Pharmaceutical warehouses impose even stricter container requirements than food: cages must enter cleanrooms, be easy to disinfect, shed no particles, and meet GMP expectations for storage containers. Cots brought straight from a general workshop into the warehouse become audit findings through flaking paint, dust and rust.
For general areas, choose cages that are fully powder-coated or hot-dip galvanized, with smooth, gap-free surfaces. For cleanrooms or Grade D backgrounds, stainless-steel 304 cages are recommended, with rounded-corner welding and polished inner and outer walls so they can be wiped down with alcohol and disinfectant.
The cage structure must minimize dust traps: regular, uniform mesh openings, no protruding bolts or wire ends, and a bottom grid made removable or easy to flush. Cages inside the cleanroom must be fixed in number, numbered, washed periodically, and logged in a cleaning record, managed separately from material batches.
Pharmaceutical materials are most vulnerable to contamination and mix-ups: one cage, one code, with material labels and status tags hung on the outside, and released, on-hold and returned goods stored in separate zones. Do not stack cages more than two layers high to prevent tipping, and keep goods inside the mesh so outer packaging is not scuffed during transport. Washed cages must drain in the cleaning area and be confirmed free of water and lint before entering the cleanroom.
