Selection Recommendation for Chemical Safety Storage Cabinets in University Laboratories
To ensure the safe storage of hazardous chemicals in university laboratories and minimize the risk of accidents, it is essential to select appropriate chemical safety storage cabinets based on chemical type, material compatibility, storage capacity, and ventilation requirements. Below is a professional selection guide.
1. Selection by Chemical Type
Chemical Type |
Recommended Cabinet Type |
Features |
---|---|---|
Flammable liquids (e.g. alcohol, ether) |
Yellow steel fireproof cabinet |
Double-wall steel structure, fireproof vent, explosion resistance |
Strong acids and alkalis (e.g. sulfuric acid, sodium hydroxide) |
Blue PP or epoxy-coated steel cabinet |
High chemical resistance, anti-corrosion, leak-proof |
Toxic chemicals (e.g. benzene, organic amines) |
Red airtight cabinet |
Airtight sealing, leakage containment |
Mixed or multiple chemicals |
Multi-compartment combined cabinet |
Independent storage areas, avoid cross-contamination |

3. Ventilation Recommendations
With central exhaust system:
Connect the cabinet’s vent ports directly to the laboratory’s central ventilation pipeline.
Without central exhaust:
Choose models equipped with built-in filtration fan modules (e.g. with activated carbon or chemical filters) to control gas emissions inside the cabinet.
