Engineered Chemical Storage Solutions for Compliance and Safety
Selecting the right chemical storage room or building is critical, not only to protect employees and assets but also to satisfy insurers, auditors, and authorities having jurisdiction (AHJs). With decades of engineering expertise, DENIOS helps facility managers, EHS leaders, and engineers design storage solutions that pass every compliance check, including OSHA 1910.106, NFPA 30, EPA SPCC (40 CFR 112), and FM approval, if needed.
What Is the Best Way to Store Hazardous Chemicals?
Safe chemical storage starts with segregation, containment, and ventilation. Whether you need an operational chemical storage room or a non-occupancy storage unit, DENIOS designs buildings to meet or exceed OSHA, NFPA, and FM Global standards.
Best Practices for Chemical Storage
- Group chemicals by compatibility (flammables, corrosives, oxidizers, toxics).
- Store flammable materials inside a fire-rated chemical storage building away from ignition sources.
- Use spill containment systems such as sumps or pallets.
- Maintain ventilation and climate control for temperature-sensitive chemicals.
- Conduct routine inspections and safety training.
Hazmat Storage Buildings vs. Flammable Storage Buildings
Hazmat Chemical Storage Buildings (Non-Fire Rated)
Ideal for corrosives, toxics, and reactive materials.
Indoor or outdoor use with shelving or racking.
Capacity: 1–12 IBC totes or up to 48 drums.
Options: passive/active ventilation, heating, cooling, dry chemical suppression.
Forklift-accessible and delivered ready for placement.
Flammable Storage Buildings (Fire Rated: 2- or 4-Hour)
Required for flammable and combustible liquids.
Built to NFPA 30 and OSHA 1910.106.
2-hour or 4-hour fire-rated construction.
Includes fire detection, mechanical ventilation, and roll-up or swing doors.
Options: FM approval, explosion-proof fixtures, and climate control.
Which Chemical Storage Solution Is Right for You?
Ask yourself:
Will employees be working inside (operational) or is it for storage only?
Are the chemicals flammable, corrosive, or temperature-sensitive?
Do you need indoor, outdoor, or mobile placement?
How many drums or totes do you need to store?
Do you have a Safety Data Sheet (SDS) to keep track of the hazardous materials you store and their locations?
Have your employees been trained on how to handle hazardous materials?
DENIOS can help design:
Non-occupancy racking and shelving buildings with full-face forklift doors for safer handling
Occupancy-ready units with PPE stations, spill containment, and ventilation
Climate-controlled containers for sensitive or reactive chemicals
FM-Approved Chemical Storage Buildings for full compliance

Built for Compliance: OSHA, NFPA, EPA, and FM
Chemical storage isn’t one-size-fits-all, and neither are the regulations. DENIOS buildings are engineered to meet or exceed key U.S. standards, including OSHA 1910.106, NFPA 30, OSHA 1910.120, and EPA SPCC (40 CFR 112), as well as optional FM Global certification. From fire-rated construction to secondary spill containment, every detail is designed with code compliance in mind.
Our solutions are trusted across various industries for a wide range of applications, including indoor and outdoor hazardous material storage, flammable liquid segregation, waste accumulation areas, temperature-controlled storage, and the handling of corrosive substances.
With DENIOS, you’re not just getting a building—you’re getting a partner. We bring decades of experience, industry-specific expertise, and fully custom engineering to every project. Whether you need assistance with SDS documentation, floorplan design, or regulatory approvals, our team supports you from planning through installation and beyond.
Frequently Asked Questions About Storing Hazardous Chemicals
What is the safest way to store hazardous chemicals in a facility?
The safest way to store hazardous chemicals is in a purpose-built, custom-engineered chemical storage building or container that complies with OSHA, NFPA, and EPA standards. Proper chemical storage involves segregation by compatibility, secondary containment, mechanical or passive ventilation, secure access, and routine inspections to prevent spills, fires, or exposure risks.
Do I need a fire-rated chemical storage building for flammable liquids?
Yes, if you're storing flammable or combustible liquids, a fire-rated chemical storage building is typically required by OSHA 1910.106 and NFPA 30. DENIOS offers custom-engineered fire-rated buildings with 2- or 4-hour protection, as well as fire suppression systems, explosion-proof fixtures, and FM approval options to meet compliance and safety needs.
What regulations apply to chemical storage buildings in the U.S.?
Key regulations include OSHA 1910.106 for flammable liquids, OSHA 1910.120 for hazardous substances, NFPA 30 for fire safety, and EPA’s SPCC Rule (40 CFR 112) for spill prevention. Compliance may also require local AHJ approval and adherence to FM Global standards, depending on your application.
How many drums or IBC totes can a DENIOS chemical storage building hold?
DENIOS custom chemical storage buildings are designed to accommodate a wide range of capacities—from 1 to 12 IBC totes or 1 to 48 55-gallon drums. Configurations include single- or multi-tier racking systems and can be customized based on your footprint, handling requirements, and ventilation needs.
What is the difference between a hazmat chemical storage building and a flammable storage building?
A hazmat storage building is non-fire-rated and ideal for corrosive, reactive, or toxic chemicals that do not require fire protection. A flammable storage building includes 2- or 4-hour fire-rated construction, fire detection, and explosion protection—required when storing flammable or combustible liquids.
Can DENIOS help me stay compliant with OSHA and NFPA codes?
Yes. DENIOS designs every chemical storage building to meet or exceed OSHA, NFPA, and EPA codes. Our engineering team works closely with you to ensure your solution meets all regulatory requirements, including structural, electrical, fire safety, and environmental compliance, tailored to your specific facility.
What are the key features of a compliant chemical storage unit?
Compliant chemical storage units typically include:
Fire-rated walls and ceilings (if needed)
Spill containment sumps
Mechanical or passive ventilation
Explosion-proof electrical systems
Fire suppression and detection systems
Forklift access and racking for totes or drums
DENIOS buildings are fully engineered to integrate all of these safety-critical features.
How much does a custom chemical storage building cost?
The cost depends on size, materials, fire-rating, and regulatory requirements. Basic non-fire-rated units start in the low six figures, while fully equipped, fire-rated buildings can range from several hundred thousand to over a million dollars. DENIOS provides expert consultation to deliver the right solution within your budget and compliance scope.
What industries need engineered chemical storage buildings?
DENIOS solutions are trusted by companies in chemical manufacturing, pharmaceuticals, energy, aerospace, defense, food and beverage, education, and municipal sectors. Any facility handling flammable, corrosive, or hazardous materials can benefit from engineered storage to ensure safety, compliance, and operational efficiency.
How do I choose the right chemical storage solution for my facility?
Choosing the right solution depends on the types of chemicals, volumes, fire safety needs, and facility layout. DENIOS helps you assess all key factors—regulations, storage capacity, ventilation, fire rating, and placement—to design a custom-engineered chemical storage building that meets your exact requirements.
