What is passive protection?

Not quite sure, I’ll take part. Is passive protection the set of fire prevention measures that must be implemented in accordance with **or industry-specific fire safety standards for buildings? Such as fire-resistant building materials, fire separation distances, and so on? This is equivalent to passive defensive operations in war. Hehe. Proactive protection involves the installation and use of various fire-fighting facilities and equipment, akin to proactive offensive defenses in strategic defense. Ha. . Please forgive my nonsense.

Could the original poster tell us where the principles behind your fire protection design come from? The order of priority you mentioned is: passive protection – fixed fire protection systems – semi-fixed fire protection systems – manual fire protection systems. I’m not quite sure what you mean. If you could indicate the source, it might be possible to discuss this together. Here’s my personal understanding for reference: 1. Active protection: systems and devices such as automatic sprinkler systems, automatic gas fire extinguishing systems, and fire water curtains, which can detect fire incidents proactively and carry out firefighting actions or provide protection. 2. Passive protection: fire-resistant building materials, firewalls, fire shutters, fire doors, etc., which serve to passively reduce the risk and consequences of fires. Based on my understanding above, it seems that the order you mentioned isn’t correct

Agree with what was said on the third floor regarding active protection and passive protection

I’m still not quite clear about what is meant by the third floor. As for its origin, it is one of the fire protection design principles outlined in the LNG fire protection design specifications. The original text reads as follows: Fire protection design principles: 1. The selection of fire protection systems and the placement of fire protection equipment should be such as to reduce the scale, intensity, and duration of fire incidents as determined in the fire hazard analysis. 2. The priority order for selecting fire protection systems is passive protection, fixed fire protection facilities, semi-fixed fire protection facilities, and manual fire protection facilities. 3. The selected fire protection system and extinguishing agents, including seawater-based fire protection systems, must be capable of meeting the requirements of environmental conditions, so that they do not need to be replaced or damaged during a 25-year operation period, thereby preventing any reduction in or failure of the fire protection system’s functionality. 4. The fire protection system should be tested to ensure it meets the functional requirements and design intent. The design institute is China Chengda; principles 1, 2, and 4 should be followed in the fire protection design of all projects

I think the understanding of the 3rd floor is correct. First and foremost, it is necessary to implement passive fire protection measures, such as achieving a certain level of fire resistance, having firewalls in place, and raising the basic level of safety. Then, active measures should be taken to proactively address potential accidents. It seems that the hardware has met the requirements, and now the software is being improved to keep up. Nonsense. . .
