Collection: Safety Cabinets for Chemical Liquids

Yes, but only if the closet is structured with separate and stagnant internal compartments.It is absolutely not allowed to store them together on open shelves of the same compartment.

Acids and bases are chemically incompatible. If stored in the same confined environment, the respective vapors can react with each other, creating crystalline salts that block ventilation systems, corrode the closet structure, and, in the most severe cases, can generate hazardous exothermic reactions or release toxic gases.

• The correct solution:If you need to store both acids and bases in the same location, you must use a combined or compartmentalized closet. This type of cabinet is divided vertically or horizontally into two or more isolated cells, each equipped with its own independent collection basin and its own connection for aspirating vapors.

The difference lies in the level of resistance to corrosion caused by different types of chemical agents:

• Zinc-coated steel (with powder-coated anti-acid finish):It is the standard and versatile choice for most industrial and school laboratories. It offers excellent mechanical and structural resistance and is ideal for storing solvents, general chemicals, and low-concentration acids/bases. However, if exposed to highly concentrated and volatile acid vapors, the coating may scratch or deteriorate over time, exposing the steel to rust.
• High-density polyethylene (HDPE) or PVC entirely plastic: These cabinets do not contain any exposed metallic parts. They are specifically designed for the storage of highly corrosive and aggressive substances (such as concentrated hydrochloric acid, sulfuric acid, or nitric acid). Polyethylene and PVC are chemically inert to these attacks, ensuring that the structure does not deteriorate or corrode ever, eliminating the risk of structural collapses. Highly corrosive and aggressive substances (such as concentrated hydrochloric acid, sulfuric acid, or nitric acid) (like concentrated hydrochloric acid, sulfuric acid, or nitric acid). The polyethylene and PVC are chemically inert to these attacks, ensuring that the structure does not deteriorate or corrode ever, eliminating the risk of structural collapses.

The glass doors are designed for a specific use in chemical, pharmaceutical, or school laboratories, where immediate visibility of reagents is fundamental for operational efficiency and reduces the time it takes to open the cabinet (limiting the release of vapors). immediate visibility of reagents is fundamental for operational efficiency and reduces the time it takes to open the cabinet (limiting the release of vapors).

At a safety level for pure chemical risk (corrosive and toxic), they offer excellent performances because:

• Security glass layers (visarm) are exclusively produced inSecurity (visarm) glass layers are exclusively produced inAbout tempered glass. In the event of accidental impact or breakage, the glass does not shatter into sharp fragments, but cracks and remains compact to retain products inside.
• The profiles of the frame are anyway realized in coated steel or acid-resistant material equipped with sealing gaskets.

Attention to fire classification: If the glass-fronted cabinet is to store substances that are either chemical/corrosiveeitherHighly flammable, the standard glass door is not suitable. In that case, a certified EN 14470-1 (Type 90) cabinet is needed, which, if equipped with fire-rated glass, uses special multi-layer fire-rated glass certified.

The basin at the bottom has the task of containing the immediate emergency, preventing the liquid from spilling onto the floor or polluting the environment, but the chemical product must never be left standing in the basin.

Here is the correct procedure to follow immediately, wearing suitable PPE (acid-resistant gloves, protective glasses, apron):

1. Neutralization or Absorption:Never use common rags or sawdust (which could react with the acid or ignite). Use specific powder neutralizers for acidic or universal/chemical absorbents (such as sepiolite or specific absorbent cloths for aggressive substances).
2. Removal and Cleaning: Once the liquid has been solidified or absorbed, remove it with anti-static tools and plastics. Clean the tank thoroughly with water and suitable detergents to remove any corrosive residue that may damage the protective coating of the tank itself.
3. Disposal: The exhausted and contaminated absorbent material must be collected in designated bags or containers for hazardous waste and disposed of according to prevailing environmental regulations (appropriate CER codes), never disposing of it in regular company waste.
