Compilation of equipment safety operation procedures

Safety operation procedures for maintenance, opening and closing of inverted siphon gate

First, the preparation work before operation:

1. Make the operation plan,

Before operation, the underground operation ticket must be submitted to the security department. It is forbidden to carry out underground operation without the approval of the operation ticket, and the person in charge, guardian and operator of the operation must be clearly defined.

1, operation ticket

2. Ventilation equipment

3、

2. Before the operation, all manhole covers of the inverted rainbow connection well chamber must be opened, and safety signs should be set to discharge toxic and harmful gases through natural ventilation or mechanical ventilation.

3. Use a gas detector to detect the inspection wells that need to be operated, and the detection depth is up to the operation surface (the detection content includes: the unit cubic content of oxygen, hydrogen sulfide, methane, carbon monoxide and combustible gas). The test results of the gas detector can only be operated within the allowable range.

4. Check the safety protection measures. Operators should prepare safety signs in advance, and check whether the mechanical equipment and tools used in the construction are safe, reliable, intact and applicable, and whether the equipped safety protection equipment is complete. The wearing of safety products should include: safety helmet, self-priming respirator, work shoes, work clothes, reflective vest, gloves, etc. Underground workers must wear safety ropes and carry toxic gas detectors with them.

Second, the gate opening and closing and maintenance operation:

1, 1 Underground workers must wear personal protective equipment before they can go down. In the process of underground operation, at least two people are on the well to monitor and hold the safety rope on the workers.

2. When the operators run into the platform in the inverted rainbow gate well, they need to ensure whether the ladder is firm and reliable, check the current situation in the well, ensure the safety of the platform, and ensure that there are no sundries piled up. And then you can go down the well.

3. Install the appropriate gate handle on the gate hoist. Shake the handle clockwise to close the gate and counterclockwise to open the gate.

8, long-term underground operations, should take turns to go down the well, the following well operators have dizziness, leg weakness, breath holding, nausea and other discomfort, must immediately go down to rest.

9. All electrical appliances used in underground operations must have explosion-proof functions, including lights and power switches.

10. When working underground, the person in charge of construction and the supervisor must stick to their posts, concentrate and not engage in other operations. Understand the situation of underground workers through interphone within 2 minutes, pay attention to observation, especially the state of underground workers, find problems in time, and avoid safety accidents. Smoking is prohibited in the well, and it is forbidden to throw articles and cigarette butts into the well.

1 1. In case of operation danger, rescuers need to wear oxygen cylinders to go down the well to save people, and immediately withdraw from the dangerous area, report to the construction director at the same time, and contact the emergency center in time to explain the accident location and specific situation.
