List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1 | Determine characteristics of tanker cargo and tankers to ensure safe transfer and transport of cargo | 1.1 | Features of various types of liquefied gas tankers are outlined |
1.2 | Cargo operations of tankers are identified |
1.3 | Properties of cargo being transported are identified and their impact on safety, the environment and vessel operations are outlined |
1.4 | Hazards associated with the transport of cargo are clarified according to emergency response documentation |
1.5 | Hazard controls associated with tanker cargo are employed according to organisational procedures |
2 | Comply with legislative and organisational requirements for safe transfer and transport of tanker cargo | 2.1 | Safety data sheets (SDS)/material safety data sheets (MSDS) relevant to cargo are accessed and procedures for tanker safety and safety management are identified |
2.2 | SDS/MSDS are interpreted to identify relevant cargo-related hazards to the vessel and to personnel |
2.3 | Legislative and organisational requirements are interpreted to identify appropriate actions for safe transfer and transport of cargo |
3 | Take precautions to prevent hazards | 3.1 | Organisational policies and procedures to minimise hazards are identified |
3.2 | Type and severity of the hazard posed by cargo is recognised |
3.3 | Transfer and transport of cargo is monitored to prevent hazards |
3.4 | Gas monitoring equipment is regularly inspected and used according to organisational procedures |
4 | Act on becoming aware of a hazardous situation | 4.1 | Source of hazard is identified according to organisational procedures |
4.2 | Risk is assessed considering severity and likelihood of consequences |
4.3 | Control measures to minimise risk are implemented to level of responsibility or referred to appropriate person for further action |
4.4 | Containment procedures are applied where appropriate |
4.5 | Appropriate safety procedures are followed and personal protective equipment is used according to organisational procedures |
4.6 | Risk is eliminated where possible, and if not practical, actions are taken to control risk |
5 | Take precautions to prevent pollution of the environment from release of liquefied gases | 5.1 | Procedures to prevent pollution are identified and observed at all times |
5.2 | Measures to prevent pollution during normal and emergency situations are applied according to regulatory requirements and organisational procedures |
5.3 | 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 |
5.4 | Shore-based response personnel are promptly notified when a vapour leak or cloud occurs |
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:
communicating clearly and effectively
correctly identifying 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
