Types Of Chemical Storage Cabinets: Which Is Right For You

Understanding Chemical Storage Cabinets

Chemical storage cabinets are not just ordinary storage units—they are purpose-built to keep hazardous substances contained, organized, and isolated from people and surroundings. These cabinets are constructed using fire-resistant materials and are equipped with safety features like leak-proof sills and locking mechanisms. Their main function is to limit chemical exposure, minimize vapor release, and reduce the potential for accidents in the event of a spill or fire. Selecting the appropriate chemical safety cabinet also depends on the physical state of the chemical, such as whether it is a liquid, gas, or solid, as this influences ventilation and containment requirements.

At PSA Laboratory Furniture, we believe in helping our clients make informed choices by evaluating all aspects of their laboratory setup. That includes determining how the chemicals interact, how frequently they’re used, and where the cabinet will be placed to support both workflow and compliance.

Flammable Liquid Storage Cabinets

Flammable liquid storage cabinets are engineered to store substances that can ignite easily. Typically constructed from double-walled steel with insulating air space, these cabinets are designed to withstand high temperatures, providing a buffer against external fires. They often feature self-closing doors, leak-proof sills, and vents with flame arresters. The color coding for these cabinets is usually yellow, indicating their purpose for flammable materials. It's important to store only compatible flammable liquids together to prevent dangerous reactions.

Corrosive Substance Storage Cabinets

For acids and bases, corrosive substance storage cabinets offer protection against chemical damage. These cabinets are often made from materials like polyethylene or coated steel to resist corrosion. They include features such as spill containment trays and ventilation systems to manage fumes. Blue is the standard color for these cabinets, signaling their use for corrosive substances. Proper segregation of incompatible chemicals, such as separating acids from bases, is essential to prevent hazardous reactions.

Toxic and Poisonous Chemical Cabinets

Storing toxic chemicals requires cabinets that prevent exposure and contamination. These units are designed to be airtight and may include features like locks and warning labels to prevent unauthorized access. The interior is often lined with materials that resist absorption, and the cabinets may be equipped with ventilation to prevent the buildup of toxic fumes. White or gray is commonly used to denote cabinets for toxic substances.

Oxidizer Storage Cabinets

Oxidizers are dangerous not because they burn, but because they make other substances burn more easily. This makes storing them near organic compounds or flammable materials a serious hazard. An oxidizer storage cabinet is built to withstand this risk by incorporating non-reactive surfaces and durable seals that reduce the likelihood of cross-contamination. These cabinets are usually isolated from general storage areas and often positioned with specific clearance from electrical equipment or heat sources.

To support laboratory teams, we design our oxidizer cabinets to include clear hazard signage, built-in airflow options, and a structure that discourages overcrowding. This allows users to identify contents quickly and avoid storage mistakes. Color-coded and clearly labeled, these units contribute to a safer and more organized work environment.

Pesticide and Agricultural Chemical Cabinets

Pesticides and herbicides contain active ingredients that can be toxic, corrosive, or flammable. The risks aren’t just limited to physical contact; vapors and spills can contaminate surrounding surfaces or harm personnel. Cabinets for storing these substances are designed to contain leaks with sump trays and to limit vapor release with optional venting systems. They're also often required in agricultural labs, school research centers, and public maintenance departments.

At PSA Laboratory Furniture, we offer pesticide chemical safety cabinets that not only keep chemicals isolated but also improve user safety through visual cues like bold green coloring and caution signage. These features help promote regulatory compliance while making it easier to train team members on proper use.

Combination Storage Cabinets

When you don’t have space for separate cabinets for flammables, corrosives, and toxics, a combination cabinet can offer a compact yet reliable solution. These units feature multiple compartments, each built with different liners and seals tailored to the hazard class it holds. Internal barriers prevent fumes from mixing and stop reactive spills from crossing into other areas. Combination cabinets are especially useful in academic labs, mobile testing environments, and clinics where sample diversity is high but storage space is limited.

Our combination chemical storage cabinets at PSA Laboratory Furniture are engineered with high-grade materials that support chemical separation and long-term durability. With thoughtful design, even a small lab can stay compliant and safe without sacrificing workflow efficiency.

Selecting the Right Cabinet for Your Needs

Choosing the appropriate chemical storage cabinet involves assessing the types of chemicals used, their quantities, and the specific hazards they present. Consider the following factors:

• Chemical Compatibility: Make sure that the cabinet material is compatible with the chemicals stored to prevent reactions.
• Volume and Size: Select a cabinet that accommodates the volume of chemicals without overcrowding, allowing for proper air circulation.
• Ventilation Requirements: Some chemicals require cabinets with ventilation systems to manage fumes and vapors.
• Regulatory Compliance: Verify that the cabinet meets local and international safety standards and regulations.

Accessibility and Security: Consider cabinets with locking mechanisms to prevent unauthorized access and make sure that they are easily accessible to authorized personnel.
