Sec. 173.163  Hydrogen fluoride.

    Hydrogen fluoride (hydrofluoric acid, anhydrous) must be packaged in 
a specification 3, 3A, 3AA, 3B, 3BN, 3E, or 4A cylinder; or a 
specification 4B, 4BA, or 4BW cylinder, if the cylinder is not brazed. 
Filling density may not exceed 85 percent of the cylinder's water weight 
capacity. In place of the periodic hydrostatic retest, cylinders used in 
exclusive service may be given a complete external visual inspection in 
conformance with part 180, subpart C, of this subchapter, at the time 
such retest becomes due. Cylinders removed from hydrogen fluoride 
service must be condemned in accordance with Sec. 180.205 of this 
subchapter or, at the direction of the owner, rendered incapable of 
holding pressure.
