Let’s talk about how to avoid an explosion
Thread Content
Most explosions are caused by fires. I haven’t really thought through how to avoid explosions – what are the ways to do that?
By eliminating the conditions that cause an explosion, it can be avoided.
As the original poster said, one first needs to consider the conditions for an explosion, which are essentially flammable materials, oxidizing agents, and an ignition source; controlling any one of these elements will do. For example: pipelines for transporting flammable liquid materials must be electrically grounded, and the flow rate must be controlled to prevent static electricity buildup; moreover, submersible feeding methods should be used for pipelines feeding into tanks ； This topic is a bit broad; I’m not sure how to address it, haha
How to avoid the three aspects of combustibles, oxidizers, and ignition sources
Operate within the load limit; leave a margin for design purposes
In essence, an explosion incident is always a result of material leakage; to prevent explosions, it is necessary to keep the materials within the system and prevent outside air from entering it
I remembered an incident where an oxygen valve exploded; there was a problem with the valve itself, and as high-pressure oxygen flowed through it, the valve exploded right away
I originally wanted to ask what procedures should be followed for different media and systems in order to prevent fires and explosions For example, personnel must not leave the site when cutting water from liquefied gas.
To avoid an explosion, it is sufficient to eliminate the conditions that lead to one, and then no explosion will occur.
An explosion is the release of energy, and energy includes thermal energy, kinetic energy, potential energy, electrical energy, and wind energy； It is necessary to control the quantity and state of matter and energy at the source in order to reduce risks.
If HAZOP is carried out in advance and preventive measures are taken, then it’s fine!
