4.13. To open manhole covers of wells or remove channel overlaps, use special keys, hooks and mounts, setting them in a stable position, in order to avoid falling and injuring the hands or feet with the cover.

4.14. Remove and install fuses in the electrical devices of the TAI should be when the voltage is off.

It is allowed to change fuses under voltage, but without load (in the absence of switching devices) in goggles, using insulating pliers or dielectric gloves.

4.15. In the event of a break or violation of the density of the impulse lines coming from the gas pipeline, it is necessary to turn off the damaged area with the primary valves, leave the room, having previously taken measures to ventilate it, and inform the higher-ranking personnel on duty.

4.16. Use canvas gloves to purge the water and steam impulse lines. Purging should be done through special purge devices. If they are absent or the purge lines are clogged, the impulse lines must be purged with the permission or with the participation of the duty personnel servicing the thermal and mechanical equipment. An electrician must be at the purge site and give commands to the process shop attendant to open and close the sampling valves. The duty officer informs the electrician about production operations.

In the event of an emergency condition on the thermal mechanical equipment, it is not allowed to purge the impulse lines. If an alarm occurs during the purging of the impulse lines, then the purging must be stopped and the valve closed.

4.17. It is not allowed to tighten the connecting fittings of the sensors using levers. Open and close the connecting fittings with a wrench, the size of which must correspond to the edges of the elements being pulled, after checking the condition of the visible part of the thread.

4.18. It is not allowed to perform operations to open and close the primary valves. Maintenance of the secondary valves installed in front of the sensors is carried out with the knowledge of the duty personnel servicing this equipment.

Posters "Do not open - people are working!" must be posted on closed primary valves.

Disconnecting the sensor from the impulse line or removing the pressure gauge from it should be done by gradually unscrewing the union nut at the sensor or pressure gauge.

4.19. It is not allowed to disconnect sensors from pipelines (vessels) with open primary (selective) valves on impulse lines. If the sensor impulse lines are connected to different sampling devices, the primary valves on all these devices must be closed. Switching off the sensor powered from the common impulse line must be carried out by disconnecting devices located directly in front of the sensor.

Disconnect sensors from pipelines (vessels) with pressure over 6 MPa (60 kgf/cm2) by closing two shut-off valves installed in series, one of which is located directly at the pipeline (vessel), the other - on the impulse line in front of the sensor.

4.20. The electrician must know the places in the service area that are dangerous in relation to gas contamination. In such places it is not allowed:

• smoking;
• turning lights on and off;
• performance of work using open flames (without a work order for gas hazardous work);
• the use of an electric tool that gives sparks, and electric lighting fittings in a non-explosion-proof design;
• the use of mechanical tools (hammers, sledgehammers, etc.) made of non-ferrous metals and their alloys;
• using shoes lined with steel nails and horseshoes;
• checking for gas leaks using an open flame;
• operation of gas pipelines in the presence of gas leaks.

4.21. Maintenance of TAI devices in the premises of gas distribution points should be carried out with the permission and in the presence of the duty personnel of the boiler shop.

4.22. Before entering a gas hazardous room or underground structure, it is necessary to ventilate it and analyze the air environment for the absence of gas and the sufficiency of oxygen using a gas analyzer. Air sampling should be carried out using a hose inserted into the slot of an open door (hatch). Air samples should be taken from the most poorly ventilated places depending on the density of the gas: gases with a lower density than air (methane, carbon monoxide, hydrogen, ammonia), - from the upper zone, heavy (liquefied gases, carbon dioxide, hydrogen sulfide, oxygen) - from the lower zone.

If gas contamination is detected, it is not allowed to enter the premises (underground structure).

It is necessary to ventilate the room (structure) and again check the air for the absence of gas in it and the sufficiency of oxygen (at least 20% by volume).

If it is not possible to remove the gas, then it is allowed to enter and work in a gas hazardous place only in a gas mask.

4.23. When in a gas hazardous area or underground structure, the electrician must wear a rescue harness with shoulder straps and a rescue rope. The other end of the rescue rope must be in the hands of an observer.

4.24. When removing sensors of instrumentation, automation, protection, plugs should be installed on the impulse lines disconnected from the sensor, coming from the gas pipeline.

4.25. When servicing TAI devices on fuel supply equipment, it is not allowed to climb over conveyors, pass various objects and tools through them, and also crawl under them or pass under them in places that are not protected and not intended for passage. Passing through the conveyors should be only on the transitional bridges.

Walking on overpasses, bunker galleries, in unloading devices and rooms where conveyors are installed, one should only follow the walking paths. You must know exactly the location of the emergency stop devices for conveyor belts and be able to use them.

4.26. When servicing TAI devices on fuel oil equipment, one should not bend low to the neck of the tank hatch or look into it, as well as warm the impulse lines of combustible, explosive and harmful substances with open fire.

The use of open fire is allowed only for heating impulse water and steam lines located outside fire hazardous premises and in the open air.

4.27. Work on impulse lines and equipment, during which accidental releases of aggressive media may occur, should be carried out in rubber acid-resistant gloves, a rubberized apron and goggles or head shields.

If acid gets on the floor, it should be neutralized (sprinkled with soda or quicklime) and only then cleaned with a shovel and washed off with water.

Clothing contaminated with acid should be washed with a plentiful stream of water, neutralized with a 2-3% soda solution and changed.

4.28. When removing and installing the pressure gauge, it is not allowed to use a tool with traces of grease, as well as oily cleaning material. A non-ferrous metal tool should be used for this purpose.

