Why do low smoke and halogen-free cable materials need to be tested for smoke density? The smoke density measurement of low smoke halogen-free cable materials is an important indicator for evaluating the combustion characteristics of cables or optical cables. This test is directly related to personnel evacuation and close range firefighting capabilities. According to the statistics of the fire department, about 80% of deaths in fires are caused by harmful gas poisoning, suffocation by diffuse smoke, or inability to escape due to the inability to see the path. Therefore, determining the minimum transmittance produced by cables or optical cables during combustion under specific conditions becomes a means of determining whether they meet specific requirements. Low smoke halogen-free cables typically have a low smoke density and a light transmittance of over 80%, which reduces the amount of smoke and facilitates personnel evacuation and firefighting. #LSZH #LSOH #HFFR #IEC61034 #safety #cable #sunua #smokedensity

Fire triangle and the Fire tetrahedron: The fire triangle and the fire tetrahedron are concepts used to understand the components necessary for a fire to ignite and sustain itself. Fire Triangle: The fire triangle illustrates the three essential elements required for a fire to start and continue burning: Heat – Sufficient temperature to ignite and maintain combustion. Fuel – A material that will burn (e.g., wood, gasoline, etc.). Oxygen – Typically from the air, supporting combustion. Without any one of these three elements, a fire cannot occur or will be extinguished. This concept is often used to teach basic fire prevention and firefighting strategies. Fire Tetrahedron: The fire tetrahedron expands on the fire triangle by adding a fourth component, illustrating a more complete model of fire behavior: Heat – Temperature that sustains the fire. Fuel – Combustible material. Oxygen – The element that supports combustion. Chemical Chain Reaction – This element reflects the ongoing process that sustains combustion after ignition has occurred. The fire tetrahedron acknowledges that fire is a dynamic process involving chemical reactions, which can continue even if some heat or oxygen supply is temporarily reduced. #fire #firetriangle #fire_Tetrahedron ARUN KAKKANAT HAMZA Akram

Efficient WATER hammer prevention with CSA surge tank with diaphragm filled with liquid S.P.T. The CSA surge prevention tank contains the devastating effects of water hammer, more precisely the transients coming from the sudden pump failure both for water and sewer systems. The device, fully automatic, is the ideal solution to avoid damages sometimes fatal for our systems as a consequence of uncontrolled overpressures and negative pressure waves. This is done through a smart solution where the bladder is filled with liquid and air is compressed between the bladder and the tank's wall which means no maintenance for the tank, and reduced stress for the bladder. Air safety device and frequent maintenance are also not need. We are welcome to simulate your case studies and provide our best solutions

Fire investigation, sometimes referred to as origin and cause investigation, is the analysis of fire-related incidents. After firefighters extinguish a fire, an investigation is launched to determine the origin and cause of the fire or explosion. Investigations of such incidents require a systematic approach and knowledge of basic fire science.

I've heard many folks complain about ASTM E1105. I have heard multiple individuals say that applying negative pressure on the inside of the curtainwall system is not representative of a rain event. We just had wind-driven rains with wind speeds exceeding 70 MPH in and around Houston. These were high pressures that push moisture into any opening in the building that can be found due to differential pressure. That's why field testing should be stringent, in my opinion. Field tests and lab tests should not represent regular precipitation events. They should be used as troubleshooting in preparation for significant storms,

During Emergencies, fire pump system plays a crucial role in maximizing safety. They provide the mechanical energy needed to overcome gravity and other factors that could impede water flow, thus playing a pivotal role in fire response efforts. Fire pumps operate on two main principles: Centrifugal Pumps Positive Displacement Pumps Below are our Centrifugal pumps set. #firesafety #firepumpsystems #serenepsl
