Study Notes

Safety on Ship

Safety on ships is critical due to isolation at sea, often far from assistance.
Human error is a leading cause of accidents on board.
The Marine Safety Committee (MSC) of the IMO establishes safety regulations for ships.

Fire Safety

Combustion requires heat, oxygen, and fuel; all must be present for ignition.
Portable fire extinguishers are designed to combat small fires before they escalate.

Types of Fire Extinguishers

Water Extinguisher (Signal Red)
- Ideal for solid materials (wood, cloth, paper).
- Not suitable for fat/oil or electrical fires.
- Cools fuel surfaces to reduce combustion.
Powder Extinguisher (Blue)
- Effective on solids, liquids (grease, oil, paint), and gas fires.
- Safe on live electrical equipment but may re-ignite.
- Acts as thermal ballast, cooling flames.
Carbon Dioxide Extinguisher (Black)
- Best for live electrical equipment; may cause re-ignition of hot surfaces.
- Can asphyxiate in confined spaces; requires ventilation.
- Works by displacing oxygen, suffocating the fire.
Foam Extinguisher (Cream)
- Suitable for solid and liquid fires but not for chip or fat pan fires.
- Safe on electrical fires if tested appropriately.

Life-saving Appliances

Lifeboats and life rafts are crucial for emergency evacuations.
Life jackets must be bright, equipped with ropes, and stored in accessible locations.
Immersion suits protect against hypothermia and should be worn with life jackets.

Requirements and Training

Safety education is mandatory for crew members before boarding.
Regular drills for emergencies (fire, abandon ship, man overboard) are essential for preparedness.
Personal safety gear (helmets, gloves, safety shoes) is required during daily operations.

Tanker Safety Measures

Additional fire systems may be implemented, such as foam coverage on decks.
Markings indicating escape routes and safety gear are essential for quick access.

Global Maritime Distress and Safety System (GMDSS)

GMDSS enhances communication safety at sea with specialized equipment.
EPIRBs (Emergency Position Indicating Radio Beacons) provide distress signals, often with GPS capabilities.

Pyrotechnics

Red parachute signals provide visual alerts and can be seen from far away.
Smoke signals produce thick orange smoke, useful for location visibility.
Line throwing apparatus enables quick connection to another vessel for rescue or towing.

Conclusion

Proper understanding of safety protocols, equipment types, and emergency procedures is essential for maritime safety.
