- In recent 3 years and 11 months (Jan. 1. 2015 to November 20, 2015), there have been a total of 642 cases of elevator related cases received in the consumer risk monitoring system. 382 cases (59.5%) of the fingers were caught in the gap between the doors when the door was opened.
【 Elevator pincer accident 】
- The purpose of this study is to collect data on accident involving elevator hand injuries and to provide safety information to consumers and to improve related systems through investigation of elevator actual condition.
*In the event of a death, the first diagnosis by a physician conducted within 7 days from the occurrence of the accident has resulted in a person suffering an injury requiring more than one week of inpatient treatment or more than three weeks of treatment (Article 16-4 )
■ By typeBy type of accident, there were 379 (59.4%) accidents involving the hand between the elevator door and doorpost, 144 cases (22.5%) of confiscation caused by the breakdown, 96 cases (15% ), And so on. 【 Status by type of accident】 (Unit : Case, %)

■ Analysis of cause of accident ① Analysis of cause of accident A child who lacks awareness of danger and danger compared to adults is touched by the elevator door.. 【 Accident location of elevator accident 】
② Accident location of elevator accident Children's finger size characteristics : - The first node width is at least 4.67mm and the average width is only 7 ~ 8mm, so it is easy to get into the gap of the elevator door which is 6 ~ 10mm.
- The first node width is at least 4.67mm and the average width is only 7 ~ 8mm, so it is easy to get into the gap of the elevator door which is 6 ~ 10mm. ※ Europe ANEC * measures 20 ~ 35 children age and month by age in the study of prevention of child hand involvement **.
■ Actual situation survey • Survey period : 2015. 11. 18. • Investigation method : Field visit survey • Subject : Seoul's area is mainly used by children between 0 and 6 years old (kids cafes, pediatrics, child dentistry, etc.) and 60 apartment elevators • Measurement object and method : Measured using a digital caliper (1M point from the elevator floor) inside the elevator door
A. Gap spacing - (Relevant Standard) When the elevator door is closed, the clearance between the doors or the gap between the doors and doorposts, the door * or the threshold should be as small as possible to 6mm or less. However, up to 10 mm is allowed if worn.
*Crossing the elevator doorpost
※ In Europe, the gap of the elevator door made of glass is maximum 4mm and 5mm when it is worn.
- Of the 60 elevators surveyed, 24 (40.0%) were below 6mm, but 34 (56.7%) were between 7 ~ 10mm, and elevators with 11mm or more were 2 (3.3%).

B. Indication of hand pinch - Among the 60 elevators to be surveyed, there is no place where the handholding mark is attached. All elevators are marked with 'Do not touch' or 'Risk of falling down' sign, but it is difficult to recognize children under 6 years old (average height approx.
C. Hand-held sensor - None of the 60 elevators surveyed were equipped with safety devices that detected their hands and stopped door openings.
D. Safety status of glass doors - (Relevant standards) Elevators with glass doors should be opaque to a height of 1.1 m to prevent the danger of being dragged by children. - Three of the four glass doors of the elevator door are opaque to the glass lower than the standard.
*Stature) According to the Ministry of Education sample of 2013, the average height of 6-year-olds is 113.6 cm for men and 112.5 cm for women
■ Hand-held mock test
• Exam date : 2015. 11. 30. • Purpose of examination : Identify the risk of children's hands getting into the elevator door • Exam contents : Check the degree of hand-fit when opening the door with the model hand of a 5-year-old child in contact with the elevator door horizontally to the elevator door clearance • Test subject elevator: The same building, the manufacturer, the installation date Four elevators • Test Adviser: Accident Investigation Department of Korean Elevator Safety Personnel In the 4mm of the door gap, there was no pinch, but at 5mm or more, the pinch phenomenon appeared to occur from the edge of the base.【 Hand-piercing process sequence photo 】
- The larger the gap of the door, the larger the area of the finger, and when the gap of the door exceeds 9mm, the entire finger is completely caught.
※ When one finger is stuck, the gap of the door is widened and the other finger is caught.
- The current door gap standard is 6mm for installation and 10mm for installation but it is insufficient to prevent child's accident.
- During the opening of the elevator door, the guardian will recognize the finger of the child at first, and even if the closing button is pressed, the door will not be stopped or closed during the opening operation.*Hand) It is manufactured by Korea Elevator Safety Management Model with 5 years old child hand model. Size: 11.4 mm, second segment: 12.3 mm), index finger (first segment: 10.6 mm, second segment: 12.1 mm)【 Hand-held simulation test results 】
