If there are not many items or the warehouse is not enough, they can be stored together because their properties do not conflict with each other; "firefighting" means that the properties of the two items do not conflict with each other, but the fire rescue methods are different, and it is best to store them separately if conditions permit; ① It means that peroxides such as sodium peroxide should not be stored together with inorganic oxidants; ② It means that nitrites such as sodium nitrite with reducing properties should not be stored together with other inorganic oxidants. For all mixed storage items, there must be a distance of more than 1m between the stacks, and the packaging containers must be intact to prevent the two items from contacting each other. 346
