Which application has a distinct maximum quantity of NH3 compared to others?

The application that has a distinct maximum quantity of ammonia (NH3) compared to others is public assembly. This distinction arises from the specific requirements and regulations governing the use of ammonia in venues that host large gatherings of people. Public assembly spaces typically include places like auditoriums, theaters, and large event halls, which must adhere to stricter safety protocols due to the high occupancy rates and the potential for significant exposure in case of a leak.

These facilities are subject to guidelines that set limits on the quantities of hazardous materials, including ammonia, to ensure occupant safety and minimize risks during emergencies. Consequently, the maximum allowable quantities in these settings differ significantly from those in residential, institutional, or commercial contexts. The regulations tailored for public assembly environments emphasize both the need for safety in high-density population centers and the potential hazards associated with ammonia exposure.

In contrast, residential, institutional, and commercial applications may have different handling quantities and regulations for ammonia based on their specific operational environments, taking into account factors like typical occupancy and potential exposure levels.
