3.62. Additional safety measures when working in underground structures and tanks.

- All underground structures should be checked for the content of the most likely harmful substances in the air of the working area immediately before admission to them.

- For underground structures located in the immediate vicinity of the underground gas pipeline (at a distance of up to 15 m on both sides of it), the timing of inspections, the procedure for servicing and lowering people into them must be determined by the instruction approved by the chief engineer of the enterprise.

- If gas is detected in any of the structures accompanying the gas pipeline, it is necessary to take measures to ventilate them. At the same time, other underground structures within a radius of 50 m from the gas pipeline must be additionally checked for gas contamination.

- Characteristics of the most common explosive and harmful gases in underground structures are given in Appendix 5.

- All gas hazardous underground structures must be marked on technological schemes and route maps. Gas-hazardous underground structures must have a special hatch coloring (it is recommended to paint the second cover of the hatch or its cylindrical part yellow).

- The presence of the most likely harmful substances in the air of an underground structure or reservoir must be determined by a gas analyzer. Air samples should be taken using a hose lowered into the hatch of an underground structure or tank.

— Air samples should be taken from the most poorly ventilated areas of the upper and lower zones of an underground structure or reservoir. When sampling from the upper zone, the end of the hose must be lowered inward by 20 - 30 cm. In this case, a harmful substance with a lower density than air can be detected. To detect harmful substances heavier than air, sampling should be carried out from the lower zone of the underground structure, while the end of the hose should be lowered at a distance of no more than 1 m from the floor (ground).

- It is forbidden to descend into underground structures and tanks for air sampling.

- Before and during work in an underground structure or tank, natural or forced ventilation must be provided.

- Natural ventilation of chambers and channels should be created by opening at least two hatches with the installation of special visors near them, directing air flows into the hatches. Before people descend into an underground structure or climb into a tank, the duration of natural ventilation should be at least 20 minutes.

- Forced ventilation should be carried out if there is an underground structure or reservoir of harmful substances in the air or the air temperature in it is above 32 ° C.

- Forced ventilation can be provided by a mobile fan or compressor with a complete air exchange in an underground structure or tank for 10 - 15 minutes. The fan hose lowered into the underground structure should not reach the floor level by 20-25 cm.

- If natural and forced ventilation do not provide complete removal harmful substances, descent into an underground structure or reservoir is allowed only with the use of means that isolate the respiratory organs (self-rescuers PDU-3, SPI-20, etc., a hose gas mask). The use of a hose gas mask is permitted provided that there are no harmful and dangerous gases at the place of air intake.

— It is forbidden to ventilate an underground structure or reservoir with oxygen.

- At a distance of 10 - 15 m from the open hatches of underground structures located on the roadway, warning signs should be installed on both sides of the traffic. Outside settlements, at a distance of at least 50 m from the place of work, a warning road sign is additionally placed on the side of traffic. The work site must be fenced off. At night and in conditions of insufficient visibility, warning road signs, as well as a fence near the work site, must be illuminated with lamps with a voltage higher than 42 V. The fenced area at work sites and passage to hatches in winter time must be cleared of snow, ice and sprinkled with sand.

- Before allowing personnel to work in tanks and underground structures, pipelines through which gas, acids and other aggressive substances can enter must be turned off, plugs must be installed on their flange connections, warning posters or safety signs “Do not open - people are working."

- When opening the hatch of an underground structure or tank, you should stand on the windward side (with your back to the wind).

- The time spent in an underground structure or reservoir, as well as the duration of rest with an exit from them, is determined by the work manager, depending on the conditions and nature of the work, indicating this in the line of the "Special Conditions" order.

– It is allowed to work in an underground structure or tank (except for tanks for storing fuel and oils) at an air temperature in it above 32 ° C only in exceptional cases (in case of an accident, if it threatens people's lives, destruction of equipment, etc.) with the permission of the head works and under his direct supervision with the adoption of the necessary measures to prevent burns of personnel.

- When the air temperature in the underground structure or tank is above 32°C, work should be done in warm overalls. If there is a liquid medium in an underground structure or reservoir, rubber shoes must be used.

- It is forbidden to work in an underground structure or reservoir when the water level in it above the floor level is higher than 200 mm, as well as at a water temperature higher than 45 °C.

