👉 Caution fluid, often found in fire safety systems, is a type of fluid used to indicate the presence of combustible materials or gases in a confined space. It is typically color-coded, with different shades signaling varying levels of risk. A light green or yellow color usually indicates the presence of combustible dust, while darker shades like red or orange signify the presence of flammable gases. This fluid is crucial for ensuring safety in environments where dust explosions or fires could occur, as it helps operators and maintenance personnel quickly identify potential hazards and take appropriate precautions to prevent accidents.
