Warning labels are on products for a good reason. Unfortunately many people don’t read them, and in some cases they’re not adequate.
There are a lot of funny warning labels on the Internet, including one that said something like “Don’t operate hairdryer while having a shower.” Or one of the better ones floating around says about a mattress – “Warning: do not attempt to swallow.”
It’s hard to imagine anyone trying to swallow a mattress. However, the fact that the warning label states that it shouldn’t be attempted indicates the manufacturers are trying to make sure they don’t get sued for the eventuality. That’s the main reason for warning labels – to avoid lawsuits if something goes wrong with the product.
