Do polyethylene tanks, to be used for drafting water into Fire Trucks, fall under the NFPA 22 requirements?
Depends. Water tanks, if they are for private fire protection, are within scope of NFPA 22. See sections 1.1 and 1.2.
Would have to look at 22 to see if it covers drafting tanks
I am thinking 22 does not, but some other standard may.
1.1 Scope. This standard provides the minimum requirements for the design, construction, installation, and maintenance of tanks and accessory equipment that supply water for private fire protection, including the following: (1) Gravity tanks, suction tanks, pressure tanks, and embankment-supported coated fabric suction tanks (2) Towers (3) Foundations (4) Pipe connections and fittings (5) Valve enclosures (6) Tank filling (7) Protection against freezing.
Plus local requirements
Looking at 22, I am thinking no, unless a requirement or city says to.
Maybe look at NFPA 1142
One cities approach
See number B 3 on page one
This information referenced by other:
According to the NFPA Technical Advisor board, this standard is specifically written to cover technical details which apply to fire suppression systems which employ fire suppression sprinklers. Water tanks used for drafting (water drawn into a fire truck) do not fall under the scope of NFPA 22. Under some circumstances, NFPA 1142 Annex-B can be referenced for underground cistern applications.
