Which of the following is a common cause of galley fires?

Rubbish accumulation is a common cause of galley fires, primarily because it creates a bedding of flammable materials that can ignite from sparks or heat sources present in the cooking environment. In a galley, where various cooking processes take place, it is essential to maintain cleanliness and proper waste disposal to prevent the buildup of combustible debris. Food residues, packaging materials, and unused supplies can easily ignite if they come into contact with a flame or hot surface, leading to potentially dangerous fire situations.

While other factors like exposed wiring, faulty equipment, and smoking indoors can be fire hazards in general, rubbish accumulation specifically poses a unique risk in the galley area due to the combination of heat, oil, and other combustible materials present. Maintaining a clean and well-organized working environment is thus crucial for fire prevention in such high-risk areas.
