Fire-resistance Safety Cabinet for Weakly Corrosive Chemical

Corrosive reagents such as hydrochloric acid and sodium hydroxide belong in a blue corrosive safety cabinet. Blue identifies the hazard class on sight and the interior is lined with HDPE/PP plastic or an epoxy anti-corrosion coating, so the reagent attacks the liner rather than the steel shell. A blue corrosive chemical storage cabinet of this type does not require grounding - it is deliberately left ungrounded to avoid electrochemical corrosion. For small reagent bottles in a teaching lab or a bench-side station, the 4 gal model works as a small acid cabinet, while plating shops and bulk chemical stores usually specify from 45 gal upward.

A: Customised colours are available for bulk orders. Provide a RAL code and the coating is matched to it, but note that custom colours may extend lead time by 2-3 weeks for coating and testing.

A: A monthly inspection is recommended: check the grounding connection where one is required, confirm the door seals and lock operate correctly, and inspect the sill and liner for cracks or corrosion. Any liner damage on a corrosive cabinet should be repaired or replaced before the cabinet goes back into service. The same routine applies to a combustible storage cabinet or a yellow cabinet for chemical storage - the difference is that grounded models also need the earth connection re-tested at each check, since that is what prevents static build-up around flammable liquids.
