After excellent feedback from delegates at last year's conference, the respected journalist and TV presenter will chair IOSH 2018.
Cathy has fronted many TV documentaries and hosted GMTV's The Sunday Programme. She has also written for The Daily Telegraph and served as Chief Political Correspondent for the Financial Times.
The event is being held from 17-18 September at the ICC in Birmingham, UK, on the theme 'Shape a new world of work'.
Sue Bull, IOSH's Conference Producer, said: "I am delighted that Cathy will join us again for IOSH 2018 as our conference chair.
"She was highly rated by delegates who attended the IOSH annual conference last year, with 98 per cent saying she was good or better; high praise indeed. So I didn't hesitate in inviting her to chair again.
"Working with Cathy before and during the two days of the conference was a fantastic experience. She was very easy to work with, a consummate professional throughout, and did an exceptional job by being extremely well planned, adaptable and prepared across both days.
"She was really interested in the conference and met all the mainstage speakers beforehand to go through their introductions to ensure they were at ease and knew what to expect. Cathy has all the qualities, skills and knowledge you need for a good conference chair and I am looking forward to working with her again enormously."
The conference will combine presentations from motivational and industry experts with practical and interactive track sessions and networking opportunities.
The four tracks will be:
Track A - Enhancing your professional skills
Track B - Health, wellbeing and workplace performance
Track C - Effective health and safety management
Track D -- The changing world of work
