Occupational asthma is a disease categorised by breathing problems or chest tightness caused by substances that you may come across at work.

The condition can take weeks, months or even years to develop, depending on the person and the substance.

The symptoms of asthma include attacks of coughing, wheezing, shortness of breath and tightening around the chest. Some sufferers become so debilitated that they cannot work again.

Developing a sensitivity to dust or a chemical is the most common cause of occupational asthma. Numerous substances used in the workplace can trigger allergic reactions including wood dust and flour and grain. There are over 200 other respiratory sensitisers and more are being identified all the time.
