Aux 2 Unit 14 Q4

1. Quantity:

• Limit the quantity of petrol stored in hand-portable containers to a minimum, typically no more than 150 liters (40 gallons) per container.
• Larger quantities may require special approval or additional safety measures.

2. Location:

• Outdoor Storage: Store containers outdoors in a well-ventilated area protected from direct sunlight, rain, and extreme temperatures.
• Secure Lockers: If stored indoors, use dedicated, lockable lockers designed for storing flammable liquids. These lockers should be located away from heat sources, ignition sources, and areas with high traffic.
• Away from High-Risk Areas: Lockers should be positioned away from areas with electrical fittings, machinery, or other potential sources of ignition.

3. Ventilation:

• Open Ventilation: Lockers or open storage areas must have adequate ventilation with openings at both the top and bottom to allow for air circulation and prevent the buildup of flammable vapors.

4. Securement:

• Secure Containers: Containers must be securely fastened to prevent them from tipping over, falling, or moving during transportation or storage.  
• Locker Security: If stored in lockers, containers should be secured inside to prevent unauthorized access or theft.

5. Labeling:

• Clear Labeling: Containers must be clearly labeled with the type of fuel (petrol) and any hazard warnings.

6. Additional Considerations:

• Compatibility: Ensure the containers are compatible with the type of petrol being stored.
• Spill Containment: Consider using a drip tray or other containment measures to prevent leaks or spills.
• Fire Extinguishers: Keep appropriate fire extinguishers readily available in the vicinity of the storage area.  
• Authorized Personnel: Only authorized personnel should handle and store petrol containers.

Example:

A typical setup for storing hand-portable petrol containers might involve a dedicated locker on an open deck. The locker has openings for ventilation, a secure latch, and a clearly labeled sign indicating the presence of petrol. The container inside is secured with a tie-down to prevent movement, and a fire extinguisher is mounted nearby.

Important Note: Regulations and guidelines for the storage and handling of flammable liquids may vary depending on local jurisdictions. It is essential to consult relevant regulations and codes of practice for specific requirements and additional safety measures.

Storing petrol in hand-portable containers on the open deck of a vessel presents specific fire hazards, and regulations aim to minimize these risks. Here are the key requirements for stowing such containers in small lockers on the open deck:

1. Locker Location and Construction:

• Away from High-Risk Areas: Lockers should be situated away from:
  • Accommodation spaces and areas where people congregate
  • Engine rooms, machinery spaces, and sources of ignition
  • Ventilation intakes for enclosed spaces
• Dedicated for Petrol: The locker should be clearly marked and used solely for petrol storage, not for other equipment or materials.
• Construction:
  • Fire-resistant materials: Constructed from steel or other fire-resistant material.
  • Self-draining: The locker should have drainage leading overboard to prevent the accumulation of spilled fuel or rainwater.

2. Ventilation:

• Natural Ventilation: Openings at the top and bottom of the locker to allow for natural ventilation. This prevents the buildup of flammable vapors.

3. Container Securement:

• Securing within the Locker: Containers must be secured within the locker to prevent movement or damage during rough seas. This can be achieved with brackets, straps, or other suitable restraints.

4. Additional Safety Measures:

• Boundary Cooling: A means of cooling the locker’s boundaries (e.g., with a water spray system) may be required to prevent heat transfer in case of fire in adjacent areas.
• No Electrical Fittings: No electrical fittings should be installed within the locker to eliminate ignition sources.
• Gas Detection: Consider installing a gas detection system within the locker to provide early warning of leaks.

5. Quantity Limitations:

• Limited Capacity: The locker should be designed for a limited number and size of petrol containers, typically with a maximum capacity specified by regulations or the vessel’s safety management system.

6. Other Considerations:

• Compatibility: Ensure the containers and locker materials are compatible with petrol.
• Spill Containment: A drip tray or other means of containing spills within the locker is recommended.
• Fire Extinguishers: Provide suitable fire extinguishers near the locker.
• Authorized Personnel: Only trained and authorized personnel should handle and store petrol.

Example:

A small, dedicated steel locker on the open deck, painted with appropriate hazard markings, with top and bottom ventilation openings, a secure latch, and internal brackets to secure the petrol container.

Important Note: These requirements are based on general safety principles and common practices. Always consult the specific regulations and guidelines applicable to your vessel and jurisdiction for the most accurate and up-to-date information.
