Flour dust and enzymes containing additives such as amylase are the second most common cause of occupational asthma. They also cause dermatitis.
It can affect workers in bakeries, flour mills and kitchens.
See COSHH Essentials for detailed advice on control.
Dust clouds arise from throwing flour, disposing of empty flour bags and brushing. Bag emptying, sieving, dough making and dusting tasks all create a lot of dust.
Work gently! Start up mixers on slow speed until wet and dry ingredients are combined. Use dredgers or sprinklers for dusting.
These case studies are all real incidents with real and often serious long-term consequences for the people involved.
You can find more guidance and information for bakers on the Asthma publications pages.
