1 Project Description
1.1Background of the Project
Yingkou City Gas Company was founded in1986, which is the only pipe-gas public
utility enterprise in Yingkou. The resource of the company is natural gas from Liaohe Oil
Field. It has been transferred to the gas source plant located at Laobian District, Yingkou
City, via a 45-km pipeline from Liaohe Oil Field. After the pressure adjustment, it has
been sent to the whole city. The pipes and gas tanks have been aged after many years’
usage and the gas system is unable to meet the request of the expanding city of Yingkou.
Since then, the city’s gas system needs to be updated; the energy consumption of the
city needs to be optimized in order to assure the city’s demand. The pipelines of the gas
system of Yingkou have been using for many years; the geological condition of the city is
not good enough; the accessory is not enough; the rate of gas loss keeps at high level; and
there are some serious hidden trouble in the system. So Yingkou City Gas Company takes
out this project.
The route of the pipeline and location of Yingkoou Coal Gas Company are described
as figure 1-1.
1.2Name, Location, Nature, and project plan
Name: Reconstruction and Expansion Project for Gas Facilities of Yingkou City
Location: Yingkou City

Loan and the other from self-funded
Construction Plan: September 2008 – November, 2009
1.3Construction Contents of Project
Three contents in this construction project
1. Overhaul of the wet-style storage cabinet of the gas source plant (one is 20,000
m3, the other is 50,000m3) and build a new dry-style storage cabinet (50,000 m3)
2
2. Set up an intelligent gas management system
3. Gas pipeline rehabilitation: rehab of 9km natural gas transmission pipeline
(DN200), upgrading of middle pressure pipeline of 20km (DN200-DN300) and of low
pressure pipeline of 15km (DN200). Rehabilitation of 20 (middle pressure) and installing
of 40 (low pressure) new valves, and build cathodic protection system of about 280 poles.
The details is as followed,
1.3.1 Overhaul and building of storage cabinets in the gas source plant
Overhaul for the wet-style storage cabinet of the gas source plan (one is 20,000 m3,
the other is 50,000m3), including:
Change the rotten steel board;
Amend some of the wall board;
Adjust tower guide pulley;
Stabilize the entrance and exit of the pipes.
Besides, build a new dry style storage cabinet of 50,000 m3 at the free space in the
gas source plan.
1.3.2 The construction of Gas Intelligent Management System
Set up a Control Center with gas intelligent Management System. Transfer the
signals and commands between different units and controlling points via Supervisory
Control And Data Acquisition (SCADA) System; Transfer the signal and commands in
the pressure-adjustment stations and valve of the urban area’s gas system; Transfer the
parameters of the user gap consumption; Load or save the documents such as the
company’s files or original data.
1.3.3 Pipeline system reconstruction
1. Make a 20km-long steel pipe of medium-pressure (0.4MPa) as the main pipe from
Zhuanglin Road to Qinghua Street, which will be made of PE pipe. This pipe will connect
the natural gas distance transferring pipe in Hanhe Bridge. Pressure does not need to be
readjusted in natural gas plants.
3
2. Three pressure adjustment stations will be setup on the new 0.4MPa main pipe,
which locates at Lianmeng Road Cross, Guanghua Road Cross, and Qinghua Road Cross.
The stations will transfer gas to the urban medium-pressure pipe (0.15MP), which will
expand the gas supply area and gas supply ability.
3. Change the pipeline with 9km length, from Liaohe Oil Field Gas Station to the
south bank of Daliaohe River, Tianzhuangtai Town. The part from Liaohe oil field gas
station to Xintun Pressure Adjustment Station Dawa County will be changed to Spiral
submerged arc - welded steel pipe which has been strengthened by 3 layers PE pipe and
the part from Xintun Pressure Adjustment Station Dawa County to the south bank of
Daliaohe River Tianzhuangtai Town will choose PE pipe.
