HSE information sheet
Health surveillance
The primary purpose of health surveillance is to protect the health of individual employees who may have become sensitised to isocyanates. The results of the health surveillance exercise can also be used as one means of monitoring the effectiveness of the control and protection measures in place. Positive results from health surveillance may indicate that excessive exposure has occurred in the workplace and this highlights the need to review the control measures in place.
If people are removed from work with isocyanates soon after they develop the allergy then it is likely that no persistent lung problems will occur. If, however, they continue to work with isocyanates then they may well develop long-term irreversible chest problems. Health surveillance can assist in identifying early signs of asthma and action can therefore be taken to prevent longer-term effects.
Health surveillance is required for those exposed to vapour and spray from isocyanate-containing paints during such activities as mixing, spraying and drying.
It is likely that a risk assessment will suggest that a high level of health surveillance would be appropriate for personnel who are exposed to isocyanates. This could be carried out by an occupational health nurse or medical practitioner who is familiar with the risks of the process and principles of health surveillance. The health surveillance should consist of:
People working with isocyanate-containing paints who are under health surveillance should be trained to recognise the symptoms of sensitisation and to report them to a named responsible person. Early action can then be taken to initiate further medical investigation and, if appropriate, make changes to the work process to protect their health.
Recognition of unsuspected cases of occupational asthma
Sickness absence records should be scrutinised from time to time to identify absence due to respiratory disease. Complaints of work-related symptoms among employees or leavers should be investigated. A runny nose or sore eyes which appear to be linked to spraying operations may be the first signs that exposure is too high.
Reporting cases
Employers are required to report to the Health and Safety Executive under the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 1995 (RIDDOR) any medically confirmed cases of occupational asthma arising from exposure to isocyanates.
Further advice
The Employment Medical Advisory Service (EMAS) is available to provide advice on all aspects of occupational asthma arising from the use of isocyanate-containing paints. Details of providers of health surveillance may be obtained from your local EMAS office, trade associations such as the Retail Motor Industry Federation and the Vehicle Builders and Repairers Association and trade journals such as Body and Bodyshop.
