Baker & Flour Dust

Flour dust and enzymes containing additives such as amylase are the second most common cause of occupational asthma.

It can affect workers in bakeries, flour mills and kitchens.

Top tips

• Work carefully - avoid raising clouds of dust
• Either use dust extraction or respiratory protective equipment for dusty tasks.
• Never sweep up or use compressed air. Clean up using wet methods or an industrial vacuum cleaner.
• You need regular health surveillance

Reduce disease - reduce exposure to dust

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.

You can find more guidance and information on the Asthma publications pages on the HSE website.

Summary - Case Study taken by HSE

A 51-year-old maintenance fitter worked at a bakery for about 20 years. He did not smoke or have any history of asthma before he started work.

He complained of breathlessness, wheezing and coughing. This had been getting gradually worse during the past 15 years.

At work, his eyes often became red and watery. He had sneezing attacks. His symptoms were not affected by the season of the year. But he noticed that they improved when he was away from work.

A chest physician had previously diagnosed the fitter with asthma but had not connected this with his work. It was the trade union representative who suspected occupational asthma.

HSE investigation

A series of tests showed that his lung function was considerably better at weekends and on holiday. Further tests indicated a flour dust allergy.

As a result of these investigations, management arranged for him to work in less dusty areas of the plant. They improved the dust extraction and issued him with suitable respiratory protective equipment (RPE).

Effects

He remains at work using RPE to reduce his exposure, and medicine to improve his symptoms. However, his general respiratory health is poor because of chronic asthma, for which he receives disablement benefit.

Investigations revealed that this was not the only victim. Two further cases of flour dust allergy were detected.

These workers have better health, because their developing asthmas were picked up more quickly. However, they still need medication to control their symptoms. And they are likely to suffer from breathing problems for the rest of their lives.