4. Replace the medium or low pressure cast iron pipe and its accessory (such as
valves) with hidden safety trouble. The total length of the pipe is about 15 km.
5. Replace about 30 rotten valves, meanwhile, we will choose valves with distance
controlling in order to cater for the gas intelligent management system.
6. Add up sacrificial anodes cathode protection equipment in the areas of serious
corrosion problem. The total number is about 280 (70 sets).
7. Add up about 40 valves in some key point of the low-pressure pipes and the pipe
entrances or exits in the living areas where accident often happens.

2.2Design Basis
This Environmental Management Plan is designed according to the laws and regulations
of environmental protection in People’s Republic of China; World Bank Safeguard
Operation Policy; related environment protection rules and structured documents in
Yingkou city; the design documents of this project; technical documents on the
construction project’s environmental impact assessment of PRC Environmental
Protection Agency; international environment protocols that signed by China; etc.
3 Pollutant Discharge
3.1 Waste Gas Emission of the Project
No atmospheric pollutant will be produced while the project runs normally. If the
pipe pressure were over the normal, the adjustment stations will activate the safety valve.
Since this program aims to the amendment of medium-low pressure pipe, and automatic
protection unit will be setup, over-pressure problems will seldom appear, so the nature
gas leak will be little.
3
3.2 Waste water
The waste water during the project’s running is mainly the daily domestic waste
water. Since no new workers needed in this project, the water consumption keeps the
same as before.
3.3 Noise source
The noise source of this project is the new gas pressurization machine’s noise (85-
90dB(A)). Besides, if the new pressure adjustment station’s pressure is over the normal
range, the safety valve will be activated, just at the moment the gas released, noise will be
burst out at the maximum of 85 dB(A).
3.4 Solid waste
The solid waste of this project is the 3 new adjustment station’s used filter, which
will be replaced on time. Usually, filter will be changed ever 3 months. The weight of a
filter is about 0.5kg, so the yearly solid waste is about 0.006t/a.
3.5Pullutant reduction by the newer for the replacement of the old
one
The main method of using the new to replace the old in this project is to solve the
over release of smoke and dust from the factory’s boiler and daily waste water. By means
of the update of the boiler’s dust remover and water treatment system, the correct smoke
filter system and waste water treatment system will help the factory reduce pollutant and
reach the limit , so that the amount of pollutant will be reduced. After this method, the
pollutant of Yingkou Coal Gas Company will be as follow table 3-1.

According to the above date, all the areas of Yingkou City’s noise reaches the
standard, the Sound Environment Quality is good.
4.2 Environmental Impact Analysis in Construction Period
4.2.1 Analysis of Ambient Air Impact
The air pollution during this project comes from the following activities: dust
during the pipe channel digging by the bulldozer; dust spread by the basic contraction
of the storage cabinet, vehicles, road digging, and mechanical running; the dust and
splash of the mechanical materials (such as cement, lime, and sands) during the
transportation, and the waste gas from the mechanics, vehicles and generators.
1. Flying Dust Impact Analysis during Construction
Reference by general contraction fields’ data, the daily TSP can be within the
standard in the places, where is 50 m away of the field pipeline
The new storage cabinet will be built in the yard of the gas source plant, and the
nearest residential place in Laobian District is 400m away from the factory. With the
above method, the dust during the cabinet construction will affect the residents little.
2. Exhaust Waste Gas Impact from the Vehicle Analysis during Construction
The amount of waste gas from the vehicle is minor; most of the pipes will be
built near the main traffic line in the urban area, and the gas source plant locates by
the Yingkou-Dalin Road. These roads are quite busy; the additional volume of traffic
flow is not too much. So, the additional air pollution by the vehicles can be ignored.
7
4.2.2 Analysis of the Water Environmental Impact
The waste water during the construction includes the waste water from the
pipeline construction and gas source plant construction.
