Spanglish

I came across this small sign while I was walking around campus. What drew my attention to it was the spanish translation and grammar. I couldn't believe how there could be such a careless mistake on a professional sign that is used around campus. The error is ridiculous and it was probably done by someone who is ignorant to the fact that english is not the only spoken language in the U.S and the spanish translation is just as necessary. I guess their reasoning was to replace the last two letters of the word chemical and replace them with OS to make it spanish. There are English to Spanish dictionaries now a days!
