What must be ensured about components used in dry chemical extinguishing systems?

In dry chemical extinguishing systems, it is essential to ensure that only components that are listed for the specific system are utilized. This is critical for several reasons.

First, listed components have undergone rigorous testing and evaluation to meet established safety and performance standards set by organizations such as Underwriters Laboratories (UL) and the National Fire Protection Association (NFPA). These components are verified to work in harmony within the system, providing reliable activation and effective suppression of fires.

Using components that are not officially listed can compromise the system's integrity and effectiveness. Such components may lack the necessary certifications and could potentially malfunction or not perform as expected during an emergency situation. This adherence to using only listed components helps to mitigate risks and ensures compliance with safety regulations.

Moreover, relying on manufacturer specifications and listings enhances accountability. The manufacturers provide detailed guidelines on installation, operation, and maintenance, and using their listed components ensures that the system functions as intended, thus safeguarding lives and property.
