Which of these activities could present a fire risk in a residential property?

All of the activities listed—using a space heater, smoking, and cooking—can potentially present a fire risk in a residential property.

When using a space heater, improper placement or a malfunction can lead to overheating or igniting nearby flammable materials. This is especially concerning if the heater is left unattended or if the heating element comes in contact with combustible items such as paper, clothing, or furniture.

Smoking also poses a significant fire risk, particularly if cigarettes or other smoking materials are disposed of improperly. They can ignite flammable surfaces, and the risk increases in environments where materials that can catch fire are present.

Cooking is widely recognized as one of the leading causes of residential fires. Unattended cooking, grease fires, and malfunctions in cooking appliances can quickly escalate into dangerous situations, making kitchens critical areas for fire safety precautions.

Given that each of these activities can independently lead to fire hazards, it is crucial to recognize the combined potential for danger, supporting the conclusion that all these scenarios could contribute to fire risks in a residential setting.
