My question was:

Using a portable extension ladder, how far above the elevated surface must your ladder extend?

Answers

2.5 ft
4 ft

I can't find the info. What book is it in?
 
It is an OSHA requirement and I thought it was 3', so the answer may be 2-1/2'

3' may have been one of the answers. thanks.

The answer must have been in the 'Code of Federal Regulations' which I do not have.

I do not really understand the question, are you referring to the overlap? From osha:

1910.26(a)(2)(iii)

Based on the nominal length of the ladder, each section of a multisection ladder shall overlap the adjacent section by at least the number of feet stated in the following:

______________________________________________________
|
Normal length of ladder (feet) | Overlap (feet)
____________________________________|________________
|
Up to and including 36 .............| 3
Over 36, up to and including 48 ....| 4
Over 48, up to 60 ..................| 5

OSHA 1926.1053(b)(1)

When portable ladders are used for access to an upper landing surface, the ladder side rails shall extend at least 3 feet (.9 m) above the upper landing surface to which the ladder is used to gain access; or, when such an extension is not possible because of the ladder's length, then the ladder shall be secured at its top to a rigid support that will not deflect, and a grasping device, such as a grabrail, shall be provided to assist employees in mounting and dismounting the ladder. In no case shall the extension be such that ladder deflection under a load would, by itself, cause the ladder to slip off its support.
