2. SAFETY
The condition of being protected from or unlikely to cause danger, risk or injury.
Safety is a simple ABC of mind;
A- Attention
B- Between
C- Critical
2

3. Safety is divided in two part-
I. Occupational Health and Safety
II. Hygiene Safety
3

4. OCCUPATIONAL HEALTH SAFETY
It is also divided in many part like;
I. Fire Safety
II. LAB Safety
III. Construction Safety
IV. Mining Safety
V. Port Safety
VI. Radiation Safety
VII.Clinical Safety
4

5. HYGIENE SAFETY
I. Food Safety
II. Product Safety
III. Waste Material Management
5

6. FIRE SAFETY
Fire is the release of heat and light from rapid combination of oxygen and
other materials.
Or
Fire is oxidation process that produces Heat and light.
Fuel +Oxygen +Energy Fire(Light +Heat +Products of combustion)
Stages of Fire-
I. Incipient Stage
II. Smoldering Stage
III. Flame Stage
IV. Heat Stage

7. CLASSIFICATION OF FIRE
Class A- Solid( Paper, Wood)
Class B- Liquid(Low Boiling Point Liquid, Vapour)
Class C- Gas(Highly Reactive) .
Class D- Metals(Lead, Nickle)
Class E- Electrical(Electrical Equipment)
Class K- Kitchen(Home)

8. EXTINGUISHING OF FIRE
I. Starvation- Limitation of Combusting material
II. Smothering- Limitation of Oxygen
III. Cooling- Limitation of Temperature

10. FIRE PROTECTION
There are three goal of Fire Protection;
I. Life Safety
II. Property Protection
III. Continuity Of Operation
Fire Protection System-
I. Passive Protection
II. Active Protection
10

11. PASSIVE PROTECTION
I. Fire proof doors
II. Fire proof walls
III. Wired glass window
IV. Dampers protection of cable wires
V. Fire proofing material
11

12. ACTIVE PROTECTION
I. Fixed System
II. Portable Extinguishers
Fixed System-
I. Water Hydrant System
II. Foam System
III. Dry Chemical Powder System
IV. CO2 System
V. Steam System
VI. Sprinkler System

13. PORTABLE EXTINGUISHERS
CO2 Foam Powder Water Halon
13

14. CO 𝟐 TYPE EXTINGUISHERS
It is used on B and C class Fire so its also called BC, CO2 type Extinguisher.
Discharge time and Distance;
2 Kg- 10 sec , 1-1.5 m
5 Kg- 20 sec , 2-4 m
14

15. FOAM TYPE
It contain Mechanical Foam and it is used on A and B type Fire.
Foams are; Discharge time and Distance;
I. AFFF I. 3 lit- 10 sec,3-4 m
II. AR-AFFF II.9 lit- 40 sec,4-6 m
III. FFFP
IV. CAFS
V. Fire Ade
VI. Wet chemical
15

16. POWDER TYPE
It contain dry chemical powder and divided in
two type;
ABC type- It used on A,B and C type Fires and it
contain Monoammonium Phosphate.
BC type- It used on B and C type Fires and it
contain Sodium and Potassium Bicarbonate.
Discharge time and Distance;
I. 1 Kg- 7 sec, 2m
II. 4 Kg- 11sec, 4m
III.9 Kg- 18sec, 8m
16

17. WATER TYPE
It contain only water and compressed gas and it used only on class A.
It is also three type;
I. APW These two type are generally used.
II. Water Mist
III. Soda Acid Type
Discharge Time And Distance;
I. 3 Lit -10 sec, 5 m
II. 9 Lit -55 sec, 8 m
17

18. HALON TYPE
It contain a gas that interrupts the chemical reaction. It used on D type fire
and it widely used in Aircraft .
There two type;
I. Halon 1121
II. Halotron I
III. FE-36 (HFC-36fa) Presently these two are used.

19. HYDRANT SYSTEM
A Hydrant system is a network of pipe distributed throughout the protected
area and charged with water.
I. Wet Hydrant System
II. Dry Hydrant System
19

20. DRY HYDRANT SYSTEM
It is unpressurised hydrant
system.
This type of hydrant system
are used where the winter
temperature fall below
0℃ it contain;
I. Main Pump
II. Diesel Engine Pump
20

21. WET HYDRANT SYSTEM
It is pressurized Hydrant
system.
Generally this type of
system are available in
where winter temperature
above 10℃ it contain;
I. Jockey Pump
II. Main Pump
III. Diesel Engine Pump
21

22. SPRINKLER SYSTEM
I. Water sprinkler
II. CO2 sprinkler
Water Type CO2 Type
Wall Type 22
