Aboveground tank separation distances
Separation distances from a tank to the property line, to a road and to adjacent tanks.
The separation distances follow from the liquid's classification, the tank's capacity and the protection provided, and they determine the site layout.
Demonstration scenario
A 50 m³ tank, fixed roof, flammable liquid
The tank
- Capacity
- 50 m³
- Diameter
- 4.2 m
- Roof type
- Fixed roof
- Liquid classification
- Taken from the liquid classification in the project
Protection
- Cooling protection
- None
- Containment
- Bund
- The distances depend on the liquid's classification; changing the classification changes the whole result.
- The tool will use the classification already verified in the project and will not ask for it again.

NFPA 30 (2024), chapter 22 — separation distance tables
The edition is known from the procedure. The tables' contents require an authorised copy.
What is blocked, and what would release it
NFPA 30 (2024) — chapter 22, the separation distance tables
The distance tables depend on the liquid's classification, the tank diameter and the protection provided. None of them appears in the Israeli procedure.
We currently have no legitimate route to obtain the document.
Until the source is obtained, the tool shows the interface and the calculation steps, and presents no regulatory value.
