5. Answer the following questions:

1. What was fire used for in the past?

2. Why was fire an essential part of human existence?

3. Why is the way that fire behaves and spreads so dangerous?

4. What factors are required for a fire to occur?

5. What is direct burning?

6. In what way can heat generated from a fire travel?

7. Why is fire a potential threat to human life and property?

6. Match Part 1 with Part 2.

The National Fire Protection Association (NFPA) classifies fires into five general categories (U.S.):

Part 1

Part 2

Class A fires

a) because of the risk of electrical shock unless a specialized water mist extinguisher is used.

Class B fires

b) involve combustible metals, such as magnesium, titanium, potassium and sodium as well as pyrophoric organometallic reagents. These materials burn at high temperatures and will react violently with water, air, and/or other chemicals. Handle with care!!

Class C fires

c) ordinary materials like burning paper, lumber, cardboard, plastics etc.

involve flammable or combustible liquids such as gasoline, kerosene, and common organic solvents used in the laboratory.

Class D fires

d) kitchen fires. This class was added to the NFPA portable extinguishers Standard 10 in 1998. Kitchen extinguishers installed before June 30, 1998 are "grandfathered" into the standard.

Class K fires

e) involve energized electrical equipment, such as appliances, switches, panel boxes, power tools, hot plates and stirrers. Water can be a dangerous extinguishing medium for class

Text 2 fire protection engineering

1. Look through the texts below and define the main areas of fire protection engineering application.

2. Choose one of the applications find out more information at home and inform your groupmates on this application.

Fire safety engineering is multidisciplinary in nature, having substantial relationships with building services, mechanical, electrical, electronics, chemical, structural and civil engineering and embraces an understanding of human behavior, based on a scientific appreciation of the fire phenomenon, of the effects of fire and of the reaction and behavior of people in order to: save life, protect property and preserve the environment and heritage from destructive fire; quantify the hazards and risk of fire and its effects; mitigate fire damage by proper design, construction, arrangement and use of buildings, materials, structures, industrial processes and transportation systems; evaluate analytically the optimum protective and preventive measures, including design, installation and maintenance of active and passive fire and life safety systems, necessary to limit, within prescribed levels, the consequences of fire.

The discipline of fire protection engineering includes:

  • Active fire protection - fire suppression systems, and fire alarm.

  • Passive fire protection - fire and smoke barriers, space separation

  • Smoke control and management

  • Escape facilities- Emergency exits, Fire lifts etc.

  • Building design, layout, and space planning

  • Fire prevention programs

  • Fire dynamics and fire modeling

  • Human behavior during fire events

  • Risk analysis, including economic factors

  • Wildfire Management.
