The document discusses various fire safety techniques, including controlling air flow to limit fire spread, entry techniques for firefighters, and restoring essential ventilation after a fire. It emphasizes the importance of immediately stopping all ventilation to contain smoke and prevent air supply to the fire. Proper ventilation control, entry procedures, and post-fire checks are described as key to effectively battling fires and limiting damage.

LESSON 5
CONTROL OF AIR FLOW
VENTILATION CONTROL: FLOW OF AIR WILL HELP THE FIRE. TO ACHIVE THE
AIM OF REDUCING THE FLOW OF AIR TO A ROOM AND LIMIT THE SPREAD
OF SMOKE, IN THE SHORTEST POSSIBLE TIME, THE STANDARD PROCEDURE
IS
CRASH STOPPING ALL VENTILATION FANS (BLOWERS / EXHAUSTS) AS SOON
AS THE ALARM IS RAISED THIS ACTION SIGNIFICANTLY CONTRIBUTES
TOWARDS REDUCING THE SUPPLY OF AIR TO THE FIRE PREVENTS THE
SMOKE FROM SPREADING
National Safety Academy

3. National Safety Academy dgfdghfdh
a) RESTORING POWER TO ALL VENTILATION SYSTEMS SO THAT THEY MAY
BE RESTARTED
b) SUPPLY VENTILATION IS ESSENTIAL SYSTEM AND ROOMS NOT
AFFECTED BY FIRE
d) CONTAIN THE SMOKE WITHIN THE DESIREED BOUNDARY AND PREVENT
THE SUPPLY OF AIR TO THE FIRE
e) REMOVE SMOKE FROM ARTEAS ADJACENT TOP THE FIRE AND REMOVE
ALL SMOKE AND FURNES AFTER EXTINCTION
National Safety Academy

4. National Safety Academy dgfdghfdh
CRASH STOPPING VENTILATION:
a) SHUT DOWN MAIN POWER SUPPLY IMMEDIATEDLY TO WHOLE AREAS
OF INDUSTRY. SWITCH ON NECESSARY LIOGHTING POWER SUPPLY AT
THE SWITCH BOARD AFTER FIVE SECONDS.
b) TRIP THE LOCAL STARTERS OF GENERAL VENTILATIONS FANS WHICH
ARE NOT CONTROLLED FROM VENTRILATION BREAKERS
c) IF INDUSTRY IS PROVIDED WITH CENTRALIZED AIR CONDITIONED AIR
SUPPLY IT HAS BE CONTROLLED AT VENTILSTION TRUNKING
d) ELECTRICAL SIPPLIES MUST BE AVAILABLE TO ALL VENTILATION
SYSTEMS AS SOON AS POSSIBLE AFTER CRASH STOPPING SO THAT
SYSTEMS ESSENTIAL AND WHICH DO NOT INTREFERE
National Safety Academy

5. National Safety Academy dgfdghfdh
e) CARE MUST BE TAKEN THAT SMOKE IS NOT PICKES UP BY SUCTIONS
OF HP AIR COMPRESSOR AND BY ESSENTIALS SYSTEMS TO LIVING
SPACES
f) BOUNDARIES MUST BE ESTABLISHED TO ENSURE THAT SMOKE IS
CONTAINED
g) WHEN USING EXHAUST FANS A ROUTE TOP ATMOSPHERE MUST BE
OPENED UP TO ALLOW MAKE UP AIR TYO ENTER INSIDE
MACHINERY SPACE VENTILATION:
a) CLOSE THE VENTILATION SUPPLY FLAPS TO THE MACHINERY SPACE
AFFECTED
b) STAND BY TOP CLOSE VENTILATION EXHAUST FLAPS, BUT DO NOT
CLOSE UNTOL ORDERED, SO THAT THE EXHAUST SYSTEM CAN BE
CONTINUE TO BE USED FOR THE FIRST AID FIRE FIGHTING

HANDLE IT?
i. HOW TO CONTROL VENTILATION SUPPLT TO THE FIRE?
j. ARE ANY DANGEROUS GASES OR VAPOUR PRESENT?
k. IS BREATHING APPARATUS NECESSARY?

REMOVED FROM CONTACT WITH ROOMS?
l. DO BOUYNDARIES REQUIRE TO BE COOLED? SHOULD MEN
EQUIPMENT BE MADE READY FOR COOLING? ARE THE BOUNDARIES

METAL(ALUMINIUM)
m. WILL THE SPRAYING OF WATER WILL ADD MORE TROUBLE AND
NECESSARY?
n. IS SMKE PRESENT IN SUCH A MANNER AS TO GIVE FALSE IMPRESSION
OF THE SEAT OF THE FIRE ?

o. HAS VENTILATION BEEN CRASH STOPPED? IF FIRE CURTAINS ARE
REQUIRED HAVE THEY BEEN USED?
p. HAS CONTROL ROOM/ MANIN GATE BEEN ADVISED OF THE
SITUATION?
q. ARE ANY MORE APPLIANCES REQUIRED FROM OTHER PARTS OF THE
INDUSTRY? WILL MORE MEN BE REQUIRED?
r. HAS THE STABLITY OF THE VESSELS (FLOATING VESSELS)BEEN
CONSIDERED? HAS PROVISION BEENM MADE FOR PUMPING OUT OR
DRAINING DOWN FIRE FIGHTING WATER?
s. DO ANY ELECTRICAL CIRCUITS NEED TO BE BROKEN? DO THEY SUPPLY
ANY ESSENTIAL SERVICES? SHOULD ELECTRICAL EQUIPTMENT BE
COVERED?
t. SHOULD A REQUEST BE MADE TO THE CONTROL ROOM FOR ANY
SPECIAL EQUIPTMENT?
National Safety Academy

