Dira se jaanong¶

1. Tobetsa konopo e khibidu ya Emergency Stop kwa lefelong le le kwa godimo kgotsa le le kwa tlase ka bonako: Fa setlhako sa mongwe le mongwe, diaparo, kolotsana, kgotsa seatla sa gagwe se ka tshwara mo escalator kgotsa mo tseleng e e tsamayang, goa "Tobetsa konopo e khibidu ya go ema" mo bathong ba ba lebileng kwa lefelong la go kotama fa o ntse o taboga go e tobetsa ka bowena.
2. Tlhagisa bapalami go tshegetsa ditshwaro tsa diatla pele ba tobetsa stop: Go tobetsa konopo ya go ema ka tshoganyetso go kgaola maatla a enjene mme go tsenya boriki jwa motšhini, go tlisa ditepisi go ema ka bonako mo go ka dirang gore bapagami ba ba emeng ba ba sa tshegediwang ba ye kwa pele; goa "Tshwara setshwaro sa letsogo, emisa escalator" fa o ntse o itaya konopo.
3. Slip your bare foot out of a trapped shoe or cut a snagged shoelace: If your shoelace, boot, or soft rubber clog is caught between the moving step and the side skirt while moving toward the landing, pull your bare foot straight out of the shoe or rip/cut the lace immediately before the step reaches the comb plate teeth.
4. Never try to pull a trapped limb straight out once the escalator stops: If fingers, toes, or soft tissue are wedged beneath the comb plate or inside the side skirt gap after the machine halts, pulling forcefully will tear skin and nerves (degloving); support the limb still and wait for Fire and Rescue technical extrication.
5. Call emergency services and ask for Heavy Rescue and EMS: Dial your local emergency number (911 in the United States and Canada, 112 across the European Union, 999 in the United Kingdom, or see our dinomoro tsa tshoganyetso directory) and report an active escalator mechanical entrapment so firefighters bring hydraulic spreaders and socket tools.
6. Never walk onto a stopped escalator that is undergoing maintenance: A stationary escalator with removed step treads or an disengaged main brake can suddenly roll backward under passenger weight like a runaway treadmill, dropping riders into the open steel drive truss pit.

Escalator anatomy: the 4 mechanical entrapment zones¶

Understanding where and how escalators and moving walkways trap footwear, hands, and garments helps riders avoid high-risk positions and helps bystanders identify where to stabilize a casualty.

Why soft foam clogs and flexible rubber boots are uniquely vulnerable¶

Over the past two decades, pediatric trauma centers and elevator/escalator safety regulators worldwide have documented thousands of severe foot entrapments involving soft, pliable ethylene-vinyl acetate (EVA) foam clogs and thin flexible rubber rain boots.

Hard leather dress shoes and firm athletic soles maintain their structural shape when they brush against the stationary steel skirt wall of an escalator. In contrast, soft foam clogs and thin rubber boots combine two dangerous physical properties: an exceptionally high coefficient of sliding friction against steel (creating grab rather than slip) and low compressive stiffness. When a child stands at the far edge of a step and brushes the toe or side of a foam clog against the stationary side skirt, friction drags the soft foam backward and downward, stretching and rolling the thin rubber like dough into a gap only 3 to 4 millimeters wide. Because the foam compresses easily, it bypasses the skirt deflection safety switches until the child's toes are pinned deep between the descending step riser and the steel wall.

1. Controlling severe bleeding from serrated step lacerations¶

The sharp 90-degree edges of cast-aluminum escalator treads act like cheese graters when a person falls down a moving staircase, frequently slicing deep parallel tracks across the shins, knees, forearms, and scalp.

• Press a thick pad of clean gauze or a folded clean cotton shirt directly over the bleeding wound using both hands. See our guide on severe bleeding for complete hemorrhage protocols.
• Because escalator grooves are coated in industrial chain grease, carbon dust, and street dirt, do not try to scrub grease out of deep open wounds at the scene; focus strictly on stopping blood loss and letting hospital trauma surgeons irrigate and debride the tissue under anesthesia.
• If a major artery in the lower leg or forearm is severed and continues spurting bright red blood through direct pressure dressings, apply a commercial windlass tourniquet 5 to 8 centimeters (2 to 3 inches) above the wound (never directly over the knee or elbow joint) and write the exact time of application on the casualty's forehead.

2. Managing degloving injuries (skin and subcutaneous tissue avulsion)¶

When a rubber shoe or bare foot is drawn between the moving step and stationary skirt, the shearing force frequently strips the skin and underlying fat layer away from the deeper muscle fascia and tendons, like peeling off a tight glove.

• Preserve every millimeter of attached skin: If a flap of skin is peeled back but still attached by a tissue bridge (pedicle), never cut it off or fold it backward. Gently lay the skin flap back over the raw tissue bed in its normal anatomical alignment so the blood vessels in the pedicle are not kinked.
• Cover with sterile moistened gauze: Place sterile saline-moistened gauze (or clean non-stick dressings moistened with clean bottled drinking water) gently over the degloved area, followed by a loose dry outer wrap to prevent evaporative cooling and tissue desiccation.
• Immobilize and keep neutral: If the foot or ankle was compressed inside the mechanism for more than 15 minutes, screen for kgobalo ya go thubaganngwa le bolwetse jwa phaposi and keep the limb supported at heart level.

