Flour Dust

Flour dust may look harmless, well in fact it can cause serious lung diseases like Asthma which can result in attacks of breathlessness and tightness in the chest.

Other side effects of using flour and inhaling its dust include; irritation to the eyes or nose and occupational dermatitis.


Once a person becomes sensitised to flour dust, exposure to even a very small amount of it can bring on an asthmatic attack, it is then possible that the person will never be able to work in a bakery again.

It is estimated that 95,000 people working in the UK baking industry encounter it daily.

As an employer, you are responsible for taking effective measures to control exposure and protect health.


Flour dust has a legal limit called a ‘workplace exposure limit’ the WEL is set at 10 mg/m3 (averaged over an 8-hour working period).

Once an assessment has been carried out to measure the exposure levels any actions should then be taken to either reduce or control exposure as part of an ongoing monitoring regime.

In addition to ensuring the WEL is not exceeded, flour dust is classed as a respiratory sensitiser and therefore employers should make all efforts to reduce exposure to as low as reasonably practicable. There are a number of good practices that can be implemented to control exposure.
