RFPEW-A1.3 Safe working practices as related to engine-room operations

Condition Behavior Standard

On a vessel, or in a laboratory,

the candidate takes up on a gate or globe valve stuffing- box gland.


The assessment applies to all RFPEW endorsements.

The candidate:

  1. Determines the need to take up on the gate or globe stuffing-box glands;
  2. Checks for bent or scored stem;
  3. Checks the valve for ease of operation, ensuring that it is a candidate for taking up on the gland without the necessity of adding packing or re-packing of the valve;
  4. Checks the position of the gland to determine if it may be further tightened;
  5. Tightens alternately each gland nut slightly and evenly until the stem-to-bonnet leakage ceases;
  6. Inspects the gland to insure that it is square; and
  7. Checks the valve for ease of operation ensuring that the operation is not unacceptably difficult.