1. Waste water from the pipeline construction
-waste water for the pipe installation
Most of the pipelines will be installed in the urban area. The possibility to touch
the underground water level is quite low. So the waste water is mainly the cooling
water for the mechanics, and washing water for the transportation, and the waste
water with oil dropped by the mechanics, the total volume of waste water is minor. If
it rains, the water resistant instrument in the construction field can reduce the flow to
take the dust, sands, rubbish, and waste soil away. The waste water fits the standard of
the treatment factory, so it will be sent to the drainage treatment plant for treatment.
So, the minor amount of waste water can be controlled in the limits of the standard by
means of the above methods.
- Waste water while across the pipeline
The main pipe will come across the rivers for 7 times, except the pipe with
bridge installation will be used in the Bohai Street across Qinbai River, the directional
digging methods will be used in the rest places.
During the directional digging methods, a little waste mud and solid waste will
be produced. The main component of the mud is bentonite and a little addition agent,
which are non-poisonous and harmless. But if the mud comes into surface water
directly during the rainy season, it may raise the percent of sands in the nearby rivers,
canals or drainage pipelines; increase the amount of suspended particle in the river
and the turbidity degree. This report requests mud-collecting and disposal pool set up
by the borer, only the supernatant fluid is allowed to be discharge. With the above
methods, the affection to the water quality during the construction can be limited in
the acceptable range and no obvious affection appears in the water environment.
Pipe with bridge installation will be used in the Bohai Street across Qinbai River,
since no ships needed, there will be no affection to the water environment.
2. Waste water in gas source plant during construction
The construction of this plant is a general construction, which waste water is the
8
cooling water for the mechanics, and washing water for the transportation, the
waste water with oil dropped by the mechanics, and domestic waste water
produced by the constructors. This construction area is quite small, waste water
produced by mechanics is not much; most of the waste water is domestic waste
water. The report requests Yingkou Coal Gas Company to install a whole set of
domestic waste water treatment before the cabinet construction, which can
make the domestic waste water fit Grade II of LiaoNing local standard on
discharge of wastewater and exhaust gases (DB12-60-89).
With those methods, the waste water during the construction of the plant can be
controlled in the acceptable range.
4.2.3 Analysis of the Acoustic Environmental Impact
Most of the pipelines located at the main streets or road of Yingkou City, which
will affect the daily life of the citizens. So, nighttime construction is forbidden,
besides, even in the daytime, strict methods will be carry out to reduce the noise
affection to the environment. The project should adopt the method of segmental
construction to reduce the impact the surrounding residential area. the impact is
temporary and acceptable.
The noise in different stage of the construction will be controlled between 85-
100dB (A), the noise source is intermittent during the construction. Since there are not
residential areas or other environmental hot places within 1000 m of the field, and
only daytime construction allowed, there will be no affection to the residential.
4.2.4 Analysis of the Ecological Environmental Impact
This cabinet construction will be built in the existing plant, no new land
occupied.
1. Temporary Land Occupation
Pipelines reconstruction will be done to the original pipe places, no trees will be
felled; new pipes will be done in the pavement’s reserved gas pipe areas of the new
roads; suburbs pipe reconstruction areas are mainly dry lands. Since the construction
will be made from January to April, affection to the plants is little. In the urban area,
9
people and the mechanics dig together, the stage excavation method is adopted in the
cultivatable land and protect the former ecological environment for the landfill with
the bottom soil which is separated from the surface soil when digging. In addition, the
accumulated landslide should be reserve to prevent the ground surface sink and soil
and water loss for the runoff and rainfall. The soil used for the landfill is the deserted
soil and disposal properly in the field. The environmental impact on the ecological
will be reduced with the above methods.
2 River-crossing impact
The river-crossing methods of the project are pipe with bridge installation and
directional digging methods. Since directional digging method will not touch the
water, and pipe with bridge will not use a ship, there will be no affection to the river.
And the affection to the water environment is temporary, so this minor affection will
become less and less, and disappear finally.
