Potential Health Hazard

I ordered a number of chemicals from A2BChem. While the chemicals themselves were fine, many were missing safety hazard signs, and at least two were shipped without ice packs despite being stable at fridge temperature. Additionally, at least one chemical is volatilizing through the unopened containers, evident by a headache whenever I'm around the chemical batch. The prices here are fantastic, but the chemical handling is suspect, and it's difficult to track the quality control to confirm high-quality chemical standards. I won't be ordering from this company again.
