Safety Labels

What we have is about 38 Labels that need to be recreated in a vector base format. I have the existing labels that i have scanned in at 300 dpi and some of them need changes. I have scanned it with a ruler to show scale of the size of the labels. I use corel draw myself but i have illustrator as well. Any other details feel free to contact me. I have attached a sample file. I have the complete pdf that can be downloaded.
