Melstøv

Melstøv refers to fine particles of flour or other dry food ingredients suspended in the air, typically encountered in bakeries, mills, and food processing plants. These airborne particles can originate from various stages of production, including milling grains, mixing dough, and packaging finished products.

The composition of melstøv varies depending on the ingredients being processed. It can include wheat flour, rye flour, cornmeal, sugar, cocoa powder, and other finely ground substances. The size of these particles is generally very small, often in the micrometer range, which allows them to remain suspended in the air for extended periods.

Exposure to high concentrations of melstøv can pose health risks to workers. Inhalation of these particles can lead to respiratory issues such as occupational asthma, bronchitis, and rhinitis. Individuals with pre-existing respiratory conditions may be particularly susceptible. Allergic reactions to specific flour proteins are also a common concern.

In addition to health hazards, melstøv can also present a fire and explosion risk. Finely divided organic dust, when suspended in the air at sufficient concentrations and exposed to an ignition source, can combust rapidly, leading to dust explosions. This is a significant concern in environments where large quantities of dry, combustible ingredients are handled.

To mitigate these risks, control measures are implemented in industrial settings. These include ventilation systems, dust collection equipment, good housekeeping practices to prevent dust accumulation, and the use of personal protective equipment such as respirators. Regular monitoring of airborne dust levels is also crucial for ensuring a safe working environment.
