Yes. Keep the helmet on for the whole ride, including the trip to the playground, and take it off the moment your child gets off the bike. The U.S. Consumer Product Safety Commission (CPSC) advises against helmets during play, above all on playground equipment, after two children died when their helmets stuck in playground openings and left them hanging. The danger is rare and entirely preventable, and the habit that prevents it costs a few seconds at every stop.
When the helmet is on and when it is off
| Situation | Helmet | Why |
|---|---|---|
| Riding the bike, including the ride to the park | On | CPSC wants a child helmeted on every ride. |
| Off the bike, even a few steps from the playground | Off | CPSC says the helmet comes off when the child gets off the bike. |
| Climbing frames, slides, tunnels and other play equipment | Off | CPSC’s alert and its playground handbook both advise against it. |
| Climbing trees | Off | Some of the no-injury cases CPSC knows of involved tree climbing. |
| Anywhere else once the ride is over (bunk beds, windows, trampolines) | Off | Three Australian child deaths in these settings involved helmets. |
Why a good helmet becomes a hazard on a climbing frame
Two things change when a bike helmet goes onto play equipment. First, the helmet enlarges the head. Head entrapment means a child’s head becomes stuck in an opening and the child cannot get free. CPSC’s Public Playground Safety Handbook (2010 edition) calls it a serious concern because it can lead to strangulation and death, and it flags gaps between about 9 and 23 cm (3.5 to 9 inches) across as the danger zone. The same handbook reports helmeted children getting trapped in gaps not normally treated as a head-entrapment hazard. The Bicycle Helmet Safety Institute (BHSI) passes along a playground-standards official’s remark that equipment openings were designed around bare bodies, not bodies wearing helmets.
Second, the helmet comes with a strap. BHSI describes two ways this has gone wrong. It reports that a Pennsylvania boy died in February 1999, apparently wedged between overlapping horizontal platforms: his body had slipped through the gap but his helmeted head could not follow, and as the lower part of his body hung, pressure on his chest kept him from breathing. In the Canadian and Scandinavian incidents BHSI describes, the helmet strap itself strangled the child.
Young children are the least able to get out of trouble. The handbook notes that they may lack the understanding or coordination to undo whatever trapped their head, especially if scared or panicked, and that even low openings, where a child’s feet can touch the ground, can strangle an entrapped child.
CPSC’s alert counts two strangulation deaths when helmets stuck in playground openings, plus four cases with no injury: two children climbing trees and two on playground equipment. BHSI dates CPSC’s warning to 1999, so treat these counts as evidence the hazard is real and rare, not as current statistics.
It is not only playgrounds
A letter in the Medical Journal of Australia reports a search of the national coroners database, which covers every state and territory, for child deaths between 2001 and 2009 that involved bicycle helmets. It found three young children who died hanging from their helmets, none of them while riding a bike:
- a 2-year-old boy hanging by his helmet strap in the space between his bunk bed and the wall (2003);
- a 3-year-old boy hanging by his strap while trying to get out through a window at home (2007);
- a 5-year-old boy left hanging from an overhead clothesline as he bounced on a trampoline (2009).
The authors note that these hangings can happen away from playgrounds, sometimes in unusual ways, and advise that children wear bicycle helmets only for their intended purpose. The rule: the helmet is for riding, and it comes off when the riding stops, wherever that happens.
A routine for every stop
- Unbuckle before the child heads for the equipment, not after they are already on the frame. If your child rides in a seat or trailer, do the same when you lift them out; our guide to child seats, trailers and cargo bikes covers those setups.
- Put the helmet out of play, hung on the handlebar or tucked in a bag.
- Check the rest of the outfit. Safe Kids Worldwide says to take off necklaces, purses and scarves and to avoid drawstring clothing, since these can snag on equipment. The CPSC handbook adds that children have died when clothing drawstrings caught on slides or other equipment, and says to remove hood and neck drawstrings before play.
- Stay close. Safe Kids advises active supervision. A trapped young child may not be able to free themselves, so staying near enough to act at once matters most.
- Put the helmet back on before the wheels turn, with a snug strap. Our guides to how helmets work and buying a helmet help with choosing one.
What about falls from the equipment?
Parents hesitate because falls are a fair worry: the handbook’s cover note says falls remain the largest single hazard pattern on playgrounds. CPSC’s answer, though, is the ground rather than a bike helmet. Since its first edition, the handbook has recommended against building playgrounds over concrete, asphalt or other paved surfaces, to reduce serious head injuries from falls.
Safe Kids recommends sand, pea gravel, wood chips, mulch or shredded rubber, at least 30 cm (12 inches) deep and extending at least 1.8 m (6 feet) in every direction around stationary equipment. Report hazards at a public playground to whoever runs it. For a backyard set, BHSI suggests checking the equipment against the ASTM playground standard, particularly if it is old or locally made.
The trade-off, and where the sources differ
A strong strap is what keeps a helmet on during a crash, and BHSI is open that this makes the issue a balancing act. In 1999 the ASTM headgear standards subcommittee discussed the playground problem, and BHSI reports that its members judged that weakening buckles to guard against rare strangulation cases would harm many more riders than it helped, because infants and children could lose their helmets in a crash. So the answer is not skipping the helmet on the bike. Never loosen or modify a helmet’s strap or buckle for playground use; remove the helmet instead.
BHSI also says CPSC was wary of putting parents off helmets, since a child faces more risk riding to the playground than being trapped once there. For the ride itself, see our basic rules of cycling on roads.
BHSI says it has heard that at least one Swedish manufacturer believes many children have avoided serious injury, on playgrounds and elsewhere, because they had a helmet on, and it calls the balance of risks “not easy.” CPSC’s alert, CPSC’s handbook and Safe Kids nonetheless give the same advice: take it off for play.
If a child gets caught: stop and get help
If a helmet or strap catches a child on playground equipment, in a tree or anywhere else, and the child is hanging, struggling to breathe or cannot get free, call your local emergency number immediately, or have another adult call, while you work to take the pressure off and free them. Do not wait to see whether they recover. Even if the child seems fine afterward, have a medical professional check them.
