What are the safety requirements of elevators for emergency trapped people s accidents?

Tell passengers that you are moving the car to a position where you can open the door and safely release them out. Instruct passengers to stand at the exit from the elevator door.

Determine the position of the elevator car, and check that the elevator car door and landing door are closed.

Prepare the tools needed to release the elevator brakes.

Cut off the main power supply of the elevator in the elevator machine room, and lock the power switch and tag it out when it is confirmed that the elevator power supply is completely cut off, so as to prevent unauthorized personnel from turning on the elevator power supply and causing danger to the personnel who are working and the passengers who are evacuating the car.

Check if the elevator car exceeds the nearest floor level position by 300 mm, when exceeded:

Notify trapped passengers that the elevator will be twisted or lowered normally, but there is no need to panic.

Referring to the schematic diagram of the on-site release brake, the brake release device is correctly placed on the brake magnet.

Use the handle on the brake release device to carefully apply uniform pressure to the brake brake to release the brake pads. When using the brake release device, one person must be responsible for controlling the brake release device and the other person must be responsible for controlling the rotating disc, so that the brake is always under control, and the brake can be braked safely and firmly immediately when needed.

Remind passengers again that the rescue work is in progress, and then evenly operate the brake release device and control the rotating disc to move the car several times, and only move the car about 30mm at a time. Don't rush or amplitude too much.

Through the above operation, it can be determined whether the car can move safely and the performance of holding the brakes.

Once you are confident that you have secured mobility, you can gradually increase the amount of movement. Use the manual release brake device to slide the car about 300mm at a time until the car reaches the nearest floor. Note:

The direction in which the car moves depends on the weight of the car and the counterweight.

By monitoring the floor markings on the wire rope, it is possible to identify when the car is in the leveling position. If there are no markings on the cable, another person must be assigned to monitor it.

Open the landing door with the designated pry door key to check the upper and lower gap between the car sill and the floor floor. If you are sure that the distance between the top and bottom does not exceed 300 mm, you can only open the car door to release the trapped passengers, note: For the safety of passengers when evacuating, two staff members must be assigned to assist passengers in evacuating the car before preparing to open the car door to release passengers.

When all passengers evacuate the elevator, the car door and landing door must be closed again and the brake lock must be fastened.

After each use of the elevator pry key, the pry key must be put back in place for safekeeping, and fill in the use record.

Finally, the process of releasing passengers will be reported in detail to the maintenance service center of the OTIS elevator company.

Do not try to pry the door after being trapped, do not hit the door, do not jump in the car, should press the panic button or call **for help.

When rescuing trapped people in elevators, the following practices are wrong.

a.Correct elevator to crank the car and loosen the brake to rescue the lead before the rescue to comfort the trapped people in the car, and signal the trapped people not to approach the car door.

b.Before the elevator is rescued, it is necessary to check whether the total power supply is disconnected.

c.In order to rescue the trapped people as soon as possible, there is no need to pay attention to what can be directly carried out to rescue the elevator brake.

d.When rescuing the elevator on the crank and loosening the brake, it is necessary to maintain the slag and communicate with the old personnel in the car to understand the situation in the car at any time.

Correct answer: c

The elevator trapped people for 2 hours is a special equipment accident. According to Article 64 of the Regulations on the Safety Supervision of Special Equipment: "If there is any of the following circumstances, it is a general accident: (3) the elevator car is stranded for more than 2 hours;

In any of the following circumstances, it is a general accident:

1) The special equipment accident causes less than 3 deaths, or less than 10 serious injuries, or direct economic losses of between 10,000 yuan and 10 million yuan;

2) Leakage of toxic media from pressure vessels or pressure pipelines, resulting in the transfer of between 500 and 10,000 people;

3) Persons stranded in the elevator car for more than 2 hours;

4) The main stressed structural parts of the lifting machinery are broken or the lifting mechanism falls;

5) Passengers stranded at high altitudes for more than 12 hours on passenger ropeways;

6) Persons stranded at high altitudes for more than 1 hour and less than 12 hours in large-scale amusement facilities.

In addition to the provisions of the preceding paragraph, the special equipment safety supervision and management department may make supplementary provisions for other situations of general accidents.

When a passenger is trapped in an elevator, immediately notify the elevator professional to arrive at the scene to rescue the trapped person. Before the technician arrives at the scene, the fire control room should carefully observe the situation in the elevator, and ask the trapped person through the intercom system and comfort him. If there are children, the elderly, pregnant women or people in the trapped person, special attention should be paid to the lack of oxygen supply, and if necessary, please ask the fire personnel to assist.

Do not frequently kick the door and knock on the door: if there is no alarm bell, ** or walkie-talkie, and the mobile phone is out of order, you can knock on the door and shout or take off your shoes and knock on the door to send a signal for help. If no one responds, wait calmly, observe the movement, do not keep shouting, maintain your physical strength, and wait for rescue.

The emergency rescue of the trapped person in the elevator should be rescued by the elevator professional.

Emergency rescue generally refers to the activities and plans for prevention, preparedness, response and recovery of sudden and destructive emergencies. According to the different types of emergencies, it is divided into emergency rescue in the fields of health emergency, traffic emergency, fire emergency, emergency response, factory and mine emergency, and family emergency.

In January 2020, Chongqing proposed to build four aviation emergency rescue bases in Yubei, Wanzhou, Qianjiang and Yongchuan.

Work objectives: made for infiltration emergencies; Control the occurrence and expansion of emergencies.

Carry out effective rescue, reduce losses and quickly organize a return to normalcy.

Rescue objects and basic tasks:

Public safety accidents, disasters and incidents with suddenness and serious consequences and impacts.

These accidents, disasters or incidents are mainly in the following areas: industrial accidents, natural disasters, urban clusters of lifelines, major projects, public activity venues, public transportation and other emergencies.

Immediately organize the rescue of victims, organize evacuation, or take other measures to protect other personnel in dangerous areas.

Quickly control the situation, monitor and detect the dangers and hazards caused by the accident, and determine the first hazard area, the nature of the hazard and the degree of maintenance of the accident.

Eliminate the harmful consequences and do a good job of on-site recovery; Identify the cause of the accident and assess the degree of harm.

The correct self-rescue method of the trapped elevator; Don't panic, keep calm, and show everyone that the elevator slot has an anti-fall safety device, which firmly clamps the rails on both sides of the elevator and will not fall. Eliminate everyone's panic.
