What do the red and yellow discs in a fire extinguishing system indicate?

In a fire extinguishing system, the color coding of the discs plays a crucial role in indicating the operational status of the system. The red disc generally signifies a thermal discharge situation, meaning that the system has released its fire extinguishing agent due to a rise in temperature or a fire condition. This alerts personnel that the system has been activated and potentially discharged its contents to combat a fire.

The yellow disc, on the other hand, indicates a normal discharge status. This means that there has been no activation due to fire conditions, and the system remains fully charged and ready for use. This color coding helps distinguish between different operational states of the fire extinguishing system, ensuring that personnel can quickly assess and respond to the situation appropriately.

Understanding this distinction is important for safety protocols in environments where fire risks are present. Proper recognition of these indicators can significantly impact emergency response actions and overall safety management.
