Incompatability: Avoid storing hydrochloric acid anywhere in the vicinity of formaldehyde. A potent carcinogen, chloromethoxychloromethane, is formed when hydrochloric acid and formaldehyde react in air. This serious potential problem further emphasizes the need to store hydrochloric acid in a dedicated acid cabinet.

Safety Purchase Suggestion: Buy and store only small package sizes and small quantities. For safety reasons, Flinn offers larger sizes of hydrochloric acid and other hazardous substances in PVC-coated bottles. We have attempted to price the products in these safer containers as low as possible. In the event of breakage, acid and glass shards are safely retained in a PVC outer envelope. The PVC-coated bottle is a safer package for science teachers.

SPECIAL STORAGE TIP: Hydrochloric acid fumes a lot—particularly when warm. These fumes are responsible for most of the corrosion damage in your acid storage area. To solve this problem, store hydrochloric acid bottle(s) in a tightly sealed plastic bag. Be sure to label the outside of the plastic bag since acid fumes will soon destroy the bottle label. Spray the label on the bottle with Krylon® plastic spray (AP1559) if you wish to preserve it.
