17.04 Is fire protection required for pipe in buildings and how is it provided?

Local regulations may require fire protection for fuel piping in buildings where it is routed outside special rooms such as generator rooms, boiler rooms, and tank storage rooms. Typically 2 hour fire protection is required.

A typical method of providing the fire protection is by insulating the pipe with fire rated insulation.

A common alternative method is to route the piping through fire rated shafts which are often provided for utility risers in multi-story building.

Either method prevents visual inspection of the piping, so double contained pipe with leak detection is typically used.