11. National Safety Academy dgfdghfdh
AFTER FIRE CONTROL:
CAN THE ROOM BE OPENED FOR INSPECTION?
IS IT SAFE TO RESTART VENTILATION TO THE ROOM?
CAN THE EQUIPTMENT IN ROOM BE STARTED
IS IT THE FIRE REAKKY EXTINGUISHING OUT ? IS ANY THING STILL
SMOLDERING?
CAN ANY REMAINING SMOKE BE DISPERSED BY RUNNING THE EXHAUST
FANS?
IS THERE ANY DANGER OF SPONTANEOUS RE IGNITION ? CAN THE DANGER
BE PREVENTED?
HAS A SENTRY BEEN POSTED?
WHAT DAMAGE IS THERE TO ELECTRICAL FITTINGS?

ENTRY THROUGH:
ENTRY THROUGH DOOR:
 THEY MUST TIE ONE WIRE ROPE ON THE HANDLE OF THE DOOR, IF DOOR
IS VERY HOT. THE ROPE HELPS THEM TO CLOSE THE DOOR IMMEEDIATEDLY
THEY SHOULD NOT STAND IN THE MOVING AREA OF THE DOOR. IF THE
PRESSURE OF THE ROOM IS MORE, THE DOOR WILL BANG ON THEM
BOTH WATER WALL MAKER AND FIRE FIGHTTER WILL KEEP THEIR NOZZLES
AT THE WATER WALL POSITION
BOTH SHOULD TAKE POSITON AT THE OPENING SIDE DOOR ( OPPOSITE
SIDE OF HANGERS)
GROUP LEADERS POSITIONS HIMSELF BEHIND THE FIGHTERS AND CALLS
FOR THE WATER TOP BE TURNED ON.

ENTRY THROUGH WINDOW:
a) THE WINDOW NEAR TO FIRE IS TO BE CAREFULLY SELECTED FOR
OPENING AFTER CONSIDERED HEIGHT CITTING AND WIND DIRECTION
b) WITH THE HELP OF CUTTING MACHINES REQUIRED SIZE IS TO BE CUT
AND OPENED FOR ENTRY
c. WATER WALL AND FIRE FIGHTERS TAKES UP POSITION. THE NOZZLES
ARE POSITIONED AT THE OPENING
d. LEADER INSTRUCTS WAYTER WALL OPERATOR AND FIRE FIGHTER TO
SET THEIR NOZZLES AT THE WATER WALL POSIOTON AND INSTRUCTS
HISES TENDER TO OPEN VALUE
e. BOTH WATER WALL OPEARTOR AND FIRE FIGHTER ENTERS INSIDE
FOLLOWED BY LEADER
f. LEADER LOOKSS THROUGH THERMALK IMAGING CAMERA AND
INSTRUCTS FIRE FIGHTER

IMPORTANT POINTS
a) BASIC TACTICS OR FIGHTING A FIRE ARE RESCUE OPERATIONS,
PROTECTIONS OF AREAS EXPOSED TO FIRE, CONFINEMENT OF THE
FIRE, EXTINGUING THE FIRE AND SALVAGE OPEARTIONS.
b) COMPLICATED SITUATIONS ARISE WHEN MORE THAN ONE ROOM AND
A VARIETY OF MATREIAL ARE INVOLVED OR THREATENED

FIRE FIRE FIRE
SMOKE CLEARANCE IS ONLY UNDERTAKEN WHEN A
FIRE IS EXTINGUISED
AREAS ARE TO BE CLASSIFIED ACCORDING TO THE FIRE RISK INVOLVED
ON SLIGHTEST SUSPECION OF ANY TRAPPED PERSONNEL INA SMOKE
FILLED ROOM SEARCH SHOULD BE STARTED IMMEDIATEDLY BY PERSONNEL
IN PAIRS
FLAME SMOKE HEAT DARKNESS AND STRUCTURAL DAMAGE MAY HIONDER
THE FIRE FIGHTER IN GETTING TO THER SEAT OF A FIRE
WITH THE AID OF BREATHING APPARATUS AND GOOD AREA KNOWLEDGE
SMOKE SHOULD NOT BE PROBLEM FOR FIGHTER
National Safety Academy

16. National Safety Academy dgfdghfdh
PROPER CAUTION AND GUIDELINES SHOULD BE FOLLOWED IN OPENING A
DOOR AND WINDOW OF A ROOM CONTAINING FIRE
A SERIOUS FIRE CANNOT BE EFFECTIVELY CONTROLLED UNLESS THERE IS
SYSTEMATICALLY APPROACH TOI FIRE FIGHTING
INDUSTRIES ARE TO BE RAISED EMERGENCY CARD FOR ALL RISK AREAS
PRIOR TO ENTRY IN COMPARTMENT THE HOSES ARE NOT TO BE CHARGED
EFFECTIVE CONTROL OF VENTILATION CAN BE ACHIEVED IN STAGES
BOUNDARY COOLING CONTAINS A FIRE WITHIN THE SMALLEST POSSIBLE
AREA BY KEEPING THE ADJOINING WALLS AND ROOFS COOLED WITH
WATER SPRAY
