LIST DOWN SUBSTANCES PRESENT IN FIRE?- carbon & Hz- 02, polymer- CO (due to insuffrcient O2 duringJire)- COz, HzO, smokeWHAT DOES AUTO-IGNITION MEAN?A temperutare in which fuel will self-ignite even with no ignition source

WHAT IS FLAMMABLE RANGE/EXPLOSIVE RANGE?Refer to concentration offuel vapor in air that cun ignite by ignition sourceWHAT IS FLASH POINT?Refer lo the lowest temperature in which fuel can prodace safftcient vapor to tlash in thepresence of ignition sourceWHAT IS FIRE POINT?

Refer to the minimum temperaturc where the vapors from the fuel will continue to burn givensoutce of ignition.HOW TO PREVENT FIRE?by breaking the Jire triangle whether remove fuel starve the ftre ot even lower the combustionpointLIST DOWN METHOD TO PREVENT FIRE?- good hoase keeping -->propet storuge- designfor safety --->get lessflammable stuff- ltre detection -->s!stem lo wam asDESCRIBE 4 FIRE DETECTION SYSTEM?I )thermal expansion detectorso use heat sensitive metsl linko it will melt at a predetermined T to mske contacto and sound the alarm
