Can liquid ammonia and liquid nitrogen be kept in the same room?
Thread Content
May I ask, can liquid ammonia and liquid nitrogen be kept in the same room? Is it necessary to separate them? Is there a separate maximum storage capacity for liquid ammonia and liquid nitrogen?
There are strict requirements for storing liquid nitrogen; a proper safety distance must be maintained. When liquid nitrogen is stored alongside other substances, a safety distance of 25 meters is sufficient. Additionally, why store it indoors when ammonia tanks are usually placed outdoors? It is not appropriate to place it in a room; if it must be placed inside a building, blast-resistant walls need to be constructed on all four sides, and the only way for explosions to be dissipated is through the roof. Clearly, the surface area of the building itself makes it difficult to ensure the existence of such a discharge area.
Bottled liquid ammonia and liquid nitrogen can coexist in the same warehouse.
Liquid ammonia is generally not allowed to be kept in rooms, unless proper ventilation and protective measures are in place; it is advisable not to store it there at all
Liquid nitrogen is classified as belonging to Category B explosive hazard environments, while it is considered to be of ordinary risk level. If they are to be stored together, the storage capacity becomes an issue; the fire resistance rating of the building should also be set at the higher level appropriate for Category B explosive environments, plus an additional 2 levels of fire resistance. Alternatively, one could simply use a shed for storage, haha
