Posted By Marilyn Martin Hi Tony It would be useful to know what type of information you needed and what for. Is it for risk assessment, consideration of controls or in relation to a project? There are several HSE Books publications that are useful to help you understand occ. asthma and seek to control potential asthmagens in the workplace. You can also seek advice from occupational health staff. NIOSH web site in the U States has a lot of very useful research info. - just be aware that their legislation is a bit different to UK. If you let me know by return to your thread if you need any additional help, I will get back to you. Marilyn Martin
