According to Emirates 24/7, a Filipino worker at a restaurant in the Salimiya neighborhood of Kuwait City lost some of his fingers after they became caught between the elevator and the elevator door on Monday, March 4, 2013.
Kuwait police described the elevator as “lacking minimum safety standards”, and the article notes that emergency personnel “had to smash the lift’s door” to release the man. Read the reporting article, published March 4, 2013.
Typically, elevators have door reopening devices such as “safety edges” or “scanner edges” which detect obstructions in the path of the door. A “safety edge” is typically a rubber bumper that retracts when it comes into contact with an obstruction. A “scanner edge” uses beams of light to detect when a beam is interrupted by an obstruction. However, even when these devices are present, there is still the possibility that something as small as a human finger could become entrapped between the outer hoistway doors.
Generally speaking, door entrapment accidents result in severe injuries if the elevator runs while the unsafe condition exists. Similar door entrapment incidents have occurred in the past when garments such as scarfs become entrapped and the elevator runs, leading to strangulation.
According to Indian news agency DNA (Daily News & Analysis, an 18 year-old girl was crushed to death Wednesday, January 9, 2013, after she entered the hoistway, apparently to sweep the pit. The report is somewhat unusual in that it specifically describes that the motor of the “old lift” somehow crashed down on top of her, fatally crushing her. The victim died at the scene. An employee at the building who was not named described the building as “dilapidated”. A comment on that article also notes that there may have been other similar incidents at that location.

Incidents like this highlight why it is important that access to elevator pits, hoistways, and machine spaces is restricted to elevator personnel only. It is not yet clear how the victim was able to access the pit, however, the original news report indicates that it was apparently part of her “sweeping duty” to sweep the pit. In the United States, building maintenance and housekeeping staff are generally prohibited by code from entering these restricted spaces. Cleaning of the pit should be part of the maintenance control program followed by the elevator contractor during periodic preventive maintenance visits.
According to ABC 7 Eyewitness News, an 85 year-old man was left in critical condition after an elevator in his public housing apartment building crushed both his legs around 5 p.m. Sunday, December 30, 2012. Firefighters reported that when they arrived, the elevator was stuck between the first and second floor, with the man’s body inside the cab, and his legs dangling outside the cab on the first floor. Firefighters used air bags and other extrication methods to free the man’s legs and pull him up into the elevator cab. The victim was rushed to nearby Harlem Hospital where he was listed in critical condition, with both of his legs fractured.

Interestingly, this is the third consecutive year in which a passenger was seriously injured or killed by an elevator in New York City that moved with the doors open during the month of December. On December 25, 2010, a woman was seriously injured at SUNY Downstate Medical Center when an elevator ascended unexpectedly while she was in the open doorway, and on December 14, 2011, Suzanne Hart was fatally crushed under similar circumstances. In both of those cases, an elevator mechanic was found to have used a wire jumper to bypass the elevator’s door interlock and gate switch safety circuits. Although there is no information yet as to what caused this incident, given that the firefighters described the man’s legs as “dangling outside” the elevator, it is very likely that the elevator moved while its doors were still open, and while the man was within the door threshold. It is not yet clear why the elevator would have moved while the doors were still open. The Department of Buildings will likely conduct an investigation and we will publish the results of that investigation when that information becomes available to us.
The New York City Housing Authority is notably the single largest operator of elevators in the City of New York, and is responsible for over 3,300 elevators in nearly 2,600 residential buildings, serving over 400,000 residents. The reliability of elevators in New York City’s public housing has long been a sore point with residents. A memorable New York Times article published March 12, 2005 famously opened with, “Up, up, up it rises, this elevator redolent of urine, groaning toward the rooftop of another tired building in the Queensbridge public housing development, the largest in Queens, in New York, in North America.” On June 12, 2012, the New York City Housing Authority reached a settlement with tenants in a class action lawsuit that alleged the Housing Authority let its fleet of elevators fall into “widespread disrepair and dysfunction.” The case is Brito v. New York City Housing Authority, in the U.S. District Court for the Eastern District of New York, No 09-1621.
According to the Kuwait Times, an elevator accident left one elevator mechanic dead and another seriously injured in the Sabhan neighborhood of Kuwait. Although details of the circumstances are scant, it appears that both mechanics were working in the hoistway pit of an interior ministry building at the time the accident occurred. The elevator unexpectedly descended, crushing the two men, killing one instantly. Read the full story by the Kuwait Times, published December 27, 2012.
In the United States, elevators have long been required to have stop switches in the pit to prevent unexpected movement of the car when working in the pit. It is standard procedure to ensure that the elevator is under control before entering the pit or accessing the car top. Crushing accidents involving the pit often involve improperly trained personnel accessing the pit, for example to retrieve dropped keys. However it is critical that only properly trained elevator personnel enter the pit, to prevent this type of incident. It is not clear whether or not the elevator in this incident was equipped with a stop switch in the pit, or whether the mechanics had followed procedures to gain control of the elevator before entering the pit. We will update this story if more details emerge.
