How does a choke tester tool work?

The choke tester tool is an exact replica of the small parts cylinder used in the European Safety Standard (EN71). If an everyday object or toy fits completely inside the tube without forcing, or can compress to fit, it is classified as a choking hazard for babies and children under three.

At what age should parents start using a choke tester?

You can start using it from around 3 months, or as soon as your baby begins reaching, grasping, and exploring objects by mouth. It is especially useful before your baby starts crawling to audit floors, under sofas, and low storage.

Does a £2 coin fit inside the choke tester tube?

Yes. A £2 coin easily fits inside the tube, surprising many parents and clearly demonstrating that dangerous choking hazards can be much larger than commonly assumed.

Is the choke tester tool suitable for teaching older siblings?

Yes. It acts as an easy visual reference for older brothers and sisters, helping them independently test their own small toy parts (like building bricks, marbles, and doll accessories) to determine what must be kept away from younger siblings.

How to use your Choke Tester

Don't leave safety to guesswork. This tool makes it crystal clear what items need to be moved out of your child's reach.

If it fits, it's a hazard

Simply drop everyday items into the cylinder. Coins (even large £2 coins), buttons, beads, screws, lithium batteries, and pen tops are all common hazards. If it fits completely inside, keep it out of reach.

Educate older siblings

If you don’t know the exact size of a choke hazard, how can you explain "small" to an older child? Giving them this tester turns safety into a fun game, helping them figure out for themselves which toys must be kept away from the new baby.

Mind the shape

While this tool is brilliant for small parts, remember that shape matters too! Long, slippery foods like hot dogs, or perfectly sized objects like poorly-designed corner protectors, can still be hazards even if they don't fit perfectly.

🛡️ Essential baby-proofing starts here

Helping the whole family "think safe".

"You will naturally focus on keeping your baby's cot safe, but as soon as they start crawling, they will spot things on the floor you didn't even know were there. Dropped coins, burst balloons, or a stray marble can roll under a sofa instantly. Having a physical Choke Tester in the house acts as a visual wake-up call for parents, carers, and siblings alike."

Your questions, answered

When should I start using this?
Right away! Even before your baby starts crawling, it is so easy for coins, buttons, or sweets to fall out of a pocket and for a baby to find them while cuddling on the couch.

Does a £2 coin really fit?
Yes, it does. Many parents are shocked to discover that objects as large as a £2 coin or certain small toy figures easily slip into the European Standard small parts cylinder.

Is this just for toys?
No, it's for everything! It's especially useful for auditing your home before a baby starts moving. Check under every cupboard, sofa, and bed in every room your child has access to.