4.2.5 Analysis of Solid Environmental Impact
Solid waste during construction includes: waste pipes and valves, domestic waste
produced by the constructors, waste soil during pipe construction, dry-mud during the
digging, and the building waste during the construction of gas source reconstruction.
1. The weight of waste pipes and valves is about 1400t, can be recycled and sold
out, which will not affect the environment.
2. The total amount of domestic waste of the pipe and factory construction is
about 130kg/d, which will be collected by Yingkou Environmental Sanitation
Department, there will be little environmental affection.
3. Most of the pipe working is old pipe update and the digging soil equals to
refilling, the new medium-pressure gas pipe locates at the new road of Zhuanglin
Road and Qinghua Street, the solid waste can be used as the roadbed, the construction
waste can be used to pave the road.
With the above treatments, the solid waste cannot affect the environment
seriously.
4.2.6 Analysis of the Society and Traffic Impact
The range of this project’s pipeline is quite broadly, especially in the main road
10
of the urban area of Yingkou. Since these streets are busy, and many passengers
nearby, the construction field will occupy the non-vehicle roads and pavement, which
will affect the traffic seriously. The noise of it will affect the residential. After the
construction plan has been made, it should be declared to the public in advance, to
minimize the affection of the citizen’s daily life and traffic.
But the pipe construction is step by step, and the affection is temporary and part,
as soon as the construction finishes, the impact will be disappear. By the conversation
with the residence, and get the understanding, the impact to the society and traffic can
be acceptable.
4.3 Analysis of the Environmental Impact in Operation
4.3.1 Analysis of the Ambient Air Impact
This project can not only change the rotten and old gas pipes of Yingkou city,
which will reduce the gas loss, but also will raise the natural gas consumption of the
city, so that change the energy consumption structure, reduce the consumption of coal,
so that the SO2 and dust can be reduced, which will clear the atmosphere of Yingkou
City.
Besides, according the requests of the evaluation, as the building of 50,000 m3
dry-style gas storage cabinet, the 2 old 4 ton steam boils’ dust remover will be
updated. As the engineering analysis, after the update of the dust remover, the smoke
can be limited as lower than 97 mg/m3 which fit the standard. The reduction of smoke
discharge is 12.3t/a, or 80%. It can improve the air condition around the gas source
plant.
4.3.2 Analysis of the waste water impact
As the construction analysis, this project will not increase the waste water
discharge of Yingkou Coal Gas Company, and as the request of this evaluation, the
plant should install a whole set of domestic waste water treatment, which can make
the domestic waste water fit Grade II of LiaoNing local standard on discharge of
11
wastewater and exhaust gases (DB12-60-89). all the pollutants in the waste water will
be lowered. It can improve the water quality of Laobianhe River.
4.3.3 Analysis of Noise Environment Impact
The Noise of the project is the running noise of the new gas compression
machine (85-90dB(A)). The new machine located inside the original machine room,
which can reduce the noise at about 25dB(A), the noise value after the distance decay
to the plant boundary and superimposed the existing boundary noise is as table 4-4.

As table 4-4, the boundary noise of the gas source plant will keep the existed
level and do little impact on the boundary noise and meet the requirement of Standard
for Noise at Boundary of Industrial Enterprises Grade Ⅱ(GB12348-90).
And, the instant noise while the new pressure adjustment station pipe’s pressure
is too high, noise reduction instruments and methods are applied. The new stations
located at the main crossroad with the equipment of the overpressure exhaust pipe
fitting the mufflers meet the requirement of Standard of Environmental Noise of Urban city
Gradeⅳ(GB3096-93)4.3.4 Analysis of Solid Waste Environment Impact
The solid waste of this project is the old filter of the 3 new adjustment stations.
12
The amount is about 0.006t/a. the waste filters are general solid waste, and the amount
is minor, which will be sent to Yingkou Solid Waste Treatment Plant, which will not
affect environment.

