How can seed-dust exposure be mitigated during handling?

• A. Open equipment operation without ventilation
• B. Use enclosed equipment, moisture management, proper ventilation, and appropriate PPE
• C. Rely on natural airflow
• D. Avoid PPE entirely

Answer: (B)

Protecting workers from seed-dust exposure during handling relies on a layered approach that combines how equipment is designed, how the process is controlled, and personal protective measures. Using enclosed equipment keeps seeds and dust contained, so fewer particles become airborne. Managing moisture reduces dust generation by making seeds clump together and by dampening particles. Proper ventilation actively removes dust from the work area, lowering the concentration workers breathe. And wearing appropriate PPE adds a final shield for any residual exposure.

In contrast, opening equipment without ventilation allows dust to escape into the surrounding area, relying on unpredictable airflow to disperse it. Relying on natural airflow isn’t a reliable method to control dust levels. Avoiding PPE leaves workers unprotected even when other controls are in place.
