Using a stair chair incorrectly can result in dropped patients, back injuries to operators, and equipment failure. Most mistakes happen not during the descent itself but in the moments before and after: skipping straps, failing to communicate, ignoring the condition of the stairs, or storing the chair in ways that degrade it over time. Here’s what to avoid.
Never Skip or Partially Apply the Restraints
A stair chair has two separate sets of restraining straps for a reason: one across the chest and one across the lap. Both must be secured every time. Skipping the chest strap because “it’s only one flight” or leaving either strap loosely buckled is one of the fastest ways to eject a patient during a descent. To attach each strap, pass it around the frame, thread the free end through the loop on the opposite side, and pull it snug. A strap that’s buckled but slack offers almost no protection if the chair tips or shifts suddenly.
Check that the straps themselves aren’t frayed, torn, or missing before you load anyone into the chair. Damaged straps won’t hold under the sudden force of a stumble.
Don’t Stay Silent on the Stairs
The single biggest communication mistake is assuming your partner knows what you’re about to do. Stair chair descents require constant verbal coordination between the person at the top and the person at the bottom. Call out each step, announce turns, and confirm you’re both ready before changing direction or pace. “Stepping down,” “hold,” and “turning left” are the kinds of simple, loud cues that prevent the jerky, uncoordinated movements that lead to falls.
Silence during a carry is dangerous. If one operator speeds up while the other slows down, the chair tilts unpredictably. If you’re approaching a landing or a turn, say so before you get there, not while you’re in the middle of it.
Don’t Use It on Unsuitable Stairs
Not every staircase is safe for a stair chair. Spiral staircases, extremely narrow stairwells, and stairs with uneven or broken treads all create hazards that the chair wasn’t designed to handle. Wet or icy outdoor steps are especially risky because the chair’s treads lose grip on slick surfaces. Before starting a descent, take five seconds to look at the stairs themselves. Loose carpet, missing handrails, objects on the steps, and poor lighting all need to be addressed or accounted for before you load a patient.
If you’re using a powered or tracked stair chair, the track system needs a relatively consistent stair surface to operate correctly. Debris, gravel, or transitions between different flooring types can catch the tracks and cause a sudden stop or jolt.
Don’t Forget the Pre-Use Inspection
A stair chair that worked fine last week may not work fine today. Before each use, check the frame for loose bolts, cracks, or visible damage. Test the wheel locks and brakes. Inspect the tracks (on powered models) for dust, dirt, or debris that could jam the system mid-descent. If you find any unsafe condition, the chair should come out of service until it’s repaired.
This sounds obvious, but in the urgency of a call, pre-checks get skipped constantly. A brake that doesn’t engage or a wheel that wobbles is far worse to discover on the third step than in the back of the ambulance.
Don’t Try to Carry Too Much Weight Alone
Stair chairs have rated weight limits, and those limits exist for both the patient’s safety and yours. Exceeding the capacity stresses the frame, the straps, and the operators. Even within the weight limit, a stair chair descent should always involve at least two people. Attempting a solo carry, even for a lightweight patient on a short staircase, removes your ability to stabilize the chair if something goes wrong.
Your body mechanics matter, too. Bending at the waist instead of the knees, twisting while lifting, and gripping the handles with extended arms all increase your risk of back injury. Keep the chair close to your body, bend your knees, and let your legs do the work.
Don’t Rush the Descent
Speed is the enemy on stairs. Taking steps too quickly reduces your reaction time if the chair shifts, a strap slips, or the patient moves unexpectedly. Move one step at a time and pause briefly on each tread before continuing. This controlled pace gives both operators time to adjust their grip, maintain balance, and communicate. A smooth, slow descent feels more stable for the patient, too, which reduces the chance they’ll panic and grab at their surroundings or lean suddenly.
Don’t Store or Clean the Chair Carelessly
What you do after the call matters for the next one. Harsh chemical cleaners can corrode the finish and damage mechanical parts. After cleaning, dry the chair completely to prevent rust and moisture buildup in joints and track systems. When folding the chair, follow the manufacturer’s instructions exactly. Forcing it into the wrong position can misalign hinges and weaken the frame’s structural integrity over time.
Store the chair upright in a clean, dry location away from direct sunlight and temperature extremes. Don’t stack heavy equipment on top of it. Weight on the seat and frame causes gradual distortion that may not be visible but compromises the chair’s ability to support a patient safely. Keep the tracks clear of accumulated dust and debris between uses so the system operates smoothly when you need it.
