Flour dust is combustible, sensitising, and faces an 87.5 per cent WEL reduction. Your mill needs comprehensive controls.
Flour mills process raw grain into flour through milling, sifting, and packaging operations that generate airborne flour dust throughout the facility. The dual hazard of flour dust is that it is both a respiratory sensitiser causing occupational asthma and a combustible dust capable of causing catastrophic explosions if concentrations reach the minimum explosive concentration. The incoming WEL of 0.5 mg/m³ for flour dust and the new 1.5 mg/m³ limit for grain dust will require most mills to upgrade dust extraction, implement enclosed transfer systems, and establish comprehensive housekeeping programs to prevent dust accumulation on surfaces, ledges, and equipment.
