Explosion Proof Lighting For Storage Tanks
Guidelines for night marking storage tanks with obstruction lights
Storage tanks are containers that hold liquids, compressed gases or oils. There are usually many environmental regulations applied to the design and operation
of storage tanks, often depending on the nature of the fluid contained within. Storage tanks are available in many shapes: vertical and horizontal cylindrical.
In refineries and especially for liquid fuels, there are fixed roof tanks, and floating roof tanks.
There is no single standard defining minimum mandatory requirements governing design and installation of obstruction lighting; on the other hand the most common and widespread regulations are ICAO's and FAA's.
Most important points to night marking storage tanks
Number and types of lighting levels (structure height)
H < 45m
1 level of low intensity obstruction lights shall be used
45m < H < 105m
2 levels of obstruction lights shall be used: top level with medium intesity, intermediate with low intensity
105m < H < 210m
4 levels shall be used: top with medium intesity, 1st intermediate with low intensity, 2nd intermediate with medium intensity, lower level with low intensity
Number of lights per level (structure diameter)
D < 6m
3 obstruction lights shall be used (120°) for storage tanks with circular base < 6m
6m < D < 31m
4 obstruction lights shall be used (90°) for storage tanks with circular base > 6m
D > 31m
6 obstruction lights shall be used (60°) for storage tanks with circular base > 6m

Most important points to night marking storage tanks
- lights and their arrangement shall be such that the structure is indicated from every angle in azimuth;
- the number of lights to be installed at the top and at each level depends on the diameter;
- the number of light levels depends on the height;
- lights shall be certified in accordance with ATEX/IECEx beacuse they are installed in hazardous and harsh environments.
