CPC331 Fire and Explosion Control Syllabus:
CPC331 Fire and Explosion Control Syllabus – Anna University Regulation 2021
OBJECTIVE
To gain knowledge on BLEVE vapour cloud explosion.
To learn about principles of fire extinguishers.
To gain knowledge on industrial fire protection systems.
To learn about the fire protection and fire safety equipment.
To Gain knowledge on explosive control.
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 – vapour clouds – flash fire – jet fires – pool fires – unconfined vapour cloud explosion, shock waves – auto-ignition – boiling liquid expanding vapour explosion – case studies – Flixborough, Mexico disaster, Pasedena Texas, Piper Alpha, Bombay Victoria dock ship explosions, Mahul refinery explosion, Nagothanevapour cloud explosion and Vizag refinery disaster.
UNIT II FIRE PREVENTION AND PROTECTION
Sources of ignition – fire triangle Fire Tetrahedron – principles of fire extinguishing – active and passive fire protection systems – various classes of fires – A, B, C, D, E-Fire extinguishing agentsWater ,Foam, Dry chemical powder, Carbon-dioxide- Halon alternatives Halocarbon compoundsInert gases , dry powders – types of fire extinguishers – fire stoppers – hydrant pipes – hoses – monitors – fire watchers – lay out of stand pipes – fire station-fire alarms and sirens – maintenance of fire trucks – foam generators – escape from fire rescue operations – fire drills – notice-first aid for burns.
UNIT III INDUSTRIAL 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 BUILDING FIRE SAFETY
Objectives of fire safe building design, Fire load, fire resistant material and fire testing – structural fire protection – structural integrity – concept of egress design – exit – width calculations – fire certificates – fire safety requirements for high rise buildings.
UNIT V EXPLOSION PROTECTING SYSTEMS
Principles of explosion-detonation and blast waves-explosion parameters – Explosion Protection, Containment, Flame Arrestors, isolation, suppression, venting, explosion relief of large enclosureexplosion venting-inert gases, plant 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).
TOTAL: 45 PERIODS
