Dear Mr. Dixon:

The purpose of this letter is to confirm your November 25 phone conversation with Mr. John Salkauskas of this office concerning safety latches on hooks. Section 29 CFR 1917.45(e)(2) of the Marine Terminal Standard requires that crane hooks be latched or otherwise secured to prevent accidental load disengagement. This obviously pertains to cranes in the marine terminal.

The longshoring regulations do not require safety latches on hooks for ship's gear. Section 29 CFR Part 1918.81(b) does require that cargo handling bridles which remain attached to the hoisting gear during successive draft be attached by shackles or some other positive means to prevent accidental disengagement.

We appreciate your interest in safety and health matters.