3. Preserving amputated toes or fingers for microsurgical replantation¶

If toes or fingers have been completely sheared off by the comb plate:

1. Treat the patient first, the amputated part second: Dress the bleeding stump with bulky sterile gauze and firm direct pressure.
2. Never reach your own hand inside the escalator comb plate to retrieve a severed digit: Tell arriving firefighters that a digit is inside the step return pan so they can unlock the inspection floor plate safely after locking out power.
3. Follow the three-layer cold preservation method:
   • Gently rinse gross loose dirt off the amputated part with sterile saline or clean bottled water (never scrub it or use antiseptic soap or alcohol).
   • Wrap the digit in a layer of sterile gauze lightly moistened with saline or clean water.
   • Seal the wrapped digit inside a clean, dry, watertight zip-top plastic bag.
   • Place that sealed plastic bag inside a second container or bag filled with a mixture of crushed ice and water. Never place an amputated finger or toe directly onto bare ice or dry ice, as direct freezing destroys microvascular cell walls and makes surgical reattachment impossible.

The catastrophic danger of escalator step collapse and truss pit falls¶

While rare compared to shoe entrapments, structural step failures and inspection floor plate collapses represent the most lethal class of escalator accidents. Underneath the thin loop of moving aluminum steps lies a deep, cavernous steel trough (the truss) containing the main drive motor, bull gears, step return chains, and rotating shafts at the top and bottom landings.

• Warning signs of an impending step-chain jam ("runaway" or buckling steps): If you hear a loud metallic grinding, rhythmic banging, or screeching sound coming from the steps, or see a step tilting upward at the edge as it approaches the landing, do not step onto the escalator. If you are already on the staircase when steps begin buckling and piling up at the landing like an accordion, grab both handrails immediately, pull your feet up onto the solid plastic/metal side deck beside the steps if narrow enough, or vault over the low side handrail onto the adjacent fixed staircase if positioned safely next to one.
• Never step over a yellow maintenance barricade onto a stopped escalator: When mechanics remove two or three aluminum steps to service an escalator, a yawning 1.5-meter (5-foot) vertical hole opens directly into the steel gear pit below. Worse still, when the main drive brake is mechanically released for servicing, a stopped escalator is held only by friction. If a group of commuters ignores a barricade and walks onto the stopped stairs to use them as a regular staircase, their combined downward gravity weight can overcome static friction and cause the entire metal staircase to accelerate rapidly downward in reverse (an escalator direction reversal), dumping dozens of people into a pile-up at the bottom landing or into an open maintenance pit.

Prevention: 6 high-impact escalator safety rules for families¶

Preventing escalator and moving walkway injuries requires strict habits whenever riding with children, luggage, or mobility aids:

• Stand inside the yellow perimeter border lines: Modern escalator steps have bright yellow plastic or painted boundary lines around all four edges of every step. Train children to always plant both feet strictly in the center of the step inside the yellow box, keeping soft rubber shoes and clogs at least 5 centimeters (2 inches) away from the stationary side skirt wall.
• Le ka motlha o se ke wa tsaya dikolotsana tsa masea, di-pushchair, ditulo tsa maotwana, kgotsa dikolotsana tsa morwalo tse di nang le mabili a mane mo escalator: Kolotsana e e mo escalator e e nang le dikhutlwana e ikhutsa ka maotwana a yone a a kwa morago mo legatong le le lengwe le le tsamayang fa maotwana a yone a a kwa pele a lepeletse mo moweng kgotsa a ikhutsa mo angleng e e kwa godimo ga kgato. Fela fa dikgato di setse di le sephaphathi fa go kotama kwa godimo kgotsa kwa tlase, kolotsana e boela kwa morago kgotsa e latlhela lesea le lebile kwa pele mo dikgatong tsa aluminiamo tse di nang le dintlha, kgotsa maotwana a mannye a a kwa pele a tshwaragane ka tlhamalalo mo diphatlheng tsa dipoleiti tsa kama. Ka metlha tsaya lifiti when pushing a stroller, wheelchair, or heavy luggage cart.
• Never allow pets to walk directly on escalator steps: A dog's paw pads, toenails, and fur have no rigid sole protection and are drawn straight into the 3-millimeter comb plate teeth at the exit landing, causing horrific multi-paw amputations. Always carry small dogs in your arms on an escalator, or take the stairs or elevator with medium and large dogs.
• Hold children's hands and make them step over (not slide across) the comb plate: Never let young children sit down on escalator steps, play near the bottom handrail inlet brush, or "ski" their rubber shoes off the final comb plate. Teach them to lift their foot high and step completely over the metal comb teeth onto the solid floor.
• Gather long garments and check shoelaces before boarding: Before stepping onto the entry landing, glance down to verify both shoelaces are double-knotted and lift the hem of any floor-length maxi-dress, abaya, sari, coat, or scarf at least 10 centimeters (4 inches) above your shoes.
• Keep moving forward immediately upon exiting the landing: Never stop at the immediate exit of an escalator or airport moving walkway to check your phone or look for gate signs. The machine continuously delivers 90 to 120 passengers per minute directly behind you; stopping at the comb plate causes an immediate chain-reaction human pile-up into the moving metal teeth.
