SF3016 Explosive Technology and Safety Syllabus – Anna University Regulation 2021
OBJECTIVES
1. To teach the fundamental principles of explosives and the safety aspects of explosives operations, storage and transportation
2. To teach the fire building and its mechanisms and behaviors
3. To teach the explosive prediction and controlling elements
4. To aware of industrial fire production system and its usage
5. To learn testing and fire explosives of an industry
UNIT I PHYSICS AND CHEMISTRY OF FIRE
Chemistry of Explosives – Chemical reactions – Categories of explosives by chemical type – Use forms of Explosives, Propellants, and Pyrotechnics. Mechanics of Burning – Burning model – Geometry shape of grains.
UNIT II MECHANISM OF SOUND AND SHOCK
Sound, shock and Detonation – Sound waves – shock waves – Detonation waves – Explosive output tests. Initiation and initiators – Initiation theory and criteria – Initiation sensitivity testing -Non electric initiators – Hot-wire initiators – exploding bridge wire detonators – Slapper detonators.
UNIT III BUILDING FIRE SAFETY
Scaling in Design and Analysis – Geometric similarity – Accelerating metal with explosives -Shock waves in air – Shock waves in water – Craters from explosives – Conical – shaped chargers. Off-the – Shelf explosive Devices – Linear explosive products – Mechanical /explosive devices.
UNIT IV EXPLOSION PROTECTING SYSTEMS
“Classification, Transportation and Storage of Explosives – Explosives classification – Transportation of explosives – Storage of explosives. Explosive Facilities and Explosives Operations – Explosive facilities – Explosive operations – Goodwork practices – Maintenance – Explosive waste- Spills and general cleaning – Explosive handling.
UNIT V 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-fire fighting systems.