According to the New York Post, the superintendent at a building in Washington Heights was seriously injured Thursday, August 16, 2012 when he was struck in the head by an elevator counterweight. The victim, whose name was not immediately released, went in the pit around 8:40 a.m. in order to retrieve keys that a tenant had accidentally dropped through the gap between the floor sills. The elevator had apparently ascended to the sixth floor as the counterweight descended into the pit, striking the victim’s head. Read the full story by the New York Post.
A later article by DNAinfo.com New York reported that the building’s managing agent, Bronstein Properties LLC, identified the victim as Armando Bennett. Bronstein Properties’ spokesman Joe Masino noted, “I don’t allow my supers to go down the shaft, [they] should call the elevator company.”
If the spokeman’s statement is accurate, then it is not clear how the superintendent opened the hoistway door in order to gain access to the pit, unless it was a walk-in pit, which it does not appear to be given that the victim was describing as doing “down the shaft” to access the pit. Based on the media accounts of the accident, it appears that the victim may have entered the pit without first gaining control of the car, for example, via the stop switch in the pit. Assuming the superintendent entered the pit without gaining control of the car, and the door closed behind him, the elevator would resume automatic operation, for example, responding to the a sixth (top) floor call, which would have then sent the counterweight into the pit at full speed.
Possession of hoistway door keys is restricted by ASME A17.1 Rule 8.1.2, which covers Group 1, “Restricted” keys. Keys in Group 1 are restricted to elevator personnel only. Unfortunately it is all too common that unauthorized individuals obtain hoistway door keys. This accident serves as a reminder that an elevator hoistway is one of the most dangerous areas in a building, and only properly trained elevator personnel should ever access the hoistway. If an object falls into the pit, it is critical to wait for elevator personnel to retrieve the item to prevent injuries like this.
According to NBC New York, an 11-year old boy fell three floors down an elevator shaft around 12:30pm on Sunday, December 9, 2012. According to police, the victim and other young boys were playing in the building hallway when “the elevator doors unexpectedly opened and one of the boys fell in”. The condition of the boy was not immediately clear, but presumably the boy was hospitalized and sustained serious injury.
The description of the incident according to police and according to NBC New York indicates that the boy was rescued through the roof of the elevator car. Given that, the elevator doors could not have “unexpectedly opened” in the sense that the doors themselves opened. Rather, based on the description of the accident, involving boys playing in the hallway, it appears that the victim likely struck the door with force, causing the door gibbs to fail, causing the lower retaining door gibbs to break away, thus allowing the bottom of the hoistway door to swing open into the hoistway enough to allow the boy to fall into the open hoistway.
This is similar to the case in which a wheelchair-bound man in Korea crashed his motorized wheelchair into elevator doors, causing the door gibbs to fail, and causing the man to fall into the hoistway. Interestingly, Korea requires that hoistway doors bear a sign with a pictograph that depicts the hazard created by leaning on, or otherwise applying force to, hoistway doors. This appears to be a case in which the hoistway door was forced to bear excessive forces and ultimately failed, exposing a member of the public to the potentially fatal hazards of the hoistway.
According to News Limited, “a male office worker died on Monday afternoon ‘after getting stuck in a lift that suddenly descended’, a police spokesman said.” Although the exact circumstances remain unclear, it appears that the man was a deliver worker who was transporting something from one floor to another. Apparently the item he was moving became stuck in the gap between the cab and the floor landing. The man was then standing in the sill, with one foot in the car, and the other foot on the landing, when the elevator suddenly descended, apparently crushing the man.
According to the Times of India, a 55-year-old man died and two people were seriously injured when an elevator cable snapped in a marriage hall in Korrukkupet on Sunday afternoon. According to the report, the elevator plunged from the third floor to the ground floor after the cables gave way. It was unclear at the time of the report whether overspeed governors or other types of safety devices are required by any applicable elevator codes in India, however, according to the article, the elevator was only six months old.
According to that article, the victims were riding the elevator when it stopped suddenly and entrapped the victims. The victims signaled for help, and in an effort to free the entrapped passengers from the elevator, untrained employees of the wedding hall apparently went into the motor room and released the elevator’s brakes, sending the elevator into a free fall. Normally, the counterweight will cause the counterweight, not the elevator cab, to free fall, however, it is possible that with the weight of four or more passengers that the counterweight’s balance might be exceeded, causing the elevator to fall downwards when the brakes were released. Interestingly, the article notes that if the employees had “phased” (or stuttered) their release of the brake, the elevator would not have fallen and the victims would not have been injured.
The New Indian Express article also includes a quote from an official that investigated the accident that described the situation:
“In their anxiety to quickly bring the occupants of the lift out, men who were not properly trained or authorised to handle the system released the lever without realising that it could lead to a free fall.”
According to the Siloam Springs Herald Leader, “A 50-year-old man was dropped three stories when the passenger elevator he was riding inside the Simmons Feed Mill in Decatur failed Friday morning.”
According to Pittsburgh, Pennsylvania news agency TribLIVE, Black Friday shopping was interrupted at Century III Mall in West Miffllin after an elevator motor caught fire for yet-unknown reasons. Interestingly, an elevator maintenance technician apparently discovered the fire when he noticed heat coming from the motor room.
According to the article, a fire official said the motor and its oil burned within the elevator shaft. No one was injured, but the store and businesses around it were cleared while fire crews remained on scene.
