  • The maximum allowed working opening is 30 cm. This should be marked on the cupboard.
  • The air removal speed in the cupboard should be regulated to 0,50 m/s (+/- 0,05 m/s). The air removal speed should be checked and adjusted during the yearly technical inspection.
  • The lower limit for air removal speed is 0,40 m/s. Cupboards equipped with alarms should sound the alarm when the air removal speed is lower than 0,40 m/s.

If the air removal speed falls below 0,40 m/s, the cupboard should be closed and marked with a warning. The air removal speed in the fume cupboard should be checked during self inspection and the yearly technical inspection