2) Gas pipeline
The natural gas has been transferred from Dapingfang Gas Staion, Liaohe Oil Field to
the gas source plant and the urban area via underground pipes. The length of the high-
pressure pipe (0.6MPa) is 6 km, middle-pressure pipe is about 51.8km (0.4Mpa:
37.1km, 0.15Mpa: 14.7km). Considering the different danger of the pressures, the
range of the evaluation includes the above middle and high pipeline only.

5.3 Risk probability and the confirmation of the sources
(1) Storage Unit
The probability of the fire/explosion of the natural gas tank in this project is
4.0×10-7/a, referenced by domestic statistics.
The ordinary banks leak usually occurs at the jointing of the tank and the pipe, or
the valve. Here, we presume that the jointing part of the gas-in pipe/gas-out pipe
break in one of 50,000 m3 tank, and the natural gas leaks, the operators have stopped
the gas leaking within 30 minutes. After calculation, if the gas-in pipe is broken, the
leaking rate of the gas is 0.046kg/s, the amount of leaking gas is 82.8kg; if the gas-out
pipe is broken, the leaking rate is 0.062kg/s, the amount of leaking gas is 111.6kg.
(2) Transportation units
15
After the construction, the length of the high-pressure pipe (0.6MPa) is 6 km,
middle-pressure pipe (0.4Mpa) is 37.1km. We presume that two kinds of pipes are
broken, the leaking part is 60% of the diameter with 20mm perforation. The
calculation result for 30 minutes’ leaking is: for 0.6Mpa pipe, the leaking rate is
2.01kg/s, the amount of leaking gas is 3618kg; for 0.4Mpa pipe, the leaking rate is
1.34kg/s, the amount of leaking gas is 2412kg.
5.4 Consequence Calculation
5.4.1 Consequence calculation for the explosion range after
leaking
1. Diffusion pattern of the natural gas
The calculation of the diffusion pattern of the natural gas should adopt the non-nomal
emission pattern Technical guidelines for environmental impact assessment (HJ/T2.1-
93)
2. The estimation of the range of the flammable explosion
Take longest distance at the lower explosion limit concentration for the natural gas in
the Leeward approaches – 33g/m3, as the longest dangerous radius. In different
meteorological condition, time, and the leeward distance from the incident place. The
result is as table 5-3.

As table 5-3, if the jointing for the tanks and gas-in pipe has been broken for 30
16
min, the density of the leaking gas cloudy cannot reach the explosion limit if it is
windy or breezy; if the High pressure(0.6MPa ) pipe or Middle pressure(0.4MPa) pipe has
been broken for 30 min, the density of the leaking gas cloudy cannot reach the explosion
limit if it is windy, the leeward explosion distance will be 6m and 5m if it is breezy.
5.4.2 Consequence calculation for the fire explosion after leaking
This part takes TNT equivalent method with over-pressure & stamping criteria
to estimate the impact range of the natural gas cloud. The result is as table 5-4.

and 83m. As the investigation, the closest residential point is 100m away from the
point, so the tank explosion will damage little outside the factory.
When 0.6MPa pipe is broken, then fire causes the explosion, the Fatal Radius, GBH
radius, slight wound radius, and property damage radius are 38m, 56m, 101m, and
116m.
When 0.4MPa pipe is broken, then fire causes the explosion, the Fatal Radius, GBH
radius, slight wound radius, and property damage radius are 33m, 49m, 88m, and
17
101m.
5.5 Risk Calculation and Assessment
5.5.1The acceptable level of the environmental risk
The environmental incident is quite unstable, so the estimation to the aftermath is
very uncertain.
According to the definition of venture:
During the procedure of the calculation, the following equation is used to
calculate the incidental risk (death/year):
Venture=Half lethal percentage area population * 50% * incident probability * weather
probability
The unit for risk is “death/year”. The level of the common incident can be
divided into max acceptable level and ignorable level. In industry and other activities,
the risk levels are as table 5-5.