— Descent of workers into underground structures filled with steam and basements regardless of the air temperature in them is not allowed.

- To work inside an underground structure or tank, as well as for periodic inspections, an instructed team consisting of at least three people should be appointed, of which two should be at the hatch and monitor the condition of the working and air intake pipe of the hose gas mask. It is forbidden to allow unauthorized persons to the place of work.

— Observers do not have the right to leave the hatch of an underground structure or reservoir and be distracted by other work while a person is in an underground structure or reservoir.

- When working in an underground structure of great depth and length, when it is impossible to maintain visual observation of the worker, communication must be organized with him using the received signals or telephone.

- If a worker in an underground structure feels unwell, he must stop working and go to the surface, while the observer must help him, involving nearby personnel.

- If necessary, go down to the victim, one of the observers must put on an insulating device (self-rescuers PDU-3, SPI-20, etc., a hose gas mask) and a rescue belt, passing the end of the rescue rope to another observer who remains at the top.

- Before starting work, it is necessary to check the serviceability of the gas mask and hoses.

- For a gas mask with forced air supply, the serviceability of the blower and the operation of its drives must also be checked. The tightness of the gas mask and the hose is checked by clamping the end of the hose with a hand while wearing a gas mask. If it is impossible to breathe in this position, then the gas mask is working.

- Before descending into an underground structure or tank, the corrugated hose that supplies air to the breathing valve of the gas mask must be fastened to the waist belt.

- The air intake pipes of the gas mask should be located on the windward side of the place of release or the place of possible release of harmful substances and strengthened in such a way that dust is not sucked in from the soil surface. In the absence of forced air supply using a fan, the length of the hose should not exceed 15 m. The hose should not have sharp kinks or be pinched in anything.

— Analysis of air in an underground structure or reservoir should be carried out using explosion-proof gas analyzers, and in their absence, by taking an air sample and analyzing it outside the structure or reservoir.

- When working inside a gas hazardous underground structure or tank, the use of rescue belts and ropes is mandatory.

- Rescue belts must have shoulder straps on the back with a ring at their intersection for attaching a rescue rope. The belt should be adjusted so that the ring is located no lower than the shoulder blades. The use of belts without shoulder straps is prohibited. The other end of the rescue rope must be in the hands of an observer.

- The following signaling is used to communicate the observer and the worker in a gas-dangerous underground structure or reservoir:

· one jerk of the rescue rope for those working in the structure (tank) means “Tighten the hose and rope”. At the same time, they must be pulled up after the observer gives a signal (one jerk) and receives a response signal from a gas-dangerous underground structure or reservoir in the form of a single jerk. If there is no answer, you need to start extracting not only the hose and rope, but also the working one, since it is possible that the jerk was due to its fall;

· two jerks mean "Lower the hose and rope." Such a signal will be given by a worker, located in a gas-dangerous underground structure or reservoir, when he needs to move;

Three pulls means "All right". The rope and hose are pulled by a worker located in a gas-dangerous underground structure or tank, so the observer must hold the rope and hose so as not to interfere with their movement and prevent them from falling. As soon as the worker has stopped moving, he must give a signal - three jerks, which means "Everything is in order." The observer, having no signal after stopping the movement of the rope and hose, must request the worker with one jerk, to which he must receive a response with three jerks.

· repeated jerks of the rescue rope, filed by the observer, mean that the worker, who is in a gas-dangerous underground structure or tank, must approach the hatch or climb up. The same signals given by the worker, who is inside the tank, mean the requirement to remove it.

- Observers should be located on the windward side, periodically check the health of the worker and, at his signal, lower or pull out the rescue rope and hose.

- If, despite ventilation, the presence of harmful substances is detected by the device, then work in the underground structure should be prohibited until the entry of harmful substances is eliminated and a second check confirms their absence.

- If it is impossible to eliminate the flow of harmful substances into an underground structure with enhanced ventilation, it is necessary to descend into it and work in it in a self-rescuer (SPI-20, PDU-3, etc.) or a hose gas mask.

- Before closing the hatches after the end of work, the manager and foreman must make sure that no one of the workers accidentally remained inside the underground structure or tank, and that materials, tools and other foreign objects are not forgotten there. It is forbidden to leave hatches open after completion of work in an underground structure or in a tank.