4.29. When servicing TAI instrumentation located on the territory of open switchgear (OSG), the electrician is not allowed to climb the metal structures of electrical equipment. It is allowed to enter the territory of the outdoor switchgear only if accompanied by the duty personnel of the electrical department.

4.30. It is not allowed to measure the insulation resistance with a megohmmeter on non-disconnected equipment.

When working with a megohmmeter, do not touch the current-carrying parts to which it is connected with your hands.

After completion of work, it is necessary to remove the residual charge from current-carrying parts by connecting grounding.

4.31. It is not allowed to connect devices to live electrical circuits if their connection requires breaking the electrical circuit. Connection and disconnection of devices that do not require breaking electrical circuits may be performed under voltage using electrical protective equipment (dielectric gloves or tools with insulating handles).

4.32. When working under voltage on TAI devices, it is additionally necessary:

• to protect other current-carrying parts located near the workplace, which are under voltage, to which accidental contact is possible;
• work in dielectric galoshes or standing on an insulating stand or on a dielectric rug.

4.33. When working in electrical circuits under voltage, it is not allowed to use hacksaws, files, metal meters and other conductive objects.

To measure the electrical parameters of devices under voltage, you should ground the metal case of a portable device and use special probes or connecting conductors with insulating handles.

4.34. Fitting and assembly tools with insulating handles must not be held behind the stops in order to prevent the hand from slipping along the metal part.

4.35. When preparing the workplace, it is not allowed to turn off the electrical equipment of the TAI devices that affect the thermal and electrical load without obtaining the permission of the shift supervisor of the station or the shift supervisor of the corresponding workshop.

4.36. When checking the absence of voltage in electrical circuits, the use of "control" incandescent lamps is not allowed.

It is necessary to check the absence of voltage with a two-pole voltage indicator up to 1000 V, the serviceability of which is checked directly by touching the indicator to live parts that are obviously energized.

In electrical installations with a grounded neutral, when using a two-pole indicator, it is necessary to check the absence of voltage both between the phases and between the phase and the grounded equipment case or grounding (neutral) conductor.

Devices signaling the disconnected position of the apparatus, blocking devices, constantly on voltmeters are only additional means of confirming the absence of voltage, and based on their readings, it is impossible to conclude that there is no voltage.

5. Safety requirements in emergency situations

5.1. In the event of an emergency (accident, fire, natural disaster), immediately stop work and report the situation to higher operational personnel.

5.2. In cases of urgency, perform the necessary switching with subsequent notification of higher operational personnel.

5.3. In the event of a fire:

5.3.1. Notify all workers in the production area and take measures to extinguish the fire. Burning parts of electrical installations and electrical wiring under voltage should be extinguished with carbon dioxide fire extinguishers.

5.3.2. Take measures to call your immediate supervisor or other officials to the scene of the fire.

5.3.3. According to the operational situation, the local operational fire fighting plan should be acted upon.

5.4. In the event of an accident, it is necessary to immediately release the victim from the impact of the traumatic factor, provide him with first (pre-medical) medical care and inform the immediate supervisor about the accident.

When releasing the victim from the action of electric current, it is necessary to ensure that you yourself do not come into contact with the current-carrying part or under step voltage.

6. Safety requirements at the end of work

6.1. Before the end of the shift, you must:

• inspect the TAI devices and make entries in the operational log corresponding to the condition of the equipment being serviced; if there are malfunctions in the TAI devices, make an entry in the defect log;
• clean the workplace and the TAI equipment assigned to the shift; do not use combustible substances (gasoline, kerosene, acetone, etc.) when cleaning.

6.2. All tools, devices and protective equipment should be put in order and placed in cabinets and on shelves.

6.3. Inform the receiving shift about all the changes in the state of the TAI equipment that occurred during the shift, the detected malfunctions, as well as where and in what composition the teams work on the equipment of the workshop according to the orders and orders.

6.4. Report the shift handover to the higher duty personnel and issue the shift handover by signature in the operational log.

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Random news from the Archive Canon XEED 4K4Z Compact 600K Projector 09.11.2017 Canon has announced the launch of the XEED 4K600Z, a compact and bright Laser Phosphor LCOS projector with higher than hardware 4K resolution. With 4K (4096 x 2400) native resolution, LCOS technology and advanced AISYS optical system based on Canon's specialized lenses, the XEED 4K600Z projector delivers high detail and accurate color reproduction in the sRGB color space. Luminous flux - 6000 lumens. No distortion due to minimal field curvature, motion blur compensation, and ultra-fast response (1,0 frame lag at 60 Hz) further enhance image quality and viewing comfort. Sharp focus is virtually unaffected by working conditions: the image will be sharp even when projecting onto a curved or domed surface. Together with the lens, the XEED 4K600Z weighs only 26 kg. It mounts at any angle, and the +/- 60% vertical and +/-10% horizontal lens shift motor allows you to shift the image without touching the projector itself, further simplifying installation. A Wi-Fi connection allows you to remotely control the projector from iOS devices (in previous models, remote control was only possible with a wired LAN connection) . The new Canon Projector Service Tool for iOS saves time by allowing you to control your projector remotely, as well as view and resolve problems. Instead of a traditional lamp, the XEED 4K600Z is equipped with a blue laser light source, which gives a more powerful light output and allows you to more accurately adjust the brightness level. As a result, the life of the projector has increased to 40 hours, and the need for maintenance has been significantly reduced - as well as the costs due to downtime.
