Study Notes

Fire Hazards

A fire is a combustion or burning that releases bright light, heat, and smoke when substances combine with oxygen from the air.
Fire can be useful, but it also has negative effects, including hazards to life and property, atmospheric pollution, and water contamination.

Causes of Fire

Electrical faults, such as faulty appliances, leads, wiring, or sockets
Cooking-related fires, such as burnt food, unattended cooking, or grease build-up
Flammable and combustible materials, incorrect storage, usage, or disposal
Smoking, such as smoking around flammable materials or disposing of cigarette butts improperly
Heating, such as placing articles too close to heat sources or using faulty heaters

Stages of Fire

Incipient: the developing or embryonic stage of fire, characterized by low heat, minimal smoke, and ease of escape
Growth: the stage where the fire has established itself, generating heat and using fuel sources
Fully Developed: the hottest and most ferocious stage, where the fire has engulfed all available fuel sources
Decay: the longest stage, where the fire runs out of oxygen or fuel, but can still reignite with new oxygen or fuel sources

Effects of Fire Hazards

Acute and chronic effects on human health, including respiratory and cardiovascular symptoms, burns, trauma, mental health effects, reproductive and immunological disorders, and social and financial disruption
Environmental impacts, including smoke, water, sediment, and soil pollution, increased erosion, habitat degradation, and releasing large quantities of carbon dioxide and fine particulate matter

Fire Safety Measures

Preventing fire by isolating sources of fuel or heat, as a fire needs three elements to ignite and maintain combustion: fuel, heat, and oxygen
Top 10 fire prevention tips, including:
- Avoiding electrical overloading
- Fireproofing the kitchen
- Keeping light sources secured
- Practicing good housekeeping habits
- Installing smoke alarms
- Having a fire extinguisher
