I’ve never seen it; I don’t know under what circumstances it occurs, I’ve just never encountered it
Yellow phosphorus is highly penetrative, dangerous, and highly toxic; therefore, protective covers must be used on all flange connections
We generally use them in corrosive and high-temperature environments, such as acids, alkalis, steam, etc., where leaks or splashes from these substances can cause injury.

The safety splash protection device ensures safety for personnel, equipment, and the environment. In industrial production systems, there are numerous pipelines used to transport liquid hazardous materials. Due to the high corrosiveness of these liquids, and issues such as thermal expansion and contraction as well as aging of the flange gaskets, leaks can occur, leading to the splashing of liquid. Flange guards serve as safety devices that prevent hazardous liquids from causing harm, and they also help to slow down the rate of corrosion of the flanges. Flange guards are primarily used to prevent the flanges from not fitting tightly during connection, or to avoid liquid splashing and leakage caused by excessive pipeline pressure, thus providing effective protection for on-site workers and surrounding equipment. Safety first, prevention foremost; accidents should not be addressed only after they occur. It is necessary to strengthen safety measures, especially in management, where effective protective actions must be taken. The media transported through pipes connected by flanges are often highly corrosive substances at high temperatures and pressures. If the flanges are not sealed properly during connection or if the pressure in the pipes is too high, liquid splashing and leakage can occur, which can easily cause harm to the workers on site and the surrounding equipment. The function of flange guards is to provide effective protection against such accidental damages. Therefore, more and more manufacturing enterprises are now realizing the importance of prevention and taking steps to avert problems before they arise.
For example, things like concentrated sulfuric acid, high-temperature materials, alkaline solutions, hydrochloric acid, and so on.
The principle is that pipelines without insulation, in the event of a leak, can expose people to hazardous materials
