UB-90 Chemical Safety Cabinet

The UB-90 is an under-bench chemical safety cabinet with 90 minutes of fire resistance, sized to fit beneath a laboratory bench or fume cupboard. Eleven models across six sizes run from 106 to 430 litres, 600 to 800 mm high, 593 to 1402 mm wide and 574 to 752 mm deep.

What a 90-minute fire rating means

A fire-rated chemical cabinet is built to hold its contents below ignition temperature for a stated period once a fire starts around it, giving people time to leave the building and the fire service time to arrive before the stored substances make the fire worse. Ninety minutes is the longer of the two ratings we stock. Whether it is required at your premises is a question of national workplace-safety law and your own fire risk assessment, so confirm the requirement with your safety officer or local authority before ordering.

Drawers or wing doors

Each size is available with drawers or with wing doors. Drawers bring containers forward to the operator, which suits small bottles that are lifted in and out often; wing doors open the full width for larger containers and for trays. Where a taller cabinet is workable, the Q-90 range gives the same 90 minutes in a full-height format up to 903 litres, and the Q-30 range is the same tall cabinet at a 30-minute rating.
