This safety assessment covers the five wooden blocks in the Yuyu Curious starter kit (toy identification no. 20210101, 20210102 and 20210103) which we define as toys. The assessment shall address, in accordance with DIRECTIVE 2009/48 / EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL, “the chemical, physical, mechanical and electrical properties, flammability, hygiene and radioactivity hazards that the toy may pose and the potential exposure of the child”.

Chemical evaluation

Yuyu blocks do not use hazardous chemicals. The surface of wooden blocks is done with Osmo top oil or similar oil, which is a paraffin-based natural oil. After drying, the surface treated with Osmo Top Oil is safe and pleasant to handle. It is very resistant to conventional household chemicals and colorants such as juice, cola drinks, coffee, tea, milk, beer and wine. The product meets the requirements of EN 71.3 (Toy Safety) and EN 1186 5/14.

Kiilto B3 wood glue is used to glue the parts of the product together. Because of the glue, care should be taken to avoid putting the toy in the mouth and with young children, it is appropriate to use the toys together with an adult. Product Safety Data Sheet.

Hazardous health effects:

Ingestion:

The blocks are of a size that can not fit through a child’s throat (3cm*6cm). More precise sizes can be presented upon reasonable requests.

Acute toxicity:

Based on available data, the classification criteria are not met, as it does not contain substances classified as harmful if swallowed (wood glue).

Corrosivity / Irritation:

Based on available data, the classification criteria are not met.

Inhalation:

Based on available data, the classification criteria are not met. Neither the glue or surfacing oil evaporate in regular living temperatures. 

Skin and Eye contact:

– Skin contact: Based on available data, the classification criteria are not met.
– Eye contact: Based on available data, the classification criteria are not met.

CMR effects (carcinogenicity, mutagenicity, and toxicity for reproduction):

Carcinogenicity:

Based on available data, the classification criteria are not met, as it does not contain substances classified as dangerous for this effect.

Sensitization:

According to available data, the materials do not cause sensitization or symptoms.

Physical assessment

Wood is naturally hard and blocks can cause damage if thrown at people. However, the tasks of the activity cards do not advise throwing the blocks and it is recommended that they are used together with an adult. And actually, this is advised not because of safety reasons, but to bring adults and children together overplay. The blocks do not break into small parts in normal use and are designed to be too big to be swallowed.

As the product has details put together with wood glue, the product poses a choking hazard and thus is not suitable for children under 3 years of age. However, in normal use, the parts do not come loose, which has been verified, for example, by impact and throwing tests. 

There are no sounds from the blocks and as part of the play, the sound is moderate. According to the instructions, play moments that may cause noise should be done on the carpet and when listening to sound samples, users should use settings and volume that don’t cause harm to hearing.

Toys are stored in an ecologically produced bag, which also does not emit loose parts, chemicals, sounds or pose a danger to its user.

The blocks and surfacing material are water-resistant, but it is not advised to keep the blocks in water contact often or for a long period of time. However, the surfacing does not come off from occasional water contact.

Mechanical evaluation

The toy is made entirely of wood and does not contain other materials or loose parts, rotate or move. There are no mechanical parts in the toy.

Electrical properties

The toy is made entirely of wood and has no electrical properties.

Flammability hazards

Being made of wood, the toy can of course catch fire, but not by itself. However, toys should not be stored in the immediate vicinity of places with a fire risk.

Hygiene hazards

Natural bacteria can remain on the surface of the toy during use, which is of course good to consider. When using toys in public places, especially those that have not been visited before, it is recommended to wash your hands before and after playing. The toys have been treated with Osmo top wax or another similar natural oil-based finishing, which allows the toys to be wiped with a damp cloth and general detergent or, for example, a small amount of Fairy.

Hazards associated with radioactivity

The toy is made entirely of wood and does not contain any other materials or loose parts.

Manufacturing

The toys are manufactured in Finland by Tyvi Oy in Jyväskylä. The wood comes from nearby forests and old yard trees, which are dried naturally – not mechanically dried. The wood is processed and the toys are finished at Tyvi Oy’s premises in Jyväskylä.

Activity cards are printed by Sokkeli Oy in Finland, Helsinki. Sokkeli Oy is a family company and utilizes materials and inks that are of the best quality, least toxic, and sustainable sources.

Cotton bags come from Axon Profil from Sweden and are made from recycled cotton.
