Occupational Health: Alveolitis in Metal Working
Health is becoming the central thrust of any HSE visit and with good reason, health causes a huge impact on individuals and a massive strain on our NHS. However, not all safety 
professionals are aware of these risks well enough to control them and that’s where expert, external, independent advice can be invaluable.
Alveolitis is a condition of the lung caused by the inhalation of the mist created by metal working fluid when machining – particularly at higher speeds.
The Hazards of Metal Working Fluids (MWF) Alveolitis
Exposure to MWF can be hazardous in several ways but dermatitis from skin contact and lung problems from inhalation are the two major issues. Biocides are often introduced into MWF’s to stop bacterial growth and this gives the clue about what can happen to the lungs when a fine mist is inhaled by workers.
Over a period of time workers may develop a number of ill health conditions including;
- bronchitis;
- irritation of the upper respiratory tract;
- occupational asthma;
- or, most seriously, extrinsic allergic alveolitis (EEA).
If you use MWF then seek to control exposure by minimising the volume and rate of delivery at the cutting point or seek to capture mist or enclose it within CNC machines. If you use a small bright torch with a focusing beam you may be able to seek where and how mist is rising from the process – we issue these torches for free to our clients so if you need one please ask – we’ve helped many businesses with this simple tool.
Consider also your current health surveillance provision – if you need any help and support we can provide skilled practitioners to help you put a robust health surveillance plan in place – just call us on 01453 800100 for more detail and read here for a case study involving a major aerospace company which was recently fined £800,000
