Weather is not just a topic of conversation for those who use an electric wheelchair. Rain may affect your plans for the day, and it raises real questions about safety and equipment damage. The quick answer is that most electric wheelchairs can handle light rain for short distances, but they are not designed for driving in heavy rain or puddles. Before you roll your power chair outside on a rainy day, here are some important things you should know.
Get the Hang of the Water Resistance Ratings
Most power wheelchairs have an IP rating that indicates how much water and dust the electronics can withstand. The IPX4 rating will be found on a spec sheet. That number translates to the chair being able to withstand water splashed from any direction, including light rain and puddle splashes from passing cars. This does not imply that the chair can be driven through deep water or submerged.
Some higher-quality power chairs have an IPX5 or IPX6 rating, meaning they can withstand more powerful water blasts and rain. Still, manufacturers do not often suggest using a wheelchair during continuous rain. The rating only covers the motor and battery casing, not the seat cushion, joystick control, or exposed wiring under the casing.
What Happens When Electric Wheelchairs Get Wet
Water and electronics don't mix well, and a wheelchair is full of sensitive parts. The three most susceptible areas to moisture damage are the joystick controller, the motor housing, and the battery terminals. If water gets in the controller, it can lead to short circuits or erratic speed changes you want to avoid.
Batteries face a different kind of risk. Most electric wheelchairs are equipped with sealed lead-acid or lithium batteries, and both can rust if water enters the terminals. Corrosion is a gradual process, and you may not notice it until weeks later when your chair starts to lose charge more rapidly than normal. Rust may also develop on metal joints of the frame and wheel bearings, reducing the chair's life even if the electronics are not lost. One rainy commute will not kill your chair, but a lot of them will add up quickly if not dried.
Practical Tips for Using Your Chair in Rain
When it's wet, a few precautions can make a big difference if you must go out. Avoid puddles, flooded curbs, and uneven pavement that pools water along your route. Standing water is much worse than falling rain, as it remains in place for longer against the motor housing and wheel hubs.
Here are some tips to take before and during a rainy trip:
- Make sure that battery covers and control panel seals are completely closed when you leave.
- Use a poncho or rain cape for wheelchair users that covers you and the upper parts of the chair.
- Do not use the chair controls with wet hands, as this may cause static or a short circuit.
- Have a microfiber cloth in your bag to clean the joystick and armrests when you're inside.
- Drive slowly on wet surfaces. Tires lose traction more quickly on painted crosswalks and metal grates.
These are not waterproofing measures, but they do help to minimize the potential for damage over time and help keep you safe on slippery pavement.
Waterproof Covers and Accessories
If you live in an area where the weather is often unpredictable, one of the best investments you can make is a dedicated wheelchair rain cover. They typically attach to the frame and hang over the seat, joystick, and battery pack, allowing you to steer hands-free. The cost of these covers varies from about 40 to 120 dollars, depending on the brand and the quality of the material used.
Some users also attach a canopy to the chair, similar to an umbrella attached directly to the chair. Canopies will keep light rain and sun off the rider, but will not prevent water from splashing up from the wheels during heavier rain. A combination of a canopy and a lower body cover or poncho provides more coverage than either accessory alone, and will provide year-round protection. Be sure to purchase a cover that fits the width of your chair's frame and the location of its controls, as a poorly-fitting cover can hinder steering or obstruct ventilation vents.
When to Avoid Using Your Wheelchair in Rain
Sometimes it's better to stay inside. Lightning is a hazard associated with thunderstorms, and if lightning strikes you while you are outside with a metal wheelchair, you could get an electric shock. Another obvious indicator to remain in place is flash flooding, which can impact the balance and electrical system of a chair even if it's just a couple of inches of moving water.
The risk of water getting through seals that are good for light splashing is also greater when it rains heavily for a long period of time. If a storm is expected to last several hours, it may be better to reschedule appointments than go through it. Icy rain and near-freezing temperatures also add to the danger as wet brakes and tires don't work as well in cold weather. Use your own sense of judgment. If it's bad enough for a driver to think twice, it's also bad enough for a wheelchair user.
Caring for Your Wheelchair After Rain Exposure
Once inside, a straightforward maintenance program will help keep your investment safe. Dry the frame, seat, and joystick with a towel. Take care to dry around seams and gaps where water may get in. For a few minutes, don't close the battery cover, allowing moisture to evaporate.
Check wheels and casters for debris that can be washed in with the rain, as small stones or grit can cause bearings to wear over time. If you see the chair moving slower than normal or the battery life decreasing over the next few days, don't wait to see if it improves - call a technician to check it out. Post-rain checks are only a few minutes long and can help identify minor problems before they turn into costly repairs.
Final Thoughts
Rain doesn't have to keep you at home, but it does call for some planning. Know the IP rating of your chair, buy a wheelchair cover, and don't go outside if storms get bad. You can continue to work in wet conditions without risking damage to your equipment or yourself with the proper precautions.
