YataLogic’s analysis
The key point of this case
Use one label to signal stopping when a danger is noticed and checking with an adult or advice service. The label alone does not provide a medical assessment of toxicity.
From official information
Officially documented uses
- The Pittsburgh Poison Center states that Mr. Yuk was created in 1971 and is used to educate children and adults about poison prevention and raise awareness of the Poison Center.
- Each sticker displays the nationwide Poison Help number, and millions are distributed annually.
- The official download page explicitly instructs adults to teach children that Mr. Yuk means NO: do not touch, taste or smell.
YataLogic’s view of the challenge
Which challenge does this relate to?
Children cannot judge the danger of chemicals or cleaning products by appearance alone or distinguish items they should not touch, taste or smell. Adults may also struggle to immediately recall where to seek advice about poisoning.
