Storage Conditions

Keep container tightly closed in a dry and well-ventilated place. Contents under pressure. Storage class (TRGS 510): Gases
Before entering confined space where this chemical may be present, check to make sure that an explosive concentration does not exist. Protect against physical damage. Outside or detached storage is preferred. Inside storage should be in a cool, well-ventilated, noncombustible location, preferably with automatic monitoring systems, away from all possible sources of ignition. Separate from other chemicals, particularly oxidizing gases, chlorine, bromine, iodine, and acids.
SRP: Operations involving entry into tanks or closed vessels, and emergency situations, require consideration of potentially oxygen deficient, or "immediately dangerous to life and health" IDLH environments. This may necessitate use of a self-contained breathing apparatus (SCBA), or a positive pressure supplied air respirator.
Separate from other chemicals, particularly oxidizing materials, acids, and halogens. Store in a cool, dry, well-ventilated location.
... May be stored under high pressure, refrigerated at low pressure, or as aqueous ammonia in low pressure tanks.
Storage temperature: Ambient for pressurized ammonia: low temperature for ammonia at atmospheric pressure.
Permanent storage containers shall be located at least 50 feet from a dug well or other sources of potable water supply, unless the container is a part of a water-treatment installation.
