How to extinguish chemical plant fires quickly from a perspective of intrinsic safety
Thread Content
First question: Chemical processing involves numerous steps, a large number of devices that are closely arranged and connected to each other through pipelines. In the event of a fire, it is easy for the fire to spread rapidly due to these interconnections. From the perspective of intrinsic safety, what measures can be taken to limit the scope of the fire, or what methods can be used to extinguish it quickly once it breaks out? Second question: In the flowchart shown, each equipment container contains toluene. Will the flame spread along the pipelines from the tank to each of the devices one after another? Will the devices catch fire and explode, or will the solvent spill out? What measures can be taken to extinguish the fire quickly?
Essentially, analysis involves preventing it from catching fire, identifying and addressing potential hazards, responding promptly through chain reactions to extinguish the fire, and eliminating it at its earliest stages

It often turns from a small fire to a large one within minutes, spreading rapidly ； In many cases, the operators of this position may have suffered burns as a result of the fire ； It’s completely impossible to put out the fire with a 5kg dry powder fire extinguisher
Hazard sources should be managed at different levels, and for major hazard sources, measures such as monitoring must be in place, right? The chain reaction time is also very fast; shutting off the valves and activating the fire extinguishing system – of course, this is also the ideal scenario.
What method is used for fire extinguishing: sprinklers? How to determine which valves should be closed? If all of them are shut, pressure cannot be released – could this lead to an explosion? Are there any means for rapid fire suppression and pressure relief? In the event of an explosion, the factory’s structure will definitely be damaged and the area affected by the fire will get out of control
The SIS system shuts off the valves in case of situations that pose a threat to the equipment, thereby preventing the spread of such hazards
Alarm, shutdown, fire sprinklers.
Why does this ton barrel need to be on the first floor of the facility?
Is the material feeding area on the first floor? What do you think should be the placement?
Designate a separate area and isolate it with a firewall
In this design style, the equipment is placed within the box shown in the figure, using a combination of concrete and steel structures
