Pay Close Attention to Chemical Storage Codes Prior To Storage

Store Flammables Accordingly to Chemical Storage Codes

Do not store chemicals alphabetically or grouped by size. Chemicals can be incompatible, and therefore create hazardous situations. Be sure to do thorough research on each chemical, prior to handling or storage. Chemical Storage codes are grouped by color and hazard – providing a safe and easy way to classify your chemicals.

Chemical Storage Codes by US Chemical Storage

Red – Flammables. Segregate in a flammable or fire proof locker.

Blue – Health hazard. Inhalation, ingestion or skin absorption is toxic. Wear protective equipment before handling or storing. Store in a compliant chemical storage building.

Yellow – Reactive / Oxidizing reagent that can react violently with water, air and/or other substances. Separate from other chemicals – flammables, combustibles or non-flammables.

White – Corrosive. Harmful to skin, eyes and mucous membranes. Segregate from any other chemicals. Is volatile and can react.

Green – Slight Hazard – General chemical storage, CHEMLoc building for compliance.

Gray – Moderate hazard. Store compliantly in a completely sealed chemical storage building.

Stripes (“STOP”) – Incompatible with other chemicals, reagents, corrosives, or flammables. Separate from other chemicals.

chemical storage codes for compliance

U.S. Chemical Storage illustrates chemical storage codes and proper chemical storage techniques for flammables.

Optimally, incompatible materials such as flammables, corrosives, acids, alkalis, reagents and other chemicals should be stored separately from other chemicals. Separate chemicals with a partition wall (solid) or a separate chemical storage locker. Do not store chemicals in laboratory hoods, this can harm the fume hood. Therefore, making the fume hood non-compliant.

Cooling Systems (refrigerated, or freezer storage): Some flammables and corrosives require refrigerated or freezer storage in order to remain stable. Ordinary household refrigerators are deemed inappropriate for storage of flammable liquids because of electrical hazards. Proper explosion proof refrigerators and freezers, as well as air condition systems, are considered appropriate for chemical storage situations. Since refrigerators and freezers have no interior space for venting, flammables, corrosives and other chemicals should have tightly sealed lids.

When storing hazardous substances, make sure chemical storage codes are labeled on the chemical’s container or bag. Post hazard information where the general public can see, on the door and on the side(s) of the building.
