Division II’s Final Day of Training  
The third day of training for cadets in Division II concluded today as the TS Kennedy was nicely making way towards the third port of Willemstad, Curacao. This is the last day in the three-day cycle that the cadets in this division will be attending classes as part of their Sea Term. For the 4th Class cadets in the  2020 Sea Term I Deck Training Program, this meant attending four separate classes; Crane Signals, Fall Protection, Merchant Marine, and JSA/SDS.

As an aside, the clocks onboard the ship will be advanced by one hour tonight (20 minute intervals during three separate watch cycles) as we continue our journey to the West in the Caribbean Sea.

The waters have been a little wild as of recently, so a handful of cadets have reported being somewhat seasick.

Crane Signals With Captain Brady  
The morning began with Captain Brady’s lesson on Crane Signaling in classroom 6-4. Using a variety of hand signals, a person is able to communicate non-verbally with a crane operator so as to give the operator commands as to what action to take next with the load. Using fishing poles on the deck of the ship, each of the cadets was able to practice signaling to another cadet on the deck above to hit the target on the deck below them without using spoken words. During the on-loading process
before we were underway, the 1st Class cadets had to use these same commands when acting as the “Runner” for the crane operator on the stern of the ship as pallets were loaded into 1st Hold. Here is a list of the signals we learned how to use;

1) Hoist Load: Hand facing upward with a pointed index finger moving in a circle
2) Lower Load: Hand facing downward with a pointed index finger moving in a circle
3) Hoist Load Slowly: Flat left hand held horizontally above right hand facing upward with a pointed index finger moving in a circle.
4) Lower Load Slowly: Flat left hand held horizontally beneath the right hand facing downward with a pointed index finger moving in a circle.
5) Raise Boom: A thumb up
6) Lower Boom: A thumb down
7) Stop: Shake your flat hand horizontally once
8) Emergency Stop: Frantically shake your flat hand horizontally repeatedly
9) Dog Everything: Lock your hands together by the thumbs and keep them closed together

SDS/JSA With Mate Lisa Burke
The last class of the day was with Mate Lisa Burke, who educated the cadets on Safety Data Sheets (SDS) and Job Safety Analyses (JSAs), which are both crucial to occupational health and safety while onboard a ship. The SDS (also called a material safety data sheet) is a comprehensive digital or printed guide that identifies the various aspects of a substance that can be found in the work environment, including melting point, boiling point, flash point, health risks, first aid, reactivity, occupational exposure limit, the type of PPE (personal protective equipment) necessary, disposal, storage instructions for safe use and potential associated hazards. As part of the exercise, the class went to the Metal Steering Gear Room located in the deck beneath the Fantail. Here, a SDS binder is kept that outlines the factors associated with the chemicals used in this area (example lubrication oil for the Steering Gear).


A Job Safety Analysis, or JSA as was explained by Mate Burke (also called a JHA, or Job Hazard Analysis) is a tool used to identify the hazards associated with a specific job. A hazard is defined as any potential for harm if left uncontrolled. These can vary from workplace to workplace or ship to ship. The JSA is meant to focus on the relationship between the worker, the task, and safety requirements while minding the three factors that must be protected; people, property, and the environment.

There is a hierarchy of risk-controlling means that can be employed to mitigate or exclude the risk entirely. With any given hazard, Elimination, Substitution, Engineering Controls, Warnings, Administration, or PPE (arranged from most to least effective) can be utilized to address the risk factors.
