Elements and Performance Criteria

1. Determine characteristics of tanker cargo and tankers to ensure safe transfer and transport of cargo
   • Features of various types of liquefied gas tankers are outlined
2. Cargo operations of tankers are identified
3. Properties of cargo being transported are identified and their impact on safety, the environment and vessel operations are outlined
4. Hazards associated with the transport of cargo are clarified according to emergency response documentation
5. Hazard controls associated with tanker cargo are employed according to organisational procedures
6. Comply with legislative and organisational requirements for safe transfer and transport of tanker cargo
   • Safety data sheets (SDS)/material safety data sheets (MSDS) relevant to cargo are accessed and procedures for tanker safety and safety management are identified
7. SDS/MSDS are interpreted to identify relevant cargo-related hazards to the vessel and to personnel
8. Legislative and organisational requirements are interpreted to identify appropriate actions for safe transfer and transport of cargo
9. Take precautions to prevent hazards
   • Organisational policies and procedures to minimise hazards are identified
10. Type and severity of the hazard posed by cargo is recognised
11. Transfer and transport of cargo is monitored to prevent hazards
12. Gas monitoring equipment is regularly inspected and used according to organisational procedures
13. Recognise hazardous situation
    • Source of hazard is identified according to organisational procedures
14. Risk is assessed considering severity and likelihood of consequences
15. Control measures to minimise risk are implemented to level of responsibility or referred to appropriate person for further action
16. Containment procedures are applied where appropriate
17. Appropriate safety procedures are followed and personal protective equipment (PPE) is used according to organisational procedures
18. Risk is eliminated, where possible, and if not practical, actions are taken to control risk
19. Take precautions to prevent pollution of the environment from release of liquefied gases
    • Procedures to prevent pollution are identified and observed at all times
20. Measures to prevent pollution during normal and emergency situations are applied according to regulatory requirements and organisational procedures
21. All relevant information is immediately reported to appropriate persons when a vapour leak or cloud is detected or a malfunction has occurred that poses a risk of a vapour leak or cloud
22. Shore-based response personnel are promptly notified when a vapour leak or cloud occurs

Range Statement

Range is restricted to essential operating conditions and any other variables essential to the work environment.

Performance Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria on at least one occasion and include: assisting in implementing shipboard spill containment procedures communicating clearly and effectively contributing to cargo operations in accordance with principles and procedures identifying hazards, assessing risks and applying control measures in accordance with safety management systems (SMS) measuring for gas using monitoring instruments reading and interpreting safety data sheets (SDS)/material safety data sheets (MSDS), relevant cargo-related hazards to vessel and to personnel, and taking appropriate action according to organisational procedures recognising problems and hazards that can arise when managing safety on a liquefied gas tanker in accordance with SMS reporting relevant information to the responsible person.
