The nameplate of the power supply device should be complete and clear. 10.4 Monitoring, interlocking and alarm system instruments 10.4.1 The alarm system instruments and switches used for monitoring and interlocking should not be removed or short-circuited at will. 10.4.2 The test, reset, silencer, memory and tone distinction functions of the alarm instrument should be intact. 10.4.3 The instrument actuators such as solenoid valves, safety valves, regulating valves and speed regulating devices belonging to the instrument system should be regularly calibrated and positioned. 11 Fire-fighting facilities
11.1 The configuration of mobile fire-fighting equipment
SY 57371995
11.1,1 Oil pumping stations and other flammable and explosive places should be equipped with portable or cart-type fire extinguishers. 11.1.2 The configuration standard of fire-fighting equipment shall be in accordance with GB140. Low-multiple foam fire extinguishing system is in accordance with GB50151.11.2 Fixed fire pump room
11.2.1 The on-duty personnel of the fire pump room should be familiar with the performance of all equipment in this position, the fire extinguishing process, the fire extinguishing combat plan, and conduct drills regularly.
11.2.2 The fire pump room should be manned 24 hours a day and should not leave their posts without permission. 11.2.3 The communication of the fire pump room should be unobstructed and the fire pump should be able to start at any time. 11.2.4 The fire pump should be turned once per shift, and the pump should be opened and drained once a week. Each operation should not be less than 301in, and records should be kept. 11.2.5 Check the valves and fire hydrant boxes of the fire pipelines every shift, and deal with any problems in time. 11.2.6 Test spraying of the oil tank fire water system in May and June every year, and test foam once every 2 to 3 years. 11.3 Management of fire water tanks (pools) and storage of foam liquid 11.3.1 Requirements for fire water tanks (pools):
a) Fire water tanks (pools) are special facilities for fire fighting and no unit or individual should use them without authorization: b) Fire water tanks (pools) should always maintain the highest water level and the water tanks (pools) should be kept clean: c) The location of the fire water tank (culvert) should be marked and kept in good condition. 11.3.2 Storage of foam liquid:
a) Foam liquid should not be placed in the open air. The temperature of the storage environment is: 0-40℃ for plant protein foam liquid, -5-40℃ for animal protein foam liquid and fluoroprotein foam liquid;
The storage volume of foam liquid should be able to meet the sum of the amount of foam liquid required for one fire extinguishing and the amount of foam liquid contained in the foam mixture filling the pipeline;
c) The foam liquid stored in the foam liquid tank should be replenished in time after use;) The foam liquid should be checked monthly for foaming condition, and a comprehensive chemical inspection should be carried out on the foam liquid every year. If it does not meet the requirements, it should be replaced in time.
11.4 Fire extinguishing and cooling after oil tank fire
11.4.1 If an oil tank catches fire, fire extinguishing should be carried out under unified command, and the fire scene should be guarded and protected. 11.4.2 After the fire pump room attendant receives the fire alarm: the process should be quickly reversed, and the cooling water pump and foam pump should be started within 3 minutes. 11.4.3 After the fire pump is started, the cooling water should be immediately delivered to the burning oil tank and the adjacent oil tanks that need to be cooled. The foam mixture should be delivered to the burning tank within Snmin after the pump is started.
11.4.4 After receiving the alarm, the station's own fire truck should arrive at the fire scene within 5 minutes. 11.4.5 According to the tank position, estimate the possible spraying and boiling time, and take safety measures to prevent casualties. 11.4.6 After the oil tank fire is extinguished, the following measures should be taken: a) Continue to cool the tank wall uninterruptedly until the tank temperature is reduced to the temperature before the fire; continue to supply a certain amount of foam liquid to increase the thickness of the foam coverage to prevent the crude oil from re-igniting c) Strengthen on-site monitoring to prevent the burning again. 11.4.7 Cooling of the burning oil tank and adjacent tanks: a) The water for cooling the oil tank should be sprayed on the upper part of the tank wall; b) The cooling water should be continuous and evenly cool the tank wall to prevent the tank wall from being deformed and damaged by cooling; c) Cooling water should not be injected into the oil
