Storage of NH₃:
To store ammonia safely:
-
Use clearly labeled liquid storage tanks or containers to ensure easy identification.
-
Avoid filling containers with liquid ammonia beyond 80% of their capacity to allow for expansion.
-
Store in sealed containers placed in dry, cool, and well-ventilated areas.
-
Keep away from heat sources, high humidity, and flammable materials.
