This is the notable content prescribed in Decree 25/2019/ND-CP of Vietnam's Government amending and supplementing Decree 13/2011/ND-CP on the safety of onshore petroleum works.

Specifically, the safe distance from liquefied petroleum gas storage tanks stored under pressure to the protected objects and the distance between the storage tanks is stipulated in Decree 25/2019/ND-CP of Vietnam's Government as follows:

Tank capacity, V (m3)	Safety distance (m)		Distance between tanks (m)
Tank capacity, V (m3)	Submerged tanks	Floating tanks %	Distance between tanks (m)
V ≤ 0,5	3	1,5	0
0,5 < V ≤ 1	3	3	0
1 < V ≤ 1,9	3	3	1
1,9 < V ≤ 7,6	3	7,6	1
7,6 < V ≤ 114	15	15	1,5
114 < V ≤ 265	15	23	1/4 of the total diameter of two adjacent tanks
265 < V ≤ 341	15	30
341 < V ≤ 454	15	38
454 < V ≤ 757	15	61
757 < V ≤ 3785	15	91
V > 3785	15	122

For the safe distance from the tank to protected objects within DM&SPDM storage facilities:

Tank Volume (m3)	Safe Distance to Protected Objects (m)
Less than 1	1.5
Greater than 1 to 2.85	3.0
Greater than 2.85 to 45.6	4.5
Greater than 45.6 to 114	6.0
Greater than 114 to 190	9.0
Greater than 190 to 380	15.0
Greater than 380 to 1,900	24.0
Greater than 1,900 to 3,800	30.0
Greater than 3,800 to 7,600	40.5
Greater than 7,600 to 11,400	49.5
Greater than 11,400	52.5
