Procedures & Safety Flashcards
Procedure for entering an enclosed space?
1) Risk assessment must be carried out by a competent person every time before entry.
2) List of work to be done.
3) Ensure space is empty if a tank and minimise fire hazards.
4) Open the space and secure any equipment.
5) Ventilate the space for a minimum of 24 hours.
6) Test the atmosphere at as many different levels and entry points as possible. Oxygen should read 20% or above.
7) Ensure sufficient lighting present.
8) Fill out a permit to work ensuring the space should only be entered by a trained and competent person.
9) PTW must be signed by master of the ship.
10) Situate signboards around the area.
11) Inform the duty officer before entering.
12) Checklist must be signed by the people entering and an authorised officer.
13) Ensure there is a standby man with a means of communication to those entering.
14) Bring EEBD or lifeline into the space and an oxygen monitor.
15) Situate rescue and resuscitation equipment outside the space.
16) Means of hoisting the person out must be available.
17) After finishing the work the after-work checklist should be filled out and permit to work closed.

What must a PTW include?
1) Location of the work.
2) Nature and limitations of work.
3) Details of the working team and tools to be used.
4) Potential hazards.
5) Precautions to be taken.
6) Protective equipment to be used.
7) Time and issue of validity.
8) Agreed communication methods and intervals.
9) Signature of person issuing the permit.
10) Signature of person entering the space.
What is the purpose of a risk assessment?
1) Minimise the possibility of accidents.
2) Identify hazards.
3) Decide control measures.
4) Find alternatives to mitigate risks.
How would you change the bearings on a motor?
1) Check the details of the job on the planned maintenance system.
2) Check for spare parts.
3) The day before consult the manual to refresh my memory of the procedure.
4) Ensure the equipment will not interfere with vessel operations.
5) Visit the work site and remember any potential hazards.
6) Complete a risk assessment of the work.
7) On the day, go through the process of completing a permit to work.
8) Describe the job to the team, complete a toolbox talk and ensure the wearing of correct PPE.
9) Isolate the device mechanically and electrically.
10) Prove isolations by draining the systems until depressurised.
11) Isolate the breaker on the switchboard and lock out tag out.
12) Check the electrical diagrams to ensure it cannot be energised from any other point.
13) Fit ‘work in progress’ and ‘do not start’ signs.
14) Prove dead first on a proving unit and then on the unit.
15) Once satisfied, get an authorised person to sign off on the permit.
16) Carry out the work as per manufacturers instruction.
17) Once complete, tell the team I will remove mechanical and electrical isolations.
18) Close the permit to work.
19) Tidy up worksite and tools.
20) Test the device to ensure correct operation.
21) Review the work that was carried out with the team.
22) Update the planned maintenance system, inventory and fill out the work diary.
What is condition monitoring?
Monitoring conditions such as vibration or temperature to identify changes that could indicate a developing fault.
What is the purpose of a permit to work?
Authorises certain people to carry out specific work within a specified time frame. It sets out the precautions required to complete the work safely.
What are the allowable atmosphere limits?
Oxygen - 20%
Flammable gas content - 1% LFL
CO - 20ppm
H2S - 5ppm
How would you prepare for arrival 1 hour prior?
1) Reducing sea speed to manoeuvring speed.
2) Change over to DO.
3) Start second generator and parallel.
4) Shut down FWG, changing over to high sea chest.
5) Start standby steering gear unit.
6) Drain air receivers and ensure standby compressor is ready for use.
7) Ensure auxiliary blower is in automatic.
8) Test ME operation astern, record in logbook.
9) When “standby” is rung, record FO and cylinder LO readings and engine rpm counters
What would you do upon arrival in port?
1) When “finished with engines” has been rung, the engine can be shut down.
2) Record flowmeters and ME rpm counters again.
3) Change to ER control.
4) Shut main air start valve and drain manifold.
5) Turn off auxiliary blower.
6) Open indicator cocks.
7) Engage turning gear and start rotating engine.
8) Open T/C drains.
9) The standby generator can be taken off board and shutdown.
10) After 15-30 minutes stop the turning gear and stop main LO pumps.
11) Open up JWC to ME to maintain engine in ready condition.