Table 5-5 Risk level and the acceptable level
Risk (death/year) Risk level Acceptable level
10-3 Very dangerous, equal to the nature death rate unacceptable
10-4 Medium Must be improved
10-5 As the swimming incident or Gas poisoning
People concern it, and would like to take some preventing methods
10-6 As earthquake or other natural disasters People do not concern on it
10-7~10-8 As the meteorite hurts people No one would like to prevent this kind of incident
Chemical-engineering industry is high-risk. The evaluation takes some
recommendation acceptable level according to different country’s situation, as table 5-
6.

As table 5-7, the max venture for the project is 3.7×10-6, which is lower than the
acceptable risk 8.33×10-5.
5.6 Risk Control Measure and Emergency Response Plan
5.6.1 Risk Control Measure
This project is going to set up an SCADA management system for the safety
running of the gas pipe and reduce the potential risks. This system will be controlled
by the administration center at the Yingkou Coal Gas Company’s building. Here, the
standard, layout, equipment models, fire control, automatic management, and running
19
management will be analyzed for the risk control.
(1) Design Standard
The standard of the gas pipe and gas source plant are Code for design of urban and
rural gas supply (GB50028-93, version 2002) and Code for fire protection design of the
buildings(GBJ16-87, version 2001). They are the criteria general acceptable in China,
the existing cases have confirmed the security. So the standard of the pipes and
factory is guaranteed.
(2) Layout for the tank and pipes
Dry-type storage tank
A new 50,000 m3 Dry-type storage tank will be set up to the east of the existing
50,000 m3 wet-type storage tank, the safely distance to the around buildings accord
with Code for design of urban and rural gas supply and Code for fire protection design of the
buildings The width and Radius of turn for the road in the raw gas factory cater to the
requests of fire prevention and transportation.
The new 50,000m3 Dry-type storage tank is more than 150m away from the hot
points outside the factory, such as the resident points. According to the estimation, the
tank explosion affects little outside the factory.
Gas Pipeline
The pipeline from Dapingfang Station to Laobian gas source plant is the existing
pipe. This time, only the pipes from Dapingfang Station to Xintun Pressure-
adjustment station and the part which will come across the Daliaohe River will be
replaced. The routine of the pipe is unchanged. The new middle pressure pipe will be
laid along Zhuanglin Road and Qinghua Street; the middle pressure and low pressure
pipe in the urban areas will be replaced without routine change. Because of the need
of gas supply, the working in residential area is unavoidable and the risk will be
prevented during construction and management.
(3) Equipment models
Type of the tanks
20
A new 50,000m3 Dry-type storage tank, and the accessories, such as pressure
adjustment instrument, flow meter, pipes, compressor, and valves. As the reports, all the new
equipments will be in according with Law of the Peoples Republic of China on Bid Invitation
and Bidding: for the high equality and stability.
Height measurement to the 50,000m3 Dry-type storage tank without height alarm
if the height is above the alarm line sound and light alarm will start.
Combustible gas detector will be set up in the factory’s tank valve room, because
the raw gas factory is the explosion prevent Area, Class A.
Emergency amputation valve and safety out-spreading valve will be set up at the
entrance and exit to the tank, when the tank pressure reaches the level, the valve will
be closed automatically, when the pressure is over the safety valve’s point, the safety
valve will be released automatically, so that the tank can run safety.
Types of the pipeline
According to the report, the update part from Dapingfang to Xintun Pressure
Adjustment Station will take Spiral Submerged Arc Welded Steel, the other new or
update part will use PE pipes. For the steel part, 3 layerss PE corruption-preventing
method will be taken, and 100% Inspection will be made. Valves will be set up every
2km.At all the crossing important rivers parts, and middle pressure start points, valves
will be set up in valve wells or directly. The materials for the pipes and valves will be
in accordance with the standard. All the pipes are underground, so that the damage
from traffic incidents can be avoided.
