Building Safe Toys
Posted: Tue Dec 30, 2008 2:39 pm
Hi Guys,
Toys are great woodworking projects for a lot of reasons not the least of which is that they are fun to make, fun to give, and fun to watch being played with by a favorite child (or more than one).
We had a thread recently on the forum concerning making toy building logs. There was some good discussion, most of it concerned with safety in one form or another such as safe woods and finishing materials to use, and appropriate ages based on the size of the toy's parts.
We all want the toys that we make (or buy) to be safe to play with. I was curious, so I took a look at some of the government's Consumer Products Safety Counsel toy testing procedures. I am not an expert in this area by any means, and the actual testing requirements have many additional details, but here are some of my personal observations based on what I saw.
Some important things to consider:
Small Parts Test (Toys intended for children under 3 years of age)
Using the government's “Small Parts Cylinder”, do any removable parts fit entirely in the cylinder?
For example, the smallest of the toy building logs could possibly fail this test.
NOTE: Some toy safety groups feel that the standard Small Parts Cylinder is too small to adequately protect young children from choking hazards and suggest that parents use the cardboard tube from a roll of toilet paper as a test device. Also please note that there are separate stricter requirements for small balls 1.75” in diameter or less.

Pointed Parts or Sharp Edges
This may not be as much of a problem for wooden toys as for those made from plastics and metal, but is still a concern especially if the wood splinters, or if fasteners such as nails, brads, or wood screws are used in assembling the toy.
Use and Abuse Tests
What would my handcrafted wood toy look like if:
1. I dropped it four (4) times onto the concrete floor of my shop from a height of three (3) feet? (Note: This impact test is for toys weighing about 10 lbs or less. There are Tip Over Tests for larger toys.)
2. I twisted every part of the toy that can be grasped between my thumb and forefinger (or that I can get my teeth behind) with a torque of 3 to 4 inch-pounds? and...
3. If I then pulled on the same parts that I just twisted with a force of 15 lbs?
4. I set my toy on the shop floor and applied a dead weight of 25 to 30 pounds to my toy?
Did any pointed parts or sharp edges develop after any of these “use and abuse” tests?
Did anything fall off? (If it did, and the toy is intended for the “under three crowd”, I will need to go back to the Small Parts Test with the broken pieces.)
Strings and Rope
I didn't see this mentioned in the CPSC tests, but some experts say no cords, or cord lengths less than 6 or 12 inches for toys for infants and young children.
-----------
I thought I would share this as “food for thought” for all of us toy makers out there, not to discourage anyone from building toys, but maybe to give some insight into how to best design and assemble them.
I'm sure there are other things to consider that I didn't mention. If anyone has comments, corrections, or other suggestions on this topic please add them!
Maybe one of our Sketch-up capable folks could build a standard Small Parts Cylinder model.

Dennis
