Flour Dust Monitoring
Inhalable flour dust exposure assessment in bakeries and food processing
What Is Flour Dust Monitoring?
Flour dust monitoring measures inhalable dust exposure in bakeries, flour mills, pasta factories, and food processing facilities. Flour dust is a potent respiratory sensitiser and the second most common cause of occupational asthma in Australia after isocyanates.
The WES of 0.5 mg/m³ (inhalable fraction, TWA-8h) is one of the lowest dust limits, reflecting the high sensitisation potency. Alpha-amylase enzyme additives in improver mixes further increase the asthma risk. Monitoring helps evaluate LEV effectiveness and work practice controls.
How Is It Done?
Personal sampling via IOM inhalable sampler. Gravimetric analysis. Optional immunoassay for alpha-amylase if enzyme exposure is suspected.
