Upon reading the application and the contents on behalf of the Brotherhood of Locomotive Firemen and Enginemen and the Brotherhood of Locomotive Engineers; and upon the report and recommendation of the Chief Operating Officer of the Board,—

It is ordered: That the Rules and Instructions for the Inspection and Testing of Locomotive Boilers and their Appurtenances, prescribed by General Order No. 473, dated 22nd May, 1929, be, and they are hereby, amended by adding immediately after Rule No. 21 the following, namely:—

(21A). Hollow Rigid Staybolts.—Hollow rigid staybolts shorter than eight (8) inches shall have the tell tale hole extending throughout the length of the bolts of at least three-sixteenths (3/16) inch in diameter. When such bolts are used behind large brackets where it is desirable to direct the flow of water and steam in the case of a fractured bolt into the firebox, the outer end of such bolts may have the tell tale hole closed by electric welding or fire welding, and the inner or firebox end of such bolts shall have the tell tale hole kept closed with a fireproof porous material that will exclude foreign matter and permit leakage of steam and water if the bolt is broken or fractured.

Such staybolts, in addition to being tested as prescribed in sections 16 and 17, shall also be tested with an electric staybolt tester at the same time as prescribed for all hollow flexible staybolts in paragraph (b) of Rule 18. The testing of such staybolts with an electric tester shall be noted on the annual locomotive inspection and repair report required by this Order.
