Fire Hazard leads to loss of lives and properties and many more.
Not only hundreds; thousands of people in the world die due to fire hazards.
It also damages the structure and fails concrete too. Some of the effects of fire on concrete are shown below.
Subjecting of concrete to high temperature causes the spalling of concrete. Effects of temperature on concrete are:
100 deg. C = No effect or negligible
200 – 250 deg.C = 25% Loss in efficiency
500 – 600 deg. C = Completely loss of efficiency
2. Causes of Fire Hazard
Some causes of fire hazards in buildings are:
1. Combustion of combustible material
2. Due to underground electric table
3. Building fire from bone fire
4. Electric short circuit
5. Due to electric appliances like heating of air condensing
6. Storage of combustible chemical and flammable liquid
7. Due to lightning
8. Due to smoking
3. Effects of Fire Hazard
Some of the effects of fire hazards in buildings are:
1. Production and release of toxic gases
2. Destruction of water supply and electric supply system
3. Combustion and damage of timber structure and flammable material in a building like a furniture, roof, paper, clothes, etc.
4. Injury to humans and animals
5. Loss of important properties, documents, foods, or lives
6. Environmental pollution and an increase in global temperature
4. Remedial Measures
Some remedial measures of fire hazards in buildings are:
1. Collecting waste paper in a tight-fitting metal container
2. Store important paper in a fire-resistant safe cage
3. Do not store electric appliances near the electric circuit
4. Do not store flammable liquid for a chemical if unavoidable store in a safe cage only
5. Install fire safety measures on a building to reduce fire risk
6. Treat the combustible material with a fire retardant chemical to reduce the chance of ignition
7. Prevent smoky area
8. Install a proper fire alarm system
9. Public awareness
In this way, there may be many more causes, effects, and remedial measures of fire hazards.
