Isopropyl Alcohol Allowed in Warehouse?

9/8/2026

Looking at storing upwards of 100 skids of isopropyl alcohol in consumer commodity bottles and in cartons. These would be in 475 mL and 950 mL bottles. The building is not a dangerous goods warehouse.

Is this permissible?

Thanks in advance.

Does the building have sprinkler coverage or other fire protection for that commodity in the code which it was built under?

It doesn't sound like it does. But we'd need to know.

Permissible - Maybe

Does the building now require sprinklers? - Most likely

Did the Building Design (Construction Type, etc.) consider that this commodity would be placed in this facility? - Can't Answer - This can be the a major problem that will need to be determined.

Need to review the SDS and also understand the concentration of the product that you plan to store in this facility. Any other hazardous materials being stored within?

Isopropyl alcohol is classified as a Class 1B flammable liquid due to its low Flashpoint (-53 F).
Because it is water-miscible ( polar) solvent standard fire rules for petroleum based liquids do not cleanly apply.
The specific fire sprinkler design criteria are dictated by NFPA 30 (Flammable and combustible liquids code ) chapter 16.

Unfortunately, this is too general of a question to answer and would require detailed knowledge of the existing building and a thorough code analysis to determine if this storage would trigger a change in occupancy to a hazardous occupancy. There is also the question of if the building's sprinkler system is designed for storage of flammable liquids.

Would need to know what Building/Fire Code is applicable and total quantity of the product being stored.

The MAQ for a 1B is 130 gallons but can be increased by sprinkler protection and/or storage in approved cabinets.

Storage above the MAQ quantity will make it an H Use under the IBC/IFC.

There is an option to create Control Areas and separate the materials if greater than the MAQ. You can create 4 Control Areas on the Ground Floor and less Control Areas and quantity of IPA as you ascend or descend in the building. The Control Areas are required to be separated by 1-hour rated construction. If you are above the Ground Floor you may have to rate the floor slab for 2-hoiurs depending on the building and other conditions related to the building and the Control Areas.
As already stated if you exceed the Maximum Allowable Quantity identified in the IBC/IFC you may have to create an area or room or the entire building as a "High Hazard" Building (H). this requires a bunch of details as outlined in the IBC/IFC.
