The document discusses fire safety in schools, including the chemistry and growth of fires, fire classifications, fire extinguishers, and rescue procedures. It explains that fire is a chemical reaction that requires fuel, oxygen, and heat. Fires progress through incipient, smoking, flame, and heat stages as they grow. Methods to extinguish fires include starvation, blanketing, and cooling. Portable fire extinguishers use various media like water, foam, dry chemical powder, and carbon dioxide. Proper fire extinguisher use follows the PASS method of pull, aim, squeeze, sweep. Precautions after escaping a fire include sealing cracks and covering vents. Rescue procedures involve feeling doors and openings for heat before entering

2. CHEMISTRY OF FIRE
Fire is a chemical reaction in which the substance(fuel)
combines with oxygen and heat giving rise to fire

• INCIPIENT STAGE - NO VISIBLE SMOKE
• SMOKING STAGE- VISIBLE SMOKE
• FLAME STAGE – FLAME STARTS, SMOKE

24. How to use
Fire
Extinguishers?

25. Remember the acronym PASS:
How to Use a Fire Extinguisher
Pull
Aim
Squeeze
Sweep

26. Pull the pin…
How to Use a Fire Extinguisher
This will allow
you to discharge
the extinguisher

27. Aim at the base of the fire…
How to Use a Fire Extinguisher
Hit the fuel.
If you aim at the flames...
… the extinguishing agent will fly right
through and do no good.

28. Squeeze the top handle…
How to Use a Fire Extinguisher
This depresses a
button that
releases the
pressurized
extinguishing
agent.

29. Sweep from side to side…
How to Use a Fire Extinguisher
.. until the fire is
completely out.
Start using the extinguisher from a
safe distance away, then slowly
move forward.
Once the fire is out, keep an eye
on the area in case it re-ignites.

31. How will you come out of
the room?
If you are trapped in smoke or heat

32. Coming out of the room in fire/smoke

33. What precaution will
you take after coming
out of the room to
contain fire?
If you are trapped in smoke or heat

34. Stuff the cracks around doors with
towels, rags, clothing or tape, and
cover vents to keep out smoke
Precaution after coming out of the room

35.  If feasible, call fire department
to tell your exact location.