The possible reasons of the other domestic gas pipe incident are pipe’s quality, or
the not-enough protection to the nearby gas pipe during the other underground
construction. So, after the installation, marked alarm signs with the gas company’s
and police telephone must be set along the pipeline.
Besides, leakage inspection and emergent repairing instruments must be set up,
so that the leaking points can be found quickly and exactly, and emergency repairing
will be possible.
(4) fire control,
21
As Code for fire protection design of the buildings, after the new 50,000 m3 Dry-type
storage tank’s construction, the storage ability for the factory will be 1,200,000 m3,
the fire control water is 30L/s(108m3/h). As 3 hours calculation, the total fire control
water is 324m3.
There is a 600 m3 fire hydrant reservoir to the south of the new tank, which fits
the request of the fire controlling. Fire controlling pipes will be set up as a circle, the
diameter is DN150. 3 and fire hydrants will be set up outside the reservior.
The damage of fire in the raw gas factory is quite dangerous, and the fire caused
by gas is difficult to be controlled, so the most effective way for this kind of fire is to
cut the gas. To ensure the safe running of the factory, combustible gas inspectors, fire
controlling system, and mobile fire extinguishers are quite important for the fire
happen. The other fire extinguishment can rely on the local fire station.
(5) Automatic management
Automatic management is quite an important part for the city gas supply. To
ensure the stable running of the natural gas network and reduce the potential risks, a
SCADA management system will be set up for this project. This system is a 3-level
distributed control system, a controlling center will be set up in the Gas company’s
office building, which is a system administrator in charge of data monitoring; the
SCS, High-middle-low pressure adjustment stations and middle-low pressure
adjustment stations are the 2nd level; RTU System in the network, data collection and
system control are the 3rd level. The 3 layers system combined with cable or wireless
network to work as a SCADA System. 3 SCS will be set up independently along the
high pressure pipes: High-middle pressure adjustment station at Lianmeng Road,
Huanghua Road, and Qinghua Road. 30 valves updated in the middle pressure
network will be set up as distance RTU terminations. These automatic management
systems are not only to ensure the gas supply, but to keep the pipes and factory safe.
(6) Operation management
The operation management includes:
22
Safe and fire protection committee: Voluntary fire brigade, gear groups, Rescue crew, and
Public security Crew. Anti-fire drills will be practiced on time, anti fire plans will be constituted
with the guidance of local fire stations.
Rules, such as safety operation regulation, Fire protection responsibility system, post
responsibility system, daily and preventive maintenance system, and the regular System of
examining and assessment for the staff
Staff safety and technique education, all the worker at the production line will pass the exams
first
Technical document management, regular and daily check/fix
Direct line telephones set in important section for the emergency help
Fire alarm, notice the staff and nearby units as soon as the incident happens
Post set at the entrance to the working area. Post with “Smoking and lighting fires strictly
prohibited.” set on the wall to the working areas and in the living area/
Strictly obey the national and gas industry’s rules and regulation for safety
Regular inspect, management, and maintenance to the fire-fighting equipments
Put out the initial fire in time: operate the firefighting pump, water system, and
use powder fire extinguishers to put out the fire promptly
Cut off the electricity as soon as the leaking gas fire in the station’s workshops.
Close all the related equipment, pipes (close the emergency valves at the entrance and
exit), and take effect methods, report it to the local fire station and controlling center.
The above methods are the existing management methods, system, and
organizations in Yingkou Coal Gas Company.
5.6.2 Emergency Response plan
Natural gas is a kind of inflammable and explosive substances. Although strict
risk preventing methods are taken for the storage and transferring, leaking incidents
are still possible. The leaking gas explosion will be possible with the open fire, which
23
will endanger the nearby people and buildings. So as Technical Guidelines for
Environmental Risk Assessment, Accident emergency predetermined plan must be
made for this program.
The Emergency response plan of accidental risk in this project is as table 5-8.
