Weighing and dispensing small quantities often release the finest fractions, right at breathing height. Good station design captures dust before it escapes and keeps recipes accurate and repeatable.

Design the workstation

Use a three-sided enclosure with the operator working at the open face. Keep scale platforms stable and free from direct airflow to avoid weighing drift. Arrange tools and containers within easy reach to avoid reaching past the capture zone.

Source capture that works

Downdraft tables draw dust down through the work surface, reducing escape across the opening. Choose a unit that maintains effective airflow under load and pair it with appropriate filtration for the hazard. Add a modest face draw from the rear or sides to bias air away from the operator without disturbing the scale.

Work technique

Pre-crease and cut a small corner in bags to control flow, then decant slowly with the spout just above the receiving vessel. Collapse bags as you go to avoid puffing. Use antistatic liners and earthing to limit static lift-off, especially with fine organic powders.

Housekeeping and checks

Vacuum surfaces frequently with an H-class unit—no sweeping or compressed air. Inspect filters, seals, and the downdraft perforations; clean before they blind. Periodically confirm capture with smoke and keep a simple log under COSHH.

Practical takeaways

• Three-sided enclosure and controlled inflow keep dust away from the face.
• Downdraft capture reduces escape at the source; protect scale accuracy.
• Slow, close decanting prevents plumes; manage static.
• Vacuum-only housekeeping and routine checks sustain performance.

With thoughtful layout and steady technique, weighing stations remain clean, precise, and low-exposure without slowing production.
