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
