The earth near the underground facilities, should be gently mining, prohibit the use of grab machine tools.
It has crossed construction scheme according to the diagram
The road construction work has been reported; transportation, fire control, scheduling, safety supervision and management department
2, risk analysis: the collapse occurred
Safety measures:
The people at the same time digging should keep a safe distance.
The excavation should be from top to bottom, not by digging anchor way, dug out of the earth are not allowed to clog the sewer and manhole.
Excavation without slope ditch, pit and other must be set up support, before excavation, try to exclude surface water, when the underground water level to dig below, it is necessary to take drainage measures.
The slope has been processed and wall support.
The operating personnel must wear a helmet. The upper edge of the pit, the trough, the well and the ditch is not allowed to stand and walk.
3, risk analysis: the emergence of poisoning
Safety measures:
Combustible gas detector, toxic medium detector.
Operators must wear protective equipment.
Personnel import and export and evacuation protection measures have been implemented: A ladder B, repair slope.
4, risk analysis: causing the fall
Safety measures:
Operating site fence, warning line, warning cards, night warning lights have been set according to the requirements.
There is sufficient lighting at night in the work site: A ordinary lamp B explosion-proof lamp.
When the operators to lay a springboard.
5, risk analysis: the combination of dangerous operations, the corresponding security measures are not implemented
Safety measures:
If it involves high, open circuit and other dangerous operations, should be handled at the same time related work permit.
6, risk analysis: the construction conditions of major changes
Safety measures:
If the construction conditions change, should apply for work permit "to" earth.
Seven, lifting operation
1, risk analysis: operation without a license
Safety measures:
Lifting and command personnel must undergo professional training certificates.
2, risk analysis: Command chaos
Safety measures:
Non emergency situations, the scene of a unified command, the signal is clear.
3, risk analysis: no warning line or warning signs
Safety measures:
There is a perfect lifting scheme, designated warning line, set up safety signs, prohibit non construction personnel into the.
4, risk analysis: poor operating conditions
Safety measures:
There should be adequate lighting at night.
In case of heavy rain, fog and strong wind at 6 or more, the operation must be stopped.
5, risk analysis: not strictly enforce the lifting operation “ ten not hanging ”
Safety measures:
Command signal is unknown or arbitrary command not hanging;
Overload or object weight is not unknown;
The heavy load is not hanging;
The lack of light, see the heavy crane;
The station is not under a weight lifting;
The weight is not hanging in the ground;
The fastening weight is not strong, rope knotted rope uneven crane;
The edge objects not put measures without lifting pad;
9 safety device failure is not suspended;
The weight over head crane.
6, risk analysis: the combination of dangerous operations, the corresponding security measures are not implemented
Safety measures:
In the process of lifting the road traffic, such as the need to block the road traffic, should apply for "open circuit".
Lifting the scene, operating personnel board 2 meters above the height of the work, should handle the "height of the work permit".
Related work permits for other hazardous operations.
Eight, blind plate pumping operation
1, risk analysis: the blind plate has a defect
Safety measures:
Blind plate material to be appropriate, the thickness should be calculated by strength, high pressure blind plate should be passed inspection, the blind plate should have a
Two handles, easy to identify, pump, should be used to match the gasket.
2, risk analysis: hazardous substances (energy) outstanding
Safety measures:
Before the dismantling of the blind plate, should bePipe pressure to pressure or micro positive pressure;
Is strictly prohibited in the same pipe at the same time two and two more than the blind plate;
Gas temperature should be less than 60;
The workers are no harmful substances (energy) may highlight the direction for personal protection.
3, risk analysis: fire and other fire

4, risk analysis: operational mistakes
Safety measures:
When the multiple blind plate is drawn, the position map of the blind plate and the blind plate number shall be in accordance with the unified command of the operation responsible person;
The signs indicate that the blind plate position should be located in each of the blind plate.
