9-11. ADDITIONAL INSPECTION CRITERIA (CONT).
Wood waterproofing is hazardous and flammable. Do not breath vapors and only apply
waterproofing in a well-ventilated area. Keep away from open flames. Wear protective
gloves and eye protection when applying waterproofing. Failure to comply may result in
injury or death to personnel.
Notify direct support maintenance or supervisor if welding or repair is required.
container length and no more than three partial length repair board sections throughout the entire flatrack floor are
permissible. Partial length repair board sections must span at least four crossmembers and be a material of similar
size and configuration as the rest of the flooring. Laterally adjacent repair board sections must not have joints on the
same crossmember. Both sides of each joint must be adequately supported by and securely fastened to the top
surface of a crossmember. If the top surface of the crossmember, such as a "Z" shaped type crossmember, is too
narrow a structural angle must be welded to it to provide an adequate support surface. The added angle must be
sized to extend beyond the adjacent floor board on each side of the repair section joint.
(4) Acceptable Floor Gaps. A flatrack is unacceptable if there is any excessive gap around the perimeter of
the flooring or between the floor boards. If a 1 in. (2.54 cm) wide by 1/16 in. (1.59 mm) thick feeler gage can be
easily inserted "vertically" through a gap to the underside of the flatrack, the gap is considered excessive. Narrow
gaps less than 1/2 in. (12.7 mm) wide, however, are permissible if sealed with caulking.
(5) Structural Integrity of Floor Structure. If the strength of the floor is in doubt, the dynamic floor weight
(concentrated load) test specified in Annex II (see Para 9-11j) of the International CSC should be conducted to
ascertain that: the understructure will not deflect more than 9/32 in. (7 mm) below the bottom surfaces of the bottom
corner fittings, no component will be permanently deformed and no component or weld will fail.
