Workers exposed to airborne flour dust are at risk of health effects such as occupational asthma, respiratory sensitization, and allergy to flour dust. Effective control methods are available to protect workers from exposure to flour dust. This document outlines responsibilities for employers, supervisors, and workers. It will also help employers develop an exposure control plan (ECP) for flour dust.

Note: The guidance provided in the table “Acceptable control methods” is currently under review.
