what is the minimum volume for crude oil storage tank to install fixed fire fighting system

 

and if I have standalone crude oil storage tank in desert  , is it mandatory to protect it by fixed firefighting system 

[AdamMM]

Good day,

 

There may not be a straightforward answer to this. Typically, fire protection requirement is determined based on:

1. Local Regulations

2. Analysis of Fire and Explosion hazard 

3. Analysis of local condition (exposure to adjacent properties)

4. Availability of fire department or mutual aid response.

 

I remembered a discussion in NFPA 30, Chapter 22.8 that for vertical atmospheric fixed roof storage tank (Class-I Fluid) larger than 190 m3 requires a fire extinguishing system if located in a congested area where there is a risk of escalation from on to the storage tank. 

 

So, they are provided if risk warrants the provision and/or the local regulation requires the system to be installed.
