Electronic industry class clean plant particularity and fire risk,
building fire protection design should pay attention to the following
six points:
First, fire water supply and fire fighting equipment
1,
clean room production layer and the upper and lower technology plus
layer (excluding non-access to the technical sandwich), should be set up
indoor fire hydrant. Fire hydrant water consumption of not less than 10L / s, each water gun water should be not less than 5L / s.
2, clean plant with precious equipment, equipment, rooms should be set up a fixed fire fighting facilities. When setting up automatic sprinkler system, it is advisable to use
pre-acting automatic sprinkler system. When setting up gas fire
extinguishing system, it should not use fire extinguishing agent which
can cause suffocation and secondary damage to the protection object.
Second, fire communication facilities
As a result of a large number of clean room indoor use of metal sheet, the general shielding effect is very strong. So in the clean room should be set up a complete set of fire communication facilities. This
facility is not only used by internal workers in the event of a fire
alarm and communication, but should also be used by fire officers and
soldiers involved in fire fighting to ensure that fire communication is
smooth and that unnecessary communication interruption and communication
failures are reduced to ensure the safety of firefighters The
Third, fire separation
1, clean plant fire rating should not be lower than two.
2,
clean plant floor number to determine: due to process requirements, the
level of clean room is generally higher than the average plant, and the
need to set up and down the technical sandwich or technical lanes,
mezzanine set some equipment, fans, ducts, cables, Of the pipeline. It is connected with the clean area by the hollow floor, ceiling or complex pipe connected up and down. If the technical sandwich as a separate layer, fire separation is
obviously very difficult, I learn from the views of experts that the
upper and lower technical mezzanine and production areas as a layer to
consider, but should be set up in the upper and lower mezzanine
corresponding fire facilities.
3, clean the plant's fire partition. As
the process needs, production workshop production line length of 200
meters, in accordance with the "civil building design fire safety
regulations," the requirements of the fire partition is completely
unrealistic. In view of the small number of employees in such industries, if the
safety evacuation conditions and fire extinguishing facilities are
installed, fire prevention zones can be set up according to production
requirements.
Fourth, the safe evacuation channel
1,
safe exit and evacuation channel: In the clean plant design, the staff
of the safe evacuation is particularly important, but also more complex. Should
be in accordance with the "clean plant design specifications"
requirements of each production layer, each fire zone or the number of
safe areas of each clean area should not be less than two, and the
safety of exports should be scattered layout. Design should try to separate the evacuation route and process to meet
the production site from any one to the safe exit without twists and
turns of personnel purification path, should be clear to avoid twists
and turns, and embarked on a clear indication of the set.
2,
the requirements of the fire to save the entrance: the clean room is a
closed room, in the event of a fire, to the firefighters to save the
difficulties, so the requirements of the clean room should be provided
for the firefighters to the clean room cleaning area dedicated fire Mouth,
fire mouth spacing of not more than 80m, the width should not be less
than 750mm, the height of not less than 1900mm, there should be a clear
sign, the fire can usually be closed, the use of firefighters from the
outdoor open. Designed in the factory fire fighting door should be set up in the
staircase or evacuation walkway, to ensure the safety of firefighters
themselves.
Fifth, ventilation and smoke control
1, flammable, explosive area of the exhaust should be separated from
the general area, set up separately, and select the explosion-proof
exhaust fan.
2, in order to ensure the safety of production and staff safety, should set the accident exhaust system. The exhaust system should be equipped with automatic and manual
control switch, manual control switch should be located in the clean
room and clean outdoor easy to operate the location.
3, clean the corridor of the plant, should be set up mechanical smoke control facilities. Clean the plant more types of pipelines, if a set of smoke prevention
and drainage pipe has a great difficulty, clean room mechanical smoke
system can be ventilated, clean air conditioning system combined, but
must take a reliable fire safety measures.
4, the duct should be non-combustible materials, and in accordance
with the requirements of the relevant specifications set fire valve.
Sixth, electrical
1, clean plant should be set for personnel evacuation with emergency lighting and evacuation signs. In the fire mouth should be set to red emergency lights.
2, clean plant should be set aside to meet the needs of the premises
or parts of the activities and work required for the minimum
illumination, generally should not be less than the normal illumination
of the standard 1/10.
3, clean plant production area (including technical mezzanine), room, station, etc. should be set fire alarm detector. Clean plant production area and corridor should be set to manual fire alarm button.
4,
clean room may produce electrostatic hazards of equipment, mobile
liquid, gas or powder pipeline should take anti-static grounding
measures.
