I was thinking the same thing while listening to the interview. Being a CEO has nothing to do with the quality of your products or what went wrong. What's more important is how you plan to prevent this for happening or better yet how this happened in the first place.
Are there MSDS sheets in the office, are there written SOP's in place for employees. You can't really fault them if they're not aware of the procedures. Employees should have hands on training followed by readily available documentation should they need a refresh. Employees should be reviewed and monitored closely especially when chemicals that are being ingested into someones lungs are involved.
When you mess up a bad batch of cookies at your local bakery, you get bad tasting cookies. When you mess up a batch of e liquid, especially when the chemical mixture is as high as double the base labeled dosage - Someone gets sick. Very sick.
At the very least I hope other DIY and American e Liquid suppliers learn from this. I wouldn't want to see a habit made out of this.
