OSF351 Fire Safety Engineering Syllabus:

OSF351 Fire Safety Engineering Syllabus – Anna University Regulation 2021

COURSE OBJECTIVES

 To enable the students to acquire knowledge of Fire and Safety Studies
 To learn about the effect of fire on materials used for construction, the method of test for noncombustibility & fire resistance
 To learn about fire area, fire stopped areas and different types of fire-resistant doors
 To learn about the method of fire protection of structural members and their repair due to fire damage.
 To develop safety professionals for both technical and management through systematic and quality-based study programmes

UNIT I INHERENT SAFETY CONCEPTS

Compartment fire-factors controlling fire severity, ventilation controlled and fuel controlled fires; Spread of fire in rooms, within building and between buildings. Effect of temperature on the properties of structural materials- concrete, steel, masonry and wood; Behavior of non-structural materials on fire- plastics, glass, textile fibres and other house hold materials.

UNIT II PLANT LOCATIONS

Compartment temperature-time response at pre-flashover and post flashover periods; Equivalence of fire severity of compartment fire and furnace fire; Fire resistance test on structural elementsstandard heating condition, Indian standard test method, performance criteria.

UNIT III WORKING CONDITIONS

Fire separation between building- principle of calculation of safe distance. Design principles of fire resistant walls and ceilings; Fire resistant screens- solid screens and water curtains; Local barriers; Fire stopped areas-in roof, in fire areas and in connecting structures; Fire doors- Low combustible, Non-combustible and Spark-proof doors; method of suspension of fire doors; Air-tight sealing of doors;

UNIT IV FIRE SEVERITY AND REPAIR TECHNIQUES

Fabricated fire proof boards-calcium silicate, Gypsum, Vermiculite, and Perlite boards; Fire protection of structural elements – Wooden, Steel and RCC.. Reparability of fire damaged structures Assessment of damage to concrete, steel, masonry and timber structures, Repair techniques- repair methods to reinforced concrete Columns, beams and slabs, Repair to steel structural members, Repair to masonry structures.

UNIT V WORKING AT HEIGHTS

Safe Access – Requirement for Safe Work Platforms- Stairways – Gangways and Ramps-Fall Prevention & Fall Protection – Safety Belts – Safety nets – Fall Arrestors- Working on Fragile Roofs – Work Permit Systems-Accident Case Studies.

TOTAL : 45 PERIODS
COURSE OUTCOMES

On completion of the course the student will be able to
CO1: Understand the effect of fire on materials used for construction
CO2: Understand the method of test for non-combustibility and fire resistance; and will be able to select different structural elements and their dimensions for a particular fire resistance rating of a building.
CO3: To understand the design concept of fire walls, fire screens, local barriers and fire doors and able to select them appropriately to prevent fire spread.
CO4: To decide the method of fire protection to RCC, steel, and wooden structural elements and their repair methods if damaged due to fire.
CO5: Describe the safety techniques and improve the analytical and intelligence to take the right decision at right time.
