19 knowledge points of fire safety inspection should be mastered by property owners.

Inspection of (I) fire sources

1. Open flame

Match flame, lighter flame, candle flame, alcohol blowtorch flame, stove flame, gas welding and gas cutting (2 persons)

2. High temperature objects

Iron chimney, engine exhaust pipe, fire pit, fire wall, electric furnace and resistance, incandescent lamp, iodine tungsten lamp, steam boiler, cigarette end, welding arc slag (arc 1 person, arc is electric spark)

3. Electric spark

Electrical switch on or off spark, short circuit spark, lightning, relay spark

4. Impact and friction sparks

Machining friction sparks

5. Light irradiation and gathering

Sunlight stove, convex lens

6. Exothermic chemical reaction

(II) fire door

1. Material of fire door: steel, wood, steel wood, etc.

Grade: Grade A ≥ 1.5h, Grade B ≥ 1.0h, Grade C ≥ 0.5h

2. Fire door status: normally open and normally closed.

3, the difference between the normally open fire door and the normally closed fire door: the normally open fire door has a release and the normally closed fire door does not.

4. Closing method of normally open fire door

① Fire control room remote control off

② Local closing

5, fire door reset operation: fire control room fire alarm controller fire door signal reset site manual fire door reset.

6. The function of the door closer: close the fire door.

The function of the releaser: release the normally open fire door, and then close it by the pulling force of the door closer.

The role of the sequencer: to ensure that the double fire doors are closed in sequence.

7. Self-inspection of fire door

① Whether the door frame, door leaf, door closer and other parts of the fire door are intact

② Whether the release device is sensitive when the normally open fire door is closed, whether the double normally open fire doors are closed in sequence, and whether the normally closed fire doors can be closed automatically.

Whether the fire door is closed, whether it has a good fire and smoke isolation effect.

④ Trigger two related fire detectors to see the closing effect and feedback signal of the normally open fire door.

8. Key points of fire door inspection

① Whether the door frame, door leaf, door closer and other parts of the fire door are intact.

② Whether the release device is sensitive when the normally open fire door is closed, whether the double normally open fire doors are closed in sequence, and whether the normally closed fire doors can be closed automatically.

Whether the fire door is closed, whether it has a good fire and smoke isolation effect.

④ Whether sundries are piled up in front of the fire door.

(III) fire shutter

1. Fire resistance rating: ordinary steel fire shutter ≥ 2h, composite steel fire shutter ≥ 3h, super fire shutter ≥ 4h.

2, two-step drop and one-step drop fire shutter installation site:

The two-step descent is installed on the evacuation passage, and the one-step descent is installed in the fire compartment, around the non-evacuation passage and the escalator.

3. Installation position of two-step smoke and temperature reduction: a group of smoke and temperature detectors located within 3.0 meters on both sides (or one side) of the fire shutter.

4. Self-inspection of fire shutter

① Manual operation method

② Electric operation method

③ Two-step drop triggers smoke and temperature respectively

The fire control room output remote control signal.

5. Inspection of rolling shutter door

① Whether the control panel and door body of the fire shutter are intact.

② Whether the smoke and temperature corresponding to the two-step fire shutter are intact.

③ Whether sundries are piled up under the fire shutter

Whether the fire shutter is in the normal rising state

6. Contents of fire prevention inspection

① Whether there is any violation of regulations in the use of fire and electricity

② Whether fire-fighting facilities, equipment and fire safety signs are in place and complete.

Whether the normally closed fire door is closed, whether the goods are stacked under the fire shutter.

④ Whether the safety exit and evacuation passage are unobstructed, and whether the safety evacuation indicator light and emergency lighting are in good condition

⑤ On-duty situation of personnel in key parts of fire safety.

Other fire safety conditions.
