According to the B-52 code, what is the maximum amount of refrigerant that can be stored in a mechanical room?

The B-52 Code sets guidelines for the safe storage of refrigerants in mechanical rooms to ensure compliance with safety standards and to minimize the risks associated with potential refrigerant leaks or emergencies. According to this code, the maximum amount of refrigerant that can be stored in a mechanical room is specified as 300 lbs. This limit is established to balance the need for sufficient refrigerant for operational purposes while also maintaining safety by preventing excessive accumulations that could pose hazards in the event of a leak or fire.

This regulation helps in managing the risk of exposure and ensuring that appropriate safety measures, such as ventilation and containment, can be effectively implemented within the designated area. Understanding such limits is critical for anyone involved in the maintenance and operation of refrigeration systems, as it promotes safe handling practices and adherence to regulatory requirements.
