Maintaining Class A fire extinguishers primarily addresses hazards associated with common combustibles.

These materials are typically found in residential and commercial settings and represent a significant portion of the potential fire load in those environments.

The maintenance of Class A extinguishers is critical because failures or malfunctions in extinguishing systems can lead to ineffective fire response, increasing the risks associated with these common combustibles.
