UNIT – I – PHYSICS AND CHEMISTRY OF FIRE

Fire properties of solid, liquid and gases, fire spread, toxicity of products of combustion, theory of combustion and explosion – vapor clouds – flash fire- jet fires – pool fires – unconfirmed vapor cloud explosion, shock waves, auto ignition, boiling liquid expanding vapor explosion – case studies.

UNIT – II – FIRE PREVENTION AND FIRE FIGHTING

Sources of ignition – fire triangle – principles of fire extinguishing – active and passive fire protection systems – various classes of fires – A, B, C, D, E, F – types of fire extinguishers – fire stoppers – hydrant pipes – hoses – monitors – fire watchers – layout of stand pipes – fire station – fire alarms and sirens – maintenance of fire trucks – foam generators – escape from rescue operations – fire drills – notice – first aid for burns.

UNIT – III – FIRE PROTECTION SYSTEMS

Sprinkler – hydrants stand pipes – special fire suppression systems like deluge and emulsifier – selection criteria of the above installations – reliability – maintenance – evaluation and standards – alarm and detection systems – other suppression systems – co2 system – foam system – dry chemical powder (DCP) system – halon system – need for halon replacement – smoke venting – portable extinguishers – flammable liquids – tank farms – indices of inflammability – firefighting systems.

UNIT – IV – FIRE SAFETY IN BUILDINGS

Fire load, fire resistant material and fire testing – structural fire protection – structural integrity – exists and egress –fire certificates – fire safety requirements for high rise buildings – snookers.

UNIT – V – SYSTEMS TO PROTECT BUILDING EXPLOSIONS

Principles of explosion – detonation and blast waves – explosion parameters – explosion venting – inter gases for generation of inert gas – rupture disc in process vessels and lines explosion. Suppression system based on carbon dioxide (CO2) and halons – hazards in LPG, ammonia (NH3), sulphur dioxide (SO3), chlorine (cl2) etc. Indian explosives act and rules – static and mobile pressure vessel (SMPV) rules – Indian gas cylinders – petroleum act
