views on the incident, on fire safety in more general terms and extols the advantages that Portalevel® MAX offers to fire safety management regimes. Mr Cao’s article has been re-published by 20 different Fire Brigades in China, including the Chinese Government Fire Department of Ministry of Public Security’s “China Fire” WeChat account and over 50,000 people have read his post.The views expressed are those of the Author and not the Company.

Follow us on LinkedIn & Facebook for regular updates & for our Chinese customers, Mr Cao is on WeChat “36safety£.

To sum up: You can determine that: The Siam Commercial Bank incident was a contractor improper maintenance of the system are not familiar with the case, the system is subjected to electromagnetic induction (a lot of sparks) cause an electric squib vessel by electromagnetic induction or an electric squib lead by more than 175 degrees Celsius accident system eruption.

Fires cause huge risk to the company and the environment is dangerous existence. Therefore, it is necessary to test the content of extinguishing agent fire suppression systems, and to ensure their normal operation and contain sufficient extinguishing agent. Weighing is a common method used to test. Fire safety standards prescribed amount of extinguishing agent is a method validation. However, the weighing method time-consuming. Each cylinder must be removed and weighed separately. This year is one of the reasons this method only once. Industry are increasingly aware of the risk of manual monitoring of fixed fire extinguishing systems, monitoring methods began to change. In the past, the owners comply with fire safety regulations, the most liberal part of the system checked once a year only. However, the owners want to protect important assets, this approach is not sufficient, because there is no consideration to the fire extinguishing cylinder slow leaks and accidental discharge.

Portalevel® ultrasonic non-invasive technology that enables users to check the exact level high degree of precision to +/-1.5 mm. Equipment clean, safe, easy to use - almost anyone can learn how to operate. Obtain UL certification Portalevel™ MAX is within the range of Portalevel ™ flagship model , is the need to test a large number of cylinders and design, especially some of the larger complex fire extinguishing systems, such as NOVEC 1230 (fluorinated ketone), FM-200 (heptafluoropropane) and other similar extinguishing agents, such as FE-13 (trifluoromethane), FE-25 (pentafluoroethane), FE-36 (hexafluoropropane) and carbon dioxide (CO2). Use this device (substituted lasted 30-60 minutes, at least two people to be demolished, weighed and re-install the cylinders labor-intensive methods) now takes only 30-60 seconds can show cylinder level.

Permalevel® Multiplex is the world's first fixed fire extinguishing agent level monitoring system. 24 hours a day year can simultaneously monitor 16 cylinders. Permalevel® Multiplex ensure the normal operation of the fire extinguishing system to protect high-value assets, infrastructure, and more importantly, to protect personal safety. Permalevel® Multiplex can monitor all common extinguishing agents include FM-200 (HFC227ea), NOVEC 1230, FE-13 (trifluoromethane), FE-25 (pentafluoroethane), FE-36 (hexafluoropropane), carbon dioxide (CO2) and water. It uses a standard 4-20 mA and connected to the existing alarm system, capable of sending alerts and system status digitized remote monitoring. A fully non-invasive external ultrasonic sensors, Permalevel® Multiplex has a non-destructive, will not weaken the structural integrity of the internal cylinder. Extinguishing system does not require an offline installation, to ensure the business continuity of critical infrastructure.
