Dear All,
There is a requirement that all substations should have a minimum of two exits. I believe this requirement is from the Indian Electricity Rules. Can anyone direct me to the clause number where this is mentioned? I am unable to locate it. Looking forward to receiving help from any of the forum members.
Thanks in advance.

Dear Dipil,
I don't think sub-stations supposed to have minimum two EXIT’s I didn’t refer IE standard I don’t have it as well but I visited lot of substation most of them have one entry and one exit it vary from size of the Sub-Station building. I’ll try to pull the reference from NFPA 101-2009 (if you needed). I could be wrong though, so check it out.

Dear Dipil,
In NFPA 101 Life Safety Code 2009, Section 7.5.4.2 states that where two accessible means of egress are required, the exits serving such means of egress shall be located at a distance from one another not less than one-half the length of the maximum overall diagonal dimension of the building or area to be served. This distance shall be measured in a straight line between the nearest edge of the exit doors or exit access doors, unless otherwise provided in sections 7.5.4.2.1 through 7.5.4.2.3.
I will forward the NFPA 101 Life Safety Code 2009 to you now for your reference.

Dear Raghu,
Thanks a lot. Do share with me; I will check it out.
@ All: In the meantime, I came to know that the requirement is wide IS 1644 - 1988. Code of practice for fire safety of buildings (general): Exit requirements and personal hazard.
I have gone through it. There is nothing specifically mentioned about Electrical Sub-station. But I think with the below statements from IS 1644, we can come to a conclusion that it is required for substations also:
"2.7.1 General Requirement - All buildings which are more than 15 m in height and all buildings used as educational (B), assembly (D1), institutional (F), industrial (G1), storage (H), and hazardous (J) occupancies and mixed occupancies with any of the aforesaid occupancies, having an area more than 500 m2 on each floor should have a minimum of two staircases."
"2.7.13 Industrial (G) 2.7.13.1 Not less than two exits should be provided for every floor or section, including basements used for industrial purposes or uses incidental thereto."
If any of you have any further inputs, please let me know.
